Description

Network management method and device

This application claims the priority of the Chinese patent application with the application number 202110736813.7 and the application name "Network Management Method and Device" submitted to the State Intellectual Property Office on June 30, 2021, the entire contents of which are incorporated in this application by reference.

technical field

The present application relates to the field of communication technologies, and in particular to a network management method and device.

Background technique

In a traditional network (that is, a network composed of network devices), it is generally divided into two networking modes: centralized and distributed. Centralized networking requires centralized management of network node resources, traffic, data and other information. Distributed networking, which will be independently managed on each node of the network, through mutual negotiation to realize the interaction of resources, traffic, data and other information, so as to achieve the purpose of decentralization and avoid increasing the number of master nodes (also called central nodes) power consumption and improve reliability.

In recent years, with the rapid development of mobile Internet, Internet of Things and artificial intelligence, there are more and more mobile terminal devices. At the same time, how to better integrate these mobile terminal devices with different functional performance and various connection means Connecting together to form a mobile network centered around user services has become an urgent need at present. Compared with traditional networks, mobile networks are more inclined to network for mobile terminal devices than for network devices. This requires special design for the mobility, stability, and energy consumption of each mobile terminal device. .

Currently, there are two common forms of networking for terminal devices:

Form 1. Centralized networking, that is, a master node or a form similar to a master node is used to manage terminal devices in a unified manner. For example, wireless fidelity (wireless fidelity, WiFi) access point (access point, AP) networking, Bluetooth networking, etc. are all centralized networking. Centralized networking has relatively high requirements for the capability and power consumption of the master node. Only devices such as routers and large screens can meet the requirements, while mobile terminal devices such as mobile phones, tablets, speakers, and car machines are difficult to meet.

Form 2, distributed networking, for example, distributed wireless mesh network (Mesh) networking (for example, Bluetooth low energy (bluetooth low energy, BLE) Mesh, Zigbee (Zigbee) Mesh, WiFi Mesh, etc.), this The networking mode interacts with each other in the form of service publishing and subscription, which can realize decentralized terminal device networking. This networking method has a fixed heartbeat mechanism. Therefore, fixed constant power supply devices or low-power devices are used. For mobile terminal devices, it is often necessary to turn off the screen for rest. At this time, the fixed heartbeat mechanism will cause The power consumption of mobile terminal equipment is relatively high.

It can be seen that, limited by power consumption requirements, none of the current networking methods of terminal devices can be applied to mobile terminal devices.

In order to make the embodiments of the present application more clear, some concepts involved in the present application are briefly introduced first.

1. Network topology

Network topology refers to the specific arrangement of nodes that make up the network, and is generally divided into physical, real, and online structures, or logical, virtual, and programming structures. If two networks have the same connection structure, they are considered to have the same network topology.

The nodes in the network in this application may include mobile terminal equipment. Mobile terminal devices can be mobile phones, tablets, wireless speakers, vehicles, mobile stations (mobile station, MS), user units, drones, Internet of things (internet of things, IoT) devices, wireless local area networks (wireless local area networks) , WLAN) in the station (station, ST), cellular phone (cellular phone), smart phone (smart phone), cordless phone, wireless data card, tablet PC, session initiation protocol (session initiation protocol, SIP) phone, wireless Local loop (wireless local loop, WLL) station, personal digital assistant (personal digital assistant, PDA) equipment, laptop computer (laptop computer), machine type communication (machine type communication, MTC) terminal equipment, wireless modem, with Handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices (also called wearable smart devices), device-to-device communication (device-to-device, D2D) terminals Equipment, vehicle-to-everything (V2X) terminal equipment, machine-to-machine communication (machine-to-machine, M2M) terminal equipment, Internet of things (IoT) terminal equipment, virtual reality (virtual reality) , VR) terminal equipment, augmented reality (augmented reality, AR) terminal equipment, terminal equipment in industrial control (industrial control), terminal equipment in self driving (self driving), terminal equipment in remote medical (remote medical) , terminal equipment in smart grid, terminal equipment in transportation safety, terminal equipment in smart city, terminal equipment in smart home, etc. The terminal device may also be a terminal device in the next generation communication system. The network in this application may also include non-mobile terminal devices, for example, large screens (also called TV devices), and wired speakers.

The terminal equipment in this application may also be referred to as user equipment (user equipment, UE), terminal, access terminal, subscriber unit (subscriber unit), subscriber station, remote station, remote terminal, user terminal, wireless communication device, user agent or user equipment, etc.

A node in this application may also be called a network node, a node device, a network device, a device, and the like.

Properties of a network topology include:

(1) The connection method (or connection medium) of the network topology. The connection mode of the network topology refers to the connection mode between nodes in the network topology, for example, a BLE connection, a WiFi connection, a universal serial bus (universal serial bus, USB) connection, and the like. It should be noted that the connection modes between different nodes may be the same or different, therefore, the connection modes of the network topology may include multiple types. Moreover, when performing different services, the connection mode between two nodes can be switched from one connection mode to another. Exemplarily, since mobile terminal equipment often includes multiple communication capabilities, in different scenarios, according to power consumption and service requirements, mobile terminal equipment can be connected to different nodes through different connection methods, for example, in a home In the scenario, the mobile phone and the large screen are connected through a router in the home. At this time, the connection mode of the network topology is WiFi wireless local area networks (wireless local area networks, WLAN). point to point (P2P) technology can provide an exclusive WiFi link, which can effectively reduce the problem of bandwidth reduction when the router accesses multiple nodes, so it can switch to WiFi P2P communication when the mobile phone and the large screen are performing screen projection services. Wherein, two nodes are connected through a router means that both nodes are connected to the router, and the logical data path between the two nodes is transited by the router. Since a router can connect multiple nodes, the router's bandwidth is shared by multiple nodes connected to the router. In WiFi P2P, only two nodes are interconnected, therefore, the WiFi link bandwidth is exclusive (that is, the WiFi exclusive link).

(2) The interactive mode of network topology. The interaction mode of the network topology refers to the interaction mode between nodes in the network topology, for example, the mode may be interaction through heartbeat mode or lease management mode. It should be noted that the interaction modes between different nodes may be the same or different, therefore, the interaction modes of the network topology may include multiple types.

(3) The structure of the network topology. The structure of the network topology refers to the connection structure of nodes in the network topology. Referring to Figure 1, the structure of the network topology mainly includes star, ring, tree, network and so on. In this application, the network topology after the auxiliary node is added can be referred to FIG. 2 (one auxiliary node) and FIG. 3 (multiple auxiliary nodes). Figure 1, Figure 2 and Figure 3 are only illustrations of the network topology, the number of nodes in the actual network topology, the structure of the network topology, etc. may be different from those shown in the illustrations, which are not limited in this application.

2. Heartbeat and lease management

Heartbeat means that a node (assumed to be node A) sends a small data packet (which can be called a heartbeat signal) to another interconnected node (assumed to be node B) at regular intervals, and node A is judged by the reply of node B. The method of whether the communication link with Node B has been disconnected. In this application, when node A and node B (for example, auxiliary node and main node, auxiliary node and ordinary node in the following) need to exchange information, it can be carried by heartbeat signal, or carried in the heartbeat signal to indicate the follow-up Instructions for information interaction are required, so that the information interaction can be completed in the subsequent process. In this application, for an auxiliary node, an ordinary node refers to a node other than the main node and the auxiliary node in the network. For example, for the auxiliary node A that acts as a proxy for the heartbeat function, ordinary nodes refer to nodes other than the primary node and auxiliary node A in the network, but among these ordinary nodes, there may be auxiliary nodes that act as agents for other network functions. Heartbeat is applied between nodes that have already been networked.

Lease management means that when a node (assumed to be node C) accesses another node (assumed to be node D), node C can declare online time (that is, the lease period) to node D. During the lease period, node D thinks that node C is online and can communicate with node C at any time. The lease period can be extended. For example, node C can apply to node D to extend the lease period at 1/2 or 3/4 or the end of the previous lease period, and node D can reply that the lease period extension is successful or failed.

3. Network function

The network functions involved in this application include, but are not limited to, network topology management functions, network access management functions, network device information management functions, and heartbeat functions.

Among them, the network topology management function is used to manage network topology information, and the network topology information includes one or more of the information of nodes joining the network, information of nodes leaving the network, connection relationships between nodes, and network routing information. Can contain other network topology related information. If the network topology management function is delegated to the auxiliary node, the ordinary node managed by the auxiliary node can send the network topology information to the auxiliary node, and the auxiliary node will then send the network topology information to the main node (at this time, the heartbeat function is not Auxiliary node that is proxied by an auxiliary node or an auxiliary node that acts as a proxy for the network topology management function and also acts as a proxy for the heartbeat function) or an auxiliary node that acts as an agent for the heartbeat function. Network topology information focuses on data related to the structural composition and structural changes of the network topology.

The network access management function is responsible for node access. If the network access management function is delegated to the auxiliary node, the master node can configure the auxiliary node to enable the auxiliary node to perform network access. These configurations include whether to support authentication and binding information, and access after binding and authentication Or access after successful authentication, access method (for example, which connection method is allowed to access), bandwidth for ordinary node access, etc., the auxiliary node can send the information of the node joining the network to the main node (At this time, the network topology management function is not delegated by the auxiliary node, or the auxiliary node acting as the agent of the network access management function also acts as the agent of the network topology management function) or the auxiliary node acting as the agent of the network topology management function.

The network device information management function is used to obtain and manage network device information. The network device information in this application includes, but is not limited to, node information (for example, node identification, node WiFi status (for example, whether to turn on WiFi), node Bluetooth status (for example, whether to turn on Bluetooth), node status information (such as , the node is offline or online), the screen resolution of the node that supports screen projection, etc.), the service information of the node (for example, the attribute information of the service, the data of the service, the status of the service), etc. If the network device information management function is delegated to the auxiliary node, the ordinary node managed by the auxiliary node can send the network device information to the auxiliary node, and the auxiliary node then sends the network device information to the main node (at this time, the heartbeat function Auxiliary nodes that are not proxied by the auxiliary node or that have the network device information management function also act as the agent for the heartbeat function) or the auxiliary node that acts as the agent for the heartbeat function. Network device information focuses on the information of a single device in the network itself. For convenience of description, hereinafter in this application, network device information and/or network topology information are referred to as network information. That is to say, the network information mentioned below includes network topology information and/or network device information.

The heartbeat function is used to report and synchronize network information. If the network device information management function and/or network topology management function is delegated, the auxiliary node acting for the network device information management function and/or the auxiliary node acting for the network topology management function may send the network device information and/or network topology information to The auxiliary node that acts as the proxy heartbeat function, and the auxiliary node that acts as the agent heartbeat function reports the information to the primary node according to its own heartbeat policy. Among them, the network information reporting or synchronization cycle, mode, etc. can be configured by the master node to the auxiliary node that acts as a proxy heartbeat function, that is, the heartbeat management function can be realized by the master node.

It should be noted that different network functions can be represented by different auxiliary nodes. At this time, referring to FIG. The auxiliary node A can synchronize information to the auxiliary node B, and in the case that the network topology management function is not delegated by the auxiliary node B, the auxiliary node A can synchronize information to the main node. For the auxiliary node B that acts as a proxy network topology management function, when the heartbeat function is delegated by the auxiliary node C, the auxiliary node B can synchronize information to the auxiliary node C; when the heartbeat function is not delegated by the auxiliary node C, the auxiliary node B Information can be synchronized to the master node. The assistant node D for the proxy network device information management function is similar to the assistant node B, and can be understood by referring to it. Secondary node C can synchronize information to the primary node. It should be noted that one auxiliary node can act as an agent for multiple network functions, that is, any two or more of auxiliary node A, auxiliary node B, auxiliary node C, and auxiliary node D in the figure can be the same node , at this time, the process of synchronizing information between nodes or the process of synchronizing information related to a certain node does not exist or the process is an internal realization process of the node. For example, if the auxiliary node C and the auxiliary node B are the same node, the process of synchronizing information from the auxiliary node B to the auxiliary node C does not exist or this process is an internal implementation process of the node. If auxiliary node C and auxiliary node A are the same node, the process of synchronizing information from auxiliary node A to auxiliary node B (that is, the process of synchronizing information related to auxiliary node A) does not exist.

4. Node type

The nodes in the network topology can be divided into various types of nodes according to different functions, including the main node (admin node), homogeneous routing gateway node (router node), heterogeneous routing gateway node (gateway node), end node (endpoint node). The relevant information of each type of nodes can be found in Table 1.

Table 1

In view of the above Table 1, the following two points need to be noted:

(1) The main connection mode of the network defined by the master node in Table 1 refers to the connection mode between most of the nodes in the master node. All nodes in the network can use the connection mode defined by the master node to communicate, or some Nodes use the connection method defined by the master node to communicate, and other nodes use other connection methods to communicate.

(2) The Bluetooth data packet in Table 1 refers to a data packet transmitted between two nodes connected via Bluetooth, and the WiFi data packet refers to a data packet transmitted between two nodes connected via WiFi. Heterogeneous routing gateway nodes can be connected to different nodes through different connection media. For example, heterogeneous routing gateway nodes can be connected to node A through Bluetooth and node B through WiFi. At this time, the heterogeneous routing gateway nodes will be different The terminal of the protocol is connected to the network, and the heterogeneous routing gateway node can receive the Bluetooth data packet from node A, and send the WiFi data packet to node B through conversion.

In addition to the various types of nodes shown in Table 1 above, another node type is introduced in this application, that is, auxiliary nodes. For information about auxiliary nodes, refer to Table 2.

Table 2

The nodes in the network topology can also be divided into various types of nodes according to the networking situation, see Figure 5, including non-networking nodes and networking nodes, networking nodes include offline nodes and online nodes, and online nodes include master nodes One or more of an auxiliary node, a homogeneous routing gateway node, a heterogeneous routing gateway node, and an end node. Among them, non-networking nodes can join the network through binding and authentication after discovering the network. Offline nodes can return to the network through authentication after discovering the historically joined network. The master node can be determined through elections to manage network topology information, network device information, and heartbeat policies. The auxiliary node can be determined by the master node, and an auxiliary node can act as an agent for one or more of network topology management functions, network access management functions, network device information management functions, and heartbeat functions. Homogeneous routing gateway nodes can manage homogeneous routing information. The heterogeneous routing gateway node can manage heterogeneous routing information. End nodes can manage node information, for example, homogeneous routing gateway node information, heterogeneous routing gateway node information, and so on.

The above is an introduction to some of the concepts involved in this application.

Referring to Figure 6, the network management method provided by this application includes:

601. One or more nodes (assumed to be node a, node b, and node c in FIG. 6 ) perform a network search, and establish connections with other searched nodes to form a network (which may be referred to as a first network).

The first network can include mobile terminals and/or non-mobile terminals. A node can search the network through a certain connection method, for example, it can search other surrounding nodes through WiFi or Bluetooth. The connection modes between different nodes in the first network may be the same or different, which is not limited in this application.

Before performing network search, each node can be initialized. For the node performing network search, the network search function can be turned on through initialization to perform network search. For other nodes, the network search function can be turned on through initialization to be searched. The device management module can also be enabled through initialization, so that the connection between nodes can be established through binding and authentication. The relevant description about the device management module can be found below.

Exemplarily, in a home scenario, the first network may be a distributed network composed of mobile phones, tablets, large screens, speakers, etc. The mobile phones, tablets, and large screens may be connected through a router, and the speakers may be connected to the large screen through Bluetooth. The first network may also be a network in a vehicle scene, an office scene, or other scenes, which is not limited in this application.

602. Each node in the first network negotiates to determine a master node of the first network (assumed to be node c in FIG. 6 ).

Wherein, the master node of the first network is used for centralized control of the first network. The master node can also be called the central control node, central node, etc. The master node of the first network may be a node with stronger functions in the first network, and/or a node with more user operations. For example, in a home scenario, since users will operate more mobile terminal devices (such as mobile phones and tablets), the main node of the network may be a mobile terminal device.

603. One or more other nodes (assumed to be node d in FIG. 6 ) that have not yet joined the first network join the first network through binding and authentication with the master node.

For example, assuming that the first network is a WiFi network, the user can enter the searched network access password corresponding to the first network on a node to perform binding and authentication, and join the first network. After the initial binding and authentication, if the node wants to join the first network after leaving the first network, the node can rejoin the first network only through authentication.

For another example, the master node can create an account, and the user can join the first network by logging in the account on a node to bind and authenticate with the master node.

It should be noted that after step 602, if there are other nodes that need to join the first network, they can join the first network through step 603, and if there are no other nodes that need to join the first network, then step 603 does not need to be executed.

604. At least one node in the first network (assumed to be N nodes, where N is an integer greater than 0) reports information about network functions supported by each to the master node. Correspondingly, the master node receives information about network functions supported by each of the N nodes.

When step 604 is implemented specifically, the N nodes may be all nodes in the first network except the master node, or may be some nodes in the first network except the master node. In FIG. 6 , it is drawn by taking N nodes as all nodes in the first network except the master node (that is, the N nodes are node a, node b and node d). It can be understood that all the N nodes are non-master nodes in the first network.

In specific implementation of step 604, for any non-master node, the non-master node may actively report the information of supported network functions to the master node, or may report the information of supported network functions based on the instructions of the master node. If it is the latter, the method further includes: the master node sends first indication information to the non-master node, where the first indication information is used to instruct to report information about supported network functions. The non-master node receives the first indication information from the master node, and reports the supported network function information to the master node under the instruction of the first indication information. It should be noted that, in actual implementation, all the nodes in the N nodes may report the information of supported network functions to the master node actively or based on the instruction of the master node, or some of the nodes in the N nodes may actively report to the master node. The nodes report the information of the supported network functions, and the other part of the nodes report the information of the supported network functions based on the instruction of the master node.

Among them, a node can support one or more network functions. A node can report information about all network functions it supports to the master node, and can also report information about some network functions it supports to the master node, which is not limited in this application.

Optionally, the information about a network function (assumed to be network function 1) supported by a node includes one or more of the following information: the identifier of the node, the name of the network function 1 supported by the node, the The identification of the network function 1, the power consumption of the network function 1 supported by the node, the execution strategy of the network function 1 supported by the node, whether the node supports proxying the network function 1, whether the node supports the master node to control the network Execution strategy for function 1. In addition to these information, the information about the network function 1 supported by a node may also include other information, which is not limited in this application.

Wherein, the identifier of the node may be, for example, a medium access control (medium access control, MAC) address of the node, an Internet protocol (internet protocol, IP) address of the node, a port number (port) of the node, a device name of the node, or Other information that can uniquely identify a node in the first network. The identifier of the network function is used to identify the network function. If a node supports a proxy for a network function, the node can perform the network function instead of the master node. If a node supports the execution strategy of the master node controlling the network function, the master node can send the execution strategy of the network function to the node, and the node can execute the network function according to the execution strategy sent by the master node. Among them, a node supports the master node to control the execution strategy of the network function, which means: the node supports the master node to formulate or modify or manage the execution strategy, the node only executes the execution strategy, and the node does not manage the execution strategy permission.

Among them, the power consumption of the network function, the execution strategy of the network function, whether to support the proxy network function, whether to support the execution strategy of the master node to control the network function and other information can be considered as the service attributes of the network function, and these information can belong to the same service attribute. Can also belong to a different service attribute. It should be noted that in addition to these information, the service attributes may also include other information, which is not limited in this application. Moreover, the information included in the service attributes of different network functions may be different or the same.

Exemplarily, taking node 1 as an example, information about the network function 1 supported by node 1 can be seen in FIG. 7 , which specifically includes the following information:

Name of network function 1: XXX (for example, network access management function)

Identification of network function 1: XXX (for example, 0002)

Identity of node 1: XXX (eg, MAC address of node 1)

Service attribute 1

Execution policy for network function 1: XXX

Power consumption of network function 1: XXX (for example, 1 milliamp (1mAh) per hour)

Service attribute 2

Whether to support proxy network function 1: XXX (for example, yes)

Whether to support the master node to control the execution policy of network function 1: XXX (for example, yes)

...

Service attribute N

...

Exemplarily, if the network function 1 supported by node 1 is the heartbeat function, the information of the heartbeat function can be referred to in FIG. 8 , which specifically includes the following information:

The name of the network function: heartbeat function

Identification of network functions: 0001

Node ID: MAC address of node 1

Service attribute 1

Heartbeat cycle range: 100 milliseconds (ms), 500 milliseconds, 1 second (s), 5 seconds, 10 seconds, 30 seconds

Heartbeat window time: 100 milliseconds

Power consumption during local heartbeat: 1 milliampere (1mAh) per hour

Service attribute 2

Whether to support proxying the network function: yes

Whether to support the master node to control the execution strategy of the network function: yes

...

Service attribute N

...

Among them, the value in the range of the heartbeat period shown in Figure 8 refers to the heartbeat period, that is, how long it takes to perform a heartbeat with other nodes except the master node, and the heartbeat window time refers to the time range for performing a heartbeat within a heartbeat period , the power consumption during the local heartbeat refers to the power consumption corresponding to a heartbeat window time.

Optionally, after the master node is determined, the master node sends the information of the master node to other nodes in the first network. Among them, the information of the master node can include information such as the identity of the master node and the connection mode supported by the master node. The identifier determines whether the received information is information sent by the master node.

605. The master node determines the auxiliary node among the M nodes (denoted as the th An auxiliary node, assumed as node d) in FIG. 6 , the first auxiliary node is used to replace the main node to perform the first network function.

Wherein, the M nodes may be part or all of the above N nodes. In FIG. 6 , it is drawn by taking the M nodes as all the above-mentioned N nodes (that is, the M nodes are node a, node b, and node d) as an example. The first network function is a network topology management function, a network access management function, a network device information management function or a heartbeat function, and may also be other network functions. It should be noted that the first network function is a network function that can be delegated to the master node. The network function that the master node can delegate can be preset in the master node, or it can be the master node according to some principles (for example, related to user security). Strongly related network functions cannot be delegated) determined.

It should be noted that if the master node cannot determine the first auxiliary node according to the information of the network functions supported by the M nodes and the information of the first network function of the master node, the master node executes the first network function by itself. The situation that the first auxiliary node cannot be determined may be that there is no node meeting the requirements among the M nodes. That is to say, the master node can determine whether there is a node among the M nodes that can act as a proxy for the first network function according to the information of the network functions supported by the M nodes and the information of the first network function of the master node, and if so, perform step 605 Subsequent steps, if not, the master node executes the first network function by itself.

Optionally, considering that the power consumption of the master node is too high, the first auxiliary node may be a constant power supply node among the M nodes that supports the first network function (for example, if the first network function is a network access management function, then The first auxiliary node can be a router or other devices with network access capabilities. For example, if the first network function is the heartbeat function, due to the constant power supply of the large screen, the main node can delegate the heartbeat function to the large screen for implementation. ); and/or, the first auxiliary node may be a node whose power consumption when performing the first network function is less than or equal to the power consumption when the main node performs the first network function. Wherein, the constant power supply node refers to a node that is powered by connecting an AC point through a power plug. An extraordinary power supply node refers to a node that is powered by devices such as batteries and charging treasures.

In the specific implementation of step 605, the master node may select a node among the M nodes that supports the first network function and meets one or more of the following conditions as the first auxiliary node: 1) supporting the execution of the first network function instead of the master node ; 2) Constant power supply; 3) The power consumption when executing the first network function is less than or equal to the power consumption when the master node executes the first network function; 4) Support the execution strategy of the master node to control the first network function; 5) Execute the first network function The delay when performing a network function is less than or equal to the delay when the master node executes the first network function; 6) the reliability when executing the first network function is higher than or equal to the reliability when the master node executes the first network function. In actual implementation, if multiple nodes can meet one or more of these conditions, the node that meets more of these conditions can be determined as the first auxiliary node, or a specific node that meets these conditions can be selected as the first auxiliary node. The conditional node is determined as the first auxiliary node, and the specific condition may be preset according to network requirements.

Wherein, when the delay when the first auxiliary node performs the first network function is smaller than the delay when the master node performs the first network function, the timeliness of the first network can be improved, and when the first auxiliary node performs the first network function The reliability is higher than the reliability when the master node performs the first network function, which can improve the reliability of the first network.

Exemplarily, taking the heartbeat function shown in FIG. 8 as an example, after receiving the information of the heartbeat function of a certain node, the master node will compare the information of the heartbeat function with the information of the local heartbeat function of the master node. Assuming that a heartbeat cycle is selected to be 500ms, the average power consumption of heartbeat execution on a certain node is:

That is to say, when the heartbeat period is 500ms, the maximum delay for the node to perceive other nodes except the master node is 500ms, and the average power consumption generated at the same time is 0.2mAh. The master node can also calculate the average power consumption of heartbeat execution on the master node when the heartbeat period is 500ms according to the information of its own heartbeat function. The master node compares the two, and if the average power consumption of a certain node is smaller, it can be judged that the node can be used as the first auxiliary node, but whether the node needs to be the first auxiliary node in the end still needs to be obtained according to the calculation The average power consumption of other nodes or other information of other nodes can be judged comprehensively. It should be noted that the average power consumption of performing heartbeat is used as an example for description here, and in actual implementation, direct comparison can also be made according to the power consumption during the local heartbeat period, which is not limited in this application.

It should be noted that, for the convenience of description in this application, the method provided in this application is described by taking the first assistant node acting as an example of the first network function as an example. For other network functions, only the first network function needs to be replaced by Other network functions can be understood. In addition to acting as the agent of the first network function, the first assistant node may also act as agent of other network functions at the same time.

Exemplarily, if the first network function is a network topology management function, the first auxiliary node may maintain network topology information instead of the main node. If the first network function is a network access management function, the first auxiliary node may perform network access instead of the main node. If the first network function is a network device information management function, the first auxiliary node may maintain the network device information instead of the master node. If the first network function is a heartbeat function, the first auxiliary node may replace the master node to perform heartbeat communication with other nodes, thereby maintaining synchronization of network information.

It should be noted that, in the embodiment of the present application, the network function of the assistant node agent is part of the network functions of the master node.

606. The master node sends first configuration information to the first assistant node, where the first configuration information is used to configure an execution policy of the first network function and/or a network information reporting manner of the first assistant node. Correspondingly, the first auxiliary node receives the first configuration information sent by the master node.

Optionally, the first configuration information includes first indication information and/or second indication information, the first indication information is used to indicate the network information reporting method of the first auxiliary node, and the network information reporting method is that the first auxiliary node reports to the master node Or the way that the second auxiliary node reports the network information related to the first network function, the second auxiliary node is used to report the network information related to the first network function reported by the first auxiliary node to the master node, and the second indication information is used Network function parameters when instructing the first auxiliary node to perform the first network function with other nodes, where other nodes refer to some or all of the M nodes except the first auxiliary node, assuming Q node.

Among them, Q nodes have communication interaction with the first assistant node. For example, through the heartbeat interaction, the heartbeat may adopt a connection mode (that is, perform heartbeat interaction through a wired connection), or a connectionless mode (that is, perform heartbeat interaction through a wireless connection), such as periodic broadcasting. In addition, after the master node determines the first assistant node acting as the agent for the first network function, the Q nodes have communication interaction with the first assistant node, and before the master node determines the first assistant node, for any of the Q nodes The node may or may not have communication interaction with the first auxiliary node.

Optionally, the network information reporting method includes reporting to the master node within the first preset time period when the network information changes, reporting to the master node according to the heartbeat cycle (that is, periodic heartbeat synchronization), reporting to the master node when Wifi or Bluetooth is connected, It may also include other methods (for example, active query by the master node, subscription by the master node), which are not limited in this application. By reporting the network information, the master node can obtain the network information of the first network, for example, obtain the real-time status of the overall network or the real-time status of some specified nodes in the network.

For more clarity, the communication methods of periodic heartbeat synchronization between the primary node and the secondary node (denoted as mode 1), active query of the primary node (denoted as mode 2) and subscription of the primary node (denoted as mode 3) are respectively carried out below introduce.

Mode 1. Periodic heartbeat synchronization.

In mode 1, the auxiliary node at least acts as the proxy for the heartbeat function, and the primary node and the auxiliary node will be periodically synchronized according to the execution policy of the heartbeat function. The heartbeat strategy here includes heartbeat period, heartbeat mode (for example, BLE or WiFi), etc., and the heartbeat strategy can be determined by the master node. On the auxiliary node, at least two sets of heartbeat strategies will be run. The first set of strategies is for the primary node, and the second set of strategies is for some or all nodes other than the primary node (for example, routing nodes, end nodes, etc.) of. In the second set of strategies, the auxiliary node needs to complete a heartbeat interaction with some or all nodes in the first network except the main node in each heartbeat cycle (assumed to be the first heartbeat cycle), so as to determine the first network Network information in . In the first set of strategies, the secondary node reports network information to the primary node every heartbeat period (assumed to be the second heartbeat period). The second heartbeat period may be an integer multiple of the first heartbeat period, or a heartbeat period greater than or equal to or less than the first heartbeat period, so as to achieve the purpose of reducing power consumption of the master node. The two sets of heartbeat strategies can be decided by the master node according to the actual situation of the network.

It should be noted that after the master node delegates the heartbeat function, on the one hand, the master node only needs to perform heartbeat interactions with the auxiliary nodes, and does not need to perform heartbeat interactions with a large number of nodes. Therefore, the workload of the master node can be greatly reduced. power consumption. On the other hand, if the second heartbeat period is longer than the first heartbeat period, the frequency of interaction between the master node and the assistant node is reduced, which can further reduce the power consumption of the master node.

Method 2. The master node actively queries.

In mode 2, the primary node actively queries the information in the secondary node, and the secondary node provides feedback. The query action can be initiated by the primary node at any time, and the secondary node needs to quickly feed back the information queried by the primary node (for example, current node information) in real time.

Method 3. The master node subscribes.

In mode 3, the primary node subscribes to the network information in the secondary node. For example, sometimes the main node pays more attention to the node information of some nodes in the first network. For example, the mobile phone (ie, the main node) may pay attention to the real-time network status of the tablet. Monitor the network status of the tablet. If the network status of the tablet changes, you can follow the strategy issued by the mobile phone to wake up the mobile phone in real time or according to the heartbeat cycle to synchronize the network status of the tablet. At this time, the mobile phone can know the real-time network status of the surrounding nodes without being frequently woken up, so as to reduce the power consumption of the mobile phone and maintain the consistency of the network status of the nodes in the first network. For another example, in the network topology management function, the master node can subscribe to the online and offline status of a certain type of equipment in the network topology information, so as to obtain the status of nodes joining and leaving the network in real time. The subscription function can be implemented by the primary node by configuring or updating the attributes of the service information to the secondary node.

It should be noted that there may be multiple types of network information related to the first network function, and the network information reporting methods corresponding to different network information may be the same or different, which is not limited in this application. For example, if the first network function is a network device information management function, the network information related to the first network function includes node information, node status information, node service information, and the like. Among them, the network information reporting method corresponding to the node information can be to report the master node within the first preset time period when there is a change, the network information reporting method corresponding to the node status information can be to report the master node according to the heartbeat cycle, and the service information of the node The corresponding network information reporting method may be to report to the master node when Wifi or Bluetooth connection.

Wherein, different network functions can be represented by different auxiliary nodes. For example, where a first auxiliary node proxies a first network function, other network functions may be proxied by other auxiliary nodes, eg by a second auxiliary node. If the first auxiliary node reports network information related to the first network function to the second auxiliary node, in the case where the first network function is a network access management function, the second auxiliary node may be a node that acts as a proxy for the network topology management function , at this time, if the heartbeat function is proxied by other nodes, the second auxiliary node can report the network information related to the first network function to the primary node through the auxiliary node proxying the heartbeat function. If the heartbeat function is not proxied by other nodes or the second The auxiliary node acts as a proxy for network topology management and heartbeat functions at the same time. The second auxiliary node can directly report network information related to the first network function to the primary node. If the first auxiliary node at least acts as a proxy for network access management and heartbeat functions, then Secondary node does not exist. In the case where the first network function is the network topology management function, if the heartbeat function is proxied by other nodes, the second auxiliary node can be a node that acts as a proxy for the heartbeat function. If the heartbeat function is not proxied by other nodes or the first auxiliary node is simultaneously proxied Heartbeat function and network topology management function, the second auxiliary node does not exist. In the case where the first network function is a network device information management function, it is similar to the case where the first network function is a network topology management function, which can be understood by referring to it. In the case where the first network function is the heartbeat function, the second auxiliary node does not exist.

Optionally, the network function parameter includes one or more of the following information: the name of the first network function, the identifier of the first network function, whether the first network function is proxied, the address of the node that proxies the first network function (ie The address of the first assistant node), the execution policy when the first network function is proxied, and the power consumption when the first network function is proxied.

Exemplarily, assuming that the first auxiliary node is node 1, and the first auxiliary node acts as an agent for the heartbeat function and the network device information management function, an example of the first configuration information can be seen in FIG. 9 , which specifically includes the following information:

The name of the network function: heartbeat function

Identification of network functions: 0001

Node ID: MAC address of node 1

Service attribute 1

Heartbeat cycle range: 500 milliseconds (ms)

Heartbeat window time: 100 milliseconds

Power consumption during local heartbeat: 1 milliampere (1mAh) per hour

Service attribute 2

Whether to proxy the network function: yes

Service attribute 3:

When the status of a node supporting XX capability changes, immediately report to the master node

(For example, when the screen resolution of a node that supports screen projection capabilities changes, immediately report to the master node)

When the service information of a device supporting XX capability changes, it will be synchronized to the master node according to the heartbeat cycle

(For example, when the attribute information of the service of the node supporting the gallery capability changes, it is synchronized to the master node according to the heartbeat cycle)

When the data of a node that supports XX capabilities changes, it is only synchronized when it is connected to WiFi

(For example, when the data of the service of the node supporting the gallery capability changes, it is only synchronized to the master node when the WiFi connection is connected)

...

Service attribute N

...

Wherein, service attribute 1 and service attribute 2 in FIG. 9 are network function parameters, and service attribute 3 is a network information reporting method. Specifically, the service attribute 1 is the execution strategy when the heartbeat function is proxied, and the service attribute 2 is the information whether the heartbeat function is proxied by node 1.

607. The master node sends second configuration information to the first node, the second configuration information includes third indication information and/or fourth indication information, the third indication information is used to indicate that the first network function is proxied by the first auxiliary node, and the second The four indication information is used to indicate network function parameters when the first network function is executed between the first node and the first auxiliary node, and the first node is a node among the Q nodes. Correspondingly, the first node receives second configuration information from the master node.

It should be noted that, in actual implementation, the master node may send second configuration information to each of the Q nodes for configuring network function parameters when performing the first network function between the corresponding node and the first assistant node In this application, the master node sends the second configuration information to the first node as an example for description, and the process of the master node sending the second configuration information to other nodes can refer to the first node, and will not be repeated here. Wherein, in FIG. 6 , the master node sends the second configuration information to each of the Q nodes (that is, to node a and node b) as an example for drawing.

Wherein, the above-mentioned first configuration information and second configuration information are deployment information of the first network function. For the description of network function parameters, please refer to the above. After each node receives the network function parameters, it can determine whether the first network function is proxied according to the information of whether the first network function is proxied. According to the address of the node that proxies the first network function Whether it is its own address determines whether it is the first auxiliary node, and determines the execution cycle of the first network function according to the execution cycle of the first network function when it is proxied (for example, if the first network function is a heartbeat function, it can be based on the cycle Determine the period for reporting network information, if you are the first auxiliary node, report to the master node, if you are not the first auxiliary node, report to the first auxiliary node).

It should be noted that, the types of network function parameters in the network function parameters sent by the master node to the first auxiliary node and in the network function parameters sent to the first node may be the same or different. The value of the same network function parameter sent by the master node to the first assistant node and sent to the first node may be the same or different, which is not limited in this application.

Exemplarily, taking the first network function as the heartbeat function as an example, an example of the second configuration information sent by the master node to the first node can be seen in FIG. 10 , which specifically includes the following information:

The name of the network function: heartbeat function

Identification of network functions: 0001

Node ID: MAC address of node 1

Service attribute 1

Heartbeat cycle range: 500 milliseconds (ms)

Heartbeat window time: 100 milliseconds

Power consumption during local heartbeat: 1 milliampere (1mAh) per hour

Service attribute 2

Whether to proxy the network function: Yes

...

Service attribute N

...

Optionally, the second configuration information also includes fifth indication information, the fifth indication information is used to indicate the network information reporting method of the first node, and the network information reporting method of the first node is that the first node reports to the first auxiliary node A mode of network information related to the first network function. At this time, an example of the second configuration information sent by the master node to the first node can be seen in FIG. 9 , the only difference is that the master node in service attribute 3 is replaced by the first assistant node. For other descriptions of the network information reporting method, refer to the above, and will not repeat them here.

It should be noted that, if the second configuration information does not include the fifth indication information, the first node may report the network information by using a certain network information reporting manner by default.

It should be noted that the execution sequence between step 606 and step 607 is not in any order.

608. The first auxiliary node executes the first network function according to the execution policy of the first network function, and/or, the first auxiliary node reports the network information according to the network information reporting mode of the first auxiliary node.

Optionally, if the first configuration information includes the first indication information and/or the second indication information, the first auxiliary node reports the network information related to the first network function to the master node according to the network information reporting method indicated by the first indication information. information, and/or, the first assistant node executes the first network function with other nodes according to the network function parameters indicated by the second indication information.

When reporting network information, specifically, the first auxiliary node receives network information related to the first network function from Q nodes, and reports the network information related to the first auxiliary node to the main node or the second auxiliary node according to the network information reporting method of the first auxiliary node. - Network information related to network functions.

In specific implementation of step 608, after receiving the first configuration information sent by the master node, the first assistant node can start acting as a proxy for the first network function.

It can be understood that in this application, it is not necessary for the master node to uniformly manage the overall network as in the prior art (at this time, the master node needs to obtain the entire network information with a relatively high heartbeat cycle), and the assistant node interacts with other nodes to obtain Network information, while the master node only needs to obtain network information from the auxiliary node, so the power consumption of the master node can be reduced.

609. The first node determines the first assistant node according to the third indication information, and/or, the first node performs the first network function with the first assistant node according to the network function parameter indicated by the fourth indication information.

Exemplarily, if the network information reporting method of the first node is periodic heartbeat synchronization, the first auxiliary node may maintain network information in a heartbeat manner. Taking the example shown in FIG. 10 , if the network information changes, the first node may use a heartbeat period of 500 ms to perform heartbeat with the first auxiliary node, thereby synchronizing the network information. The first auxiliary node may also maintain network information through lease management. For example, the first node may communicate with the first auxiliary node during the lease to synchronize network information and/or network topology information.

It should be noted that, if the master node sends the second configuration information to each of the Q nodes, each of the Q nodes can be configured according to the difference between the network function parameters indicated by the fourth indication information and the first auxiliary node. Execute the first network function between each node in FIG. 6 by taking the execution of the first network function between each of the Q nodes (that is, node a and node b) and the first auxiliary node as an example.

It should be noted that the execution sequence between step 608 and step 609 is not in any order.

610. If the network function parameter changes, the primary node sends third configuration information to the first secondary node, and sends fourth configuration information to the first node. Wherein, the third configuration information is used to update the network function parameters when the first network function is executed between the first auxiliary node and Q nodes, and the fourth configuration information is used to update the first network function parameters executed between the first auxiliary node and the first auxiliary nodes. The network function parameter when the network function is used. Correspondingly, the first auxiliary node receives third configuration information from the master node, and the first node receives fourth configuration information from the master node.

It should be noted that, the master node may send fourth configuration information to each of the Q nodes, for updating network function parameters when the first network function is executed between the corresponding node and the first assistant node. FIG. 6 is drawn by taking the master node sending fourth configuration information to each of the Q nodes (that is, node a and node b) as an example.

After step 610, the first assistant node and/or the first node may feed back an update status to the master node, where the update status is used to indicate whether the network function parameter is successfully updated.

611. The first assistant node performs the first network function with the first node according to the updated network function parameter. If each of the Q nodes has received the fourth configuration information, the first assistant node may perform the first network function with the Q nodes according to the updated network function parameters. FIG. 6 is drawn by taking the master node executing the first network function with each of the Q nodes (ie, node a and node b) according to the updated network function parameters as an example.

Optionally, if the updated network function parameters between the first auxiliary node and Q nodes when performing the first network function indicate that the first auxiliary node no longer acts as the agent for the first network function (for example, the node acting for the first network function The address of the primary node is changed to empty or the address of the primary node), the method further includes: the first secondary node determines that it will no longer act as a proxy for the first network function.

Optionally, if the primary node determines not to use the first secondary node to act as a proxy for the first network function (for example, when the first secondary node leaves the first network, or the quality of communication between the primary node and the first secondary node deteriorates, etc. In this case, the master node may determine not to use the first assistant node to act as the proxy for the first network function), the method further includes: performing the first network function between the master node and other nodes in the first network; or, the master node re-assigns The first network function selects an auxiliary node, and the first network function is executed between the re-selected auxiliary node and Q nodes. At this time, the first network function is executed between the first node and the auxiliary nodes re-selected by the master node.

It should be noted that the master node controls the function of the first assistant node mainly by updating network function parameters when the first assistant node executes the first network function. The primary node can first send a command to the first secondary node to ask the first secondary node to update the network function parameters (for example, heartbeat period) of the first network function it proxies. After the first secondary node performs the update operation, it will reply to the primary node The update status of the network function parameter of the first network function of the node, such as success or failure. If the network function parameters of the first network function are successfully updated, this update operation is completed. Otherwise, the primary node will implement the failure protection strategy based on the update failure information of the first secondary node, including update retry, or forcibly withdraw the proxy capability of the first secondary node, and at the same time, relevant information (for example, the first secondary node will no longer execute The information of the first network function) is synchronized to other common nodes in the network (such as routing nodes, end nodes, etc.). At the same time, other nodes in the network, after receiving the synchronization message from the master node, stop performing the first network function with the first auxiliary node, and switch to execute the first network function with the master node or other auxiliary nodes designated by the master node. 1. Network function.

It should be noted that the information that the first auxiliary node no longer performs the first network function may be indicated to each node through the updated network function parameters of the first network function, or may be indicated to each node by the master node alone. Applications are not restricted. If it is the latter, the interaction between the first auxiliary node and the master node includes: the master node sends an indication message (denoted as the sixth indication information) to the first auxiliary node and the first node, and the sixth indication information is used to indicate that the first auxiliary node An auxiliary node stops acting for the first network function; the first auxiliary node and the first node reply feedback information to the main node, and the feedback information is used to notify whether to acquire information that the first auxiliary node stops acting for the first network function. It should be noted that the indication information is a mandatory command, that is to say, after the master node sends out the indication information, the master node considers that the first auxiliary node no longer acts as the agent of the first network function. It is an optional process for the first assistant node to reply the feedback information.

After the first auxiliary node receives the stop proxy service command sent by the master node (the above-mentioned sixth indication information or the updated network function parameter of the first network function indicating that the first auxiliary node no longer acts as an agent of the first network function), the first The secondary node stops proxying the first network function, and releases data during the proxy task execution. It should be added here that when the first auxiliary node stops acting as a proxy for the first network function, whether the data maintained by it and the data maintained by the master node are consistent and synchronized is determined by the parameters in the stop proxy service command issued by the master node. Generally, whether these data are consistent and synchronized is determined by the consistency requirements of the network functions proxied by the first auxiliary node, and the consistency requirements of different network functions will be different. For example, if the proxy network topology management function, in order to avoid new network managers (for example, new auxiliary nodes proxying the network topology management function) to collect network topology information and reduce the impact on the first network, it will require the first The auxiliary node performs consistent synchronization of network topology information. For another example, if the first auxiliary node acts as a proxy for the heartbeat function, and the primary node selects a new secondary node to act as the agent for the heartbeat function, it is not necessary to perform consistent synchronization at this time, and the primary node and the new secondary node can perform consistent synchronization.

It should be noted that the master node may not update the network function parameters, therefore, step 610 and step 611 may not be executed.

It should be noted that, in addition to the master node deciding not to let the first auxiliary node act as the agent of the first network function, the first auxiliary node may also leave the first network. At this time, the master node can perform the first network function by itself, or The secondary node is re-elected to perform the first network function.

612. The master node leaves the first network.

After step 612, the first network is released. It should be noted that the master node may not leave the network, therefore, step 612 may not be executed. It should be noted that step 612 may be performed after any of the above steps, depending on the behavior of the master node.

Optionally, after the master node determines the first auxiliary node, the first auxiliary node can communicate with the master node about the maximum offline duration of the master node, such as 1 day, or 1 week. When the auxiliary node completes any interaction, the first auxiliary node will think that the primary node of the first network has left the first network, and the first network will be released. In the subsequent process, the first auxiliary node can negotiate with other nodes that have established connections to re-select the primary node, and the primary node can re-select the secondary node.

Exemplarily, the maximum offline duration may be configured by the primary node to the first secondary node in the first configuration information. If there are multiple auxiliary nodes, the maximum offline duration configured by the master node for different auxiliary nodes can be the same or different, which is not limited in this application. In one case, when the master node does not complete any interaction with the slave node within the maximum offline duration corresponding to the slave node, it is considered that the master node has left the first network. In another case, when the master node does not complete any interaction with multiple auxiliary nodes within the maximum offline duration corresponding to multiple auxiliary nodes (which may be some or all of the auxiliary nodes), it is considered that the main node has left the first network.

It should be noted that if the master node leaves the first network for less than the maximum offline duration, each auxiliary node will continue to perform the network function of its own agent during the master node's departure. Do it later. That is to say, the method provided by this application can meet the mobility requirements of the master node in the distributed network. Due to the introduction of the auxiliary node, the master node in the network can leave the network for a period of time without affecting the network operation, that is, without It will affect the steady state of the network too much (that is, the steady state). Among them, the steady state refers to the stable state in which the data to be transmitted generated by one or more sending nodes in the network is transmitted through the medium in the network, reaches other one or more receiving nodes, and is received and processed. If the amount of data produced and transmitted by the sending node is greater than the amount of data received and processed by the receiving node, there will be network congestion. If the amount of data produced and transmitted by the sending node is less than or equal to the amount of data received and processed by the receiving node, the network is in a steady state. It should be noted that a network will have multiple steady states, but as long as a node leaves or enters the network, the current steady state will be destroyed, requiring the network to adaptively find and match the next steady state.

In order to meet the requirements of optimal network experience in various scenarios, this application can choose a relatively stable node in the network when selecting an auxiliary node. This node can monitor the steady state of the network, so that when other nodes enter or leave the network When , the auxiliary node can optimize the network status more specifically and provide better network delay and bandwidth guarantee.

The process shown in FIG. 6 briefly introduces the process of determining the auxiliary node by the master node and decentralizing the network function.

The method provided by this application realizes the semi-centralized management of the master node by handing over (or decentralizing) some of the network functions of the master node to the auxiliary nodes in a distributed network, thereby reducing the power consumption of the master node and improving Network timeliness and reliability.

Specifically, the network function of the master node is split, and the master node can designate other nodes to act as network functions according to the capabilities of other nodes in the network, and transfer one or more network functions that need to be processed by the master node to other nodes for execution. The network functions limited by the capabilities of the master node equipment can be transferred to other nodes in the network that can perform more optimized network functions. For example, transferring the network function (for example, heartbeat function) of the master node that is sensitive to power consumption to a node that is not sensitive to power consumption (for example, a large screen) can realize the perception of the master node with lower power consumption. And manage the overall network, so as to avoid frequent network changes (for example, nodes constantly join or leave the first network), achieve a balance between network power consumption and performance, and greatly improve the user coverage of the distributed network. For the heartbeat function, further, differentiated communication methods between the primary node and the secondary node can also be combined (for example, the heartbeat period between the primary node and the secondary node is greater than the heartbeat period between the secondary node and other nodes), thereby reducing the number of primary nodes. power consumption. For another example, bandwidth-sensitive network functions can be transferred to high-bandwidth nodes (such as routers, large screens, PCs, etc.) in the distributed network, thereby improving network transmission rate and reliability. It should be noted that if there is no suitable node in the network to act as a proxy for the network function, the master node still needs to perform the network function by itself.

It should be noted that the start, change and stop of the network function of the agent of the secondary node can only be decided by the primary node. Secondary nodes do not have the ability to ask non-primary nodes to switch to other nodes.

In order to make the embodiment of the present application more clear, the implementation process of the above method is illustrated below from the perspective of the first auxiliary node. In this example, it is assumed that the first auxiliary node joins the first network after the master node is determined, see FIG. 11 ,include:

1101. The first assistant node searches for a distributed network node (that is, a master node).

Before step 1101, the first auxiliary node can be initialized, so as to enable the network search function to perform network search.

1102. The first assistant node joins the first network by binding and authenticating with the searched master node.

1103. The first auxiliary node reports information about supported network functions to the master node, and acquires information about the master node.

Among them, the information of the primary node can be information such as the identity of the primary node, the connection mode supported by the primary node, etc. In the subsequent process, the first secondary node can communicate using the connection mode supported by both The identity of the node determines whether the received message is sent by the master node.

1104. The first auxiliary node receives first configuration information of the master node.

1105. The first assistant node determines that it acts as a proxy for the first network function according to the first configuration information, executes the first network function according to the execution policy of the first network function, and reports network information according to the network information reporting method of the first assistant node.

1106. If the network function parameters of the first network function change, the first auxiliary node receives third configuration information from the master node, where the third configuration information is used to update network function parameters when the first auxiliary node executes the first network function.

1107. The first assistant node executes the first network function according to the updated network function parameter.

1108. The first auxiliary node leaves the first network.

It should be noted that the first assistant node may not leave the first network, and in this case, step 1108 may not be performed.

In the case where the first assistant node acts as a proxy for the network access management function, take the first assistant node reporting network information related to the network access management function to the master node as an example. In the subsequent process, the first assistant node can actively broadcast search , the active broadcast search is mainly used to scan and discover other unnetworked nodes. When a new node joins, the new node can scan the active broadcast search of the first auxiliary node to obtain the information of the first auxiliary node and establish a connection with the first auxiliary node. The information that the new node joins (for example, the node’s identity) will be kept on the first auxiliary node first, and then fed back to the main node according to the heartbeat strategy of the main node, or, if the main node makes an active query, the first auxiliary node can quickly return Information about new node joining. In this case, the network access of the new node and the subsequent information processing flow can be seen in Figure 12, including:

1201. Node X searches for distributed network nodes.

Wherein, the searched distributed network node may be the primary node, or may be the first auxiliary node. If the searched distributed network node is the first auxiliary node, the first auxiliary node may be responsible for authentication, or for binding and authentication. In FIG. 12, description is made by taking node X searching for the first assistant node as an example.

When step 1201 is actually implemented, the first network will push the node that performs the network access management function to node X, and node X determines the node that performs network access based on this, but node X will not distinguish between nodes that perform the network access management function. Whether the node is primary or first secondary.

1202. Node X joins the first network through the searched distributed network nodes.

If the first auxiliary node is responsible for authentication, node X joins the first network through authentication; if the first auxiliary node is responsible for binding and authentication, node X joins the first network through binding and authentication.

1203. The first auxiliary node sends the information of the first auxiliary node and the information of the master node to node X.

In the subsequent process, if node X receives an instruction with contradictory functions sent by the master node and the first auxiliary node at the same time, it will execute according to the instruction of the master node.

1204. Node X sends the information that node X joins (for example, the identity of node X, the connection mode of node X, etc.) to the first assistant node.

1205. The first secondary node performs heartbeat communication with the primary node. The function of the heartbeat communication here is to determine whether the devices communicating with each other are online.

1206. The first auxiliary node sends the information that node X joins to the main node.

1207. Node X leaves the first network.

It should be noted that node X may not leave the first network, and in this case, step 1207 may not be performed.

Exemplarily, the composition of each node above can be seen in FIG. 13 , and the included modules may be different for different nodes, which is not limited in this application. The function of each module in Fig. 13 is as follows.

The device management module is used to manage the information of each node in the network that has been established (for example, the first network above), and is also used to process the binding and authentication of network-connected nodes and maintain node information in the overall network.

The network state management module is responsible for the synchronization and maintenance of the state information of each node in the network. For example, the active heartbeat scheme can be combined with the lease scheme to maintain the state information of each node.

The configuration management module is used to manage various configuration items and policy items of the network.

The routing management module is responsible for the construction and maintenance of information such as routing forwarding tables and routing tables. Among them, routing is divided into heterogeneous routing management according to the difference in forwarding type or routing data type (for example, 3 devices A, B, and C, A and B are connected through Bluetooth, B and C are connected through WiFi, A is connected through Bluetooth link Communication data to B that supports Wifi, and then B forwards it to other WiFi access devices C) and isomorphic routing management (for example, 3 devices A, B, and C are all connected through WiFi, and A can pass B The WiFI forwards and transmits the data to C).

The routing selection module is responsible for selecting the best network path for calculation by calculating the network path and time delay in the network.

The device address management module is responsible for the allocation and management of network device addresses.

The routing engine module, based on the abstract management of various low-level communication technologies, adopts the event state mechanism to manage the low-level specific implementation of physical communication media.

The lowest layer Bluetooth communication, basic WiFi communication, WiFi P2P communication, virtual wireless access point (WiFi SoftAP) communication, USB communication, etc. are packaged for various specific communication technology protocols. On the control plane, it will interact with the control protocol of the specific protocol , such as Bluetooth's generic access profile (GAP) protocol, WiFi's 802.11MAC protocol, and at the data level, it will also interact with specific protocol standards to achieve data interconnection, such as classic Bluetooth (that is, Bluetooth BR) The radio frequency communication protocol (radio frequency communication, RFCOMM) protocol, BLE attribute protocol (Attribute Protocol, ATT)/generic attribute profile (generic attribute profile, GATT), etc.

In this application, for the overall framework shown in Figure 13, differentiated deployments will be made on the primary node and secondary nodes. Specifically, the ability of the overall framework will be fully deployed on the master node, but differentiated deployment will be deployed on the auxiliary node, so that the auxiliary node has the ability to manage network information, but such capabilities can only be implemented according to the strategy required by the master node Execution, such as the heartbeat strategy, needs to be aligned with the clock of the master node. At this time, the master node can know the wake-up cycle of the overall network managed by the auxiliary node, but the master node can confirm that it can tick according to the clock, according to its own energy consumption strategy ( For example, two clock cycles, or a dynamic clock cycle) are used to interact with the auxiliary node to obtain real-time information maintained by the auxiliary node.

The physical devices involved in this application include but are not limited to WiFi, Bluetooth, USB, network card, central processing unit (central processing unit, CPU) in the node.
