Those of ordinary skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments without conflict.
The communication method of the distributed network node provided in the embodiment of the present application may be applied to an application environment shown in fig. 1, where fig. 1 is an application environment schematic diagram of the communication method of the distributed network node according to the embodiment of the present application.
As shown in fig. 1, a node 10 and a controller 11 are a communication device and a proxy server in a communication scenario, respectively, in which the node 10 registers its own node information with the controller 11, the controller 11 records and manages the node information, and provides an information inquiry service to other nodes. The controller 10 and a plurality of nodes 10 dispersed in each area together constitute a distributed communication network. In the communication network, the number of nodes may be many, but the controller 10 has only one public network controller and a number of temporary private network controllers. Further, after any node a queries the node information of the target node B through the controller 11, a direct connection channel can be established with the target node B according to the node information, and then communication can be performed without depending on the controller 11.
Further, the node 10 may be various portable mobile communication devices, such as wireless communication devices like mobile phones and tablet computers; or a fixed wired communication device such as a desktop computer and a fixed telephone. Further, the controller 11 may be a public network controller disposed in a public network, such as a communication base station; or a private network controller arranged in a private network environment. It should be noted that, the private network controller in this application is not implemented by an application-specific device (such as a router, a switch, etc.), but is used for managing node information registered by a node and providing an inquiry service, etc. by using the node in a private network environment to also serve as the private network controller.
Fig. 2 is a flowchart of a communication method of a distributed network node according to an embodiment of the present application, where the flowchart includes the following steps, as shown in fig. 2:
s201, when a node roams into a first private network, searching a private network controller in the first private network by sending a broadcast message, wherein the private network controller is dualized by the node in the first private network;
node roaming refers to a process in which a mobile communication device leaves its service area (registered area), enters a new area, and continues to be used in the new area.
For example, node a is a user's smartphone that initially registers as a public network node for area a and acquires and uploads data over the public network. After the user enters the coverage area of the local area network in the area B with the smartphone, the user obtains and uploads data through the internal network of the local area network, that is, a specific node roaming process.
In this embodiment, the first private network is an internal network of various hierarchies, which may be but not limited to a home local area network, a company intranet, or a WIFI network provided by a shop/campus. Further, the private network controller is configured to manage node information of each node in the first private network, and provide a node information query service to each node in the private network.
It should be noted that, in the present application, a private network controller does not need to be deployed in advance by using a special gateway device. The private network controller may be taken by any existing node within the first private network or a new node roaming in. Optionally, when selecting a node which doubles as a private network controller, a node device with good network conditions and high hardware performance is preferentially considered.
S202, after receiving a reply response sent by a private network controller, completing private network node information registration in the private network controller, wherein the private network node information comprises a node IP and a node port;
in step S201, the roaming node queries whether a private network controller exists in the first private network by sending a broadcast message, and correspondingly, in this step, when receiving a reply response from the private network controller, the roaming node indicates that a target has been queried, and may further execute a registration procedure.
When the node registers with the private network controller, the private network controller synchronously learns the node information. Further, the private network controller records the IP information and the port information corresponding to each node, and each node may send a request to the private network controller to query the IP information and the port information of other nodes.
It should be noted that the node applies some preset communication policies, thereby supporting automatic discovery of the private network server, and realizing registration of node information and node connection without user's own perception or manual configuration. Optionally, the preset communication policy applied by the node may be deployed in a mobile phone APP (Application) corresponding to the personal private cloud product.
S203, obtaining the private network node information registered by each node from the private network controller, establishing a private network channel between the nodes according to the private network node information, and communicating by using the network service in the first private network.
For example, after the node a roams into the first private network and completes its node information registration, if the existing node B in the current network needs to connect to the node a, it only needs to acquire the IP and port of the node a from the private network controller, and then it can establish a private network channel with the node a and perform communication. Meanwhile, if the node A needs to communicate with other nodes in the private network, the IP and the port of the node to be connected can be obtained through the private network controller, and a private network channel is established with other nodes for communication based on the IP and the port.
It should be noted that, in the first private network, the connection and communication process between the nodes directly utilizes the high-quality network conditions and mature network services in the first private network, and does not need to be forwarded by the public network controller, so that the stability and security of node communication can be improved.
Through the steps S201 to S203, compared with the method in the related art that the connection of the nodes in the private network needs to be realized through the public network controller, the private network controller is introduced in the embodiment of the present application, and the private network controller with the nodes being concurrently responsible for the registration and query of the node information in the private network. Through the private network controller, nodes in the private network can establish connection and communicate by applying network conditions under the private network without passing through a public network environment. The technical problem that the node communication method in the related technology is poor in reliability and safety is solved, and reliability and safety are improved.
In some embodiments, after the node sends the broadcast packet, if the private network controller is not found in the first private network, an election process of the private network controller is performed, where the election process is to determine, based on a preset rule, a target node that is most suitable as the private network controller among all nodes.
In some embodiments, fig. 3 is a flowchart of determining a private network controller according to an embodiment of the present application, and as shown in fig. 3, the flowchart specifically includes the following steps:
s301, determining a target node set composed of non-portable communication equipment in all nodes of a first private network;
due to the easy mobility of the portable communication device, the portable communication device may move out of the network coverage of the first private network, so when determining the target node, the non-portable communication device should be preferably excluded, and a target node set consisting of fixed communication devices should be acquired.
S302, in a target node set, obtaining expected values of all nodes according to bandwidth conditions and hardware performance of all nodes, wherein the expected values reflect matching degrees of the nodes serving as private network controllers;
further, it is considered that the node serving as the private network controller must have high stability, and at the same time, the node registration and query service requirements of most devices must be satisfied. Therefore, the bandwidth situation and the hardware performance of the node device need to be comprehensively considered in the election. Alternatively, an expected value may be calculated based on network bandwidth conditions, hardware performance, and other weights of the node devices, where the expected value reflects a matching degree of the node doubling as the private controller.
S303, selecting a node with the highest expected value as a target node.
And finally, selecting a node with the highest expected value, namely the most suitable node, as a target node, and enabling the target node to be used as a private network controller, so that the node information security and the node communication stability can be further improved.
In some embodiments, the communication between the node and the public network node is not affected while the communication between the node and the public network node is satisfied. After the node roams into a first private network, the node synchronously registers public network node information in a public network controller while registering the information in the private network controller, wherein the public network controller is deployed in a public network environment;
then, the public network node outside the first private network can obtain the public network node information registered by the node from the public network controller; and a public network channel can be established with the node in the first private network according to the public network node information, and communication is carried out by utilizing public network service.
Fig. 4 is a schematic diagram of a node communication method according to an embodiment of the present application, and as shown in fig. 4, a node 2 is a roaming node, a node 1 is a current node in a region 1, and a node 5 is a public network node in the region 5. In this embodiment, the process of implementing communication between the node and the private network while not affecting communication between the roaming node and the public network node includes the following steps:
step 1, when a node 2 outside the region 1 roams into the region 1 where the node 1 is located and is in the same private network as the node 1, the node 2 inquires whether a private network controller exists in the current private network or not by sending a broadcast message;
step 2, if the node 1 is also used as a private network controller, the node 1 replies to the node 2 after receiving the broadcast message sent by the node 2 and declares that the node is the private network controller; if the node 1 is not also used as a private network controller and the node 2 does not find the private network controller, the private network controller can be selected from the node 1 and the node 2 in a competition manner;
step 3, the node 1 and the node 2 register node information to the private network controller, and the private network controller learns the private network information of the nodes; in addition, the node 2 also synchronously registers node information to the public network controller;
step 4, when the node 1 needs to communicate with the node 2, the node 1 sends first requests to the private network controller and the public network controller respectively so as to obtain the information of the node 2; when the node 1 needs to communicate with the node 5, the node 1 sends a second request to the public network controller to acquire information of the node 5;
and 5: when the private network controller and the public network controller receive the first request, respectively replying the node 2 information to the node 1; when the public network controller receives the second request, the public network controller replies the information of the node 5 to the node 1;
step 6: the node 1 preferentially uses the private network information returned by the private network controller to establish a private network channel with the node 2 for communication; in addition, the node 1 establishes a public network channel with the node 5 and communicates with the node 5 by using the information of the node 5 returned by the public network controller.
In some embodiments, the communication with the private network nodes in other regions is not influenced while the communication of the nodes in the private network is satisfied. After the node completes the registration of the public network node information in the public network controller, the private network node located in the second private network can obtain the public network node information registered by the node from the public network controller; and then, according to the public network node information, a public network channel can be established with the node in the first private network, and communication is carried out by utilizing public network service.

As shown in fig. 5, the node 3 and the node 4 are nodes in the private network environment in the region 3, and the process of implementing the node communication across the private network includes the following steps:
step 1: the node 1 and the node 3 roam to different private networks of different regions respectively, and the two nodes need to communicate through a public network controller;
step 2: when the node 1 needs to communicate with the node 3, the information of the node 3 is requested to a controller of the private network 1 and a public network controller;
and step 3: the private network 1 controller can not return effective node 3 information, and the public network controller returns the public network information of the node 3;
and 4, step 4: and the node 1 receives the public network information of the node 3 returned by the public network controller, and establishes a public network channel with the node 3 for communication.
In some embodiments, the node performs connection and communication through a public network before roaming into the first private network. The method specifically comprises the following steps: and the node completes the public network node information registration in a public network controller, wherein the public network controller is deployed in a public network environment, and the node is also positioned in the public network environment. Further, the node acquires public network node information registered by each public network node from the public network controller, establishes a public network channel between the public network nodes according to the public network node information, and communicates by using public network services.

and 2, step: when the node 1 needs to communicate with the node 2 or the node 5, the node 1 requests public network information of the node 2 or the node 5 from a public network controller;
and step 3: after receiving the request, the public network controller replies the public network information of the node 2 or the node 5 to the node 1;
