Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.
With the rapid development of wireless Mesh network technology, more and more routers with Mesh functions enter the home. As the wireless router rate increases, its price decreases gradually; however, since the high transmission power of the wireless Mesh router may cause harm to the health of human body, the network coverage of the wireless router is gradually reduced. In a home application scenario, a home intranet may be built by multiple wireless routers to achieve coverage of a wireless network of a whole house.
However, if a certain wireless Mesh router fails, a plurality of devices connected with the wireless Mesh router network cannot obtain communication service, so that the stability of the Mesh network system is reduced.
Based on the above problems, the present application provides a network switching method, a node, an electronic device, and a readable storage medium, which can switch end-to-end communication connection between a master node and a slave node through a network, not only enable the slave node that generates a fault to directly communicate with the current master node, but also enable the slave node to continue to communicate with other nodes through the current master node, thereby reducing the possibility of network paralysis and improving the system stability of the communication network.
Fig. 1 shows a flow chart of a network switching method according to an embodiment of the present application. The network switching method can be applied to a network switching master node. As shown in fig. 1, the network handover method in the embodiment of the present application includes, but is not limited to, the following steps.
Step S101, when it is determined that the child node fails according to the network status information of the child node, a first handover message is generated.
Step S102, a first switching message is sent to the sub-node for the sub-node to switch its network connection mode to a network connection mode supporting end-to-end communication.
In the embodiment, the network state information of each sub-node is acquired, so that the network state condition of each sub-node can be monitored, and the network management of each sub-node is facilitated; under the condition that the child node is determined to be faulty according to the network state information of the child node, a first switching message is generated, the faulty child node can be processed in time, and the fault proportion that other nodes cannot communicate due to the fact that the factor node is faulty is reduced; and sending a first switching message to the child node so that the child node switches the network connection mode into a network connection mode supporting end-to-end communication, and through the end-to-end communication connection with the child node, not only can the child node with faults directly communicate with the current main node, but also the child node can continuously communicate with other nodes through the current main node, thereby reducing the possibility of network paralysis and improving the system stability of the communication network.
It should be noted that, the network switching master node may be a node supporting a connection mode of a Mesh network (Mesh network), and simultaneously support end-to-end communication (e.g., a node supporting an end-to-end action hotspot (WiFi-Peer, wiFi-P2P)). The network handover master node may also be a node that supports legacy communications (e.g., mobile communications) and supports end-to-end communications. The above communication modes of the network switching master node are only exemplified, and can be specifically set according to actual needs, and other communication modes of the network switching master node which are not explained are also within the protection scope of the present application, and are not described herein.
For example, fig. 2 shows a schematic structural diagram of a network switching system according to an embodiment of the present application. As shown in fig. 2, the Mesh network master node 220 may include a Mesh network assistant 221, which constructs a Mesh network 210 with a plurality of child nodes (not shown in the figure), and a WiFi-P2P network 230, respectively.
The child nodes in the Mesh network 210 may also be child nodes in the WiFi-P2P network 230, that is, the child nodes connected to the Mesh network master node 220 can support two different communication modes at the same time.
It should be noted that, in the Mesh network 210, through dynamic self-organization and self-configuration, the installation overhead of multiple child nodes can be reduced, and the operation cost is reduced. The ability of child nodes to self-configure may enable dynamic allocation of workload. And WiFi-P2P is an end-to-end communication technology among WiFi technologies, and two or more devices are connected through an end-to-end communication technology to form a small-range communication network. In a WiFi-P2P network, one Group Owner device (GO) and multiple Group Clients (GC) may be included.
The Mesh network assistant 221 is configured to collect network state information of each sub-node in the Mesh network 210, monitor communication states of different sub-nodes based on the network state information of each sub-node, and detect possible faults of each sub-node in real time, and process each sub-node in time, so as to improve safety of the Mesh network.
For example, after the Mesh network master node 220 gathers the network state information of each sub-node in the Mesh network 210 through the Mesh network assistant 221, the network state information of these sub-nodes and the current communication network connection mode corresponding to the sub-nodes may be stored in the database, so as to facilitate subsequent query or update.
In some specific implementations, the Mesh network master node 220 may further perform a "ping" operation on each child node through the Mesh network assistant 221 at intervals of a preset duration (for example, 5 seconds or 10 seconds, etc.), so as to obtain a network connection state of each child node. For example, when a "ping" operation is performed on a certain child node, if the time delay fed back by the child node is smaller than a preset time delay threshold (for example, 20ms, etc.), it is indicated that the child node is connected to the Mesh network master node 220; otherwise, it is characterized that the child node is not connected to the Mesh network master node 220.
The network switching master node 220 may be a Mesh wireless router, or may be a terminal (for example, a smart phone or the like) supporting different communication modes. The above types of the network switching master node are only illustrative, and can be specifically set according to actual needs, and the network switching master node and the sub-node establishing communication connection with the network switching master node can support at least two different functions of network communication connection.
The network switching master node 220 can be provided with collection of network state information of each child node in the Mesh network; the state of each child node can be monitored; and under the condition that a certain sub-node is determined to have communication failure, the communication connection mode between the network switching main node 220 and the sub-node is switched to a network connection mode supporting end-to-end communication, so that the sub-node can continue to communicate with other nodes, and the communication efficiency is improved.
In this embodiment, the network state information of each sub-node in the Mesh network can be monitored by the network switching master node 220, so that a sub-node with a communication failure can be found in time, and further, an end-to-end communication mode is established between the network switching master node 220 and the failed sub-node, the GO or GC of the WiFi-P2P network can be fused into the Mesh network, the communication stability of each sub-node in the Mesh network is ensured, and the use experience of a user on the wireless Mesh network can be improved.
Fig. 3 is a flow chart illustrating a network switching method according to an embodiment of the present application. The network switching method can be applied to a network switching master node. As shown in fig. 3, the network handover method in the embodiment of the present application includes, but is not limited to, the following steps.
Step S301 establishes a first communication connection with a plurality of child nodes based on a connection mode of the mesh network.
The connection mode of the mesh network may include: a connection mode of a mobile Ad Hoc network, and/or a connection mode of a Mesh network.
By establishing the first communication connection with the plurality of child nodes, the network switching master node can communicate with the plurality of child nodes based on the first communication connection, and acquire communication information of the plurality of child nodes.
Step S302, establishing a second communication connection with the plurality of child nodes based on a network connection mode of the end-to-end communication.
Wherein the child nodes are group user GCs.
It should be noted that, based on the network connection mode of the end-to-end communication, the network switching master node can perform the end-to-end communication with each sub-node respectively, so as to reduce the proportion of forwarding communication information by the intermediate node, enable the network switching master node to obtain the communication information of a plurality of sub-nodes more quickly and accurately, and improve the communication efficiency.
Step S303, in the case that the child node is determined to be faulty according to the network state information of the child node, a first switching message is generated.
Step S304, a first switching message is sent to the child node, so that the child node switches its network connection mode to a network connection mode supporting end-to-end communication.
Note that, steps S303 to S304 in the present embodiment are the same as steps S101 to S102 in the embodiment shown in fig. 1, and are not described here again.
In this embodiment, by establishing the first communication connection and the second communication connection with the plurality of child nodes respectively, the network switching master node can communicate with the plurality of child nodes through a plurality of different communication connection modes, and the communication modes are expanded; under the condition that the child node is determined to be faulty according to the network state information of the child node, the generated first switching message can be sent to the child node, so that the child node switches the network connection mode of the child node from the network connection mode based on the mesh network to the network connection mode supporting end-to-end communication, the faulty child node and the network switching master node can directly communicate, the proportion of communication interruption caused by the fault of the factor node is reduced, the possibility of network paralysis is further reduced, and the system stability of the communication network is improved.
In some implementations, the network state information includes: connection status information of the child node in the first communication connection; determining that the child node fails according to the network status information of the child node in step S303 includes: determining that the child node has a connection fault under the condition that the connection state information in the first communication connection is determined to be indicative of the non-communication between the child node and the main node; the master node owns the device GO for the group.
For example, obtaining network state information of a child node includes: each interval is preset in time length, and a measurement indication message is sent to the child node; and responding to the measurement result information fed back by the child node, and acquiring the network state information of the child node.
The preset time length can be a specific time interval of 5 seconds, 10 seconds and the like, so that the master node can regularly measure the network connection state of a plurality of sub-nodes, and therefore the connection state information of the sub-nodes in the first communication connection can be obtained in real time, and the connection state information is more accurate.
For example, the connection state information of the child node in the first communication connection may include: and presetting heartbeat messages between the main node and the child nodes. The heartbeat message is reported by the child node at fixed time, so that the master node can know the communication connection condition between the child node and the master node. If the main node does not receive the heartbeat message reported by the sub-node in the preset period, or if the received heartbeat message is wrong (for example, the preset heartbeat message carries the heartbeat times, if the heartbeat times received at a certain time are not arranged in sequence, or the heartbeat times are messy codes), the sub-node is not communicated with the main node, namely, the sub-node has connection fault.
As another example, the connection status information of the child node in the first communication connection may further include: and (3) verifying a connection identifier, wherein the connection identifier can represent the communication connection state between the child node and the main node. And comparing the connection identifier to be verified with a preset connection identifier to determine whether the connection identifier to be verified is identical with the preset connection identifier. Under the condition that the connection identifier to be verified is the same as the preset connection identifier, the communication between the child node and the main node is determined; otherwise, determining that the child node is not communicated with the main node.
The connection state information of the child node in the first communication connection is used for determining whether the child node has a connection fault or not, so that the child node with the connection fault can be timely detected, the child node with the connection fault can be quickly repaired and processed, the proportion of communication interruption is reduced, and the communication efficiency is improved.
In some implementations, the network state information includes: signaling configuration information and connection state information of the child node in the first communication connection; determining that the child node fails according to the network status information of the child node in step S303 includes: and under the condition that the signaling configuration information is different from the preset configuration information of the child node and the connection state information is used for representing that the child node is not communicated with the main node, determining that the child node has abnormal configuration faults.
The signaling configuration information may include: at least one of service configuration information, network parameter configuration information and configuration information of a communication system.
Comparing the signaling configuration information with preset configuration information of the child node to obtain a first comparison result; judging the connection state information of the node in the first communication connection to determine whether the sub-node and the main node are in a communication state or a non-communication state; the communication conditions of the sub-nodes can be measured in multiple dimensions, so that the fault conditions of the sub-nodes can be judged more accurately. Under the condition that the signaling configuration information is different from the preset configuration information of the child node and the connection state information is used for representing that the child node is not communicated with the main node, the child node is determined to have abnormal configuration faults, so that the child node can be corrected in a targeted mode conveniently, and normal communication can be quickly recovered by the child node.
It should be noted that, the correction of the configuration information of the child node may be performed through a network connection mode supporting end-to-end communication between the master node and the child node, so that the child node with a failure may quickly and accurately obtain the corrected configuration information of the master node, reduce the error proportion of the configuration information, and accelerate the repair efficiency of the child node.
In some implementations, the network state information includes: real-time traffic handling capacity of child nodes; determining that the child node fails according to the network status information of the child node in step S303 includes: acquiring the service processing capacity of the child node; and determining that the sub-node has network congestion fault according to the real-time service processing capacity of the sub-node and the service processing capacity of the sub-node.
The service processing capacity of the sub-node can represent the maximum peak value of the service data volume which can be processed by the sub-node, and the real-time service processing capacity of the sub-node is compared with the service processing capacity of the sub-node, so that whether the service data volume processed by the sub-node at the current moment exceeds the processing capacity of the sub-node can be determined, and further, the network congestion fault of the sub-node is determined under the condition that the real-time service processing capacity of the sub-node exceeds the service processing capacity of the sub-node is determined.
When the sub-node has network congestion fault, the service data volume of the sub-node needs to be split so as to reduce the service processing pressure of the sub-node. For example, through a network connection mode supporting end-to-end communication between the master node and the child node, part of the service of the child node is shunted to the master node, so that the master node can relieve the service processing pressure of the child node.
In some implementations, after sending the first switching message to the child node for the child node to switch its network connection mode to a network connection mode supporting end-to-end communication, the method further includes: generating a second switching message under the condition that the child node is determined to be recovered to be normal according to the network state information; and sending a second switching message to the child node according to the second communication connection so that the child node switches the network connection mode to the connection mode of the mesh network.
Wherein the second handover message is used to instruct the child node to resume its original network connection mode (e.g., a mesh network connection mode, etc.).
When the network state information obtained by the master node can represent that the communication between the sub-node and the master node based on the first communication connection (such as the connection mode of the mesh network) is recovered to be normal, the sub-node can continue to communicate with the master node through the first communication connection, so that the connection mode between the sub-node and the master node based on the second communication connection (such as the end-to-end communication connection) can be disconnected, and the master node can communicate with the sub-node through the connection mode of the mesh network, so that the processing pressure of the master node is reduced. At this time, the master node does not need to maintain end-to-end communication connection with the sub-nodes, so that the master node can release communication resources for processing communication information of other fault sub-nodes, and system stability of the communication network is improved.
In some implementations, before determining that the child node returns to normal according to the network state information, the method further includes: and according to the second communication connection, configuring communication resources used by the child node by adopting preset configuration information of the child node so as to enable the child node to acquire the communication resources required by the child node.
For example, the preset configuration information may include: at least one of preset service configuration information, preset network parameter configuration information and configuration information of a preset communication system.
And the second communication connection is adopted, and the preset configuration information of a plurality of different dimensions required by the child node is sent to the node, so that the child node can quickly and accurately acquire the required communication resources, the communication efficiency of the child node is improved, the possibility of failure of the child node is reduced, and the use experience of a user is improved.
In some implementations, determining that the child node is restored to normal based on the network state information includes: and determining that the child node is restored to normal under the condition that the child node is determined to meet at least one of the following conditions:
the connection state of the child node in the first communication connection is communication;
the real-time service processing capacity of the child node is matched with the service processing capacity of the child node;
The signaling configuration information fed back by the child node is the same as the preset configuration information.
By judging the different angles of the conditions, the communication state of the child node can be clarified, and whether the child node is recovered to be normal or not (for example, the child node is recovered to be in a state of normal communication by using an initially configured network connection mode, and the like) is further determined, so that the child node recovered to be normal is processed in time, the network connection mode of end-to-end communication between the child node and the main node can be recovered to the initially configured network connection mode, the processing pressure of the main node is reduced, the main node can conveniently release more communication resources for processing other fault nodes, the possibility of network paralysis is reduced, and the system stability of a communication network is improved.
Fig. 4 is a flow chart illustrating a network switching method according to an embodiment of the present application. The network switching method can be applied to the network switching child node. As shown in fig. 4, the network handover method in the embodiment of the present application includes, but is not limited to, the following steps.
Step S401, transmitting the network status information of the child node to the master node.
The network state information is information representing that the child node fails. For example, a failure in which communication connection is interrupted by a child node, a failure in which network congestion occurs by a child node, a failure in which configuration information obtained by a child node is abnormal, or the like. The above types of faults occurring to the child nodes are only exemplified, and specific processing can be performed according to actual situations, and other types of faults occurring to non-illustrated child nodes are also within the protection scope of the present application, and are not described herein.
The information of the occurrence of the faults of the child nodes is sent to the main node, so that the main node can timely and accurately acquire that the child nodes are abnormal, and the child nodes are rapidly subjected to fault processing, so that the communication of the child nodes can be rapidly recovered to be normal, the proportion of poor user experience caused by communication interruption is reduced, and the communication stability between the network switching child nodes and the network switching main node is improved.
Step S402, in response to the first switching message sent by the master node, the network connection mode of the child node is switched to a network connection mode supporting end-to-end communication.
The first switching message is a message for instructing the child node to switch the communication network connection mode.
Because the communication connection between the master node and the slave node is based on a non-end-to-end communication connection (e.g., a Mesh network-based communication connection, etc.) before the first handover message is obtained, if the communication of the slave node is interrupted, the communication of other devices connected with the slave node is affected (e.g., the configuration information of the master node cannot be obtained in time, or the obtained information sent by the master node is error information, etc.); the network connection mode of the sub-node is switched to the network connection mode supporting end-to-end communication, so that the sub-node can directly communicate with the main node, and the speed of acquiring information from the main node is increased; the sub-node can communicate with other devices through the forwarding of communication information between the sub-node and the main node, so that the possibility of paralysis of the communication network is reduced, and the system stability of the communication network is improved.

Fig. 7 shows a block diagram of a network switching system according to an embodiment of the present application. As shown in fig. 7, the network switching system may include the following devices.
A Mesh network connection-based network switching master node 710 and a plurality of network switching sub-nodes (e.g., a first sub-node 721, second sub-nodes 722, … …, a kth sub-node 72K, an nth sub-node 72N, etc., N representing the number of sub-nodes, N being an integer greater than or equal to 1, K being an integer greater than 2 and less than N).
It should be noted that, the network switching master node 710 may establish end-to-end communication with any one of the network sub-nodes. For example, the network switching master node 710 may not only establish a multi-hop Mesh network connection with the second sub-node 722 and the kth sub-node 72K, but also directly establish an end-to-end network connection with the kth sub-node 72K, so that the kth sub-node 72K can communicate with other sub-nodes through multiple network connection modes, thereby improving communication efficiency, reducing possibility of network paralysis, and improving system stability of the communication network.
Fig. 8 is a flow chart illustrating a working method of a network switching system according to an embodiment of the present application. As shown in fig. 8, the operation method of the network switching system includes, but is not limited to, the following steps.
In step S801, a first communication connection is established between the network switching master node 710 and the plurality of network switching child nodes according to a connection mode of the mesh network. Meanwhile, the network switching master node 710 starts the master control end of the Mesh network assistant, and the plurality of network switching sub-nodes (such as the second sub-node 722 or the kth sub-node 72K, etc.) start the clients of the Mesh network group; the network switch master node 710 establishes a second communication connection (e.g., an end-to-end communication connection) with the plurality of network switch child nodes through the WiFi-P2P network function component.
For example, the first communication connection may be established in the following manner: the network switching master node 710 constructs Mesh network connection with the first sub-node 721, the second sub-nodes 722, … …, the kth sub-node 72K, the nth sub-node 72N, and the like according to a Mesh network standard protocol.
For another example, after the network switching master node 710 receives the Mesh network connection establishment completion message fed back by each network switching sub-node, the network switching master node 710 may send an indication of starting the WiFi-P2P software function to the plurality of network switching sub-nodes, so that each network switching sub-node may start the WiFi-P2P function.
The network switching master node 710 serves as a GO in a WiFi-P2P network, and each network switching child node serves as a GC in the WiFi-P2P network.
Step S802, the network switching master node 710 monitors the network states of the plurality of network switching sub-nodes through the master control end of the Mesh network assistant, and obtains the connection state information of each network switching sub-node in the first communication connection; and saving the connection state information in the first communication connection to a child node state information table.
Wherein the child node state information table may include: network mode of each network switching, working state information of the network switching sub-node, etc.
In step S803, the network switching master node 710 periodically transmits a measurement message to the second child node 722 and the kth child node 72K.
Wherein the measurement message is used to obtain network status information of the second child node 722 and the kth child node 72K. The network status information may include: at least one of connection state information of the second sub-node 722 in the first communication connection (e.g., mesh network connection), real-time traffic handling capacity of the second sub-node 722, and signaling configuration information. The connection status information is used to characterize whether the second child node 722 is in communication with the network switching master node 710, for example, a heartbeat message may be used to characterize the communication connectivity status between the two nodes.
If the network switching master node 710 is capable of receiving the correct heartbeat message sent by the second child node 722 (or the kth child node 72K) within the preset period, it is indicated that the second child node 722 (or the kth child node 72K) is connected to the network switching master node 710; otherwise, if the network handover master node 710 does not receive the correct heartbeat message sent by the second child node 722 (or the kth child node 72K) within the preset period, or the received heartbeat message is an abnormal message, it indicates that the second child node 722 (or the kth child node 72K) is not connected to the network handover master node 710, and there may be a communication failure.
In step S804, the kth child node 72K feeds back the network state information obtained by its measurement in the first communication connection state to the network switching master node 710 in response to the measurement message.
In step S805, the network switching master node 710 determines that the kth child node 72K is not connected to the network switching master node 710 according to the network status information fed back by the kth child node 72K, and generates a first switching message.
Wherein the first switching message is for causing the kth child node 72K to switch its network connection mode to a network connection mode supporting end-to-end communication.
In step S806, the network switching master node 710 transmits the first switching message to the kth child node 72K through the second communication connection.
In step S807, the kth sub-node 72K, after receiving the first handover message, enables the kth sub-node 72K to perform end-to-end communication with the network handover master node 710 based on the second communication connection.
In step S808, the kth child node 72K transmits the connection state information thereof in the first communication connection obtained by the measurement to the network switching master node 710 through the second communication connection.
In step S809, the network switching master node 710 updates the child node status information table according to the obtained network status information sent by the different network switching child nodes.
In step S810, according to the updated status information table of the sub-nodes, it is determined that the connection status information of the kth sub-node 72K in the first communication connection can indicate that the first communication connection between the kth sub-node 72K and the network switching master node 710 is restored, and the network switching master node 710 generates a second switching message and sends the second switching message to the kth sub-node 72K through the second communication connection.
Step S811, after receiving the second switching message, the kth child node 72K switches the communication connection mode between itself and the network switching master node 710 from the second communication connection to the first communication connection; and the kth child node 72K communicates with the network switching master node 710 based on the first communication connection.
In this embodiment, a first communication connection and a second communication connection are established between the network switching master node 710 and the plurality of network switching sub-nodes, so that the network switching master node 710 can monitor connection state information of the plurality of network switching sub-nodes in the first communication connection, and can accurately determine whether each network switching sub-node has a fault in real time; in the case that it is determined that the first communication connection between a certain sub-node and the network switching master node 710 is in an interrupted state, the communication connection between the sub-node and the network switching master node 710 can be switched to the second communication connection in time, so that it is ensured that the sub-node can still communicate with other nodes through the second communication connection mode (for example, directly communicate with the network switching master node 710 based on the second communication connection, or communicate with other nodes through forwarding of the network switching master node 710, or the like), and the failure rate of other nodes which cannot communicate due to the failure of the factor node can be reduced. In addition, when the connection state information of the faulty sub-node in the first communication connection is detected, the first communication connection between the kth sub-node 72K and the network switching master node 710 can be represented, and then the faulty sub-node is switched from the second communication connection back to the first communication connection, so that the faulty sub-node can be switched to different available network modes (for example, the WiFi-P2P network connection is used as a standby communication connection of the Mesh network connection) in good time, the possibility of network paralysis is reduced, and the system stability of the communication network is improved.
