Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. indicate an orientation or a positional relationship based on that shown in the drawings or that the product of the present invention is used as it is, this is only for convenience of description and simplification of the description, and it does not indicate or imply that the device or the element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

With the development of network technology, star structures, ring structures, bus structures, tree structures and the like of traditional local area networks all play a role in various fields, and stable network connection and a large amount of data traffic are provided for billions of people all over the world. But the inherent network property deficiency of these network structures is also gradually emerging. For example, in a star structure, once a single point failure problem of a central node occurs, the whole network is broken down, and for example, in a bus structure, many buses need to be deployed to connect all communication nodes, which results in a large deployment cost and a large implementation difficulty.

In view of the above problems in the network structure, Mesh networks, which are Mesh networks, have been developed, and Mesh networks are mainly used in wireless networks, such as bluetooth Mesh, Wifi Mesh, and Zigbee Mesh.

However, while overcoming the defects existing in other network structures, the Mesh network also has some problems, for example, the network construction is complex, and the network is flexible and dynamic, so that the difficulty of troubleshooting and network optimization is high, and how to quickly troubleshoot the wireless Mesh network, improve the stability and optimize the reliability becomes the problem that the technicians need to solve most urgently.

In order to solve the above problems, in the prior art, a wireless packet capturing tool is generally used to analyze the network condition of the wireless Mesh network. Because the wireless Mesh network is complex to construct and the network structure is flexible in dynamic change, the current mainstream investigation method usually performs packet capturing analysis by matching a hardware packet capturing device and a computer, and the method can analyze the interactive message content of each node in the network in detail and can also examine the communication condition between each node, such as the signal strength, routing relationship, time consumption and other information.

Referring to fig. 1, fig. 1 is an exemplary diagram of a wireless zigbee Mesh network according to an embodiment of the present invention, the zigbee Mesh network in fig. 1 includes 4 nodes, which are respectively node 0x378A, node 0xC691, node 0x9FBD, and node 0x0000, and when the node 0x378A needs to send a packet to the node 0x0000, the wireless packet capturing tool is used to capture a forwarding packet in the wireless Mesh network.

Referring to fig. 2, fig. 2 is an exemplary screenshot of a captured forwarding packet according to an embodiment of the present invention. The Timestamp in fig. 2 is generally represented by Timestamp, the Stack is generally represented by Stack, the Packet Information is generally represented by Packet Information, the destination node group is generally represented by PAN dst, the source MAC is generally represented by MAC dst, the destination MAC is generally represented by MAC dst, the MAC sequence is generally represented by MAC seq, the source NWK is generally represented by NWK src, and the destination NWK is generally represented by NWK dst, where NWK is the network layer of ZigBee, and as can be seen from the Packet in fig. 2, the network layer address is node 0x378A and wants to send a command to node 0x0000, and first, node 0x378A sends the Packet to node 0xC691, node 0xC fb691 sends the Packet to node 0x9FBD, and then node 0x9 d sends the Packet Information to node 0x 0000. For each message, the consumption duration, routing relation, signal strength and the like of the message transmitted by the message can be obtained through a packet capturing tool.

An example of the transmission of the second packet in fig. 2 is as follows:

as can be seen from the example of the transmission condition of the second packet, the communication duration Time Delta when the second packet is transmitted is 0.00876s, and the connection Quality Link Quality is-55 dBm.

According to the method for analyzing the network condition through the packet capturing tool, the analysis message pays too much attention to details, the overall form of the network structure is ignored, the overall network structure of the network cannot be analyzed from multiple dimensions, the routing relation and the communication quality of different nodes of the whole network cannot be analyzed rapidly and parallelly, and the attribute change condition and the coupling parameter dynamic change condition between the nodes cannot be checked directly. Once data reporting is abnormal, it is difficult to analyze through a captured single message.

In view of this, the embodiment of the present invention analyzes the wireless network from another aspect, that is, the wireless network is firstly visualized, and troubleshooting and network optimization are performed based on the visualized wireless network, so that difficulty of troubleshooting and network optimization is greatly reduced, which will be described in detail below.

Referring to fig. 3, fig. 3 is a schematic view illustrating an application scenario applicable to an embodiment of the present invention, in fig. 3, a wireless network includes a border router 40 and a device node 30, which communicate with each other in a wireless communication manner, which may be, but is not limited to, bluetooth, Wifi, Zigbee, and the like. The border router 40 communicates with the server 10 via a network, and the server 10 communicates with the display terminal 20 via a network, and the network communication may be wireless communication or wired communication, or may be directly connected or indirectly connected.

The server 10 may be a physical computer, or may be a virtual machine capable of implementing the same function as the server 10, or may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers, and the like, the server 10 may generate a topology structure, and transmit the topology structure to the display terminal 20 for visual display, the server 10 may also provide a web address to the display terminal 20, the display terminal 20 displays a visual result by accessing the web address, and a user may also directly view the visual result by using a web browser of the server 10.

The display terminal 20 is a device having a display function, and may specifically be, but is not limited to, an intelligent control panel, a smart phone, a tablet computer, a notebook computer, a desktop computer, and a smart watch.

The border router 40 is also called an edge router, and is a device that routes data packets between one or more local area networks and a backbone network, and in the wireless network according to the embodiment of the present invention, the border router 40 mainly functions as a gateway thereof, and maintains address allocation and the like of the whole wireless Mesh network.

The device nodes 30 include forwarding nodes having a capability of communicating with the border router, for example, the device nodes 30 directly connected to the border router 40 in fig. 3, where the forwarding nodes are nodes with a forwarding function and are used to implement a packet forwarding function between nodes in the wireless network. The forwarding node stores neighbor table and routing table information, and the neighbor table records the device nodes with physical links between the device nodes and the forwarding node. In the smart home field, the forwarding node may be a smart socket, a smart wall socket, or the like.

The device nodes 30 may also include end nodes, which refer to devices with low power consumption and no forwarding functionality. In the intelligent home field, the terminal nodes can be temperature and humidity sensors, human body sensors, dynamic and static sticking sensors and the like.

The device node 30 may also include one or more of an end node and a forwarding node, and of course, one forwarding node may also have a physical link with a plurality of other forwarding nodes at the same time, or a physical link with a plurality of end nodes at the same time, and so on. The routing table records the node information to be forwarded by the forwarding node, and ensures that the data packet is forwarded by selecting a proper next-hop forwarding path according to the forwarding path description of the routing table after reaching the forwarding node through the previous hop.

Taking a home application scenario as an example, please refer to fig. 4, fig. 4 shows a schematic view of a home scenario applicable to the embodiment of the present invention, in fig. 4, a wireless network includes a home border router 401, an intelligent wall socket 301, a temperature and humidity sensor 303, and a Total Volatile Organic compound TVOC (TVOC) sensor 304, and a dotted line in fig. 4 represents a wireless connection, for example, the TVOC sensor 304 is wirelessly connected to the intelligent wall socket 301.

It is understood that although the server 10 and the display terminal 20 are not shown in fig. 4, in practice, the home border router 401 may be in communication with the server 10 to transmit the neighbor list to the server 10 through the home border router 401, so that the server 10 generates the topology of the wireless network according to the neighbor list and visualizes the wireless network, and the display terminal 20 may be in communication with the server 10 to visualize the topology and the communication status information transmitted by the server 10.

In the application scenarios of fig. 3 and fig. 4, an embodiment of the present invention further provides a hardware structure block diagram of a computer device 50, where the computer device 50 may be the server 10 in fig. 3 and fig. 4, or may be the display terminal 20 in fig. 3 and fig. 4. Referring to fig. 5, fig. 5 is a block diagram illustrating a hardware structure of a computer device 50 according to an embodiment of the present invention, where the computer device 50 includes a processor 51, a memory 52, a bus 53, and a communication interface 54. The processor 51 and the memory 52 are connected by a bus 53, and the processor 51 communicates with an external device via a communication interface 54.

The processor 51 may be an integrated circuit chip having signal processing capabilities. In implementation, the steps of the above method may be performed by integrated logic circuits of hardware or instructions in the form of software in the processor 51. The Processor 51 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components.

The memory 52 is used for storing a program, for example, the first network visualization processing apparatus 100 or the second network visualization processing apparatus 200 in the embodiment of the present invention, and each of the first network visualization processing apparatus 100 or the second network visualization processing apparatus 200 includes at least one software functional module which can be stored in the memory 52 in the form of software or firmware (firmware), and the processor 51 executes the program after receiving the execution instruction to implement the network visualization processing method in the embodiment of the present invention.

The Memory 52 may include a Random Access Memory (RAM) and may also include a non-volatile Memory (non-volatile Memory). Alternatively, the memory 52 may be a storage device built in the processor 51, or may be a storage device independent of the processor 51.

The bus 53 may be an ISA bus, a PCI bus, an EISA bus, or the like. Fig. 5 is indicated by only one double-headed arrow, but does not indicate only one bus or one type of bus.

It will be understood by those skilled in the art that the structure shown in fig. 5 is merely illustrative and is not intended to limit the structure of the computer device 50 described above. For example, computer device 50 may also include more or fewer components than shown in FIG. 5, or have a different configuration than shown in FIG. 5.

Based on the application scenarios in fig. 3 and fig. 4, an embodiment of the present invention further provides a network visualization processing method applied to the server 10 in fig. 3 and fig. 4, please refer to fig. 6, and fig. 6 shows a network visualization processing method applied to a server according to an embodiment of the present invention, where the method includes the following steps:

step S100, receiving a neighbor table sent by each forwarding node through a boundary router, wherein the neighbor table comprises adjacent communication links existing in the equipment node and corresponding forwarding nodes and signal strengths of the communication links.

In this embodiment, as a specific implementation manner, the device node may include one or more terminal nodes, may also include one or more forwarding nodes, or includes both a terminal node and other forwarding nodes.

In this embodiment, the neighbor table of the forwarding node is used to store link information between the forwarding node and each device node adjacent to the forwarding node, where the link information includes communication links between the forwarding node and each device node adjacent to the forwarding node and signal strengths of the communication links. As a specific implementation manner, the forwarding node may actively send a probe request frame or a frame listen preset frame to each device node in the wireless network to collect information of its neighbor, and once a response frame of another device node to the probe request frame is received or the received preset frame of another device node is analyzed, if a neighbor matching relationship is met, a neighbor relationship may be established with the device node, and link information between the forwarding node and the neighbor is updated to a neighbor table.

In this embodiment, each forwarding node may send its own neighbor table to the border router in real time or periodically, and the border router 40 summarizes the neighbor tables of each forwarding node and sends the summarized neighbor tables to the server 10.

In this embodiment, the signal strength between the forwarding node and the device node 30 is different because the relative positions of the forwarding node and the device node 30 are different, or the communication performance of the forwarding node and the device node 30 is different, and the signal strength between the forwarding node and the device node 30 is also different, for example, when a wall exists between the forwarding node and the device node 30 and when no wall exists, the corresponding signal strength is different, the antenna quality of the device node 30 is different, and the signal strength between the device node and the forwarding node is also different. Taking a forwarding node as an intelligent wall switch as an example, table 1 is an example of a neighbor table of the intelligent wall switch.

TABLE 1

Step S110, generating a topological structure of the wireless network according to the neighbor table; the topology structure comprises communication state information among equipment nodes in the wireless network, and the communication state information comprises communication links among the equipment nodes and signal strength of the communication links.

In the present embodiment, the topology is an abstract representation method that describes actual positions and relationships of a plurality of objects using only points or lines, regardless of physical attributes such as sizes and shapes of the objects. The topological structure does not concern the details of objects and the mutual proportion relation, but only represents the mutual relation among a plurality of objects in a certain range in the form of a graph. As a specific implementation, the device nodes 30 (including forwarding nodes and end nodes) may be characterized by points (also referred to as vertices) in the topology, the communication links between the device nodes 30 characterized by two vertices in the topology are represented by edges between the two vertices, and the signal strengths of the communication links between the device nodes 30 are characterized by weights of the edges between the two vertices in the topology.

And step S120, sending the topological structure to a display terminal, and enabling the display terminal to visually display the topological structure and the communication state information.

In this embodiment, the server 10 sends the topology structure to the display terminal 20, and the display terminal 20 visually displays the topology structure and the communication status information.

In this embodiment, please refer to fig. 7, fig. 7 shows an exemplary diagram of a wireless network visualization provided by an embodiment of the present invention, in fig. 7, in a topology structure, a temperature and humidity sensor, a TVOC sensor, an intelligent wall socket, and an edge router are all represented by a vertex in the topology structure, taking the TVOC sensor and the intelligent wall socket as an example, an edge between the two represents that a communication link exists between the two, and a number shown on the edge is a signal strength during signal transmission, that is, the signal strength of a signal transmitted from the TVOC sensor to the intelligent wall socket is 121.

According to the method provided by the embodiment of the invention, the visualization of the wireless network is realized by visually displaying the topological structure, so that the efficiency of troubleshooting and network optimization is improved based on the visualized wireless network.

It should be noted that, in this embodiment, the number of forwarding nodes may be one or multiple, when there are multiple forwarding nodes, the multiple forwarding nodes are all in communication connection with the border router, at this time, each forwarding node corresponds to one neighbor sub-table, and the border router aggregates the multiple neighbor sub-tables sent by the multiple forwarding nodes to obtain a neighbor table.

In this embodiment, because the structure of the wireless network has a characteristic of flexible change, in order to facilitate a user to perform troubleshooting and network optimization according to dynamic changes of the wireless network, an embodiment of the present invention further provides a method for corresponding a topology structure to a corresponding time point, so that the user can query the topology structure at a specified time point, please refer to fig. 8, which shows another network visualization processing method applied to a server provided by the embodiment of the present invention, where the method includes the following steps:

step S130, acquiring the receiving time of the receiving neighbor table, and establishing the corresponding relation between the receiving time and the topological structure.

In this embodiment, the topology corresponding to the reception time is generated from the neighbor table received at the reception time. As a specific expression, an identifier may be set for each topology, and a corresponding relationship between the identifier and the corresponding receiving time is stored, for example, the corresponding relationship is shown in table 2:

TABLE 2

Topology identification	Receiving time
		1	2021-9-9 09:30

Meaning that the topology identified as 1 is generated from the neighbor table received 2021-9-909: 30, which represents the communication state information at 2021-9-909: 30.

Step S140, determining the communication state information of each device node in the topology structure at the receiving time according to the corresponding relationship.

In this embodiment, after the corresponding relationship between the receiving time and the topology structure is established, the corresponding relationship may be stored, so that the user may query the topology structure at a specified time point or within a specified time range, and further perform more accurate and more comprehensive backtracking or tracking on the dynamic change of the topology structure of the wireless network. For example, a neighbor table and a router generated by each forwarding node are collected in real time or according to a preset period, then a topology structure representing the communication state between equipment nodes in the wireless network is generated based on the neighbor table and the router table collected at the moment, and by comparing the topology structures at different moments, the change situation of the topology structure of the wireless network in a certain period can be known, and then the change situation of the communication state between the equipment nodes in the wireless network can be known, so that the fault investigation can be performed on the equipment nodes with the communication state changed from connection to disconnection, or the performance optimization can be performed on the equipment nodes with the communication state optimized to poor.

In this embodiment, in order to more vividly display a forwarding path selected between node devices and more intuitively display the forwarding path, so as to facilitate a maintenance worker to quickly locate a problem, an embodiment of the present invention further provides another method for visually displaying the forwarding path, please refer to fig. 9, where fig. 9 shows another network visualization processing method applied to a server, provided by an embodiment of the present invention, the method includes the following steps:

step S150, receiving a routing table sent by the boundary router, wherein the routing table is sent by the forwarding node to the boundary router, the routing table comprises a previous-hop node corresponding to the forwarding node and a next-hop node corresponding to the previous-hop node, the previous-hop node is used for sending an equipment node of data to be forwarded to the forwarding node, and the next-hop node is used for representing the equipment node to which the forwarding node needs to send the data to be forwarded.

In this embodiment, the forwarding node includes a neighbor table and a routing table, the forwarding node transmits the neighbor table to the boundary router 40 and also transmits the routing table to the boundary router 40, the routing table includes a previous-hop node corresponding to the forwarding node and a next-hop node corresponding to the previous-hop node, the previous-hop node of the forwarding node is one of the device nodes that transmits data to be transmitted to the forwarding node, the next-hop node of the forwarding node is one of the device nodes that transmits data to be transmitted to the forwarding node, that is, the data to be transmitted is transmitted to the forwarding node from the previous-hop node, and the forwarding node forwards the data to be transmitted to the next-hop node corresponding to the previous-hop node. Taking the forwarding node as an intelligent wall switch as an example, table 3 is an example of a routing table of the intelligent wall switch.

TABLE 3

Last hop node	Next hop node
		TVOC sensor	Boundary router

It should be noted that, routing algorithms adopted by the wireless network are different, the selection of forwarding paths is also different, and accordingly, information in the previous-hop node and the next-hop node in the routing table is also different. Taking the wireless Mesh network as an example, factors affecting the routing path of the wireless Mesh network are many, such as the communication signal strength of a link, the routing layer number of communication, the power consumption consumed by communication, and the like. For example, the topology of the wireless network can be visually displayed for flooding routing relationships.

Step S160, determining a forwarding path corresponding to the data to be forwarded from the previous-hop node to the next-hop node according to the routing table.

In this embodiment, by visually displaying the forwarding paths, all reachable paths from a certain node to other nodes and how many route transit nodes are required for each reachable path can be intuitively known.

Step S170, generating a topological structure corresponding to the wireless network according to the neighbor table and the forwarding path; the topology also includes forwarding paths between device nodes in the wireless network.

To show the visualization of the forwarding path more clearly, please refer to fig. 10, where fig. 10 shows an exemplary diagram of the visualization of the forwarding path provided by the embodiment of the present invention, in fig. 10, the TVOC reports the reported data to the border router through the node intelligent wall switch with forwarding function, and the forwarding path of the data is shown as a solid line with an arrow in fig. 10: TVOC- > smart wall switch- > border router.

In this embodiment, as a specific implementation manner, in order to more vividly display the forwarding path, the forwarding path may be presented in an animation or highlight manner, and when a mouse stays on any forwarding node or terminal node, the forwarding node or terminal node may be highlighted, and the forwarding path of data in the forwarding node or terminal node may be animated or highlighted, so that a maintenance worker can quickly locate a problem.

It should be noted that, in this embodiment, there may be one or more forwarding nodes, and when there are multiple forwarding nodes, the multiple forwarding nodes are all in communication connection with the border router, at this time, each forwarding node corresponds to one routing sub-table, and the border router summarizes the multiple routing sub-tables sent by the multiple forwarding nodes to obtain a routing table.

In this embodiment, as a specific application mode, a technician may also visually check multiple path selection relationships of data communication according to a visualized display condition of a topology structure before and after a change of a wireless network, and if data to be forwarded cannot be forwarded as expected, may analyze the signal strength in a graph, for example, because the communication quality of a certain link is poor, the link needs to be optimized, and at this time, the technician may have a basis that is real enough to adjust the position of a device or adjust the sensitivity of the device to receive signals or the communication links between device nodes, so as to perform network optimization. The following provides an example of analyzing wireless network communication conditions according to the visual display conditions of the topology structures before and after the wireless network changes.

With fig. 7 as a visual example before the wireless network changes, it can be seen from fig. 7 that the connection relationship of all the devices and the reachable paths and connection signal quality of the communication between the devices, for example, the signal from the TVOC sensor 304 to the smart wall socket 301 is 121, which is a premium signal, and the signal strength from the smart wall socket 301 to the smart wall socket 301 is 127 and 123, which are also premium signals.

In fig. 7, two smart wall switches 302 and 1 TVOC sensor 304 are added, please refer to fig. 11, fig. 11 shows a visual example diagram after the wireless network is changed according to the embodiment of the present invention, and it can be seen from fig. 11 that, in the changed wireless network, the signal strength from the TVOC sensor 304 to the smart wall socket 301 is changed from 121 (excellent) to 102 (excellent). Meanwhile, the connection relationship between the smart wall socket 301 and the smart wall switch 302 is also increased, and the message reported by the newly added TVOC sensor 304 reaches the home border router 401 through the smart wall switch 302.

As can be analyzed by comparing fig. 7 with fig. 11, when the message reported by the newly added TVOC sensor is sent to the smart wall switch 302, the smart wall switch 302 compares all the paths that can be forwarded to the home border router 401, and after evaluation, it is found that the signal from the smart wall switch 302 to the smart wall socket 301 is only 85 (good), and the signal strength reaching the other smart wall switch 302 is 77 (medium), so that the link of 142 (good) directly reported to the home border router 401 is finally selected.

Through the analysis, technicians can visually check the selection relationship of multiple paths of data communication and the root cause why a certain path is not selected, and in addition, once the message reported by the TVOC sensor cannot directly reach the home border router 401 and the message is lost midway, the message can be analyzed from the signal strength in the graph, which is caused by the poor communication quality of a certain link and needs to be optimized.

In this embodiment, in addition to showing information in a neighbor table and/or a routing table in a visualized form, an embodiment of the present invention further provides another method for visually showing connection information between a forwarding node and a device node, please refer to fig. 12, where fig. 12 shows another network visualization processing method applied to a server according to an embodiment of the present invention, the method includes the following steps:
