The implementation details of drawing the network topology diagram in this embodiment will be described in detail below. The following content is only the implementation details provided for the convenience of understanding, and is not necessary for implementing the solution.

Referring to Fig. 1, Fig. 1 is a flowchart of drawing a network topology diagram in the first embodiment of the present invention, including:

S1. Obtain a topology data set, and perform node analysis on the topology data set to generate a node control parameter set.

Topology refers to the connection between devices, parameters, etc. Specifically, such as the topology in the field of computer networks (ComputerNetwork Topology), refers to the distribution and mutual connection status of network devices composed of computers. Further, the topology map Refers to drawing the network equipment composed of computers on the corresponding diagram according to the topology, which is the topology diagram. The general topology diagram requires the location of the device, the type of device name and the connection medium between the devices to be marked on the diagram. type etc.

The topology data set of the present invention includes but not limited to node ID, node name, node type, node location data, node type, connection node ID and link type array corresponding to the node ID, such as the network equipment composed of the above-mentioned computers When it is necessary to draw a topology map, it is first necessary to know topological data such as node IDs, node names, node types, node location data, node types, connection node IDs, and link type arrays corresponding to the node IDs of different network devices. Gather topology data of different network devices to obtain topology data sets, such as topology data of workstation nodes, topology data of switch nodes, topology data of router nodes, topology data of server group nodes, etc.

Preferably, the topology data set can be in the form that the client sends a topology data acquisition request to the background server, and the background server receives the acquisition request and returns the topology data set, wherein the format of the topology data set is Including but not limited to yaml, xml and json.

In detail, the generation of node control parameter sets by performing node analysis on the topology data set can refer to the detailed implementation flow diagram in Figure 2, including:

S11. Extracting the node ID, the node type, and the node location data from the topology data set;

S12. According to the node ID, the node type and the node location data, use the front-end network topology map drawing technology to generate the node control parameter set in the pre-built original topology map.

The front-end network topology drawing technology may adopt a network topology drawing method based on HTML5, a Web-based JGraphx topology drawing method, an echarts network topology drawing method, and the like.

Further, the original topology map can use a blank web page drawn in advance by HTML technology, according to the above-mentioned HTML5, Web-based JGraphx, echarts and other network topology map drawing methods, and use the node ID, the node type and the The node position data is used as a parameter, the node information is drawn in the blank webpage, and the node information is recorded to obtain the node control parameter set, so it can be seen that the node control parameter set is the front-end parameter drawn in the blank webpage.

S2. Generate a link type legend set corresponding to the node control parameter set according to the link type of the topology data set.

In detail, the S2 can refer to the detailed implementation flow diagram in Figure 3, including:

S21. Count the link type arrays corresponding to different node IDs in the topology data set to obtain the original link type array set;

S22. Remove duplicate link type arrays in the original link type array set to obtain a standard link type array set;

S23. Generate the link type legend set according to the number and array of the standard link type array sets.

For example, in the above-mentioned network device topology data set, including workstation topology data, switch topology data, router topology data, and server group topology data, respectively count the link types corresponding to workstation nodes, switch nodes, router nodes, and server group nodes array to get the original link type array set.

Further, the link type array can adopt multiple representation forms. In simple terms, for example, the link type array of the workstation node is [(w, 530, 2)], and the link type array of the switch node is [(530 ,w,2), (530,2621,2)], where w represents the workstation node, 530 represents the switch node (named after the model of the switch node), and 2621 represents the router (similarly, 2621 is the router model), because (w ,530) and (530,w) essentially represent the link between the workstation node and the switch node, which are removed because of repeated representation, and then the standard link type array set is obtained. It should be further explained that the number 2 It means that there is data transmission between the switch node and the workstation node. The number 0 means that the former node transmits data to the latter node, and 1 means that the latter node transmits data to the former node.

Specifically, a link type legend library may be pre-built, and a link type legend is selected from the link type legend library to generate the link type legend set according to the number and array of the standard link type array sets. The legends in the link type legend library are all composed of graphic symbol data and type name data. The graphic symbol data can be represented by different sizes, colors, and shapes, so that users can distinguish and identify different legends. To distinguish, the type name data is displayed correspondingly according to the difference between nodes. Specifically, for the representation form of the graphic symbol data and type name data in the topology map, please refer to the example diagram of the legend in FIG. 4 .

S3. Analyzing the link connection relationship and the link endpoint type between each node in the node control parameter set to obtain a link connection line set and a link endpoint type set respectively.

S31. Select two nodes without repetition from the node control parameter set to obtain a first node and a second node;

S32. Query the link type arrays corresponding to the first node and the second node respectively in the topology data set, to obtain a first link type array and a second link type array;

S33. Determine whether there is overlap between the first link type array and the second link type array;

S34. If there is no array overlap between the first link type array and the second link type array, re-select two nodes in the node control parameter set without repetition;

S35. If there is overlap between the array of the first link type and the array of the second link type, generate link connection lines and link endpoints according to the overlapped data of the arrays, when the node control parameters After the selection of all the sets is completed, all link connecting lines are collected to obtain the link connecting line set, and all link end points are collected to obtain a link end point type set.

The judging criteria for said data coincidence will be based on the different forms of the link type arrays and set the corresponding judging criteria, such as the link type array of the workstation node is [(w, 530, 2)], the link type array of the switch node is [(w, 530, 2)]. It is [(530,w,2), (530,2621,2)], because (w,530) and (530,w) essentially represent the link between the workstation node and the switch node, and the number 2 are the same, so the link type array of the workstation node and the link type array of the switch node have data overlap at (530,w,2), so it is known that the data overlap of the workstation node and the switch node is (530,w, 2), further split the (530, w, 2), such as splitting (530, w, 2) into (530, w) and (2), where (530, w) represents the workstation node and The switch node needs a link connection line, and (2) indicates that the workstation node and the switch node are in the form of link endpoints that exchange data with each other.

S4. Select a legend set corresponding to the link connection line set and the link end point type set from the link type legend set, use the front-end network topology drawing technology and control according to the legend set and the node The parameter set draws a topology map of the topology dataset.

If there are a large number of link connecting lines between the nodes, it is difficult for the user to quickly and accurately identify the relationship information of the topology map when faced with a large number of intertwined link connecting lines. Therefore, the first node and the second The link connecting lines of the two nodes are all single connecting lines, such as the above (530,w) indicates that the workstation node and the switch node need a link connecting line, (2) indicates that the workstation node and the switch node are the link endpoints for mutual data exchange form, and then select a link type legend corresponding to (530, w, 2) from the link type legend library without repetition, such as the link connecting line is a thick line and blackened, and the link end point is an arrow And the link connection line is in the form of double arrows, and the drawing is completed in the pre-built blank topology map according to the above-mentioned HTML5, Web-based JGraphx, echarts and other network topology map drawing methods.

Further, the link type array can adopt multiple representation forms. In simple terms, for example, the link type array of the workstation node is [(w, 530, 2)], and the link type array of the switch node is [(530 ,w,2), (530,2621,2)], where w represents the workstation node, 530 represents the switch node (named after the model of the switch node), and 2621 represents the router (similarly, 2621 is the router model), because (w ,530) and (530,w) essentially represent the link between the workstation node and the switch node, which are removed because of repeated representation, and then the standard link type array set is obtained. It should be further explained that the number 2 It means that there is data transmission between the switch node and the workstation node. The number 0 means that the former node transmits data to the latter node, and 1 means that the latter node transmits data to the former node.

It is [(530,w,2), (530,2621,2)], because (w,530) and (530,w) essentially represent the link between the workstation node and the switch node, and the number 2 are the same, so the link type array of the workstation node and the link type array of the switch node have data overlap at (530,w,2), so it is known that the data overlap of the workstation node and the switch node is (530,w, 2), further split the (530, w, 2), such as splitting (530, w, 2) into (530, w) and (2), where (530, w) represents the workstation node and The switch node needs a link connection line, and (2) indicates that the workstation node and the switch node are in the form of link endpoints that exchange data with each other.
