Detailed Description
The embodiment of the specification provides a method, a device, equipment and a medium for generating a topological graph of network equipment.
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present specification without any creative effort shall fall within the protection scope of the present specification.
Fig. 1 is a schematic flowchart of a method for generating a topology diagram of a network device according to one or more embodiments of the present disclosure, where the process may be executed by a related platform for generating a topology diagram of a network device, and the platform may be applied in different development environments, and when a network environment is built, a topology diagram structure of a network device is generated, so as to facilitate visual display of an association relationship of a virtual network. Certain input parameters or intermediate results in the flow allow for manual intervention adjustments to help improve accuracy.
The method of the embodiment of the specification comprises the following steps:
s102, when a network environment is built, a switch node built in the network environment in advance and a configuration node corresponding to the switch node are obtained;
in this embodiment of the present disclosure, before obtaining a switch node and a configuration node corresponding to the switch node that are constructed in the network environment in advance, a configuration corresponding to a switch and a switch in the network environment may be obtained first, and then, the configuration corresponding to the switch and the switch is encapsulated by a JTopo plug-in to construct the configuration node corresponding to the switch node and the switch node.
The JTopo plug-in is a plug-in for drawing a topological graph, and the plug-in uses H5 Canvas to draw elements and operate the elements, so that the graphical processing of the dependency relationship of data can be realized.
S104, determining the subordination relation between the switch node and the configuration node, the subordination relation between different configuration nodes and the type of the configuration node.
In this embodiment, the configuration corresponding to the switch may include a firewall, a load balancing node, a subnet, and an IP address, and the types of the configuration nodes include a firewall node, a load balancing node, a subnet node, and an IP address node.
It should be noted that, the subordination between the switch node and the configuration node, the subordination between different configuration nodes, and the type of the configuration node are all preset, and this description embodiment may directly obtain, for example, the subordination between the switch node and the configuration node may be the firewall node b, the load balancing node c, and the subnet node d, the configuration node corresponding to the switch node a may be the firewall node b, the load balancing node c, and the sub-ordination between different configuration nodes may be the subnet node e, the IP address node f, and the IP address node g corresponding to the subnet node d.
And S106, determining the layer number of the switch node and the configuration node in the topological graph according to a preset layer number placing rule and the type of the configuration node.
Further, when the number of layers of the switch node and the configuration node in the topology graph is determined according to a preset number of layers placement rule and the type of the configuration node, the number of layers of each type of node may be set according to the preset number of layers placement rule, and in this embodiment of the present specification, the load balancing node and the firewall node may be placed on the first layer of the topology graph, the switch node is placed on the second layer of the topology graph, the subnet node is placed on the third layer of the topology graph, and the IP address node is placed on the fourth layer of the topology graph.
It should be noted that, the number of layers of the switch node and each configuration node in the topology diagram is not limited to the above manner, and the address node, the subnet node on the second layer, the switch node on the third layer, and the firewall node and the load balancing node on the fourth layer may also be placed on the first layer of the topology diagram.
The embodiment of the specification can directly determine the number of layers of the switch node and the different types of configuration nodes placed in the topological graph through the layer number placing rule without manual classification, so that a large amount of manpower can be saved. After the number of layers of the switch node and the different types of configuration nodes placed in the topological graph is determined, the subsequent steps can be executed to determine the specific positions of the switch node and the different types of configuration nodes.
S108, determining the positions of the switch and the configuration nodes in different layers of the topological graph according to a preset position placing rule, the subordination relation between the switch node and the configuration nodes and the subordination relation between different configuration nodes;
in this embodiment of the present specification, a coordinate value of the switch node may be set first, where a position of the switch node may be set arbitrarily, and after the position of the switch node is determined, the position of the configuration node is determined based on the switch node; then, coordinate values of the configuration nodes can be determined in different layer numbers of the topology map according to preset position placing rules, coordinate positions of the switch nodes, the subordination relationship between the switch nodes and the configuration nodes, and subordination relationships between different configuration nodes. Because the number of layers of the switch nodes and the configuration nodes in the topological graph is determined in the steps, when the position of each configuration node is determined, each configuration node is arranged around the switch node only by depending on the subordinate relationship between the switch node and the configuration node and the subordinate relationship between different configuration nodes, and the position arrangement rule at the moment can be used for orderly arranging each configuration node according to a sequencing algorithm and a recursion algorithm.
And S110, connecting the switch with the determined placing position with the configuration node according to the subordination relationship between the switch node and the configuration node and the subordination relationship between different configuration nodes to obtain a network equipment topological graph.
After the network device topology map is obtained, if the position of the switch node or the configuration node is misaligned, after receiving the moving instruction, the embodiment of the present specification moves the switch node or the configuration node, which is misaligned, to the designated position, and updates the corresponding coordinate value.
In the process of building a network environment, a plurality of switches are configured, a firewall, load balancing and the like are configured for the switches, subnets are configured under the switches, then IP addresses are distributed, and configuration information of the switches needs to be checked through an intuitive interface. When the network fails, the network topological graph can be quickly checked to show the configuration information of the switch.
Referring to a schematic diagram of a topology generation manner of a network device shown in fig. 2, in an overall flowchart of an embodiment of the present specification, at the beginning, a firewall of a switch, load balancing, and subnet information are stored in a database, then, a visualization algorithm program generates available data, then, a network request is performed, device data is analyzed, then, a topology is drawn according to node data, a flow is ended, and if a problem occurs when the device data is analyzed, a front end exception prompt is given, and the flow is ended.
The internal implementation mechanism of the embodiments of the present specification can be implemented by the following detailed steps:
when a network environment is built, the background stores equipment information such as a switch, a firewall, load balancing, a subnet and an IP to a database, the equipment information comprises equipment type and equipment subordination, then the equipment information is issued to a visualization program, in the visualization program, effective data is generated according to an algorithm formula on the equipment type and the equipment subordination, and finally the effective data is formed and stored in a warehouse. The visualization program generates effective data of a multi-branch tree linked list structure according to a sorting algorithm and a recursion algorithm, finds a top parent node as a first node of the multi-branch tree, and calculates the type, coordinate point and connecting line direction of each node. And performing view rendering by using a web visualization technology to generate a topological graph.
Js, CSS, draw graphics using Canvas, an API provided by Javascript, draw 2D graphics through < Canvas > tag elements. And (4) using the unique id of the device as a node of the topological graph, and initializing the position of the node according to x and y coordinates returned by the background. And generating a connecting line between the nodes according to the linkId and the destNode, and setting corresponding icons according to different equipment types. When drawing the graph, the graph is sequentially arranged by taking the switch as a unit, the first layer is load balancing, firewall and routing information, the second layer is the switch, the third layer is a subnet, and the fourth layer is IP information. The node supports clicking to check details and dragging. When the node is dragged, the node coordinate is stored and is stored in a background, and the real-time performance of the position coordinate is guaranteed. The topology map panel supports operations of zooming in, zooming out, full screen, adaptive canvas, and the like. Through the topological graph, the configurations of the firewall, the load balance, the subnet, the IP and the like of each switch can be clearly seen.
With the adoption of the scheme, the obtained topological graph has a display effect schematic diagram, as shown in fig. 3, wherein the first layer is the firewall node and the load balancing node respectively, the second layer is the switch node, the third layer is the three subnet nodes corresponding to the switch, and the fourth layer is the IP address nodes corresponding to the subnet nodes respectively.
Further, regarding that a node supports click-to-view details, reference may be made to a first schematic diagram and a second schematic diagram of a display effect of topology details shown in fig. 4 and fig. 5, and in a topology diagram, in this description, device configuration information may be clicked and viewed, that is, virtual device details are displayed on the right side.
When a network environment is built, the configuration corresponding to the switch and the switch is set as the corresponding switch node and the configuration node, and the switch node and the configuration node are generated into a topological graph according to the subordination between the switch and the switch configuration, the subordination between different switch configurations and the type of the switch configuration, so as to visually display the associated topological information between the switch and the switch configuration.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain a corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical blocks. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
As will be appreciated by one skilled in the art, the present specification embodiments may be provided as a method, system, or computer program product. Accordingly, embodiments of the present description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, embodiments of the present description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and so forth) having computer-usable program code embodied therein.
The description has been described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flowchart illustrations and/or block diagrams, and combinations of flows and/or blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions.
