Design And Implementation Of Topology Module Of Routing Visualization System

With the continuous advancement of China's information construction and the rapid development of the Internet economy,the scale of the domestic Internet network has grown greatly,and the network structure has become increasingly complex and frequently changed.The more complex network put forward higher requirements on the maintenance and operation of operators,and operators need to provide higher quality network services to users.Since the maintenance methods used by network operators in the past are cumbersome and inefficient,and require high skills of maintenance personnel,they are no longer able to meet the current demand for efficient response to large and complex networks.To address this problem,this paper designs and implements a topology module of the routing visualization system,provides the ability to visually monitor and manage the network topology,and help improve the efficiency of operators' maintenance personnel.The topology module of the routing visualization system introduced in this paper is divided into four main sub-modules: topology display,topology monitoring,topology playback,and path simulation.The topology display sub-module implements a three-layer topology structure based on rule definitions,which quickly forms a hierarchical topology diagram that meets the requirements through customized rules for visual display.The topology monitoring sub-module realizes real-time monitoring of network status information and network structure change information on the network topology diagram.The topology playback sub-module provides the display of the historical structure changes of the network topology diagram,and supports the dynamic playback and display of the historical changes of the network topology.The path simulation sub-module realizes the calculation and display of the shortest path between the devices of the network topology diagram,and supports the modification of the structure of the network topology by setting the simulation conditions,and then calculates and displays the shortest path between the devices under the simulation conditions.This paper introduces the background significance of the development of the topology module of the routing visualization system,analyzes the requirements of each submodule,specifically elaborates the structure of the topology module and the detailed design and implementation of each sub-module,and conducts functional and performance tests on the topology module.The development of the topology module uses the design mode of separating the front and back ends.The front end is developed using the Vue.js framework,the Easy UI framework and the ZRender framework,and the back end is developed using the Spring Boot framework.This topology module has been put into use by network operators in some provinces,and has played a good role in helping network maintainers to improve their work efficiency.
