Research And Implementation Of Modeling Tool Of Computer Network Structure Based On MxGraph

With the systematic development of the global space infrastructure,my country's civil infrastructure construction has entered a new developing stage.On the basis of the national "Twelfth Five-Year Plan",in October 2015,the related national department issued the "Mid-and Long-term National Civil Space Infrastructure Plan(2015-2025)".According to the national policies and requirements for the construction of terrestrial observation satellite ground systems,the National Civil Space Infrastructure Terrestrial Observation Satellite Common Application Support Platform Project was launched on January 26,2018."Single-Ground Synchronization Data Simulation Software"(hereinafter referred to as "simulation" "Project")is an extension of the common application support platform.The simulation project is a large-scale distributed application system,and its working environment depends on computer local area network(LAN).This research is to better show the network structure of the remote sensing simulation project working environment,and to support the comprehensive evaluation of its operating environment performance in the future.In order to meet the needs of the simulation of the simulation project working environment,this paper studied and implemented a general-purpose network structure visual modeling platform based on the workflow model.The main contents are as follows:(1)Build relevant data models for network structure visualizing.By researching the attribute characteristics and data storage structure of the network equipment,the data model and component model of network structures equipment components are designed to prepare for the network structure visualization scheme realizing.At the same time,the realization scheme of the network device connection relationships and the network topology storage structure is proposed,and the identification problem of the same network device that appears many times in the process of modeling the network structure was solved.(2)Design a computer network structure modeling system.Based on the user's demand for the online construction of the simulation project network environment,network structure modeling realization scheme is designed.At the same time,the composition of the network structure is decomposed into equipment and equipment parts,and the equipment unit is the smallest unit.The equipment component parameter entry strategy of the system is designed to provide data support for the reuse of network structure modelingprocess parameters.(3)Integrate the web framework Vue with the mxGraph process engine.The mxGraph core code base is referenced,and mxGraph is compatible and adapted.For many methods in mxGraph,a second packaging and transformation were carried out to make it better to interact with the Vue template engine.It also provided solutions for operations such as dragging,connecting,zooming,cutting,copying,and personalized parameter configuration and binding of network device components.(4)A computer network structure modeling system was realized.According to the needs of the comprehensive analysis and simulation system for remote sensing products,this article is applied to computer network structure modeling tools development,which verified feasibly and layed a foundation for the later network system performance evaluation.Practical applications showed that the data model and visualizing components designed by this system could display various complex network structures and device information.At the same time,the system has rich functions,convenient operation,and beautiful interface.Users can quickly build a network structure by dragging and dropping with the mouse Figure,greatly improving efficiency.
