Design And Implementation Of Management System Of Space-Earth Integrated Network Based On Identifier Mapping Protocol Stack

With the continuous expansion of the Internet,defects such as low security,poor mobility support,and poor scalability in the design of the Internet architecture make the current Internet architecture no longer suitable for the space-earth integrated network communication system.The Identifier-based network divides the network into network space and user space,which solves the shortcomings in the traditional Internet architecture,and it is very consistent with the autonomous security,manageable and controllable,reliable and stable,and on-demand transmission requirements of the space-earth integrated network.Because the space-earth integrated network based on the Identifier Mapping Protocol(IDMP)stack has a special network architecture and network protocol,the traditional network management system is no longer applicable to this network.The work of this paper is a part of the "Space-earth Integrated Network Based on the IDMP Stack" project,which aims to design and implement the network management system of the space-earth integrated network based on the IDMP stack.This thesis analyzes the application requirements of the space-earth integrated network management system based on IDMP stack,and designs a network management system based on the B/S architecture.To facilitate the deployment of multiple instances of network management system applications,the system has designed a stateless login authentication module for administrators.Aiming at the problem of limited satellite computing resources and bandwidth resources in the space-earth integrated network,in order to further reduce the consumption of network bandwidth resources used by the performance management module,the network performance management part is designed in detail in this paper.For the resources such as identifier mapping protocol,authentication and authentication protocol,and routing control protocol in IDMP stack,the network management system implements centralized management of the above resources by configuring multiple data sources in the user management and identity routing management modules.The paper realizes the network management system by modules.In the performance management part,cache technology is used to solve the problem of repeated performance query when there are too many users in the network management system,so as to reduce the occupation of network bandwidth by performance query.Through the Websocket Protocol,the full duplex communication between the user browser and the server is realized,avoiding the consumption of bandwidth resources of the network management server by HTTP polling.According to different application scenarios,the database storage part of the management system comprehensively utilizes the advantages of relational database and cache database,which not only solves the problem of data pollution caused by multithreading concurrency,but also improves the data storage capacity of the system.In the log module,we use the aspect oriented programming technology,which not only simplifies the code structure,but also increases the reusability of the code.Finally,the management system of space-earth integrated network based on IDMP stack was deployed in the laboratory environment,and the five functional modules of the system were functionally tested through the Postman test tool and the Web browser tool.The test results show that the network management system designed in this paper realizes the network management function.
