| China’s Internet has been continuously upgraded and upgraded,and there has been a significant improvement in the quality of network connectivity,the transmission of network data and the quality of network broadband.At the same time of improving quality,its traffic usage fee is decreasing,which greatly meets the needs of people in the information age for network transmission,and accelerates the arrival of next-generation Internet.IPv6 is the symbol of next-generation Internet technology,multi-path TCP protocol(Multipath TCP,abbreviated as MPTCP)Multipath transport technology is another milestone for the next generation of the Internet.The Hainan University campus network signed the CERNET2 platform in September 2016 to access the IPv6 network and encourage students to conduct innovative research on next-generation Internet technologies and application services to promote the development of the next generation Internet.In addition to mobile phones,network access devices are also increasing in variety and mode,making it possible to provide multi-homing terminals featuring multiple network interfaces to provide high-quality network services,such as the MPTCP protocol supporting multi-homing.The technology of the system,which can generate multiple paths between networked terminals and realize concurrent transmission.The MPTCP researched by this research group is an extension of the TCP protocol.It can support multiple paths established by multiple network interfaces and multiple access modes between terminals,that is,concurrent transmission and improve bandwidth utilization.In addition,when part of the transmission path fails,other paths can continue to provide network services,thereby improving the robustness of the connection between the terminals.After configuring the path management algorithm,MPTCP can selectively establish a transmission path and introduce a congestion control algorithm.The advantages of data transfer from the congestion path.Because MPTCP protocol has extraordinary significance in many key applications in the next generation Internet,it gradually reflects the practical value of MPTCP.This paper first introduces the main functions of MPTCP,and introduces the research team’s multiple functions of MPTCP,combined with the use of IPv6 in recent years,a large number of test scene data analysis and research,the research team used in the real Internet built test bedThe NorNet International Test Bed evaluates several functions of MPTCP and conducts test design and test analysis on the test bed.At present,the project team has carried out a lot of testing and research work on MPTCP on the NorNet test bed.It is completed by the command line of the terminal character interface.There are many operation steps,the command memory is difficult,and the input is cumbersome.In order to simplify the experimental research operation of the project team and promote the application of MPTCP technology,from the perspective of the experimenter,this project uses MPTCP as the research object,combined with multi-path international test bed and software development technology to build a multi-path transmission visual test platform based on IPv6.The theoretical knowledge and related technologies used in the platform are described,including development tools,architecture,workflow,and system testing.The platform adopts the B/S architecture,the development technology selects the JSP technology,realizes the visualization model through the Java program,and displays the specific experimental steps such as the script design and operation of the NorNet international test bed in the form of Web,and the client takes the browser to complete the operation..The integrated development tools used by this platform include MyEclipse,JSP,Tomcat,and Vim.They are implemented in conjunction with the MVC layered design pattern.They are mainly composed of multi-path transmission technology modules,site query modules,configuration scripts,and running modules,and have NorNet test bed sites.The resource information query,the configuration of the MPTCP performance test parameter visualization,and the visual representation of the test data enable the specific implementation steps of the test experiment to be visualized.In the system implementation,the module interface screenshot and part of the implementation code are presented,the operation flow is described,the test purpose and test case are given in the test,and the correctness of the visual test platform is verified.The platform for the design and implementation of this project has been put into normal operation.The platform can facilitate the project team to test the script design and parameter configuration of MPTCP research,reduce the learning cost of MPTCP and NorNet international test bed researchers,improve research efficiency,and standardize refinement work.Process and easy to maintain. |
