Development Of Time Sensitive Network Management Software

The Time Sensitive Network(TSN)proposed by the IEEE802.1 task group in 2012 can provide certainty and reliability for data frame transmission on Ethernet due to the characteristic of low deterministic delay.To some extent,it solves the deficiency of reliability and real-time performance of current Ethernet in industrial control,automatic driving,robot and other fields,and has become the prototype of future industrial Ethernet.But at the same time,with the increase of network reliability and real-time,network protocols become more and more complex,and network configuration has higher demands on data structure,on-demand planning,automation,compatibility,interoperability,security,and other aspects.How to realize efficient network management becomes the key to upgrade network service technology.At present,the demand for the application of TSN is also increasing,and the development of communication equipment based on TSN has also become the current hot direction.The main research direction of this paper is the development of TSN network management software.The main contents of this paper are as follows:1.Study and analyze the 802.1Qcc protocol,802.1AS protocol,802.1Qbv protocol,802.1Qci protocol and 802.1CB protocol in the TSN protocol cluster,and study the configuration management scheme of the above protocols through SDN.The feasibility of three user/network configuration models proposed by IEEE802.1Qcc protocol is studied.2.Study the overall architecture of TSN network management software system and design a highly reliable configuration system scheme that meets centralized control and management with the target of user distributed model.Secondly,the hierarchical design of the system is carried out to complete the specific design of the three key modules of the software system,namely the upper computer,the server and the lower computer,and the communication architecture model of each module is given.3.Use the NETCONF protocol based on extensible markup language XML and the YANG model language to model the configuration data of many protocols in the TSN protocol cluster.Use Linux QT software to complete the development of the upper computer of the configuration system and the Linux system programming of the switch hardware core board based on ZYNQ chip.Build the cross-compilation environment,complete the configuration of the system’s lower computer and driver development,and finally realize a set of TSN network management system.4.The function test of the upper computer software and the lower computer software modules of TSN network management system.TSN network entity test environment was built on site,and software system operation test and node configuration test were completed.Summarize the reliability problems of NETCONF protocol in configuration and propose solutions.
