Research And Design On Configuration Schem Of Time-sensitive Networking System

With the rapid development of information and communication technology,network equipment is required to have high real-time and high reliability characteristics.Based on the above requirements,the IEEE 802.1 Working Group has proposed relevant standard protocols for Time-Sensitive Networking(TSN).TSN is a deterministic network that can provide low-latency transmission and ensure communication bandwidth,that is,it can guarantee the certainty and reliability of end-to-end communication.At the same time,with the network becoming more and more complex and network equipment becoming more and more numerous,the problem of whether the network configuration is convenient and accurate has become more and more prominent.How to improve the efficiency and accuracy of the configuration has become the key to speed up and upgrade the network services.TSN network configuration is similar to the configuration of other common network equipment and network services,which are faced with many configuration parameters and low-level configuration language.At present,there are few researches on TSN system configuration technology at home and abroad.Therefore,this thesis mainly studies the scheme from the perspective of TSN system configuration technology,which is a new idea of TSN related technology research,and the specific contents are as follows:(1)The TSN system configuration is researched,and the TSN configuration system architecture and scheme are designed.The IEEE 802.1 Qcc protocol and TSN configuration model are mainly studied.Based on the fully centralized model,a TSN configuration system is designed to meet the requirements of centralized control management,high reliability and automatic implementation.The scheme can use a small number of collected configuration behavior parameters for automatic RPC modeling,generate abstract configuration files that can be identified by devices,and automatically deploy them to TSN devices after routing calculation and parameter verification.In addition,the hierarchical system architecture design and the concrete design of two key modules,the centralized user management CUC and the centralized control management CNC,are given.(2)The TSN configuration system is implemented.Combined with Network Configuration Protocol(NETCONF)and YANG data modeling language,a configuration system for switch equipment integrated with TSN network is realized by using fr-ont-end code encapsulation and joint debugging technology.In addition,the traditional configuration method requires administrators to configure devices one by one,which cannot meet the needs of multi-node configuration in industrial application scenarios.This system encapsulates and implements a universal monitoring and identification module,a configuration data processing module and a configuration information deployment module.(3)The function of TSN configuration system is verified by testing,and the system scheme is compared with the Command Line Interface(CLI)used by NXP to configure TSN.The system test environment is designed and implemented.According to the functions supported by the system,functional test cases are designed and compiled to verify the availability of system configuration functions.Compared with CLI configuration mode,it is proved that this system configuration scheme reduces configuration complexity,reduces repetitive configuration work and enhances the reliability of configuration management operation.To sum up,this thesis researchs TSN system configuration,designs TSN configuration system architecture and scheme,and designs and implements TSN configuration system.According to the system test verification results,it is proved that this scheme is feasible and effective,which is lower in complexity,more efficient and more reliable than the method of configuring TSN equipment by CLI.
