The Design And Realization Of The Software Scheme Of The Network Performance Tester Based On TRDP

With the rapid development of the network,the demand for network devices has also increased.The detection of network performance and the troubleshooting of network failures have become increasingly important.Therefore,it is of great significance to develop a high-performance,customizable network performance tester.With the increase of the data volume of train communication equipment,the traditional train network cannot support the increasing data volume,so the train Ethernet supporting big data transmission is a development trend.The Train Real-time Data Protocol(TRDP)is applied to train real-time Ethernet to ensure the real-time and reliability of its transmission.Therefore,it will be very important for the network performance tester to have the TRDP test function.This article mainly completes the design and implementation of software design of network tester based on TRDP.It first introduced the network performance tester related network protocols,specifically Ethernet frame protocol,IP and UDP.The train Ethernet and TRDP protocol testing guidelines are introduced,which lays a theoretical foundation for the network performance tester TRDP module.Afterwards,the overall architecture of the network performance tester was put forward as host computer software,embedded system and programmable logic device,and its performance advantage was analyzed.Then according to the functional requirements,the design steps and implementation methods of the tester TRDP module are analyzed.Finally,the TRDP module of the designed network performance tester is used for conformance testing to test the performance of the simulated train terminal equipment.The test results show that the function of the network performance tester TRDP module meets the design requirements and has a wide range of application prospects.
