In order to ensure the real-time transmission requirements of the network and improve the success rate of scheduling,an Audio Video Bridging(AVB)stream routing and scheduling algorithm with real-time perception is proposed to simulate the AVB stream transmission in the scenario of vehicle-mounted Time-Sensitive Networking(TSN),and the influence of the proposed algorithm on the success rate of network scheduling is analyzed.The experimental results show that with the increase of the number of data flows,compared with the non-real-time perception algorithm and some real-time perception algorithms,the AVB flow routing and scheduling algorithm with real-time perception increases the success rate of network scheduling by 26%and 11%respectively,and the algorithm can optimize the bandwidth reservation of AVB flow in the TSN network and realize the real-time perception of data flow routing and packet information.
