Abstract:
According to the train communication network and multifunction vehicle bus network realtime transport protocols, the authors presented a dynamic priority roundRobin algorithm. Multifunction vehicle bus (MVB) is used widely in train communication networks to realize interconnection among different devices. It must meet the realtime performance while multifunction vehicle bus is used to transmit data according to the ICE613751. In the multifunction vehicle bus network, the delay among transmission equipments mainly includes waiting to be sent delay and transmitting the data packet delay and so on. Based on the priority of nonperiodic data to achieve arbitration scheduling, the algorithm can improve the realtime performance of multifunction vehicle bus network to transmit the nonperiodic data by means of optimizing the complexity of algorithm and reducing waiting delay and blocking delay. The simulation analysis shows that the algorithm can improve the realtime performance and fairness performance of MVB transmission. At the same time, the algorithm also meets the requirements of the ICE61375-1.
Key words: multifunction vehicle bus (MVB), nonperiodic data, round Robin algorithm, realtime performance
