摘要
多功能车辆总线MVB需要传送具有高实时性要求的周期信息和随机到达的非周期信息,合理分配相应信息带宽可以提高整个网络的通信带宽利用率。在分析各类信息特点的基础上,提出了非周期信息通信的两种带宽分配策略。结合MVB非周期信息的调度方法,对两种策略进行了分析研究和性能比较,给出了各种策略的适用范围。
Both periodic and aperiodic messages are transmitted on multifunction vehicle bus （MVB）. The transmission of periodic messages must comply with the strict real-time requirements and aperiodic messages are always made a random arrival. Bandwidth availability of MVB can be improved if the bandwidth is distributed reasonably. On analyzing the characteristics of every type of messages, two bandwidth allocation strategies of MVB aperiodic communication are proposed. In combination with the scheduling principles of aperiodic messages, the two bandwidth allocation strategies are researched and compared; the application scope of every strategy is given.
