摘　　要：对IEC61375-1规定下的MVB总线网络通信方式进行了研究,提出了MVB总线网络动态性能的衡量指标为协议效率、网络效率、网络有效利用率、网络吞吐量等,并推导出了各项指标的计算公式,通过仿真模型实例计算评估了不同通信介质和负载对MVB总线网络的动态性能的影响。The MVB communication network system which obeyed to IEC 61375-1 standard was researched in this article. The measurement index of MVB network dynamic performance including protocol efficiency, network efficiency, network utilization and network throughput was put forward and the relevant formula on the index was derived in the context. With a simulation example, impact of various communication medium and load on MVB network dynamic performance was evaluated and analyzed.
