摘　　要：研究LTPB（线性令牌传递总线）通信网络中带宽分配方法对网络实时性能的影响,提出了一种优化的带宽分配方法和基于“最差情形下可达负载率”的网络实时性能分析方法,证明了该带宽分配方法优于所有传统的分配方法,最后举例说明了结论的正确性。Real-time performance in LTPB communication network is investigated under the effects of bandwidth allocation schemes. An optimal bandwidth allocation scheme (OLA) for LTPB network and an real-time performance analysis method based on WCAU(the worst available utilization) are proposed . Formal proof that OLA has better performance than any other schemes is given. Finally examples are given to demonstrate the correctness of the conclusion.
