摘　　要：本文对线性令牌传递网络（ＬＴＰＢ）的实时特性进行了研究，提出了与节点负载匹配的网络带宽分配方法，导出了在该方法下网络消息集严格实时的充要条件，导出并证明了即使在最坏情况下消息集严格实时的网络可达负载率不小于５０％。This paper studies the real time characteristics with LTPB network. A bandwidth allocation scheme is proposed based on the traffic load balance of each node. The necessary and sufficient conditions of guaranteeing message deadlines under the allocation scheme has been derived. The bounds of the Worst Case Achievable Utilization for the scheme has also been derived and formally proved.
