| 摘 要： | 对令牌传递网络按优先级传输消息的机制进行了分析,提出了一种新的令牌旋转定时器初值的计算方法,该方法使网络消息依最大允许的延迟时间从小到大排序,并在一定网络负载下保证所有消息传输的实时性.本算法得出的结果与国外较成熟的工程实例相比有相当的精度,证明本文的分析和算法是合理有效的.

| Abstract: | The transmission mechanism of the messages with their priorities for token passing networks was studied.A new method to determine the value of token rotation timers is proposed,which makes messages to be transmitted according to their maximum allowable latency sizes,from small to big,and meets all the message latency requirements under certain network load.Results of our algorithm have considerable precision comparing to outcomes of method presented in LTPB design handbook,which validates that our analysis and algorithm is practical. |
