摘要: 分析了一般高速数据总线HSDB网络中消息延时控制的机理;根据不同优先权的网络吞吐量导出了一般HSDB网络设置4个定时器(1个令牌握有定时器(THT)和3个令牌旋转定时器(TRT))的解析表达式,为用户应用HSDB网络设置THT和TRT提供了理论参考依据。

Abstract: In order to control message delay,high speed data bus (HSDB) provides four priority classes,which are implemented by four timers (one token holding timer (THT) and three token rotation timers (TRT)). If a station wants to control message delay for different priority,in fact,the objective is to allocate network bandwidth among different priority levels by the four timers. The principle of message delay control for a general HSDB network is analyzed,and according to the network throughput of each priority level the anatytical expressions for setting the four timers in the general HSDB network are derived. The results provide the basis of theoretical reference for setting THT and TRT in the HSDB network.
