提出了一般令牌网络的性能分析模型．在模型中，访问方式为“循环策略”，消息包到达各站点服从Ｐｏｉｓｓｏｎ分布，消息包到达率不完全相同，消息包长度既有常数也有负指数分布．根据随时过程的理论导出了令牌循环时间Ｔ的均值和方差的一般解析表达式，同时应用排队论的方法进一步分析了平均消息延时、平均消息长度和逻辑环路利用率． Proposed a general token network performance analysis model. In the model, the access method is “round robin strategy”, the packets reach Poiss distribution at each site, the packet arrival rates are not exactly the same, and the packet length has both constant and negative exponential distribution. According to the theory of contingency process, the general analytic expressions of the mean and variance of token cycle time T are derived. Meanwhile, the average message delay, the average message length and the utilization of logic loop are also analyzed using queuing theory.
