建立了访问方式为“循环策略”的高速数据总线网络的性能分析模型，消息的到达假设为Ｐｏｉｓｓｏｎ过程，在各站的信包到达率相同的情况下，根据随机过程的理论导出高速数据总线网络的性能参数令牌循环时间Ｔ的均值和方差的一般解析表达式，分别求出了消息长度为常数、Ｅｒｌａｎｇ分布、二项分布和Ｒａｙｌｅｉｇｈ分布的解析表达式。同时根据排队论的理论进一步分析了平均消息延时和平均消息长度。
The performance analysis model of high speed data bus network with access method as “cycle strategy” is established. The arrival of the message is assumed to be the Poisson process. Under the condition of the same arriving rate of each station, the high speed data bus network is derived according to the stochastic process theory The general analytical expressions of the mean and variance of the performance parameters of token tokens are obtained, and the analytical expression of message length is constant, Erlang distribution, binomial distribution and Rayleigh distribution respectively. At the same time, according to the theory of queuing theory, the average message delay and average message length are further analyzed.
