摘要
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.
A performance analysis model of general token-passing networks is presented in this paper. In the model,the networks are served with 'round-robin strategy',message package arriving at each station are assumed to be a Poisson process with different arrival rate and message package lengths are assumed to be both constant and exponentially distributied. Based on the theory of random process,the general analytic expressions for the mean and variance of token rotation time T are derived. Meanwhile, by applying queueing method, the mean message delay,the mean message lengths and logiC ring utilization are further analyzed.
