| 摘 要： | 基于广义随机Petri网(GSPN)，对数字交换机面临过载时的一种阻塞呼叫控制机理进行了描述与分析，建立了其广义随机Petri网模型。通过对模型求解、构造可达图及同构Markov链，推导出了这种控制方式下系统性能的解析结果，给出了它们与控制严密程度之间的关系，从而为定量分析和评价数字交换机过载控制特性提供了依据。

| Abstract: | Based on Generalized Stochastic Petri Net (GSPN), a blocking call controlscheme, when digital exchanges facing overload, is described and analyzed. The GPSNmodel of the exchanges is built. By finding the solution to the model and constructing itsreachability graph and homogeneous Markov chain, the analytic results of the systemperformance under this control scheme are obtained. The relationship between performanceindex and control restriction is given. All this can provide a basis for quantitative analysisand evaluation of overload control property in digital exchanges |
