| 摘 要： | 在分析阻塞呼叫控制机理的基础上，用广义随机Petri网(GSPN)对数字交换机中另一种常用过载控制机理——延时呼叫控制，进行了描述与分析，建立了其GSPN模型。通过对模型求解，得出了采用控制后系统性能的解析表达式，以及与控制严密程度之间的关系，从而定量分析并评价了这种控制机理的控制特性。最后，对两种控制机理的结果进行了比较。

| Abstract: | Based on blocking call control scheme, another overload control scheme called de-laying call control is described and analyzed using generalized stochastic Petri networks(GSPN) with its model construction. By solving the model, the analytic formula of the sys-tem performance under this control, the relationship between performances indexes and con-trol strictness are obtained. The overload control property can be analyzed and evaluated in aqualitative way. Finally the results of the two control schemes are compared with each oth-er. |
