对一种交换网络阻塞概率的计算

The Blocking Rate of a Switched Network

本文对当前国产交换机普遍采用的一种全分散，模块化的交换网络的阻塞概率进行了分析。这种交换网络由许多独立的交换模块与一个中央交换模块构成。文中指出了网络阻塞概率的三个来源，并着重对第三个来源进行了定量分析。另外我们还根据分析结果给出了在现有技术条件下。

An architecture of a generally used switched network is described and the blocking rate of this architecture is analysised in this paper. This switched network is composed of a central module and some independent switched modules. The sources of the blocking rate is pointed out and the third part is analysised mathmaticly. The capacity of the network is given using the obtained result.
