【摘要】 假设交换网络的流入话务为Ｐｏｉｓｏｎ流分布，呼叫的保持时间为指数分布，本文提出一种新的电路交换话务模型．利用聚合分散的解析方法求解该模型，推导出在一般路由计划下流入话务量与呼损率之间的关系式，并对无迂回路由的网络流量进行了分析．更多还原

【Abstract】 Under the assumptions of Poisson distribution for offered traffics and exponential distribution for holding times,this paper presents a new traffic model for circuitswitched networks.The relationship between traffic intensity and loss probability has been derived for general routing policies by means of aggregationdisaggregation analytic method,and the network without alternate routing is analyzed and discussed in this paper.更多还原
