典型ATM交换机缓冲系统在类C/S业务模式下的队列长度比较

Comparison of Queue Length in Typical ATM Switch Buffering Systems under the Traffic Similar to C/S Model

许多应用场合中的通信业务可以用类用户一服务器（C／S）业劳模式来表达，因此有必要研究这种业务下的ATM交换机缓冲存储器策略；本文以计算机仿真的手段评估了四种典型缓冲结构的队列长度概率分布情况，进而比较了类C／S业劳模式下ATM交换机几种典型缓冲系统的性能。

The communication traffic in many cases can be expressed with a model sim-ilar to client-server (C/S) traffic. Therefore it is necessary to study the buffer tactics forATM switches under such kind of traffic. This paper evaluates the probability distribution ofqueue length for four kinds of typical buffer fabric with the help of computer simulation, andthen compares the performance of several typical buffer systems for ATM switches underthe traffic similar to C/S model.
