摘　　要：交换结构是交换机的核心,决定着交换机的性能。MSM型Clos交换结构是一种高性能交换结构,为有效仿真分析该交换结构建立了一种OPNET仿真模型。该模型将交换系统抽象为一个星型网络,其边缘节点对应交换结构输入和输出,中心节点对应MSM型Clos交换结构;并使用此模型仿真分析了3种典型算法的性能。该模型为交换结构性能的仿真分析提供了一种有效途径。Switching fabric is the core of switch and determines the performance of switching system. MSM Clos switching fabric is a high performance switching fabric. In order to analyze and simulate the switching fabric efficiently, a simulation model is presented with OPNET. Switching system is modeled as a star network in which the center node and periphery node correspond to MSM Clos switching fabric,and input/output respectively. The performance of three classical algorithms is simulated with the model which provides an efficient approach for simulation and analysis of the performance of switching fabric.
