摘　　要：交换结构与调度策略对于核心路由器的性能及网络业务流的QoS保证具有重要的意义。基于目前流行的带缓存交叉开关交换结构(CICQ),采用系统级设计方法和面向对象技术,设计并实现了用于研究基于带缓存交叉开关构建的交换结构与调度策略的仿真平台-SPES。设计上实现了业务流、交换结构和调度策略三者之间的分离,具有良好的可继承与可扩展性。最后给出了在该平台下,CICQ流行调度策略的仿真结果,展示了SPES的优良性能。Switching fabrics and scheduling policies play significant roles in guaranteeing performances of core routers and assured QoS （Quality of Service） for different traffic in today＇ s internet. Based on current buffered crossbar switching fabric, by employing system level design method and objective oriented technology, we design and implement a simulation platform for switching fabrics and scheduling policies＇ development. Inheritability and extensibility attributes are obtained by designing traffic sources, switching fabrics and management policies separately. Finally in this article, we present some simulation results for existing scheduling policies, displaying the good performances of our platform.
