摘　　要：针对当前高性能路由器普遍采用的多级多平面交换结构,对"push"和"pull"这两种最常用的调度机制进行了分析。通过搭建opnet平台对这两种调度机制进行了仿真对比,结果表明,两种调度机制各有优缺点,需要根据实际需求来选择合适的调度机制。This paper analyzes the ＂push＂ and the ＂pull＂ scheduling schemes, which are the most widely tech-nologies in current high performance routers with Multi-Plane Multi-Stage switch fabric. Simulation results on the comparison of these two schemes show that both of the two schemes have its own advantages and disadvantages. Therefore, when deciding which one should be chosen for practical applications, situations of real environment must be taken into consideration.
