【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。更多还原

【Abstract】 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 dis- advantages. Therefore, when deciding which one should be chosen for practical applications, situations of real environment must be taken into consideration.更多还原
