摘　　要：针对已有基于单芯片交换结构的单组播集成调度算法在高速链路环境下无法在一个时隙内完成一次调度的问题,提出了一种支持单组播集成调度的并行分组交换结构UMSPPS(Uni-and multicast supported parallelpacket switch)。通过动态地调整单播平面数和组播平面数,UMSPPS可以支持任意比例的单组播混合业务。仿真结果表明,在各种比例的单组播业务情况下,UMSPPS的时延总是低于FILM和f SCIA,并且具有最优的总体吞吐率。As most existing integrated Uni-and multicast scheduling algorithms which were based on single chip,could not accomplish scheduling once within one time slot,proposed a UMSPPS architecture.By dynamically changing the number of switches that were used to switch unicast traffic and the number of switches that were used to switch multicast traffic,UMSPPS could deal with any mix of Uni-and multicast traffic.Simulation results show that the average delay of UMSPPS is always lower than that of FILM and f SCIA,and the overall throughput of UMSPPS is also the best.
