摘　　要：伴随着世界经济的快速发展,我国国内的经济形势也在日新月异的发生着变化,而网络的出现和更新更是无时无刻不在影响着我们的生活,同时,人们对网络存在的要求也逐渐变得更高。在因特网中的交换机,也就是所说的路由器现如今面临着两种挑战,一种是高交换速率的挑战,一种是联网服务质量(QOS)的挑战。高交换速率的挑战需要交换机/路由器尽可能的通过链路速率进行工作,联网服务质量(QOS)需要要求交换机/路由器可以完全仿效输出队列(OQ/output queuing)交换机的方式行为。到目前为止,联合输入输出队列(CIOQ/combined input-output queuing)的设计方案与交换机/路由器的不同,它需要交换机/路由器的内部速率加速到原有的2倍。为了满足这种技术的要求,重端口交换机(DPS/duplicated ports switch)的并行技术设计方案应运而生。这套方案有效证明了仿照交换机输出队列(OQ)的行为,以2为端口重数的必要充分性,并且这套方案的使用交换机/路由器可以工作在输入链路速率上,它的行为同交换机/路由器(OQ)的行为是等价的。With the rapid development of the world economy, China＇s domestic economic situation is also changing changing, and the emergence of the network and update all the time it is affecting our lives, at the same time, the presence of people on the network requirements are gradually higher.Switches in the Intemet, also known as the router is now faced with two challenges, one is to challenge the high exchange rate, one is the network quality of service（ QOS ）challenge.Challenges require high exchange rate switch / router as possible to work through the link rate, network quality of service （ QOS ） requirements need to switch / router can completely emulate the output queue （ OQ / output queuing ） switch mode behavior.So far, the joint input and output queue （ CIOQ / combined input-output queuing ） different designs and switch / router, it needs internal rate of switch / routers accelerated to the original two -fold.In order to meet the requirements of this technique, re -port switch （DPS / duplicated ports switch ） parallel technical design emerged.This program modeled switch proved effective output queue （ OQ ） behavior to two the number of ports necessary to resufficiency, and the use of this program switches / touters can operate on the input link rate, it behaves the same switch / router （ OQ ） behavior is equivalent.
