| 摘 要： | 自动请求重传(ARQ)的按序提交会产生重排序时延，增加分组的链路传输时间．提出了一种基于区分服务的ARQ架构，让不同服务质量(QoS)类别的流分别使用独占的分组队列和ARQ实体，使时延敏感分组不会因为等待普通数据分组的重传而经历不必要的重排序时延．仿真结果表明，该方案可以有效减少时延敏感分组的链路时延和传输时延．

| Abstract: | In-Order-Delivery of ARQ adds resequencing delay to packets' link transmission time. This paper presented an ARQ architecture based on differentiated service. It let traffic with differentiated QoS occupy the exclusive packet queue and ARQ entity, the delay-sensitive packets have packets queues and ARQ entities need not wait for the retransmission of ordinary data packets. So their link-delay can be significantly reduced, which is proved by the simulation results. |
