摘要

下一代路由器需要具有数百Gbps交换容量的高性能交换架构。在本文中，我们提出并分析了一种并行分组交换机，它具有160 Gbps的全双工交换背板，支持16个端口，每个端口以OC192c (10 Gbps)线速率工作。该交换机采用并行处理策略，支持变长流量。在此基础上，提出了一种简单新颖的QoS保证调度算法IPRR(入口优先轮询)。通过与iSLIP算法的比较，证明了IPRR算法能够更好地对网络流量进行QoS(服务质量)控制。

Analysis of a QoS-based parallel packet switch for core routers

High performance switch architectures with hundreds of Gbps switching capacity are needed in the next-generation routers. In this paper, we propose and analyze a parallel packet switch, which has a 160 Gbps full-duplex switched backplane, supporting 16 ports, each operating at OC192c (10 Gbps) line rate. This switch uses parallel-processing policy and can support variable-length traffic. Based on it, we also present a simple and novel QoS guaranteed scheduling algorithm, named IPRR (inlet priority round robin). By comparing it with the noted iSLIP algorithm, we prove that IPRR can provide better QoS (quality of service) control to network traffic.
