多目的输出端口交换技术研究分析

On the Multi-Port Switching Technology

交换结构作为高性能路由器的核心,如何提高其交换容量的可扩展性和服务质量的可预测性,是近十年来网络研究的热点和难点问题。文章从路由交换协同设计的角度出发,提出了基于多下一跳路由的多目的输出端口交换技术,并对其可行性进行了分析。结果表明:新技术能够在很大程度上解决拥塞,提高交换单元性能,并且具有一定的抗毁性。

Switch fabric is a core element of the high performance router. How to enhance its switching capacity and the predictability of quality of service is the hot spot in network over the past decade. From the viewpoint of the cooperation with routing and switehing, this thesis proposes the multi-port switch based on multi-hop routing, and analyzes its feasibility. The result shows that this new technology can solve the congestion, enhance the performance of the switch fabrie, and keep survive in case of failure.
