路由器多框集群的设计与实现

随着互联网的普及化、商用化和宽带化，互联网建设应以满足不断增长的信息消费者业务需求为导向，来构建新一代互联网建设模型。该建网模型应能满足下一代互联网“大容量、可扩展、高可用、可管控”的综合多业务承载的需要。集群就是一种最有杈的解决扩展性问题的技术，它服务于核心层，可在方便维护、不增加网络复杂度的前提下，用更加廉价的手段来满足业务高速增长、网络性能及容量提升的需求，以降低网络的建设成本和维护成本。该文研究了集群技术，给出了路由器多框集群体系结构，探讨了未来高端路由器的发展趋势。

The Design and Realization of Multi-Chassis Router

With the popularization of Internet and broadband business, Internet should be constructed to meet the growing information needs of the consumer-oriented business. Building the next generation Intemet model, it should be able to satisfy the next-generation In- teruet which is ＂large-capacity, scalable, high availability and well i,aanageability＂ and will bear integrated multi-service. Cluster is one technology of the most effective solutions of the scalable problem. Running in the core layer, it can facilitate maintenance. Without increasing the network complexity of premise, it gives more low-cost means to meet the rapid growth of business, network performance and capacity. In this paper,by studying cluster technology, we give the architecture of Multi-Chassis router and the development trend of high-end routers.
