分布式BGP协议体系结构

随着Internet规模的扩展和连接密度的增加,作为域间路由标准的BGP协议面临严峻挑战。集群路由器的出现,其分布式的计算资源、存储资源以及体系结构上的高度可扩展,有利于解决BGP协议面临的这些问题。在分析BGP协议体系结构无法适应集群路由器分布式特点的基础上,通过对BGP协议功能的解耦合,提出一种新的、分布式的BGP协议体系结构。与传统方式相比,分布式BGP体系结构能够充分利用集群路由器的分布式的计算资源和存储资源,在协议可靠性、管理维护成本、协议多维可扩展性和简化BGP网络设计等方面具有极大优势。

Distributed BGP Architecture

With the Internet continuing its expansion in range and its increase of linking density,the BGP routing protocol,which works as the inter-domain route standard,has met serious challenge.The emergence of clustered router,which has the advantages of distributed storage,computation resources and high extensibility in system and structure,is helpful for people to meet the challenges.Considering that BGP protocol architecture is not suitable for clustered router,this paper proposes a new distributed BGP architecture,which can take advantage of distributed resources of clustered router greatly.Compared with traditional BGP architecture,the distributed BGP architecture can improve protocol reliability,lower administration costs,simplify BGP network topology and improve BGP scalability.
