Hybrid mapping service for the separation solutions of routing scalability
首发时间:2012-02-07
Abstract:In recent years, the global routing table size grows rapidly. The scalability of routing and addressing of Internet is concerned by network operators and research community. Among these proposed solutions, core-edge separation mechanism, represented by LISP are more acceptable than others. Mapping between globally routable IP addresses and destination IP addresses of edge network is the key component of these solutions. Although many mapping system have been proposed, their construction and maintenance is complicated, and have little incentive for deployment. In this paper, we present a practical approach to provide mapping service. This approach is a hybrid structure. Mapping servers are distributed and autonomous in regional network, and are connected together via extending DNS infrastructure and constructing an overlay network. It is easier to be deployed increasingly.

一种路由可扩展性分离方案的异构映射方法
摘要:近年来,全球路由表快速增长,互联网路由结构的可扩展性受到网络运营者和研究团体的关注。在提出的解决方案中,以LISP为代表的核心-边缘分离方案受较广泛认可。在核心网络地址和边缘网络地址之间的映射是该类方案的关键组成部分。虽然许多映射系统结构被提出,但是它们的构建和维护都非常复杂,部署的积累很小。在该文中,我们提出一种实用的提供映射服务的方法。这个方法采用了异构结构。映射服务器分散在区域网络,并由区域网络自治,然后通过已有的DNS域名解析基础设施和通过构建覆盖网络的方法连接起来。该方法比较容易渐增部署。
