基于开放接口的异构路由器集群

随着Internet速度和规模的持续增长以及各种新型服务和协议的不断涌现，现有的核心路由器已经越来越难以适应运营商的要求。文章指出集群结构是高性能路由器发展的趋势，在总结现有集群路由器相关研究的基础上，指出了目前同构路由器集群结构的不足。分析了路由器向标准化、模块化发展的趋势，以此为基础提出了一种新的路由器体系结构——基于开放接口的异构路由器集群CHR（Cluster of Heterogeneous Routers），并阐述了其可行性。给出了这种集群路由器体系结构的模型，并提出了今后需要重点研究的关键问题及研究思路。

Cluster of Heterogeneous Routers Based on Open Interfaces

With the fast growth of Internet traffic, and the continuous introduction of new services and protocols, existing core routers cannot adapt well to the requirements of carriers. In this paper, firstly, we analyze new carrier demands on next generation core routers, and indicate that applying a cluster based architecture is the direction for future high performance router design. Then based on the discussion about current related work on cluster based routers, we sum up the shortcomings of homogeneous cluster architecture. After we analyze the standardization and modularization trend for the development of router design, we propose a novel router architecture named CHR based on open interfaces. Its feasibility is also evaluated. Then we bring forward the model of this kind of architecture. The critical technologies and techniques of CHR routers based on open interfaces are presented.
