摘要： 主干网络上的信息流量急剧增长,ISP不可能经常更新核心路由器以满足其需要,为保护现有投资,对核心路由器交换结构的可扩展性提出更高的要求·由于传统路由器的交叉开关体系结构的可扩展性差,在更高速度的太比特(Terabit,即1012bit)级路由器中必须采用新的体系结构,即可扩展的分布式交换体系结构·全面综述了近年来国内外在太比特级路由器方面研究的最新成果,介绍了太比特级路由器的新功能,以三维环形结构、三维圆环面(torus)结构、多维超立方体(hypercube)结构为例,对新一代太比特级路由器的分布式体系结构进行了分析和研究·展望了太比特级路由器技术的发展趋势·

Abstract: With the dramatic increment and development of traffic on the backbone, it's impossible for the ISPs to upgrade their core routers frequently, and the scalability of the core routers becomes the key issue for protecting investment. As the scalability of traditional routers based on crossbar switch architecture is poor, the scalable distributed switch architecture must be adapted in terabit routers. Summary of the latest research achievements and the new features of terabit routers are discussed. Based on the study of three-dimensional ring architecture, three-dimensional torus architecture and multi-dimensional hypercube architecture, a thorough analysis of the distributed architecture utilized in modem terabit routers is presented. The prospect of terabit router was investigated.
