T比特IPv4/v6高性能路由器设计与实现

Design and Implementation of High Performance Terabits Router

互联网的高速发展,使得目前处于网络核心的路由器成为制约互联网可持续性发展的关键因素。随着网络新技术的引入和应用业务的增多,高性能路由器必须支持大容量、高吞吐率、低转发时延、IPv4/v6双协议栈和众多的路由协议。本文针对这些要求,详细阐述了T比特IPv4/v6高性能路由器的需求、系统设计、关键技术,为设计与实现高性能双协议栈路由器提供了一种可行的方案。

High speed growth of internet makes core routers in the present backbone network be the key factor of preventing internet from continuous development. With new network technologies introduced and applied traffics increased, high-performance routers must support large-capacity, high-throughput, low-forwarding-delay, IPv4/v6 protocol stack, and many routing protocol. In accordance with these demands, this paper describes demand-analysis, system-design, solution to key-technology for the high performance IPv4/v6 terabits router, and gives the available characteristics according to this design, which is a practical scheme for the implementation of high performance double-stack routers.
