區(qū)分服務(wù)Diffserv在高性能路由器中的實現(xiàn)

區(qū)分服務(wù)Diffserv 在QOS 網(wǎng)絡(luò)體系結(jié)構(gòu)越來越受到廣泛的應(yīng)用，它具有很強的擴展
性。本文給出了一種高性能路由器中支持Diffserv 的實現(xiàn)方案。重點介紹了數(shù)據(jù)包分類機
構(gòu)和流量控制機構(gòu)的實現(xiàn)。該實現(xiàn)方案在國家863 項目“可擴展到T 比特的高性能IPv4/v6路由器基礎(chǔ)平臺及實驗系統(tǒng)”上測試已通過，并取得了較好的結(jié)果。

Abstract –Differnetiated Service Diffserv is becoming very popular in designing QOS network:it has strong expansibility.This paper introduces an implementation of diffserv in hign performance router,presents the architecture of packet marking and traffic-control. The method passes through the country’s 863 project testing on
" Tbit router ", and the result is satisfying.
