區分服務Diffserv 在QOS 網絡體系結構越來越受到廣泛的應用，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 的實現方案。重點介紹了數據包分類機
構和流量控制機構的實現。該實現方案在國家863 項目“可擴展到T 比特的高性能IPv4/v6路由器基礎平臺及實驗系統”上測試已通過，并取得了較好的結果。

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.
Key words: Diffserv，router, priority, scheduling
