区分服务在Linux上的实现

Differentiated Service Implemented on Linux

本文给出了 L inux流量控制的基本元素的简单介绍 ,并解释了如何把现有的体系结构加以扩展以支持 Diff-Serv。接着 ,说明了如何使用 L inux当前内核里的流量控制的结构来实现 L inux支持 Diff Serv机制。具体地给出了新的组件 :分类器、标记器和基于随机早期检测的 jjj PHB。

This paper gives a brief introduction to the basic elements in traffic control on Linux and a description of extending the existing architecture in order to support DiffServ. It then illustrates how to implement DissServ on Linux with the structure of traffic control in its current inner kernel. New components such as classifiers,markers and early-random-detection-based PHBs as well as the whole architecture of this model are also given in it.
