摘要

IP服务质量是目前国际上的一个研究热点

IETF为此而定义了区分服务体系结构.然而

该体系中存在不公平问题.本文提出了一种直接拥塞反馈机制(DCCS)

配合网络边缘的动态流量调节(DTC)算法

能够为该体系提供很好的公平性.该机制不仅能保证响应流与非响应流之间的公平性

而且能解决响应流(如TCP)自身由于分组长度

微流数目及环回时延(RTT)等因素而产生的差异.

Abstract

IP QoS is a research focus.Recently IETF propose the Differentiated Services(DS) architecture to implement QoS in Internet.However

there exists unfairness in DS network.This paper proposes to use a Direct Congestion Control Scheme(DCCS) and Dynamic Traffic Conditioning(DTC) to achieve the fairness.It maintains the fairness between responsive and unresponsive aggregates as well as better allocations for responsive flows(TCP) with different packet length

micro-flow number

Round Trip Time

etc.
