A TCP friendly fairness architecture for DS IP networks
区分服务网络中的TCP友好公平体系

Differentiated Services(DS) architecture has been proposed by IETF to implement QoS in IP networks. However, research shows that there exists unfairness in DS network. This paper introduces the TCP friendly concept into DS network and defines TCP friendly fairness in DS architecture. Elaborate simulations are used to verify that current mechanisms in DS cannot guarantee the TCP friendly fairness; therefore, direct congestion control scheme is proposed to achieve the TCP friendly fairness.
