Abstract

Previous works for the AF (Assured Forwarding) service in a Differentiated Service (Diffserv) network have no sufficient consideration on the proportional fairness of bandwidth share based on RTTs, the target rates, and the impact of UDP against TCP. In order to solve these problems, we propose the Fair Differentiated Service Architecture (FDSA), Target rate and RTT Aware Three Color Marking (TRA3CM), and Target Rate Based Dropping (TRBD) mechanisms. These mechanisms provide three color marking and proportional fair bandwidth share among flows by considering RTT, target rate, and UDP flows simultaneously. In the results of comparing the performance among existing and proposed mechanisms, the proposed mechanisms are able to mitigate the RTT and UDP effect better than the existing ones. In addition, the proposed mechanisms are shown to provide the fair bandwidth share proportional to various target rates.
