Abstract

Conventional works for the AF (assured forwarding) service in the differentiated services (DiffServ) have no sufficient consideration on the fairness of bandwidth share based the target rate and the impact of RTT and UDP. In order to solve these problems, we proposed a new packet marking scheme with fairness guarantee. The proposed scheme based on average transmission rate, using the achieved rate and fairness of each flow to provide fairly marking for assured forwarding services in DiffServ network. By adding a record unit and a promotion/demotion probability generator to the conventional traffic conditioner, the impacts of RTT, UDP/TCP interactions, and different target rates can be mitigated effectively. The performance of the proposed scheme, compared with TSW3CM, is evaluated with the ns-2 simulator.
