A Traffic Conditioning Algorithm for Enhancing the Fairness Between TCP and UDP Flows in DiffServ (original) (raw)

Abstract

The Differentiated Services Network (DiffServ) aims to offer differ-ing levels of quality of service to different customers and their traffic flows. One important part of the traffic conditioner in DiffServ is measuring the traffic against the traffic profile and then marking the packets accordingly. In this paper, we propose the enhanced marking algorithm, which can assure the reserved rates of TCP and UDP flows and support fair distribution of excess bandwidth. We experiment with the proposed algorithm using ns-2 simulator. The simulation results show that our proposed marking scheme is rather insensitive of the effect of UDP on TCP throughput, and performs better both in terms of throughput assurance and fair distribution of excess bandwidth in case of well-provisioned and over-provisioned network environment.
