An enhanced traffic marker for DiffServ networks

Abstract

In this paper, we propose an enhanced traffic marker (ETM) to amend the inappropriate marking in DiffServ networks. The ETM is based on the Two-Rate-Three-Color-Marker (TRTCM) scheme and introduces the feature of aggressive promotion and fair share marking. Simulation results show that the ETM fairly allocates bandwidth among micro-flows and achieves a higher throughput than TRTCM does.
