Abstract
The saw-tooth like behaviors of TCP impact Assured Forwarding Service flows in a differentiated services network. Therefore, we argue the use of TCP-friendly building blocks(or modules) and fairness modules in the Differentiated Services architecture regarding this issue, and propose Two Markers System(TMS) that is able to properly mark packets and fairly share the bandwidth to each flow for their targeted sending rates. TMS has two marking modules that are placed on the source and the edge of a differentiated services network. For sources of the network, the virtual source making modules play important roles of reducing TCP impacts in the assured services and suitable marking packets. Next, in the edge of the network, the edge embedded marking module conducts new fairness policy based on the marking rate of flows from sources, so called “marking rate-based fairness”. Finally, we present simulation results to illustrate the effectiveness of TMS scheme over several parameters. That is, Two Markers System reduces TCP impacts over assured service and fairly shares the bottleneck link bandwidth of a network.
