In this paper, we consider two fairness problems that occur in the infrastructure network (fairness between TCP uplink/downlink flows and fairness between competing TCP uplink flows). A large number of existing works have studied the TCP fairness issues and greatly solved the TCP unfairness problems. However, these solutions suffer from the drawback of TCP(More)
The saw-tooth like behaviors of TCP impact Assured Forwarding Service flows in a differentiated services (diffserv) network. Therefore, we argue the use of TCP-friendly building blocks (or modules) and fairness modules in the diff-serv architecture regarding this issue, and propose Two Markers System (TMS) that is able to properly mark packets and fairly(More)
There are two cruxes of issues identified in differentiated services (diffserv) networks: One is TCP dynamics over Assured Services, and the other is the interaction of TCP and UDP flows for Assured Forwarding Per Hop Behavior (PHB). Therefore, we argue unfair distribution of excess bandwidth in an over-provisioned networks as well as unfair degradation in(More)
