  Abstract

In this paper, we propose an Aggregate Fairness Maker (AFM) required for an Edge router to improve fairness of throughput among the flows of Assured Service in DiffServ with different round trip time (RTT) and we propose a user flow Three Color Marker (uf-TCM) as a flow marker that marks packets from the flow as green, yellow, or red. A yellow packet is the packet that consumes loss token in uf-TCM as well as that is demoted green packet in AFM due to disobey the aggregate traffic profile. The proposed AFM promotes yellow packet to green packet or demotes green packet to yellow packet through the fair method without per-flow management, and it improves the fairness of throughput among the flows as well as link utilization. A yellow packet and a red packet have the same drop precedence at Core Router in our scheme. So we can use the RIO buffer management scheme. We evaluated the performance of our proposed AFM and the RED? Marker that was proposed to improve fairness without per-flow management. Simulation results show that, compared with the RED? marker, proposed AFM can improve performance of throughput fairness among the flows with different RTT and link utilization under the over-provisioning, exact-provisioning, and under-provisioning network environments at Multiple DiffServ domains as well as at Single DiffServ domain.
