The differentiate services (DiffServ) is proposed to provide packet level service differentiations in a scalable manner. To provide end-to-end service differentiation to users having a connection over multiple domains, an intermediate marker is necessary at the edge routers. The intermediate marker has a fairness problem among the TCP flows due to the TCP's congestion control. In this paper, we propose an aggregate fairness marker (AFM) as an intermediate marker which works with a user flow three color marker (uf-TCM) operating as a flow marker for a user flow. Through the simulations, we show that the proposed AFM can improve fairness to the TCP flows with different RTTs.
