Abstract：Bandwidth-delay product in MPLS is so high that TCP protocols hardly solve the congestion in MPLS. This paper proposes an Active Traffic and Congestion Control (ATCC) mechanism in MPLS and its model, which utilities the characters of MPLS. MPLS ATCC moves the endpoint congestion control algorithms into the network. The comparison with traditional TCP shows that ATCC can find and control the congestion in time, reduce the round-trip delay, and edit the ingress traffic. So MPLS ATCC improves the total throughput and the utility of buffer.
