【Abstract】 The improvement to conventional TCP/IP congestion mechanism in MPLS is proposed, in which endpoint congestion control algorithms are moved into network. The simulation shows that with the new mechanism, congestion can be inspected and controlled in time, round-trip delay is reduced and ingress traffic is edited. Thus total throughput and utility of buffer are improved.更多还原
