An active traffic and congestion control mechanism in MPLS

摘要

摘要: MPLS是具有大带宽一时延迟的网络，用传统的TCP解决MPLS拥塞问题显得十分困难，该文结合MPLS的网络特点，提出了一种适合MPLS网络的主动式流量和拥塞控制机制，在网络边缘节点引入拥塞反馈处理，对实验模型进行了性能仿真分析，实验证明，与传统的TCP协议相比，该机制将流量和拥塞控制从用户端点扩展到MPLS边缘路由器，能够更及时地检测和控制网络拥塞，缩短了控制时延，可以进行较精确的流量调节，实现了提高吞吐量和改善缓冲区利用率的目的。

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.
