Abstract: Multi-path TCP(MPTCP) and Concurrent Multipath Transfer for SCTP(CMT-SCTP) are two technologies of the concurrent multi-path transfer for NGI,which are hot topics. Compared with the traditional TCP and SCTP,the congestion control of multi-path transport protocols will face the problem of unfairness. This paper begins with an overview of the traditional TCP congestion control algorithm,and then in view of the unfairness of concurrent multi-path transfer,basing on the resource pooling method,it introduces the slow start threshold ratio factor,increase factor,per-flow aggressiveness factor,deduces three new algorithms to solve the problem of unfairness,and carryies out the contrastive analysis through simulation.

Key words: multi-path transfer, congestion control, fairness, Resource Pooling(RP), increase factor, aggressiveness factor

摘要: 多路径传输控制协议(MPTCP)与并发多路径传输控制协议(CMT-SCTP)是下一代互联网多路径并发传输的2 种热点技术,但传统拥塞控制算法只适合于单路径传输,应用于多路径传输时会面临公平性的问题。为此,研究传统TCP 拥塞控制算法,针对多路径并发传输的不公平性问题,基于资源池思想,引入慢启动阈值比因子、增长因子和抢占因子,给出3 种新的拥塞控制算法,并通过仿真进行对比分析。
