【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。更多还原

【Abstract】 Multi-path TCP( MPTCP) and Concurrent Multipath Transfer for SCTP( CMT-SCTP) are two technologies of the concurrent multi-path transfer for NGI,w hich are hot topics. Compared w ith the traditional TCP and SCTP,the congestion control of multi-path transport protocols w ill face the problem of unfairness. This paper begins w ith 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.更多还原
