摘　　要：利用终端的多宿主特性实现多路径传输是因特网协议的一个热点研究问题,MPTCP和CMT-SCTP是目前比较成熟而关键的两个多路径传输协议,但在大规模应用前还需要作大量的性能测试分析研究。在本地测试床环境中,对MPTCP和CMT-SCTP多路径传输实际吞吐量的性能进行对比测试与分析。结果表明MPTCP和CMT-SCTP都能获得吞吐量的提高,但传输调度算法仍然不完善,需要进一步改进。Achieving multipath transport by terminal＇ s multi-homed characteristics is a hot topic of Internet protocol application. MPTCP and CMT-SCTP are both more mature and key protocols for multipath transmission, but there is still a lot of performance analysis needed before large-scale application. This paper presents the behaviors of MPTCP and CMT-SCTP multipath transmis- sion and compares the difference between both protocols on the local test-bed environment. Results show that both MPTCP and CMT-SCTP protocols can significantly increase throughput. Meanwhile the scheduling strategy for transmission is still not perfect and needs further improvement.
