摘要
随着互联网的应用发展,用户对带宽的需求日益增大。同时,伴随着宽带接入技术的发展,终端可以同时具有多条网络链接,然而传统传输控制协议(TCP)采取单路通信,因而造成资源浪费。为此,IETF专门提出了多路径TCP(MPTCP)来实现TCP的多路传输,从而提高链路利用率和协议鲁棒性。本文对国内外MPTCP的最新研究成果进行了总结,包括MPTCP的体系结构、路由和拥塞控制等内容,可为国内研究者进一步深入研究提供参考。
With the development of Internet applications,users＇ demand for bandwidth is soaring sharply.Meanwhile,along with the development of broadband access technology,the endpoint can also adopt multiple network accesses.But due to one-way communication of traditional Transmission Control Protocol（TCP）,the waste of resources will exist.To this end,IETF has specifically proposed Multi-Path TCP（MPTCP） to implement TCP multiplexing,thereby enhancing the efficiency and robustness.This paper gives a review of the IETF＇s research on MPTCP,including MPTCP architecture,routing and congestion control,aiming to provide a reference for deeply studying.
