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。 |

Abstract: |
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. |
