Abstract

The invention discloses a multipath transport control protocol (MPTCP) based congestion control method and apparatus. The method comprises the steps of establishing an MPTCP connection, and allocating a buffer region for each TCP substream in the MPTCP connection; estimating the occupation ratio of the buffer region of each TCP substream; and determining the congestion level of the TCP substream according to the occupation ratio of the buffer region, and adjusting the transmission rate of the TCP substream based on the congestion level. According to the MPTCP based congestion control method and apparatus, the buffer region is split for each substream, then whether congestion exists is detected accurately according to the use ratio of the buffer region of each substream, the traffic is regulated and controlled level by level according to the congestion level, and MPTCP transmission fairness is also taken into consideration, so that the network throughput change more smoothly, and the link use ratio, throughput and robustness of the MPTCP are improved.

Description

technical field [0001] The invention relates to the technical field of network data transmission, in particular to an MPTCP-based congestion control method and device. Background technique [0002] Nowadays, with the rapid development of network technology, the traditional TCP protocol has gradually exposed the limitations that cannot adapt to the development. When the traffic in the network continues to increase, the traditional TCP protocol restricts all traffic to a single path, which fails to make effective use of network resources. Single-path TCP transmission can no longer fully satisfy modern high-speed transmission. MPTCP (MultiPathTransportControlProtocol, multipath transmission protocol) is an extension of traditional TCP, which efficiently transmits data through multiple paths between communication source and destination nodes, and provides end-to-end reliable, orderly and fast data transmission. Compared with the traditional TCP, the MPTCP protocol has two rema...
