Abstract

The invention discloses an adaptive MPTCP data scheduling method. The method includes that establishing a Markov model according to the congestion window of each subflow; calculating according to the Markov model to obtain the average congestion window size of each subflow; calculating according to the time stamp field to obtain the current round trip time value of each subflow; predicting according to the average congestion window size of each subflow and the round trip time value to obtain the average effective throughput on each subflow; dynamically adjusting the congestion window size of the minimum sub-flow according to the average effective throughput of each subflow to avoid the minimum sub-flow from congestion; and adjusting the slow start threshold according to the adjusted congestion window size to make the adjusted subflows at the congestion avoidance phase. The adaptive MPTCP data scheduling method overcomes the defects of the existing MPTCP data scheduling and congestion control technology, so that MPTCP can adaptively carry out more reasonable scheduling for network fluctuation and network isomerization, and the efficiency and reliability of multi-path data transmission can be improved.

Description

technical field

[0001] The invention relates to the technical field of data scheduling and congestion control, in particular to an adaptive MPTCP data scheduling method. Background technique

[0002] In recent years, with the increasing application of smart terminals and the continuous development of Internet communications, the demand for network applications for business volume is also increasing; network applications represented by big data applications, mobile TV, video calls, etc. Highly reliable fast data transmission technology is urgently needed as a support. The existing Internet uses the TCP / IP protocol family, among which the TCP protocol is the representative of the transport layer and has been most widely studied and used. However, the traditional TCP protocol cannot use multiple communication interfaces (such as Ethernet interface and WIFI interface) of intelligent terminals at the same time. When connecting end-to-end, only one interface can be used to establ...
