Abstract

The invention belongs to the technical field of network data transmission, and discloses an MPTCP network multipath combination selection system and method, and the method comprises the steps: classifying transmitted data streams according to the sizes of data needing to be transmitted by a current data stream; putting all the sub-flow paths in the network into an initial path set, updating the round-trip time delay of the paths in real time every time when the sending end receives one ACK data packet, and sorting the paths from small to large according to the current round-trip time delay ofthe paths and the sub-flow influence factors; and performing path selection according to the category to which the data stream belongs. According to the invention, the size of the transmission data and the influence factors of the sub-streams are combined, and part of the sub-streams are selectively used for network transmission; network resources are fully utilized, and better network service isprovided. According to the invention, the performance of the MPTCP in heterogeneous network transmission is improved; the network performance when the MPTCP in the heterogeneous network transmits relatively small data is improved; computing resources of a computer are saved; and network resources are utilized more effectively.

Description

technical field [0001] The invention belongs to the technical field of network data transmission, and in particular relates to an MPTCP network multipath combination selection method and system. Background technique [0002] Currently, the closest existing technology: MPTCP (MultiPathTCP (MultiPathTCP) was developed by the Internet Engineering Task Force (IETF) MultiPath TCP working group, which aims to allow Transmission Control Protocol (TCP) connections to use multiple paths to maximize The use of channel resources) is an extension of the traditional TCP protocol. Traditional TCP only supports single-path transmission. The introduction of multi-path transmission mechanism enables simultaneous utilization and sharing of multi-homed resources without changing the basic structure of TCP. The idea of ​​MPTCP is to share resources and distribute data streams to multiple parallel paths for simultaneous transmission to improve network bandwidth. [0003] At present, the perform...
