Abstract

The present invention provides a data transmission method and device, which belong to the technical field of computer communication and are applied in SDN-based MPTCP. The method includes: obtaining a disjoint path set of the current network; and obtaining a subflow based on the disjoint path set and send the number of sub-flows to the data sending terminal for the data sending terminal to establish a target sub-flow; receive the path allocation data packet sent by the data sending terminal through the target sub-flow; and based on the The path allocation data packet allocates a path in the disjoint path set to the target subflow, so that the data sending terminal can perform data transmission according to the allocated path. The data transmission method and device provided by the present invention regularly collect network status from a global perspective, determine the appropriate number of sub-flows according to service requirements and network resource capabilities, make full use of network bandwidth, and slow down the disorder of data packets at the data receiving end situation, so as to achieve efficient data transmission.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a data transmission method and device. Background technique [0002] At present, more and more terminal devices are equipped with multiple network interfaces, and at the same time, the demand for high bandwidth of network services is increasing sharply. Therefore, how to improve the efficiency and quality of data transmission is a technical problem in this field. [0003] In the prior art, the multipath transmission control protocol (Multipath TCP, MPTCP), as an extension of TCP, is an end-to-end transport layer protocol. The protocol sets a plurality of fixed number of sub-flows (TCP connections) and connects different The sub-flows of the network are configured on the path, so as to achieve the purpose of aggregating the bandwidth of multiple paths to improve the transmission rate and transmission quality. [0004] However, MPTCP in the prior art is an end-to-en...
