Data flow control method and device

Abstract

A method of data flow control is described. When an initial transmission path is selected for a newly created data stream, the output completion time (FCT) of the data stream using the plurality of networks is estimated, and the network with the shorter estimated time is selected to transmit the data stream. On the other hand, in the data stream transmission process, the network transmission requirement of the application corresponding to the sent data message is identified, the transmission performance on the current path is evaluated based on the service type borne by the data stream, and whether the data stream needs to be changed or not is determined based on the transmission performance of the link accessed by the current terminal, for example, the data stream is terminated. In this way, the transmission performance of the data stream can be better guaranteed, and the advantages of the multi-path transmission technology are exerted.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data flow control method and device. Background technique [0002] Computer applications often involve the interaction of information. The multi-path transmission technology transmits data in parallel through multiple subflows (subflows) between the client and the server, and each subflow corresponds to a path (path). For example, the Multiple Path Transmission Control Protocol (MPTCP, Multiple Path Transmission Control Protocol) is based on the Transmission Control Protocol (TCP, Transmission Control Protocol). Multi-path transmission technologies may be collectively referred to as MP technologies, where a connection includes multiple sub-flows, then the connection is called a multi-path connection, that is, an MP connection. Wherein, each sub-flow in the multiple sub-flows corresponds to a link between the client and the server, and the links corresponding to the multiple ...

Problems solved by technology

[0004] Since the multi-path technology increases the available data transmission paths, in actual application scenarios, how to reasonably allocate the data to be transmitted by a device on these paths, so as to better utilize the multi-path technology should be better than Under the same network environment, the transmission performance (such as throughput or delay) of a single-path connection is a hot research issue at present. Under the existing solutions, the advantages of multi-path technology cannot be fully utilized, and sometimes even Not as good as single path connection transfer performance
