Multi-stream transmission control method based on QUIC protocol

Abstract

The invention provides a multi-stream transmission control method based on a QUIC protocol, and the method comprises the steps: enabling a client to build a control channel, transmitting the bandwidth, time delay and packet loss rate information of a network card of equipment to a server, and building a multi-sub-stream transmission service; segmenting client user program data, distributing a unique identifier to each segmented data segment, issuing the unique identifiers to each sub-stream for transmission, recombining data according to the unique identifiers after a server receives the datasegments through a plurality of sub-streams, and delivering the recombined data to an upper-layer application to complete a multi-stream transmission task; aggregating bandwidths of a plurality of network cards according to different characteristics of user services so as to provide larger throughput bandwidths for users; selecting the substreams with smaller transmission time delay for data transmission, and redundantly transmitting the same service through the plurality of substreams at the same time, so the transmission quality is improved; moreover, the connection substreams can be dynamically added and deleted according to the network access condition of each piece of equipment and the user requirements, so that the network transmission quality of the user in a high-frequency mobile environment is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, and mainly relates to a multi-stream transmission control method based on the QUIC protocol. Background technique [0002] In the past few years, with the rapid development of mobile communication networks and smart terminals, the traffic of mobile terminals has shown exponential growth. The arrival of the 5G era has further increased the bandwidth of the network and greatly reduced the delay of the network. Many current devices basically support multiple network access methods, such as mobile phones supporting mobile cellular network access (3G, 4G, 5G), WIFI access, etc. But there is still a defect that only one network access method can be used at the same time. [0003] With the emergence of emerging applications such as Internet of Vehicles, VR, online teaching, telemedicine, and online conferencing, the problem of delay and bandwidth has become more and more prominent.
