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.
