The invention discloses a
QUIC flow concurrent number dynamic adjustment method and
system for 5G / 6
G network file transmission, and belongs to the technical field of
network communication. In order to solve the technical problems of concurrent adjustment lagging and unstable performance under 5G / 6G link
mutation, the method comprises the following steps: establishing a fast
user datagram protocol internet connection, and executing initial sampling based on a self-adaptive smooth round-trip
delay period; calculating a utility value reflecting the transmission comprehensive performance by using the collected
link data, and constructing a
Gaussian process regression mapping model; calculating the improvement potential of the candidate
concurrency number based on the mapping model, and selecting an optimal target
concurrency number; and integrating the optimal target
concurrency number and the current concurrency number upper limit dynamic adaptive
flow number, executing capacity limiting
processing when a link abnormal event is monitored, and updating the concurrency number upper limit so as to trigger a
closed loop iterative optimization process. According to the method, the convergence speed and
throughput efficiency of
batch file transmission of the 5G / 6G
cellular network can be remarkably improved.
