AI Technical Summary

Technical Problem

In existing technologies, when the encoding side performs congestion control based on data packet loss and latency, it may lead to an overall reduction in network transmission rate, making it unable to keep up with dynamic changes in the network in a timely manner, resulting in a decrease in network efficiency.

Method used

The first communication device acquires data stream traffic and network capacity information, predicts whether the network capacity can guarantee traffic demand, and performs adaptive control, such as adjusting the data stream buffer time, path selection, and transmission delay, to avoid network congestion.

Benefits of technology

Without modifying the congestion control algorithm or adding interfaces, it proactively addresses network congestion, improves user experience, reduces data packet loss, and ensures network transmission performance.

Abstract

Provided in the present application are a communication method and a communication apparatus. The method comprises: acquiring traffic information predicted for data of a first data flow, and network capacity information predicted for the data of the first data flow; and when it is determined, on the basis of the predicted traffic information and network capacity information, that a predicted network capacity cannot ensure predicted traffic requirements, performing first control on the first data flow. By means of future information that is predicted for data of a first data flow, whether the transmission policy of the first data flow needs to be actively adjusted in advance is determined, such that the probability of packet loss or high latency of the first data flow when a network capacity cannot guarantee the transmission of the first data flow during a certain future period of time can be reduced.
