Performance Improvement of TFRC Congestion Control Algorithm in Wireless Network Streaming Media Transmission

This paper studies a rate-based TCP-Friendly Rate Control (TFRC) mechanism, which is widely used in multimedia real-time services, and analyzes its basic workflow, throughput model and calculation of key parameters. In order to meet the demand of real-time service for network transmission, the bandwidth-delay product (BDP) is applied to the congestion control of TFRC as the network congestion warning signal, and the improved TFRC algorithm is proposed. The simulation results show that this method can achieve good results in the network transmission of real-time services, and its friendliness and smoothness are improved to a certain extent.
