Implementation of improved congestion control algorithm based on FPGA

In order to solve the problem of low bandwidth utilization and low application data sending and receiving rate of the network card in the Internet environment with high delay and high packet loss rate, this paper optimizes the network congestion control algorithm that causes this problem. By improving the congestion landmark and congestion detection algorithm, the bandwidth utilization and congestion startup and recovery speed are improved, thus improving the overall bandwidth utilization and application data sending and receiving rate.
