Research On Internet Congestion Control

Research on the Internet congestion control is becoming an important task in the present network development. The paper studied various algorithms of window-based TCP congestion control in depth, analyzed the algorithms in detail, and compared their validity and fairness based on simulation experiment. The paper also studied the throughput model of TCP and rate-based, TCP-friendly congestion control protocol TFRC was studied based on the model. Some advanced algorithms were devised to ameliorate some defects in TCP congestion control and rate-based congestion control and the algorithms were attested by simulation. Experiment model and network simulation platform were built in the work of the paper.
