| Abstract: | Congestion control is an important and difficult point in the computer network course. By introducing NS3 network simulation tool, this paper discusses the methods and steps of constructing complex hybrid network experimental environment and realizes several network experimental scenes based on 4:4 dumbbell network topology. Based on the size of congestion window, the theoretical verification experiments of several common congestion control algorithms are carried out. Based on the throughput, the fairness between the same congestion control algorithms and the friendliness between different congestion control algorithms are compared. The experimental results are consistent with the theoretical analysis, and the algorithm idea and control process of congestion control are visually displayed. |
