ns2 is a network simulation tool, here three network congestion control algorithms on TCP connection for two traffic flows compared using ns2 and plotting average characteristics.

A TCP Congestion Control Simulator in Python that models the behavior of Slow Start, Congestion Avoidance, Timeout, and Fast Retransmit. The program randomly introduces packet loss and congestion events to visualize how the Congestion Window (cwnd) changes dynamically over time.
