In this research paper we compares 4 existing TCP congestion control mechanisms namely TCP-Reno, New Reno, Vegas and Sack 1 Four nodes, each generating a particular traffic are considered, and they are connected to a bottle-neck link which in turn is connected to the sink. After comparision of these 4 congestion control mechanisms we provide a TCL script that compare these algorithms performance. Congestion management techniques control congestion after it has occurred. One way that network elements handle an overflow of arriving traffic is to use a queuing algorithm to sort the traffic, then determine some servicing method of prioritizing it onto an output link.
