Performance Analysis of TCP Variants [ ]


TCP is considered as a reliable source for end-to-end delivery of packets under congestion. In this paper, we have used NS-2 to simulate different TCP variants on a simple network topology and analyzes their performance based on throughput, packet drop rate, and latency. We compare Tahoe, Reno, NewReno and Vegas to analyze their performance under congestion and fairness between them. We have also studied the influence of queuing disciplines DropTail and Random Early Drop (REM) on TCP SACK and Reno.
