Performance Analysis of Transmission Control Protocol (TCP) Variants

TL;DR

This paper compares the performance of different TCP variants like Reno, Tahoe, Vegas, and SACK using NS2 simulations to measure throughput, delay, and drop rate under various network conditions.

Contribution

It provides a comprehensive performance analysis of multiple TCP variants under different traffic and bandwidth scenarios using NS2.

Findings

TCP variants show different throughput and delay characteristics.

SACK improves packet loss handling.

Performance varies significantly with network conditions.

Abstract

There are various TCP variants such as Reno, Tahoe, Vegas, SACK and so on. These variants implement algorithms that handle congestion control. In our experiments we have used these variants to measure their performance such as throughput, delay (latency), and drop rate with respect to time and Constant Bit Rate (CBR) - no congestion control, specified bandwidth and sends packets at a specified rate. We have used the NS2 network simulator to perform all our experiments to analyze TCP performance.
