Event Title

Performance comparison of the TCP methods to control congestion

Session

Computer Science and Communication Engineering

Description

In this paper we will analyze and compare performances of the TCP NewReno, TCP Westwood and TCP Vegas methods to control congestion in the networks. Performance analysis in terms of: throughput, goodput, number of lost packets, and the cwnd dynamics are carried out by means of simulation using NS3 simulator. We have considered two scenarios. In the first scenario we have measured performances of each of the three methods operating individually, whereas in the second scenario performances are measured when they share the bottleneck link.

Simulation results show that in both scenarios TCP NewReno outperforms two other methods, followed by TCP Vegas. Whereas, in the second scenario, sharing the link resource, TCP Westwood shows better performances than TCP Vegas.
