Improvement Ivestigation of the TCP Algorithms with Avoiding Network Congestion Based on OPNET

Abstract

The aim of this paper is to determine the performance enhancement of the network for eliminating congestion through the use of the benefits of algorithms. These algorithms can be used in hindering the congestion which may occur within the network that relies on a Transmission Control Protocol (TCP) protocol. This paper specifically focuses on demonstrating the function of TCP, and most especially the four (slow start, congestion avoidance, fast retransmit and fast recovery algorithms) that are applied in the control of congestion. In the study, the varying effects of connection link from PPP DS1 to PPP DS3 on the network's performance are investigated.
