Performance Evaluation of High Speed TCP Variants in Dumbbell Network

Abstract

Dumbbell topology evolved as a key topology for a large variety of applications ranging from home networking to transportation systems, campus network and medical systems. TCP is one of the core protocols of the internet protocol suite, reliability is the main constraint for the traffic flows in TCP. Even though congestion control mechanisms are implemented, packet losses are encountered which leads to performance degradation. In this paper, the congestion control algorithms are implemented and corresponding results are analyzed in Dumbbell topology, it is typically used to analyze the TCP traffic flows. Fairness of throughput is evaluated for different TCP variants using network simulator.
