Internet Congestion Control Protocol in a Complex Network

Abstract

Congestion control on the internet is a major function of the transmission control protocol (TCP). One major algorithm that works well with the TCP and supports its proper functioning is the Active Queue Management (AQM) Algorithm of which the Random Early Detection (RED) Architecture is a subset of. The RED architecture focuses on stabilizing the queue length, ensuring fairness in link flows and notifies the sources when congestion begins. This paper proposes a novel RED architecture called ‘Timed Out RED’ simulated and modelled with SimEvents which manages the queue length using timeouts to limit packet queuing time as the measure of controlling congestion in a complex network.
