Description
Summary:One of the major problems in Internet today is Network Congestion. TCP is used as a Transport Protocol for most of the applications on the Internet and is also responsible for adjusting to network congestion dynamically. The Active Queue Management algorithms (AQM) are used to reduce congestion, and in this paper two such AQM algorithms are considered. Here we look at the existing Explicit Congestion Notification (ECN) algorithm and a Queue Management Backward Congestion Control Algorithm (QMBCCA). A comparison is made between the two algorithms in terms of Fairness and Percentage Loss for short lived web transfers. We have found that there is a significant reduction in packet loss and improvement in fairness index when using QMBCCA when there were more number of TCP flows.
