FAuto RED With RED: An Algorithm to Increase the Fairness in Internet Routers

摘要

Routers in Internet face the problem of congestion due to the increased use of Internet. AQM algorithm is a solution to the problem of congestion control in the Internet routers. As data traffic is bursty in routers, burstiness must be handled without comprising the high link utilization and low queuing delay. Congested link causes many problems such as large delay, unfairness among flows, underutilization of the link and packet drops in burst. There are various existing algorithms that have been evolved over the past few years to solve these problems of congestion in routers. RED based algorithms only use queue length as congestion indicator to indicate congestion. In this paper, we propose an AQM scheme that considers only the advantages of these queue length based and uses the flow information and satisfies the QOS requirements of the network. This proposed scheme aims to provide good service under unresponsive load and shields the responsive flows from unresponsive flows to offer a good QOS to all users.
