FloadAutoRED: an AQM scheme to Increase the Overall Performance in Internet Routers

The Routers in Internet face the problem of congestion due to the increased use of Internet. Active Queue Management has provided a solution to the problem of congestion control in the Internet routers. But as data traffic is bursty in routers, burstiness must be handled without comprising the high link utilization and low queuing delay. Congested link leads to many problems such as large delay, unfairness among flows, underutilization of the link and packet drops in burst. In the last decade various AQM algorithms have been evolved to solve these problems of congestion in routers. RED based algorithms use queue length as congestion indicator while some of them use flow information for more accurate congestion indication. Some AQMs have been designed to use the input rate as the congestion indicator. In this paper, we propose an AQM scheme that considers the advantages of these queue length based, rate based and flow based algorithms and satisfies the QOS requirements of the network. This proposed scheme aims to increase the overall performance even under heavy load and shields the responsive flows form unresponsive flows to offer a good Quality of Service to all users.
