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.
