Using Weighted Random Early Detection
.. RED works on the basis of active queue management, and addresses the
shortcomings of tail drop.
.. WRED was primarily designed for use in IP networks dominated by
TCP, because UDP traffic is not responsive to packet drop like TCP.
.. WRED treats non-IP traffic as precedence 0, the lowest precedence.
Therefore, non-IP traffic will be lumped into a single bucket and is
more likely to be dropped than IP traffic.This may cause problems if
most of your important traffic is something other than IP.
