AQM Evaluation Guidelines


Unmanaged large buffers in today’s networks have given rise to a slew of performance issues.  These performance issues can be addressed by some form of Active Queue Management (AQM), optionally in combination with a packet scheduling scheme such as fair queuing. The IETF AQM working group was recently formed to standardize AQM schemes that are robust, easily implemented, and successfully deployed in today’s networks.  This document describes various criteria for performing precautionary evaluations of AQM proposals. This document also helps in ascertaining whether any given AQM proposal should be taken up for standardization by the AQM WG.
