I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. This document modifies the existing recommendation how small packets should be treated in the RED AQM algorithm. This document deprecates the deliberate preferential treatment of small packets in AQM algorithms. The new recommendation is that packet size is taken in to consideration when measuring congestion, but not to taken consideration when signaling that congestion by dropping packets. The security considerations section gives good explination how the new recommendation is better for security. I have no comments to the draft. -- kivinen at iki.fi
