Hi, I have reviewed draft-ietf-aqm-fq-implementation-02 as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. I believe the document is 'Ready' for publication. The informational document is to some extend a tutorial on queuing, marking and dropping algorithms. The main observation stated in the conclusions of the document is that marking/dropping algorithms are conceptually separate from queueing mechanisms and that specifications should decouple them even though they might be implemented in a coupled manner. I think it would help the reader if the abstract would be expanded. OLD This note discusses implementation strategies for coupled queuing and mark/drop algorithms. NEW This note discusses queuing and marking/dropping algorithms. While these algorithms are often implemented in a coupled manner, this note argues that specifications, measurements, and comparisons should decouple the different algorithms and their contributions to system behavior. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 < http://www.jacobs-university.de/ >
