Dear all, I posted an updated draft on Global Synchronization Protection (GSP).
Initially focused on global synchronization alone, it turns out that GSP essentially performs at the same level as the other AQMs. Major changes are wrt - a more detailed description of the parameter adaptation algorithm - an additional section on delay based operation Comments are highly welcome.

Name: draft-lauten-aqm-gsp Revision: 01 Title: Global Synchronization Protection for Packet Queues Document date: 2014-07-04 Group: Individual Submission Pages: 10 URL: http://www.ietf.org/internet-drafts/draft-lauten-aqm-gsp-01.txt Status: https://datatracker.ietf.org/doc/draft-lauten-aqm-gsp/ Htmlized: http://tools.ietf.org/html/draft-lauten-aqm-gsp-01 Diff: http://www.ietf.org/rfcdiff?url2=draft-lauten-aqm-gsp-01 Abstract: The congestion avoidance processes of several transmission capacity sharing TCP flows tend to be synchronized among each other, so that the rate variations of the individual flows do not compensate. In contrary, they accumulate into large variations of the whole aggregate. The effect is known as global synchronization. Large queuing buffer demand and large latency and jitter are the consequences. Global Synchronization Protection (GSP) is an extension of regular tail drop packet queuing schemes that prevents global synchronization. For large traffic aggregates the de-correlation between the individual flow variations reduces buffer demand and packet sojourn time by an order of magnitude and more. Even though quite simple, the solution has a theoretical background and is not heuristic. It has been tested with a Linux kernel implementation and shows equivalent performance as other relevant AQM schemes. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
