Title : Global Synchronization Protection for Packet Queues

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.
