Global Synchronization Protection for Packet Queues
13 February 2014
Transmission capacity sharing TCP flows tend to synchronize among each other. This way rate variations of the individual flows, which are caused by the congestion control algorithms, do not even out. 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 packet queuing schemes that prevents global synchronization. The de-correlation between the individual flow variations reduces buffer demand and sojourn time of the queues.
