Sorry; yes Sawtooth is the more accurate term. I see this on a daily occurance with large data-set transfers; generally if the data-set is large multiples of the initial window. I've never tested medium latency( <100ms) with small enough payloads where it may pay-off threading out many thousands of sessions. However, medium latency with large files (50M-10G) threads well in the sub 200 range and does a pretty good job at filling several Gig links. None of this is scientific; just my observations from the wild.....infulenced by end to end tunings per environment. On Tue, Jun 18, 2013 at 7:45 AM, Jakob Heitz <jakob.heitz () ericsson com>wrote:
Thanks Fred. Sawtooth is more familiar. How much of that do you actually see in practice? Cheers, Jakob.
