Things I really like: * they used flent * Using "variance" as the principal signal. This is essentially one of the great unpublished and unanalyzed improvements on the minstrel algorithm as well * Conventional ecn response * outperforms bbr on variable links Only negative so far is I haven't found any published source to it. :( Otherwise a very promising start to a year. "The choice of feedback mechanism between delay and packet loss has long been a point of contention in TCP congestion control. This has partly been resolved, as it has become increasingly evident that delay based methods are needed to facilitate modern interactive web applications. However, what has not been resolved is what control should be used, with the two candidates being the congestion window and the pacing rate. BBR is a new delay based congestion control algorithm that uses a pacing rate as its primary control and the congestion window as a secondary control. We propose that a congestion window first algorithm might give more desirable performance characteristics in situations where latency must be minimized even at the expense of some loss in throughput. To evaluate this hypothesis we introduce a new congestion control algorithm called TCP D*, which is a congestion window first algorithm that adopts BBR's approach of maximizing delivery rate while minimizing latency. In this paper, we discuss the key features of this algorithm, discuss the differences and similarity to BBR, and present some preliminary results based on a real implementation." -- "For a successful technology, reality must take precedence over public relations, for Mother Nature cannot be fooled" - Richard Feynman d...@taht.net <Dave Täht> CTO, TekLibre, LLC Tel: 1-831-435-0729 _______________________________________________ Flent-users mailing list -- flent-users@flent.org To unsubscribe send an email to flent-users-le...@flent.org
