Delay-gradient congestion control

{{Redirect|TIMELY||punctuality}}

In computer networking, delay-gradient congestion control refers to a class of congestion control algorithms, which react to the differences in round-trip delay time (RTT), as opposed to classical congestion control methods, which react to packet loss{{cite web |url=https://lwn.net/Articles/645115/ |author=Jonathan Corbet |date=20 May 2015 |title=Delay-gradient congestion control |work=LWN.net }} or an RTT threshold being exceeded.{{cite conference |url=http://caia.swin.edu.au/cv/dahayes/content/networking2011-cdg-preprint.pdf |author=David A.
