In linux kernel since version 3.10 (release Date: 2013-06-30)
CAIA Delay-Gradient (CDG) is a TCP congestion control that modifies
the TCP sender in order to:
o Use the delay gradient as a congestion signal.
o Back off with an average probability that is independent of the RTT.
o Coexist with flows that use loss-based congestion control.
o Tolerate packet loss unrelated to congestion.

delay gradients." In Networking 2011. Preprint: http://goo.gl/No3vdg
