+       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
