CUBIC TCP

From Wikipedia, the free encyclopedia

CUBIC is an implementation of TCP with an optimized congestion control algorithm for high speed networks with high latency (LFN: Long Fat Networks).

It is a less aggressive and more systematic derivative of BIC TCP, in which the window is a cubic function of time since the last congestion event, with the inflection point set to the window prior to the event.

CUBIC TCP is implemented and used by default in Linux kernels 2.6.19 and above.
