parent[TCP]: Add TCP Vegas congestion control module. (diff)
[TCP]: Add H-TCP congestion control module.
H-TCP is a congestion control algorithm developed at the Hamilton Institute, by Douglas Leith and Robert Shorten. It is extending the standard Reno algorithm with mode switching is thus a relatively simple modification. H-TCP is defined in a layered manner as it is still a research platform. The basic form includes the modification of beta according to the ratio of maxRTT to min RTT and the alpha=2*factor*(1-beta) relation, where factor is dependant on the time since last congestion. The other layers improve convergence by adding appropriate factors to alpha. The following patch implements the H-TCP algorithm in it's basic form.
