I was just reading some for QoS, Vegas, limiters.. etc.. And I understand Reno but then, I saw this in Wikipedia, FAST TCP, is a newer method and more efficient? Can it be implemented in Tomato? Interesting anywhere.
This is the link:
EDIT: It is commercial, but, is interesting, just look at Gargoyle-Router QoS, the ACC, which inspect RTT all the time to determine if a reduction of data width is required to prevent higher RTT and packet loses.
