nAlgorithm:
–increment CongestionWindow by one packet per RTT (linear
increase)
–divide CongestionWindow by two
whenever a timeout occurs (multiplicative decrease)
nIn practice:
increment a little for each ACK
–Increment = (MSS * MSS)/CongestionWindow
–CongestionWindow += Increment
Additive
Increase/Multiplicative Decrease
