Van Jacobson Congestion Control (1988)
Limit effective transmit window to lesser of advertised receive window or local congestion window (cwind)
Cwind starts @ 1 packet, expands 1 packet for every packet acked
- called “slow start” - a misnomer since it’s exponential over time!
If a timeout occurs, assume congestion:
- ssthresh = 1/2 cwind
- cwind = 1 packet
