EE 122: Congestion Control The Sequel

EE 122: Congestion Control The Sequel. October 1, 2003. Quick Review. Slow-Start: cwnd++ upon every new ACK Congestion avoidance: AIMD if cwnd > ssthresh ACK: cwnd = cwnd + 1/cwnd Drop: ssthresh =cwnd/2 and cwnd=1 Fast Recovery: duplicate ACKS: cwnd=cwnd/2 Timeout: cwnd=1. TCP Flavors.
