Router-assisted congestion control

Router-assisted congestion control. Lecture 8 CS 653, Fall 2010. TCP congestion control performs poorly as bandwidth or delay increases. Shown analytically in [Low01] and via simulations. Avg. TCP Utilization. Avg. TCP Utilization. 50 flows in both directions Buffer = BW x Delay

Router Congestion Control: RED, ECN, and XCP

Router Congestion Control: RED, ECN, and XCP. Where we left off. Signal of congestion: Packet loss Fairness: Cooperating end-hosts using AIMD Next lecture: Enforcement for QoS, rate, delay, jitter guarantees But note: A packet drop is a very blunt indicator of congestion
