TCP Congestion Control slide update
Written on 26.07.2024 12:58 by Tiago Heinrich
Dear Students,
We updated the picture in the TCP Congestion Control Lecture slides (slides 45)
Explanations:
TCP Tahoe (unchanged)
- when a timeout occurs or three duplicated acks are detected the cwnd is set to 1 MSS and the slow-start phase restarts
TCP Reno (slightly changed)
- when a timeout occurs the cwnd is set to 1 MSS and the slow-start phase restarts
- when three duplicated acks are detected the ssthresh = cwnd/2
moreover the cwnd is set to ssthresh + 3 MSS (to account for the duplicated acks) (change)
Best regards,
Your DN team
