Tahoe & Reno

From Claude with some prompting
This image is a diagram explaining the TCP Congestion Control mechanisms, particularly comparing the congestion control algorithms of two TCP versions: Tahoe and Reno.

Key points:

1. Both algorithms use a Slow Start Threshold (ssthresh) to determine the initial congestion window size.
2. The congestion window grows exponentially (2^n) at first, then switches to linear growth (+1) once it reaches ssthresh.
3. Both algorithms reduce the congestion window to 1 and adjust ssthresh to half of the current size upon a timeout.
4. When receiving 3 duplicate ACKs (3 DUP ACK), both algorithms halve their ssthresh.

Difference:

• On 3 DUP ACK:
  • Tahoe: Reduces congestion window to 1
  • Reno: Multiplicatively decreases congestion window

There doesn’t appear to be any incorrect information in this image. It accurately shows the key difference between Tahoe and Reno in their response to 3 DUP ACK situations, and correctly explains other aspects of congestion control as well.
