Hi,Thanks for the review!I have attempted to incorporate all of your excellent feedback in draft revision 15, which I just posted. The diffs between revisions 14 and 15 are here:The draft itself summarizes the changes in revision 15, but I'm pasting them here as well, for easy reference:---<t>About revision 15:</t>
<ul>
<li>Fixed the description of the initialization of RecoverFS to match the latest RecoverFS pseudocode</li>
<li> Add a note that in the first example both algorithms (RFC6675 and PRR) complete the fast recovery episode with a cwnd matching the ssthresh of 20.</li>
<li>Revised order of 2nd and 4th co-author</li>
<li>Numerous editorial changes based on 2025-05-27 last call Genart review from Russ Housley, including the following changes.</li>
<li>Fixed abstract and intro sections that said that this document "updates" the experimental PRR algorithm to clarify that this document obsoletes the experimental PRR RFC</li>
<li>To address the feedback 'The 7th paragraph of Section 5 begins with "A final change"; yet the 8th paragraph talks about another adaptation to PRR', reworded the "A final change" phrase.</li>
<li>Moved the paragraph about measurement studies to a new "Measurement Studies" section, to address the feedback: 'The last paragraph of Section 5 is not really about changes since the publication of RFC 6937'</li>
<li>Fixed various minor editorial issues identified in the review</li>

Internet-Draft draft-ietf-tcpm-prr-rfc6937bis-15.txt is now available. It is a
work item of the TCP Maintenance and Minor Extensions (TCPM) WG of the IETF.
Title: Proportional Rate Reduction for TCP
Authors: Matt Mathis
Neal Cardwell
Yuchung Cheng
Nandita Dukkipati
Name: draft-ietf-tcpm-prr-rfc6937bis-15.txt
Pages: 26
Dates: 2025-05-27
Abstract:
This document specifies a standards-track version of the Proportional
Rate Reduction (PRR) algorithm that obsoletes the experimental
version described in RFC 6937. PRR provides logic to regulate the
amount of data sent by TCP or other transport protocols during fast
recovery. PRR accurately regulates the actual flight size through
recovery such that at the end of recovery it will be as close as
possible to the slow start threshold (ssthresh), as determined by the
congestion control algorithm.

Reviewer: Russ Housley
Review Date: 2025-05-27
IETF LC End Date: 2025-06-06
IESG Telechat date: Not scheduled for a telechat
Summary: Almost Ready
Major Concerns: None
Minor Concerns:
The Abstract and Section 1 say that this document "updates" the
experimental PRR algorithm. This wording is confusing because this
document obsoletes RFC 6937. The Abstract and Section 1 should
state that this document obsoletes RFC 6937. Avoiding the use of
"updates" is desirable.
The 7th paragraph of Section 5 begins with "A final change"; yet the
8th paragraph talks about another adaptation to PRR.
The last paragraph of Section 5 is not really about changes since the
publication of RFC 6937. I'm not sure where this information belongs.
Nits:
Section 5: s/(i.e. sndcnt is 0)/(i.e., sndcnt is 0)/
Section 5: s/RTO/retransmission timeout (RTO)/
Section 5: s/sets cwnd = ssthresh/sets cwnd to ssthresh/
Section 5: s/ECN/Explicit Congestion Notification (ECN)/
Section 5: s/AQMs/ approaches to Active Queue Management (AQM)/
Section 9: Figure 1 is too wide. Can segment 22 be omitted? If so,
the text that follows would say: "ACK#22 (not shown) carries ...".
Section 12: s/Janey C. Hoe/Janey C. Hoe/
