Dear TCPM WG,

We just submitted a new revised version of the TCP ACK Rate Request (TARR)
Option. We have aimed to incorporate the feedback received in IETF 114, and
from the mailing list.

Summary of updates:

- Reduced the main option format from 6 bytes back to 5 bytes. In this
version, the maximum value of R is 127. (The reserved bit might be used to
enable a different encoding for R, e.g., to support larger values if deemed
necessary in the future.)
- Added Appendix A on the relation between this draft and RFC 5690.
- Minor updates (added reference to RFC 8174 and related text, minor
corrections, etc.).

Comments are welcome!

Thanks,

The authors

Abstract:
   TCP Delayed Acknowledgments (ACKs) is a widely deployed mechanism
   that allows reducing protocol overhead in many scenarios.  However,
   Delayed ACKs may also contribute to suboptimal performance.  When a
   relatively large congestion window (cwnd) can be used, less frequent
   ACKs may be desirable.  On the other hand, in relatively small cwnd
   scenarios, eliciting an immediate ACK may avoid unnecessary delays
   that may be incurred by the Delayed ACKs mechanism.  This document
   specifies the TCP ACK Rate Request (TARR) option.  This option allows
   a sender to request the ACK rate to be used by a receiver, and it
   also allows to request immediate ACKs from a receiver.
