Dear TCPM WG,

Please find below the main pointers to the last update of the TCP ACK Rate
Request (TARR) draft.

The main updates are the addition of Appendix C, and a related change in
Section 3.1 (sender behavior), both on the topic of using TARR in the
presence of elements (other than the TCP endpoints) that aim to modify the
TCP ACK rate.

Comments are welcome!

Cheers,

The authors

Internet-Draft draft-ietf-tcpm-ack-rate-request-05.txt is now available. It
is
a work item of the TCP Maintenance and Minor Extensions (TCPM) WG of the
IETF.

   Title:   TCP ACK Rate Request Option
   Authors: Carles Gomez
            Jon Crowcroft
   Name:    draft-ietf-tcpm-ack-rate-request-05.txt
   Pages:   19

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.
