I have submitted a revised version of
draft-ietf-dccp-rfc3448bis-05.txt.
The changes from -04 are as follows:
* Added a mechanism for decaying the value in X_recv_set
following a loss event in a data-limited interval, and
restricting recv_limit to "max (X_recv_set)" for the next
RTT. Also added a discussion to Appendix C of the
response to a loss during a data-limited period.
Following feedback from Gorry and Arjuna.
* Removed a restriction in step 4) of Section 4.3 about
checking if the sender was not data-limited, when the sender
has been in initial slow-start. It is no longer needed.
Feedback from Arjuna.
* Added pseudocode to Section 8.2.1 on "Determining If an
Interval Was a Data-limited Interval", fixing a bug in the
procedure. Feedback from Arjuna.
Many thanks to Gorry and Arjuna for feedback, in particular about
dealing with loss events in data-limited intervals.
I think this is now ready for Working Group Last Call
(though I note that I have thought this before...)

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Datagram Congestion Control
Protocol Working Group of the IETF.
Title : TCP Friendly Rate Control (TFRC): Protocol
Specification
Author(s) : U. London, et al.
Filename : draft-ietf-dccp-rfc3448bis-05.txt
Pages : 64
Date : 2008-02-25
This document specifies TCP-Friendly Rate Control (TFRC). TFRC is a
congestion control mechanism for unicast flows operating in a best-
effort Internet environment. It is reasonably fair when competing
for bandwidth with TCP flows, but has a much lower variation of
throughput over time compared with TCP, making it more suitable for
applications such as streaming media where a relatively smooth
sending rate is of importance.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
