Fwd: I-D Action:draft-ietf-dccp-rfc3448bis-05.txt

[Sally Floyd <sallyfloyd@xxxxxxx>]

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

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.
