A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Congestion Notification Process for Real-Time Traffic
Author(s) : J. Babiarz, et al.
Filename : draft-babiarz-tsvwg-rtecn-01.txt
Pages : 13

This memo specifies the usage of Explicit Congestion Notifications
(ECN) markings for real-time flows that use UDP, such as voice, video
conferencing and multimedia streaming. This memo tries to reuse as
much of RFC 3168, "The Addition of Explicit Congestion Notification
to IP", as possible. However, we found it necessary to introduce new
ECN semantics for real-time UDP flows. For real-time UDP flows, this
memo describes how the network performs ECN marking when congestion
is experienced, but it is left up to the application designers to
define how end systems should react to ECN bit marking. For
illustration purpose, an example is provided showing how ECN for
real-time UDP flows can be used for admission control of VoIP flows.

In the body type:
"FILE /internet-drafts/draft-babiarz-tsvwg-rtecn-01.txt".
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.
