Title : SDPng Transition

The Session Description Protocol (SDP) is today widely used in the
Internet to announce as well as negotiate multimedia sessions and
exchange capabilities. Having originally been designed for session
announcements only, as opposed to announcements and capabilities
negotiation announcements, native SDP lacks numerous features to be
applicable in many session scenarios. Numerous extensions have been
developed to circumvent SDP's shortcomings -- but they have also
repeatedly shown its inherent limitations. A successor protocol --
termed 'SDPng' for the time being -- is developed to address the
aforementioned needs of Internet applications in a more structured
manner. With the huge installed base of SDP-based applications, a
migration path needs to be developed to move from SDP to SDPng over
time. This document outlines how this migration can be achieved: in
general as well as for the various IETF control protocols that
potentially make use of SDP and SDPng.

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.
