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.
