Title : Session setup with media authorization
Author(s) : L. Hamer, B. Gage
Filename : draft-hamer-sip-session-auth-00.txt
Pages : 23

Current proposals dealing with authorization of media streams for
multimedia services like IP telephony and video assume a pre-
established relationship between elements of the network (e.g.
session managers, edge routers, policy servers and end hosts). In
some environments, however, such pre-established relationships may
not exist either due to the complexity of creating these
associations a priori (e.g. in a network with many elements), or due
to the different business entities involved (e.g. service provider
and access provider), or due to the dynamic nature of these
associations (e.g. in a mobile environment).
In this document, we describe scenarios where there is no pre-
established relationship between entities and describe mechanisms
for exchanging information between network elements in order to
authorize the use of resources for a service and to co-ordinate
actions between the session and bearer control planes.

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.
