Title : Implementing MLPP for Voice and Video in the Internet Protocol Suite
Author(s) : F. Baker, J. Polk

The Defense Information Systems Agency of the United States
Department of Defense, with its contractors, has proposed a service
architecture for military (NATO and related agencies) telephone
systems. This is called the Assured Service, and is defined in two
documents: "Architecture for Assured Service Capabilities in Voice
over IP" and "Requirements for Assured Service Capabilities in Voice
over IP". Responding to these are two documents: "Extending the
Session Initiation Protocol Reason Header to account for Preemption
Events", "Communications Resource Priority for the Session Initiation
Protocol".
What remains to this specification is to provide a Call Admission
Control procedure and a Per Hop Behavior for the data which meet the
needs of this architecture. Such a CAC procedure and PHB is
appropriate to any service that might use H.323 or SIP to set up real
time sessions. These obviously include but are not limited to Voice
and Video applications, although at this writing the community is
mostly thinking about Voice on IP and many of the examples in the
document are taken from that environment.
In a network where a call that is permitted initially and is not
denied or rejected at a later time, call and capacity admission
procedures performed only at the time of call setup may be
sufficient. However in a network where sessions' status can be
reviewed by the network and preempted or denied due to changes in
routing (when the new routes lack capacity to carry calls switched to
them) or changes in offered load (where higher precedence calls
supercede existing calls), maintaining a continuing model of the
status of the various calls is required.

In the body type:

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.
