Title : NSIS PCN-QoSM: A Quality of Service Model for Pre-Congestion Notification (PCN)
Author(s) : M. Arumaithurai

This document describes a Quality of Service model (QOSM), for
networks that support the use of the Controlled load service over a
Diffserv cloud using pre-congestion notification. Ths is a technique
to perform admission control in a Diffserv network by measuring the
congestion level in a domain. New flows are admitted only if the
current congestion level is below the allowed threshold. When the
controlled load in a domain exceeds a certain threshold, the egress
prompts the ingress to pre-empt certain flows. This proposal is
based on the proposal made by B.Briscoe et al., for the extension of
RSVP to support the Controlled load service over a Diffserv cloud
using pre-congestion notification.

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
