Subject: Protocol Action: 'Diameter Quality of Service Application' to Proposed Standard
The IESG has approved the following document:
- 'Diameter Quality of Service Application '
<draft-ietf-dime-diameter-qos-15.txt> as a Proposed Standard
This document is the product of the Diameter Maintenance and Extensions Working Group.
The IESG contact persons are Dan Romascanu and Ron Bonica.

The document specifies a framework, messages and AVPs for
performing QoS authorization operations. It defines a QoS Diameter
application that allows network elements (QoS aware routers) to
interact with Diameter servers to authorize QoS request. It
has been designed to operate in both 'Push' or 'Pull' mode
where QoS authorization state is either sent to the network
element pro-actively (Push) or the network element directly
request QoS authorization from the Diameter server.
A set of commands and AVPs has been defined to support both
operating modes. A supplemental state machine that augments
the Diameter base protocol (RFC3588) state machine has also been
defined to cleanly support Push mode operations. The document
also describes QoS authorization session establishment as well
as re-authorization. It provides examples and call flows that
describes how QoS authorization can be used other applications
(e.g. NSLP, SIP).
Working Group Summary
There was consensus in the WG to publish the document.
The document has been sent for review to NSIS and relevant QoS folks.
This document defines a core component of a Network Operators QoS
architecture and thus have gone through a long review process
both within DIME WG and outside of it. It has also traversed
several re-start iteration before its current acceptable state.
Victor Fajardo is the document shepherd for this document. Dan
Romascanu is the shepherding AD.
