Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org>, dime mailing list <email@example.com>, dime chair <firstname.lastname@example.org> 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. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-dime-diameter-qos-15.txt
Technical Summary 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. Document Quality 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. Personnel Victor Fajardo is the document shepherd for this document. Dan Romascanu is the shepherding AD.
