TISPAN Liaison

A liaison with ETSI TISPAN regarding the Diameter Auditing work has to be established. The requirements draft can be found here: http://tools.ietf.org/wg/dime/draft-bodin-dime-auditing-reqs-01.txt

ITU-T Liaison

The chairs have received a liaison document from the ITU-T with the title: "RFC 3588 - Requirement of Session State Machine for Diameter Server Initiated Session"

Here is the extracted text:

" ITU-T study group 11 question 5 would like to acknowledge the versatility of the Diameter Protocol for its suitability over many interfaces in Next Generation Networks (NGN). The group has decided to use the protocol (as one of the alternatives) for the Rs and Rw interfaces in the Resource and Admission Control Function (RACF) part of the NGN. The latest drafts of the corresponding protocol specification documents for the Rs and Rw interfaces are Q.3301.1 and Q.rcp3.3 (T05-NGN.GSI-DOC-0127) respectively. The Rw interface exists between Policy Decision Physical Entity (PD-PE) and the Policy Enforcement Physical Entity (PE-PE) where PD-PE acts as the diameter server and the PE-PE acts as the diameter client. For the pull mode of operation, the PE-PE establishes a diameter session and the corresponding state machine is covered in section 8.1 of the RFC 3588. But for the push mode there is a requirement that the PD-PE, acting as a diameter server, initiates the session for which no state machine has been provided in the RFC. The RFC, however, in the last paragraph of its section 8.8 indicates indirectly that there is possibility of the session initiation by the server.

ITU-T study group 11 question 5 would like to look for comments and enhancement of the diameter protocol to clearly specify the session state machine for the case of diameter server initiated session. "

WG Recharting (December 2006)

The charted items are out-of-date and the current working group status needs to be reflected in the charter page.

(*) See http://www1.ietf.org/mail-archive/web/dime/current/msg01027.html

Currently, the following items are listed and per December 2006 the following action items have been identified:

Diameter API

Mar 2006 Submit Diameter API to IESG as an information RFC

The working group last call of the Diameter API has finished on Monday, December 4th.

Diameter URI

May 2006 Submit Diameter URI to IESG as an information RFC

As discussed during IETF #67 it was suggested to remove this item from the charter page.

Diameter QoS^?

Sep 2006 Submit Diameter QoS^? Application to IESG as a Proposed Standard

A small group of authors started with the draft update with Glen Zorn as the document editor.

Suggested milestone date: July 2007

Diameter Application Design Guidelines

Sep 2006 Submit Diameter Application Design Guidelines to IESG as an informational RFC

Suggested new milestone date: Sep. 2007

Diameter Base

Jan 2007 Submit Diameter Base to IESG as a Draft Standard

The Diameter Base Draft needs to be submitted as working group item.

Suggested milestone date for the revised Diameter Base document: July 2007

Diameter Mobility

Currently a milestone is missing (due to some sort of update failure of the webpage). We need to add something and here is the proposal: Aug 2007

Adding New Work

A number of IETF DIME working group members have expressed interest in starting new work. As indicated by the ADs, no new work will be added before making progress with the current items.

As part of the recharting process a ranking of new work items should be compiled. This ranking should serve as a suggestion on what to add in the future.

Working Group Secretary (Dec. 2006)

Victor Fajardo was elected as the WG secretary.
