This work is seen as closely related to DSL Forum’s WT-147 activity. Our group’s charter, details of which can be found at http://www.ietf.org/html.charters/ancp-charter.html, addresses the following ANCP use-cases: 1. Dynamic Access Loop Attributes ANCP will provide a mechanism to communicate dynamic access-loop attributes from the Access Node (AN) to the Network Access Server (NAS). 2. Access Loop Configuration ANCP will allow a NAS to send loop-specific configuration information to an AN based on the results of subscriber authentication and authorization (e.g., after AAA responses have been received at the NAS). 3. Remote Connectivity Test ANCP will allow a remote procedure for a local loop connectivity test to be triggered from the NAS with results communicated back to the NAS. 4. Multicast ANCP will provide a mechanism to communicate the necessary information exchange between the AN and NAS so as to allow the AN to perform subscriber bound multicast group replication in line with the subscriber's policy and configuration, and also allow the NAS to follow each subscriber's multicast group membership. Our currently defined goals foresee the group working towards an overall protocol “Framework and Requirements” internet-draft, followed by ANCP protocol specification and MIB definition internet-drafts. During the IETF 66 meeting held in Montreal on July 10-15, we had the opportunity to hold our first official Working Group meeting. The agenda, contribution materials and minutes can be found at: https://datatracker.ietf.org/public/meeting_materials.cgi?meeting_num=66 The Working Group has achieved progress by agreeing to adopt draft-ooghe-ancp-framework-00 (http://www.ietf.org/internet-drafts/draft-ooghe-ancp-framework-00.txt) as the Work Group’s Internet-Draft protocol requirements document. Up-to-date information on ANCP Internet-Drafts and RFCs can always be found at http://tools.ietf.org/wg/ancp We invite you to keep us informed of progress of your work in the WT-147 area. We also encourage interested DSL Forum members to join and participate in our Work Group’s discussions and activities taking place on the ancp@ietf.org mailing list and during official WG meetings. Details on how to subscribe to the mailing list can be found on our charter page. The next tentative meetings of the IETF ANCP WG are: - Nov 5-10, 2006 – IETF 67 – San Diego, California, USA - Mar 18-23, 2007 – IETF 68 – TBD, Europe.
