Thomas, Thanks for your comments. Please see below. Matthew "Haag, T" <Thomas.Haag@t-sy stems.com> To Matthew BOCCI/GB/ALCATEL@ALCATEL 23/05/2006 11:18 cc l2cp@ietf.org Subject AW: [L2CP] Updated LC charter Matthew, Please see inline my comments: ? Necessary Terminology: Access Node (AN) - Network device, usually located at a service provider central office [Th. Haag] or street cabinet, that terminates DSL connections from Subscribers. Often referred to as a Digital Subscriber Line Access Multiplexer (DSLAM) ? The ANCP WG will address the following four use-cases: 1. Dynamic Access Loop [Th.Haag] attributes Various queuing and scheduling mechanisms are used in access networks to avoid congestion while dealing with multiple flows and distinct QoS profiles. Communicating the access-loop [Th.Haag] status and attributes and current DSL synchronization rate between the AN and Subscriber up to the NAS is desirable, particularly when the NAS is providing QoS for individual flows and subscribers. ANCP will provide a mechanism to communicate dynamic access-loop [Th.Haag] attributes from the AN to the NAS. ? Non-Goals: ANCP is an IP-based protocol that operates between the AN and NAS, over a DSL access and aggregation network. It will not address [Th.Haag] network management operation of circuits or connections in the access and aggregation network itself [Th.Haag] but will not exclude use case relevant aspects of access and aggregation. MB> We should not loose the fact that ANCP is not a signalling protocol for the establishment of ATM or Ethernet connectivity in the aggregation network. The current use cases do not require this, so I'm not sure that I understand your point. The focus of this WG is on one very specific application space. While the design of the protocol should be general as to not preclude other uses in the future should a need arise, it is not a goal of this WG to address specific requirements outside of DSL access and aggregation networks. ? Keeping in mind the following comments of the minutes I propose the changes regarding Non-goals. Mark Townsley: - we should not even precule other use of the protocol in other areas?. Mark Townsley: Scoping of that group is driving to solve existing problem. We should use good engineering to build things to allow future problems but we should not try to solve everything from the start.

Mai 2006 18:20 An: l2cp@ietf.org Betreff: [L2CP] Updated LC charter Folks, We received a number of comments back from our ADs on the draft charter, following the last call that we issued a few weeks ago. Please find attached a new revision of the charter that incorporates these comments. Please post any comments to the list by this Friday (26th May). This will be taken to the IESG once once the list has agreed to the revisions. best regards, Matthew (See attached file: ANCP-charter-220506.txt) _______________________________________________ L2cp mailing list L2cp@ietf.org https://www1.ietf.org/mailman/listinfo/l2cp
