> Description of Working Group:
> The L1VPN Working Group's task is to specify mechanisms necessary for
> providing layer-1 VPN services (establishment of layer-1 connections
> between CE devices) over a GMPLS-enabled transport service-provider
network.
>
> The following two service models will be addressed:
>
> 1. Basic mode: the CE-PE interface's functional repertoire is limited to
> path setup signalling only. Provider's network is not involved in
> distribution of customer network's routing information.
>
> 2. Enhanced mode: the CE-PE interface provides the signaling
> capabilities as in the Basic mode, plus permits limited exchange of
> information between the control planes of the provider and the customer
> to help such functions as discovery of reachability information in
> remote sites, or parameters of the part of the provider's network
> dedicated to the customer.
>
> The WG will work on the following items:
>
> 1. Framework document defining the reference network model, L1VPN
> service model, fundamental assumptions, and terminology.
>
> 2. Specification of the L1VPN signaling functionality between the
> customer and the provider network to support the basic mode.
>
> 3. Specification of the L1VPN signaling and routing functionality within
> the provider network to support the basic mode.
>
> 4. OAM features and MIB modules and/or extensions required for the basic
> mode.
>
> 5. Specification of the L1VPN signaling and routing functionality
> between the customer and the provider network to support the extended
mode.
>
> 6. Specification of the L1VPN signaling and routing functionality within
> the provider network to support the extended mode.
>
> 7. OAM features and MIB modules and/or extensions required for the
> extended mode.
>
> 8. Applicability guidelines to compare the basic and extended modes.
>
> At this point the WG will address the single-AS scenario only. The
> multi-AS/provider scenario may be considered in future.
>
> Protocol extensions required for L1VPN will be done in cooperation with
> MPLS, CCAMP, OSPF, IS-IS, IDR, L3VPN, and other WGs where necessary.
>
> L1VPN WG shall also cooperate with ITU-T SG13 through the established
> IETF process, and use documents Y.1312 and Y.1313 (describing L1VPN
> requirements and network architectures) as input to its design process.
> The documents will be available at the IETF liaison web-site.
>
> Goals and Milestones:
> Sep 05    Submit first Internet Draft of L1VPN framework
> Sep 05    Submit first Internet Drafts of basic mode specifications
> Dec 05    Submit first Internet Drafts of MIB modules for basic mode
> Apr 06    Submit basic mode specifications to IESG for publication as
Proposed

> Jun 06    Submit first Internet Drafts of enhanced mode specifications
> Aug 06    Submit MIB modules for basic mode to IESG for publication as
