A new IETF working group has been proposed in the Routing Area. The IESG has not made any determination as yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg@ietf.org) by June 22nd. +++ Layer 1 Virtual Private Networks (l1vpn) ---------------------------------------- Current Status: Proposed Working Group Chair(s): TBD Routing Area Director(s): Bill Fenner <fenner@research.att.com> Alex Zinin <zinin@psg.com> Routing Area Advisor: Alex Zinin <zinin@psg.com> Technical Advisor(s): TBD Secretary(ies): TBD Mailing Lists: General Discussion: l1vpn@ietf.org To Subscribe: https://www1.ietf.org/mailman/listinfo/l1vpn Archive: http://www.ietf.org/mail-archive/web/l1vpn/index.html 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.
