Hi All,
This is the new version of the draft-ietf-l2sm-l2vpn-service-model.
Most of the changes address the comments received during the L2SM interim meeting and are reported below (and also summarized in the Appendix A). 

   Changes in v-(02) include:

   o  Fix figure 3 and figure 4 in section 3.4 to apply IEEE802.3 on the
      segment between C and CE and apply IEEE802.1Q on the segment
      between CE and PE.

   o  Update Signaling Option section and add L2TP support and classify
      the signaling option type into BGP-L2VPN, BGP-EVPN, LDP-PWE, L2TP-
      PW.

   o  Add Multicast Support in section 5.2.13, section 5.10.3 and move
      the text in BUM Storm Control section into section 5.10.3.

   o  Add new section 5.3.1, section 5.4, section 5.5, section 5.6,
      section 5.7, section 5.8, section 5.11to explain the usage of

   o  Add new section 5.1 and 5.14 to allow augmentation and external ID
      References.

   o  Add new section to discuss inter-AS support and inter-provider
      support with NNI and EVC, OVC.

   o  Update Service Section 5.10 and define four type for svc-input-
      bandwidth and svc-output-bandwidth and add guaranteed-bw-percent
      parameter and related description.

   o  Add extranet VPN support.

   o  Remove duplicated parameters from cloud access.

   o  Move L2CP control plane protocol parameters under connection.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the L2VPN Service Model of the IETF.

        Title           : A YANG Data Model for L2VPN Service Delivery
        Authors         : Bin Wen

Abstract:
   This document defines a YANG data model that can be used to configure
   a Layer 2 Provider Provisioned VPN service.

   This model is intended to be instantiated at management system to
   deliver the overall service.  This model is not a configuration model
   to be used directly on network elements, but provides an abstracted
   view of the Layer 2 VPN service configuration components.  It is up
   to a management system to take this as an input and generate specific
   configurations models to configure the different network elements to
   deliver the service.  How configuration of network elements is done
   is out of scope of the document.

   The data model in this document includes support for point-to-point
   Virtual Private Wire Services (VPWS) and multipoint Virtual Private
   LAN services (VPLS) that use Pseudowires signaled using the Label
   Distribution Protocol (LDP) and the Border Gateway Protocol (BGP) as
   described in RFC4761 and RFC6624.
