NAME of I-D

http://search.ietf.org/internet-drafts/draft-tsenevir-8021qmpls-01.txt

(My new contact information tissa@force10networks.com)

SUMMARY:

This I-D presents a discussion on possible methods for extending Layer 2 
Virtual LANs across MPLS networks through the use of CR-LDP or RSVP. The key

focus of the document is present methods to implement Ethernet like services

across MPLS networks.  In this document we present required encapsulation 
format, signaling methods and implementation of fully meshed back-end to 
emulate the broadcast nature of Local Area Networks.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK

CCAMP/PPVPN

WHY IS IT TARGETED AT THIS WG

CCAMP charter include " Define signaling protocols and measurement protocols

such that they support multiple physical path and tunnel technologies (e.g. 
O-O and O-E-O optical switches, ATM and Frame Relay switches, MPLS, GRE) 
using input from technology-specific working groups such as MPLS, IPO, 
etc.".  The presented ID discuss extend Ethernet like connectivity across 
MPLS networks. Hence the work presented in the document are within the scope

of the CCAMP charter.

On the other hand the methods presented in this ID are key to construct
Layer 2 NBVPN, in that aspect the work defined here is within the broader
scope of PPVPN WG

JUSTIFICATION

Increasing number of service providers are offering Ethernet services to the

customers. In the core of the network IP or Sub-IP technologies are used. 
Ethernet services provided to customers are in general VPN service having 
multi-points of service access (as opposed to point-to-point).

The methods presented in this ID helps to build many-to-many  virtual 
Ethernet topologies across MPLS clouds.  The work presented here is key to 
implement Layer 2 NBVPN using MPLS backbones.
