NAME OF I-D:

http://www.ietf.org/internet-drafts/draft-malis-sonet-ces-mpls-04.txt

SUMMARY

The original IP-based "Virtual Private Network" was a set of 
customer-premise IP routers interconnected by TDM private lines leased from 
service providers. This method of creating an IP VPN is still widely in 
use. This document allows the emulation of this style of VPN over an IP 
backbone, when using the procedures described in 
draft-martini-l2circuit-trans-mpls-05.txt, and is a logical extension of 
the L2VPN work in the PPVPN working group.

A TDM encapsulation which is independent of the tunneling methodology is 
defined, and the way in which this is further encapsulated inside an MPLS 
frame is defined.

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

As noted above, this applies to the L2VPN work in the PPVPN WG.  It also 
applies to the circuit emulation work in the pwe3 working group.

WHY IS IT TARGETED AT THIS WG

This was targeted to the PPVPN WG because it applies to one of the work 
items called  out in the PPVPN WG charter, L2VPNs.

JUSTIFICATION

This draft directly supports one of the work items in the PPVPN WG charter, 
L2VPNs.
