Directorate people-

Alex,
Here's your reading :-)

Framework
http://www.ietf.org/internet-drafts/draft-takeda-l1vpn-framework-03.txt
This is really well cooked.
Apart from editorial, the authors think there is nothing else to do.

Applicability (of protocols to meeting the framework)
http://www.ietf.org/internet-drafts/draft-takeda-l1vpn-applicability-02.txt
This needs another pass by the authors to fill in some blanks. But it is
pretty well advanced.

Specific solution
http://www.ietf.org/internet-drafts/draft-ouldbrahim-ppvpn-gvpn-bgpgmpls-06.txt
This draft has been around for the longest time.
Conceptually it is done.
I believe there is an implementation

Second protocol solution model
http://www.ietf.org/internet-drafts/draft-ietf-ccamp-gmpls-overlay-05.txt
The "GMPLS UNI" draft specifically mentions L1VPNs and solves some of the
models.
For other models it might need some extensions.
This draft is "pending announcement"


Questions?
Adrian

Hi Alex,

I am Tomonori Takeda of NTT, who has been participating in IETF (especially 
CCAMP) for a while. Thank you very much for discussing with me L1VPN 
related topics several times.

As you may know, I was a contributor to the ITU-T recommendations on 
L1VPNs, but I thought it would be best if the protocol extensions were done 
within the IETF, so I worked to present the requirements and architecture 
as Internet-Drafts. I am currently the editor of the framework draft and 
the applicability analysis draft that explains how existing protocols can 
be used to provide L1VPNs.

I would appreciate your kind offer to read those L1VPN related I-Ds, as you 
mentioned in the previous IETF meeting. I am wondering it might be helpful 
to contact you now so that the I-Ds are cleardy understood. I would be more 
than happy to discuss any issue, and/or provide any clarification.

Two I-Ds are as follows.
http://www.ietf.org/internet-drafts/draft-takeda-l1vpn-framework-03.txt
http://www.ietf.org/internet-drafts/draft-takeda-l1vpn-applicability-02.txt
