 Subject:     Reply to Liaison Statement on L1VPNs

Dear Mr. Carugi,

Thank you for your liaison statement COM13-LS23 dated 3-12 February
2004 on the subject of Layer One VPNs and related work within Study
Group 13.

Thanks also to the members of Study Group 13 Question 11 for their
work on draft-takeda-l1vpn-framework-00.txt which represents so clearly
the motivations for L1VPNs, the high level (service level) requirements,
and the architectural models that might be used to build L1VPNs.

Members of the CCAMP working group have expressed a considerable
interest in this work and we are keen to pursue a working relationship
with SG13 to advance the description of the functional requirements,
assess current protocols for suitability, and develop any protocol
extensions that may be necessary.

Some feedback on draft-takeda-l1vpn-framework-00.txt has already been
made on the CCAMP mailing list and we know that the authors of the
draft are aware of the comments.  Hopefully this is valuable input and
will be taken back for discussion in Q.11 where appropriate.

In order to further facilitate the discussion of L1VPN within the
IETF, we have started a new mailing list designated for L1VPN emails
only.  In keeping with all IETF mailing lists, this list is open to
all and we would welcome active participation from SG13 delegates and
attendees, and from anyone else who can contribute in this area.

We anticipate that initial discussions will focus on
draft-takeda-l1vpn-framework-00.txt, but that we will move on to an
analysis of the short-comings of existing IETF protocols in the
delivery of L1VPNs.

To join the mailing list please visit

also be archived and can be read on the Web at

Sincerely,
Kireeti Kompella & Adrian Farrel, CCAMP WG chairs
