This might interesting for the l1/l2/l3 vpn and vrrp people.
You may have received the below email some days ago. The feedback to this email
was very positive, i.e., there has been feedback from interested researchers in
the US, Canada, Asia, and Europe.
If you are interested you can

The meeting at the IETF (BAR BOF style in IETF speak) is on
WEDNESDAY, March 12, 2008
1510-1700 Afternoon Session II and beyond
Meeting room: to be announced.
The agenda will be posted on the web site.
Several research initiatives in the area of "Future Internet" have recently
started in the US, Europe, and Asia. Amongst them are, for instance, GENI/FIND
, 4WARD , Trilogy , and NICT's New Generation Network projects .
All these efforts possible lead to an internetworking architecture with the
support of network virtualization that significantly provides more flexible
features than the current Internet.
Network virtualization follows the same principle as any known computer
virtualization technology, such as virtual memory, virtual hard disk, virtual
screens, etc. It is always an abstraction from a real resource, hiding the
underlying complexity (cf. ). But even if virtualization is an integral part
of today's computing technology (which is close to communication technology),
it is still lacking a counterpart in the Internet architecture. Current
proposals discuss possible virtualization techniques (e.g. ) on top the
today's Internet (also past techniques such as MBONE and related), or more
general on a substrate . The clean slate approach  also considers network
virtualization as an integral part of the future Internet.
However, all of these activities are bound to each local community, but there
is no larger, international discussion (apart from some smaller meetings, e.g.,
between Ambient Network and GENI/FIND . All of currently discussed ideas
are somewhat heading towards different directions (especially different between
academia and industry research). Thus it would be beneficial to have a venue
for discussing ideas w.r.t. network virtualization as a new means for the
Internet today, as transition path to new technologies, or as integral part of
the future Internet would be beneficial. Researchers from US, Europe, and Asia
could discuss what exactly network virtualization could bring as benefit, how
it is impacting the Internet, and what might be the impact to the Internet
Therefore, I have in mind a venue where researchers can discuss their ideas
(w/o considering standardization/interfaces definitions yet) and try to shape a
way forward for future Internet activities in this field. The Internet Research
Task Force (IRTF) can be good place to give this a home.
The intention of this email is to first gather community feedback about whether
researchers do find this idea of creating an IRTF research group (RG) appealing
enough and have energy enough to actively participate in such a group.
The envisioned main goals of such a RG in the area of network virtualization
- a discussion venue without standardization or any other limiting boundaries
- bringing together the right people from US, Asia and Europe
Open issues to be addressed by this RG are, but not limited to:
- impact of network virtualization to the Internet architecture as such,
Internet devices (routers and hosts), and applications running in the Internet;
- can network virtualization solve the ossification issue (cf.  of the
Internet or is it just shifting problems from one place to another;
- are overlays one possible answer to network virtualization;
- are the current testbed initiatives (e.g., PlanetLab, OneLab, etc) a first
answer to network virtualization?
Interested people are requested to reply to this email and if possible to meet
at the upcoming IETF meeting (IETF#71) in Philadelphia to discuss further
steps. A possible meeting slot during the IETF meeting would be Wednesday after
the IETF Operations and Administration Plenary. However, I'm open for
