Re: [vnrg] FlowVisor : A Network Virtualization Layer



Hi Rob-

Glad to see you are on this list.  FYI, the research group meeting is scheduled for Friday 0900 - 1130 Beijing time.  Meetings are in general audiocast with jabber feedback channels so you are welcome to listen and participate if you'd like.  See http://www.ietf.org/meeting/79/remote-participation.html.  In fact, modulo the chairs' approval, I believe it is not too late to request agenda time for yourself and webex is available for remote presentation.

Hello,


Apologies that I was not able to attend the working group meeting, but
thanks for the interest on FlowVisor.  I flipped through the slides at

http://www.ietf.org/proceedings/79/slides/VNRG-0.pdf

and at least from the slides (I'm not sure how the
presentation/discussion about these slides went) I think there might
be a few things that need clarification:

In most of the flowvisor literature, we're very careful to describe
this as "network *slicing*" as opposed to "network virtualization".
The key differences (as brought out in the slides) is that current,
FlowVisor does not support:

- two slices controlling the same virtual address space (e.g.,
10.0.0.0/24) but the flowvisor rewriting them to different physical
addresses
- network topologies that are independent of the physical topology
(currently FlowVisor is restricted to subsets of the physical
topology)

Both of these points are limits of the current implementation, but not
of the design, and my thoughts for the future are to take FV towards
implementing these points.

If anyone is interested in learning more about FlowVisor or its
deployments as part of GENI, please let me know.

Thanks again for the interest,

- Rob
