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.
