Hi Justin,
Based on my packet traces, each flow installation packet takes about
72B. We are trying to periodically change the flow entries at all edge
switches. We were look at the worst case of pushing 2k entries to all
edge switches at once.

No, there is not. I'm not sure I understand the concern, though. There's
maybe a few dozen bytes of overhead per message. Of the criticisms I've heard
about OpenFlow, that particular bit of overhead has not been one of them. Have
you seen it be a problem in practice?

Is it possible to install multiple distinct flow entries in one openflow
message. Right now, I am currently sending a message for each flow entry that
I want to install, however, I want to combine multiple flow entries in one
message in an attempt to reduce the network footprint.
