“ Before buying an OpenFlow-based data center network, figure out what the vendors are doing (they will probably ask you to sign an NDA, which is fine), including:
*What are the mechanisms used to reduce forwarding state in the OpenFlow-based network core?
* What’s the actual packet format used in the network core (or: how are the fields in the packet header really used?)
* Will you be able to use standard network analysis tools to troubleshoot the network?
* Which version of OpenFlow are they using?
* Which proprietary extensions are they using (or not using)?
* Which switch/controller combinations are tested and fully supported? „
