Hello, In SIGCOMM 2011 DevoFlow<http://www.hpl.hp.com/personal/Praveen_Yalagandula/papers/SIGCOMM2011-DevoFlow.pdf>paper, authors state that their hardware switch implementation [ProCurve 5406zl] is capable of roughly 275 flow setups per second. (Which is also in line with the OSDI 2010 FlowVisor<http://www.openflow.org/wk/images/2/25/Flowvisor.pdf>paper.) OTOH, [I don't know if this is an apples to apples comparison but...] Ben Pffaf from Nicira reported<http://openvswitch.org/pipermail/discuss/2011-May/005242.html>that he gets results in the order of 200,000 unique flow setups per second using Open vSwitch. What is the current state of the modern (physical and virtual) OpenFlow switches' flow setup rates? While making any calculations for planning purposes, what is the recommended upper bound on the flow setup rate that an OF switch can handle?
Best.
