this is a scaling problem, and one which points to the need to not do 'all of one thing' ('all nfv will solve us!') you may still need other methods to load balance or deal with loads which are higher than the nfv platform(s) can deal with properly. In some sense this is the same problem as trying to push too many pps through a linecard which you know has a limit lower than line-rate.
out of the control plane and they are not congruent. we've had too manylessons debugging this situation (datakit, atm, ...).
seperation of data/control plane ... does require knowledge about what you are doing and has clear implications on toolling, troubleshooting, etc. To some extent this mirrors anycast dns deployment problems. "I made a much more complex system, though from the outside perhaps it doesn't appear any different." be prepared for interesting times.
Sdn is like authoritarianism and divine creation rolled up into one and sold at 20% premium to easily duped telco types that want to travel to endless conferences
Sure, you have to know what you are doing/buying... magic doesn't exist in this space.
beyond that, i am not sure i see that much difference whether it's a YFRV or a SuperMicro. but i sure wish bird and quagga had solid is-is, supported communities, ... randy
