I can BGP peer with SDN !
Nice. Internet scale ?nope
IPv6, ACLs, OSPF, ISIS ?
nopetrace route
sort of..ICM
P, Ping, QoS
So… Are we ready to
deploy SDN then ?Do or Do Not. There is no try.

Distributed Routers only make sense
when there is no other solution. Too often SDN encourages us to be like a
“data centre” for non-datacenter problem

Make your hardware vendor
accountable for the whole solution. No M

Switch. Have a nice day.” Operators
are not Developers. 4.
