What?
SDN is a poor alternative for those who can't construct a
network with fully automated QoS guarantee.
Even with SDN, QoS guarantee implies QoS routing requiring
dedicated routing table entry for each flow, which will not
shrink but bloat routing tables regardless of whether you
call it FIB or not.
I'm going to have to "what?" you right back there. You don't need to program each individual flow, just each FEC.
SDN does not imply QoS routing, it's just one aspect of it. Some use it for classifying guest traffic etc.
