Another great question I got from David Le Goff:
So far, SDN is relying or stressing mainly the L2-L3 network programmability (switches and routers). Why are most of the people not mentioning L4-L7 network services such as firewalls or ADCs. Why would those elements not have to be SDNed with an OpenFlow support for instance?
To understand the focus on L2/L3 switching, let’s go back a year and a half to the laws-of-physics-changing big bang event.
