According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware. Or virtualized firewalls? What about NX-OS, JUNOS, or EOS? Are these SDN too?

In this case, the switching is done in hardware in the SR-IOV NIC. Rodriguez goes over the reasons that Expedient is evaluating FCoE for their data center.
