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. What about virtualized load balancers? What about NX-OS, JUNOS, or EOS?

Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture). Note that there are trade-offs as a result.)

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). Recep talks about how the predominant architecture for network virtualization involves the use of overlay networks created and managed at the edge by virtual switches in the hypervisors. So how does this work?
