As a provider, Expedient has to balance five core resources: compute, storage (capacity), storage (performance), network I/O, and memory. VM-to-VM (on the same host) via a hardware-based virtual switch in an SR-IOV network interface card (NIC). In this case, the switching is done in hardware in the SR-IOV NIC.

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? , about what SDN meant when it was first coined.
