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?

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). ONP fits into this picture by performing VTEP functions in hardware (at line rate). Some of these services naturally should run on the top-of-rack (ToR) switch, like load balancing or security services.

Graphics processing is one such area with huge computational requirements, but where each of the tasks is relatively small and often a set of operations are performed on data in the form of a pipeline. The different stages were then load balanced across the available units. Â The input data is often organized as a Grid.
