Virtual Workloads Continue Increasing

Network layer merged with SDN

NV/SDN/NFV

• NV (Network Virtualization): Using overlaying technique to make a physical network

appear as multiple logical ones, achieving isolation in a multi-tenant (Cloud).

• SDN (Software Defined Network): Separating the control plane (guiding the network

what goes where) from the data plane (sending packets to specific), making the network

more programmable.

• NFV (Network Function Virtualization): Transform tradition dedicated network appliances

to VMs and from proprietary middle boxes (appliances) to open industrial servers.
