DifferenJaJng SDN & NFV COMPLIMENTARY, BUT INDEPENDENT TECHNOLOGIES
Software
Custom Hardware
Purpose-built dedicated
device
Consolidate diverse network equipment types (firewall, switching, routing, ADC, BRAS, EPC, etc. ) onto industry-standard x86 servers using virtualization. Benefits: Reduced cost and increased agility
NFV SDN
Software Software Hypervisor
x86 Hardware
Industry-standard server
Separate control plane from the data plane in network devices (physical and virtual) with intelligence and programmability centralized in a controller. Benefits: Increased agility via automa:on and increased innova:on via programmability
