Difference between SDN and NFV:
Below table summarizes the difference between the two:
|Strategy||Separation of control and Data , centralization of control and programmability of network||Replacement of dedicated appliances and devices with generic servers.|
|Benefits||1.Simplification of –
·Configuration of entire network
·Operation of network since consolidation
2.Reduced cost due to no longer dependency on expensive vendor specific routers and switches.
|1.Speed up time to market
2.Simplification of procurement, design, integration and management of infrastructure since this all is standardized.
3.Increased scalability by dynamically allocating resources to network functions.
