SDN vs NFV
Difference between SDN and NFV:
Below table summarizes the difference between the two:
Category | SDN | NFV |
Strategy | Separation of control and Data , centralization of control and programmability of network | Replacement of dedicated appliances and devices with generic servers. |
Protocol | OpenFlow | Not presently |
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. |
Supporters to initiative | Enterprise Software and Hardware Vendors | Telecom Service Providers |
Formalization | Open Networking Forum (ONF) | ETSI NFV Working Group |
Target Scope | Cloud, Data Center and Campus environment | Service Provider domain |
Applicability | Works on Layer 2 and 3 of OSI Model | Works on Layer 4-7 of OSI Model |
Application run | Industry standard servers / switches | Industry standard Servers |
