SDN and NFV are two distinct technologies that have been developed to help organizations improve their network operations. They both offer different benefits and can be used together or separately. This article will explore the differences between these two technologies, outlining their key features and how they can be used in an organization's network infrastructure.
About Difference Between Sdn And Nfv
| Concept | Difference |
|---|---|
| SDN (Software Defined Networking) | A network architecture that separates the control plane and data plane, allowing for dynamic, programmable network configurations. |
| NFV (Network Function Virtualization) | An approach to virtualizing network services by moving them from dedicated hardware appliances to software running on general purpose servers. |
| Architecture | SDN uses a centralized controller to manage traffic flow while NFV relies on distributed computing resources. |
| Deployment | SDN is typically deployed in an overlay fashion while NFV can be deployed as an overlay or natively within the existing infrastructure. |
| Scalability | SDN provides greater scalability than NFV. |
| Costs | NFV is more cost-effective than SDN due to its use of commodity hardware. |
| Flexibility | NFV offers greater flexibility than SDN, allowing for easier deployment and management of services. |
