Transformation in Networking Infrastructure•Industries are expected to adopt a software based network approach

• Transformations are happening in business infrastructure accordingly

• SDN and NFV familiar are familiar to industry stalwarts

• Software-centric future is on the cards

What is SDN?• Software Designed Networking or SDN is a

paradigm the physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.

• It is a software based approach which can act in a similar manner as a network hardware.

NFV – Network Functions Virtualization

• Virtualization is a great approach for most businesses.

• Capital Expenditure (CAPEX) and Operating Expenditure (OPEX) is cut down significantly.

• Telecom is the focus of NFV as this is a majorly impacted segment today.

Which parts of the network can be virtualized?Switching

Network appliances

Applications

Network services

SDN and NFV: Complementing each other

• NFV, along with reducing CAPEX and OPEX, helps in managing network complexity and improving scalability.

• SDN is instrumental in separating the layers of control and forwarding in a network, thereby increasing flexibility.

In a Nutshell• Cloud NFV is an initiative that brings

together cloud-based deployments using an OpenStack model into the NFV concept.

• The strong relationship between the implementation of these concepts can also be seen by this collaboration to accelerate the development of NFV with SDN support.
