SDN

The need for rapid network configuration changes

– Cloud, virtualization and mobility are driving the need for

more dynamic networks

SDN is aimed at giving IT managers

– A new tool to make networks programmable

– Automate policy-driven configuration changes

SDN enables customers to have a common,

open framework for controlling the network

– Abstract vendor driven differences from hardware

functionality

What is Software Defined Networking (SDN)?

NFV

To virtualize network functions

To be hosted on virtual machines (VMs).

The concept, which was presented by a group of network

service providers at the SDN and OpenFlow World

Congress in October 2012

Is being developed by the ETSI Industry Specification

Group (ISG) for Network Functions Virtualization.
