Abstract
Software Defined Networking (SDN) and Network Function Virtualization (NFV) represent a major shift in the way networks will be designed, deployed and managed—requiring changes in infrastructure management tools and practices. This session will illustrate our vision with use cases under consideration for CA Performance Management, which is designed for managing complex, highly-scaled networks and could be applied in the future to managing Software Defined Networks and integrating with SDN controllers and NFV elements.

What Is SDN and NFV
SDN (Software Defined Networking) is an architectural change to networking focusing on three areas: Abstraction, Centralization and Automation.
Technical Review
NFV (Network Function Virtualization) is the virtualization of network services in order to reduce network equipment cost and add velocity. It is an SDN use case for CSP.

DOMAIN 2.0—AT&T’s NFV Architecture
Complexity lies in the stitching of virtual network function cloud to the physical. network
Physical environment that we know how to monitor already with our existing technology. The issue is that this physical underlay has little to do with the real activities of the new network.
A private cloud containing the network function software running as an army of virtual machines (VMs). These VMs are stitched to the physical underlay through tunnels creating a complex and dynamic interconnect.

NFV Use Case
Today’s controller is forced to provision blindly without sufficient knowledge of network capacity and availability.
The constant SDN-triggered configuration changes on VMs, network elements and servers can disrupt operational workflow.
