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 ArchitectureComplexity 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.
