Software Defined Networks
A Carrier Perspective
What is the ideal?
• Intelligent, Programmable, Open,
Application-aware
• Abstracts underlying Hardware complexity
• Disaggregates logic function into Software
• Separates Management & Control Plane
from Data Plane
• Enables applications to view, request &
manipulate NW resources

Where are we today?
• Hypervisor Virtual Switches … YES
• Disaggregated HW …
Promising/Nascent
• Overlay Protocols … Getting there
• Control / Data Plane … Google does it,
why cant we?
• Network Orchestration … OpenStack to
the rescue!
• Wide Area NW SDN…A ways off

Opens the competitive
landscape up
Innovative Ecosystem
NFV Open Platform
Drive NFV’s evolution through an open platform which the carrier and
vendor community will mutually benefit from.
•

•
•
Integrated and Tested Reference Platform
Influence and contribute changes to upstream projects
Build new components where needed
Rely on open reference implementations to drive open standards and an
open ecosystem for NFV Solutions
Initial Scope is NFVi; Virtualization, Controller, and Virtual Infrastructure
Management (VIM)
