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
