5. Software Defined Networks
A Carrier Perspective
What is the ideal?
Where are we today?
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
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

9. Classic Network Appliance Approach
Physical Network Function (PNF)
Limitations
Fragmented non-commodity HW
Message
Router
CDN
Session Border
Controller
WAN
Acceleration
Physical install per appliance per site
Low asset utilization
HW development is time consuming and can’t be continuously deployed / upgraded
