…..who rides into town??
those with Big Networks,and Huge Data Centers
Google, Verizon, Microsoft, Yahoo!, Deutsche Telekom,
…
Open Networking Foundation (ONF)“Revolutionizing the Networking Industry”
… prying open the networking devices.
Software Defined Networking (SDN)
Decouple the Control and Data Planes
Eliminate Control Plan from Network Devices

Decouple the Control and Data Planes
Eliminate Control Plan from Network Devices
use separate general purpose machine (“Controller”) to Program and Query the Data Planes of the cheap commodity switches
