Software Defined Networking (SDN)In One MinuteA non-technical executive guide
Software Defined Networking in 1 minute
How traditional networking… works
Imagine you have a packet that needs delivering
You give it to a courier - It’s now in the network
The courier asks directions at different points
If it’s busy he asks for a different route
If the packet is too big, he takes a less crowded route
The people he asks are like routers – they have the knowledge

How SDN works
The courier now has a smartphone with GPS
The route is constantly updated and controlled centrally
The control knows the size of the packet and routes it accordingly
It can overlay information such as traffic conditions…
…that dynamically update his route… all from the central point
If his phone packs up, he can still ask the way

Getting technical
The central point, or “Control Plane”, is software
Traditionally this is contained on routers along with a “Data Plane”
SDN decouples the “control plane” from the “data plane”
A network administrator no longer needs to hope all the routers are optimally configured along the route for his packet
Benefits?
Faster networking for big packets like video
Cheaper simpler hardware
Reduced reliance on hardware configuration
Reduced dependence on vendors’ equipment product cycles
