…yet the underlying network that connects everything has
remained unchanged!

4. The Network is Being Pushed to Its Limits…
Unending, exponential growth in the people, devices and servers connecting to
the network requires a new approach.

SDN Definition
1. Separates the network’s control (brains)
and forwarding (muscle) planes
2. Provides a centralized view of the overall
network
3. Utilizes programmatic application
interfaces (APIs)
4. Enables efficient orchestration and
automation of network services

8. SDN Promises
Agility: enabling organizations to rapidly deploy
applications, services, and infrastructure to meet needs
Scale: automate and optimize new and existing
applications and services
Innovation: allowing organizations to create and deliver
new types of applications, services and business models
SDN Opens the Network Up for Innovation

It replaces static, inflexible and complex networks, with networks that
are agile, scalable and innovative.

10. The Concepts Behind SDN are Not Particularly New
The Separation of the Control Plane has been around for a while…..
We saw separated
control & data planes in
separate boxes in the
early ‘90’s
…which evolved to a distributed
control plane within switches in
the mid -90’s
… and then a distributed control
plane in Wireless access points
(Aps) by the early ‘00’s
…until we saw separated
control and data planes for
particular use cases in the
late ‘00’s

11. There is Past Experience to Draw On
• Focused on centralized management & wireless
control-plane
• Lack of northbound APIs
• Telco Equipment (MPLS, etc.)
• Control-plane/Data-plane was separate
• Solutions were closed, using proprietary
communications channels

Controller-Based Wireless Routers
The problem with past solutions is that they only offered narrow
applications of the concepts
…and were not truly open for innovation
