There is a Need to Innovate in the Network
We’ve seen tons of innovation in applications, devices, computing and storage,

Revenues from Cloud Innovation Could Reach $1.1 Trillion Per Year by
2015 IDC

…yet the underlying network that connects everything has remained unchanged!
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 Definition1. 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

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

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
MPLS & 3GPP Vendors…

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
Data Center Chassis-Based Switches & Routers
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
