Want to Understand the Hype Around Software Defined Networking (SDN)? This Presentation Defines What SDN Is, Why It's Important and What You Should Know to Start to Take Advantage of It...
4. The Network is Being Pushed to Its LimitsâŠ
Unending, exponential growth in the people, devices and servers connecting to
the network requires a new approach.

SDN Definition
1. Separates the networkâs 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 whileâŠ..
We saw separated
control & data planes in
separate boxes in the
early â90âs
âŠwhich evolved to a distributed
control plane within switches in
the mid -90âs
⊠and then a distributed control
plane in Wireless access points
(Aps) by the early â00âs
âŠuntil we saw separated
control and data planes for
particular use cases in the
late â00âs

MPLS & 3GPP VendorsâŠ
11. There is Past Experience to Draw On
âą Focused on centralized management & wireless
control-plane
âą Lack of northbound APIs
âą Telco Equipment (MPLS, etc.)
âą Control-plane/Data-plane was separate
âą 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
âŠand were not truly open for innovation
