Agenda
Why SDN matters
What OpenDaylight is and does
The open source difference
How to get involved
Networks are Evolving
Software Defined Networking (SDN) reset business opportunities
Applications and services that ride on,
optimize, exploit, and manage the
network
Focus Area
for OpenDaylight
Enterprise apps
A Software Defined Network
platform that makes the network
more programmable, agile, and
efficient
Security, load
balancing, etc. services
API’s
Software Defined Network (SDN)
Platform
Open protocols with enablement for proprietary extensions
A network that provides the
physical connectivity

Why SDN?
SDN is not a product or an endpoint. It's an
architectural approach.
By 2016, SDN will account for a remarkable
35% share of the Ethernet switching market in
the datacenter, up from almost negligible
penetration in 2012.

What Is OpenDaylight?
OpenDaylight is a community-led and industrysupported open source framework to advance
Software-Defined Networking (SDN).
OpenDaylight Project Goals

Code: To create a robust, extensible, open
source code base that covers the major
common components required to build an
SDN solution.

Acceptance: To get broad industry
acceptance amongst vendors and users.

Community: To have a thriving and growing
technical community contributing to the code
base, using the code in commercial
products, and adding value above, below
and around.

Broad Industry Support for
OpenDaylight
7
Industry Value

A broad SDN code base that anyone can use, plug into or
contribute new enhancements

A common environment for users and application
developers

Accelerated innovation by avoiding duplication of basic
infrastructure

Faster and higher quality development through sharing of
resources
8
Why Open Source?
Flexibility
Choice
Innovation
Control
Open source is more flexible and can evolve as new
technologies and innovations appear, not based on any single
vendor's purposes.
Examples: Hadoop, Linux, Apache, OpenStack

OpenDaylight Open Governance

Membership open to all

Business leadership: Board of Directors


Governance, marketing, operations
Technical leadership: Technical Steering Committee (TSC)

Technical direction, project selection, technical decisions

Meritocracy and transparency

Project life-cycle management
10
The Code

A wide array of technologies contributed by leading
companies and developers
– Pre-existing code, newly created code specifically for
OpenDaylight

Roughly bi-annual coordinated release cycles
– First release planned for December 2013

Eclipse Public License (EPL)
