Open Daylight

open-daylight-logoOpenDaylight is a community-led, open, industry-supported framework, for accelerating adoption, fostering new innovation, reducing risk and creating a more transparent approach to Software-Defined Networking.

As a collaborative project under The Linux Foundation, OpenDaylight is structured using open source development best practices, and is comprised of the leading organizations in the technology industry.

Why OpenDaylight?

The adoption of new technologies and pursuit of programmable networks has the potential to significantly improve levels of functionality, flexibility and adaptability of mainstream datacenter architectures. To leverage this abstraction to its fullest requires the network to adapt and evolve to a Software-Defined architecture. One of the architectural elements required to achieve this goal is a Software-Defined-Networking (SDN) platform that enables network control and programmability.

Today, SDN is a hotbed of innovation with a broad spectrum of vendors bringing products and technologies to market. Ironically, the myriad options may prove counterproductive to SDN adoption. Many organizations, overwhelmed by choice, also have to avoid the pitfalls of nascent technologies such as inconsistent interoperability, limited management tools or fragmentation.

At this early stage of SDN adoption, the industry acknowledges the benefits of establishing an open, reference framework for programmability and control through an open source SDN solution. Such a framework maintains the flexibility and choice to allow organizations to deploy SDN as they please, yet still mitigates many of the risks of adopting early stage technologies and integrating with existing infrastructure investments.

With OpenDaylight, a community has come together to fill this need through the combination of open community developers and open source code and project governance that guarantees an open, community decision making process on business and technical issues. Establishing an open source project in this way is designed to help accelerate the development of technology available to users and enable widespread adoption of Software-Defined Networking.

OpenDaylight can be a core component within any SDN architecture. Building upon an open source SDN controller enables users to reduce operational complexity, extend the life of their existing infrastructure hardware and enable new services and capabilities only available with SDN. Whether your organization is an enterprise IT provider, a network service provider or a Cloud services provider, you can begin taking advantage of SDN using a community-driven, open source controller framework available today.


Citrix supports the open source community via developer support and evangelism. We have a number of developers and evangelists that participate actively in the open source community in Apache Cloudstack, OpenStack, OpenDaylight, Xen Project and XenServer. We also conduct educational activities via the Build A Cloud events held all over the world.
