Introduction to SDN OpenDayLight Project

What is SDN OpenDayLight Project?

The OpenDayLight Project is a collaborative open source project in a vendor-neutral environment. The goal of the project is to accelerate the adoption of software-defined networking (SDN) and create a solid foundation for Network Functions Virtualization (NFV). The software is written in Java.

OpenDayLight, the largest open source SDN controller, is helping lead the transition for building programmable networks that are flexible and responsive to organizations’ and users’ needs.


OpenDayLight Project is hosted by The Linux Foundation. It all started on April 8, 2013 when Linux Foundation announced the founding of the OpenDayLight Project as a community-led and industry-supported open source framework to accelerate adoption, foster new innovation and create a more open and transparent approach to Software-Defined Networking (SDN) and Network Functions Virtualization (NFV).The founding members of project were committed to donating software and resources for OpenDayLight’s open source framework, a platform for SDN. The member were –

  • Arista Networks
  • Big Switch Networks
  • Brocade
  • Cisco
  • Citrix
  • Ericsson
  • HP
  • IBM
  • Juniper Networks
  • Microsoft
  • NEC
  • Nuage Networks
  • PLUMgrid
  • Red Hat and
  • VMware

A lot of deliberations have been happening on OpenDayLight project and members working day and night to improve the framework capabilities and adjusting experience. Below are the OpenDayLight releases –




OpenDayLight Project SDN


As shown is the above Project framework of OpenDayLight , the open community is building following key elements:

  • An evolvable SDN platform capable of handling diverse use cases and implementation approaches
  • Common abstractions of capabilities Northbound for people to program
  • Intermediation of those capabilities to multiple Southbound implementations
  • Programmable network services
  • Network applications
  • Whatever else we need to make it work
