The OpenDaylight Project is a collaborative open-source project hosted by the Linux Foundation. The project serves as a platform for software-defined networking (SDN) for customizing, automating and monitoring computer networks of any size and scale.
On April 8, 2013, The Linux Foundation announced the founding of the OpenDaylight Project. The goal was to create a community-led and industry-supported, open-source platform to accelerate adoption & innovation in terms of software-defined networking (SDN) and network functions virtualization (NFV). [1] [2] The project's founding members were Big Switch Networks, Brocade, Cisco, Citrix, Ericsson, IBM, Juniper Networks, Microsoft, NEC, Red Hat and VMware. [3]
Reaction to the goals of open architecture and administration by The Linux Foundation have been mostly positive. [4] [5] While initial criticism centered on concerns that this group could be used by incumbent technology vendors to stifle innovation, most of the companies signed up as members do not sell incumbent networking technology. [6]
For governance of the project, the technical steering committee (TSC) provides technical oversight over the project. [7] The TSC is able to hold voting on major changes to the project. As of June 2022, [8] the TSC includes:
| Term Years | TSC Chair |
|---|---|
| 2013, 2014 | David Meyer |
| 2015, 2016, 2017 | Colin Dixon |
| 2018, 2019, 2020 | Abhijit Kumbhare |
| 2021, 2022 | Guillaume Lambert |
By 2015, user companies began participating in upstream development. The largest, actively contributing companies include PANTHEON.tech, [10] Orange, Red Hat, and Ericsson. [11] At the time of the Carbon release in May 2017, the project estimated that over 1 billion subscribers accessing OpenDaylight-based networks, in addition to its usage within large enterprises. [12]
There is a dedicated OpenDaylight Wiki, [13] and mailing lists. [14]
The platform is described as a modular, open-source platform for automating networks. Part of the concept of modularity are over 50 projects, which address & extend the capabilities of networks managed by OpenDaylight. Each project has a formal structure, teams and meetings to discuss releases, functionality and code. [15] Projects include BGPCEP, TransportPCE, NETCONF, YANG Tools, and others. [16]

Originally there were three tiers of membership for OpenDaylight: Platinum, Gold and Silver, with varying levels of commitment.
As of January 2018, OpenDaylight became a project within the LF Networking Foundation, [17] which consolidated membership across multiple projects into a common governance structure. Most OpenDaylight members became members of the new LF Networking Foundation.
Free and open-source software (FOSS) is a term used to refer to groups of software consisting of both free software and open-source software where anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users.
Vyatta is a software-based virtual router, virtual firewall and VPN product for Internet Protocol networks. A free download of Vyatta has been available since March 2006. The system is a specialized Debian-based Linux distribution with networking applications such as Quagga, OpenVPN, and many others. A standardized management console, similar to Juniper JUNOS or Cisco IOS, in addition to a web-based GUI and traditional Linux system commands, provides configuration of the system and applications. In recent versions of Vyatta, web-based management interface is supplied only in the subscription edition. However, all functionality is available through KVM, serial console or SSH/telnet protocols. The software runs on standard x86-64 servers.
The Linux Foundation (LF) is a non-profit organization established in 2000 to support Linux development and open-source software projects. In addition to providing a neutral home where Linux kernel development can be protected and accelerated, the LF is dedicated to building sustainable ecosystems around open-source projects to accelerate technology development and commercial adoption.
The Free Software Foundation (FSF) is a 501(c)(3) non-profit organization founded by Richard Stallman on October 4, 1985, to support the free software movement, with the organization's preference for software being distributed under copyleft terms, such as with its own GNU General Public License. The FSF was incorporated in Boston, Massachusetts, US, where it is also based.
Simon Phipps is a computer scientist and web and open source advocate.
OpenStack is a free, open standard cloud computing platform. It is mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users manage it either through a web-based dashboard, through command-line tools, or through RESTful web services.
FreedomBox is a free software home server operating system based on Debian, backed by the FreedomBox Foundation.
Cloud Foundry is an open source, multi-cloud application platform as a service (PaaS) governed by the Cloud Foundry Foundation, a 501(c)(6) organization.

The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation. It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space. This offloading achieves higher computing efficiency and higher packet throughput than is possible using the interrupt-driven processing provided in the kernel.
OpenConnect is a free and open-source cross-platform multi-protocol virtual private network (VPN) client software which implement secure point-to-point connections.
