OpenDaylight Project

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 open, centralized, network device monitoring.

History

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 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 actually sell incumbent networking technology.[6]

Technical Steering Committee

For governance of the project, the TSC (Technical Steering Committee) serves as the advisory organ, with technical oversight over the project.[7] The TSC is able to hold voting on major changes to the project. As of November 2020,[8] the TSC consists of 5 members[9] (in order to be able to have a deciding voting number):

Code contributions

By 2015, user companies had begun participating in upstream development. The largest contributing companies include PANTHEON.tech,[10] Orange, Red Hat, Ericsson and Lumina Networks.[11] At the time of the Carbon release in May 2017, the project estimated that over 1 Billion subscribers were accessing OpenDaylight-based networks, in addition to use within large enterprises.[12]

There is a dedicated OpenDaylight Wiki,[13] and several mailing lists[14] are available. These resources are aimed at developers wishing to contribute to the project, as well as others interested in learning about specific sub-projects.

Technology

OpenDaylight Projects

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 & more.[16]

Releases

Releases follow a nomenclature, based on the chemical element's atomic number and the corresponding releases number. The following lists the different OpenDaylight releases:

Members

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 Fund,[17] which consolidated membership across multiple projects into a common governance structure. Most OpenDaylight members became members of the new LF Networking fund.
