Open Network Linux

Linux Distribution for Open Hardware Switches and Part of the OCP (Open Compute Project)

Open Network Linux (ONL) is an open source Linux distribution for bare metal switches. It provides a foundational platform software layer on which to build your own network operating systems on top of Open Networking hardware. It supports multiple switch fabric APIs and is compatible with most forwarding agents. Networking solutions based on ONL deliver speed, freedom and efficiency, and have been adopted by numerous data center organizations, from hyperscalers and service providers to mainstream enterprises and cloud providers. Open Network Linux was initially proposed by Big Switch Networks at the Open Compute Project Engineering Workshop in San Antonio in 2013 and was adopted by the OCP to be their reference network operating system.
