The Open Networking Foundation (ONF), last week released Atrium, an open SDN software distribution that includes components from other open-source efforts. Atrium is designed to help the networking industry as a whole more easily adopt open SDN by integrating established open source SDN software with some critical connecting pieces.

The first release, Atrium 2015/A, incorporates the Border Gateway Protocol (BGP), the Open Network Operating System (ONOS), and Open Compute Project (OCP) components. The software elements run in either controllers or switches, communicating via the OpenFlow™ protocol, and include plugin opportunities for other switching solutions to help foster an open ecosystem of interoperable, hardware-based OpenFlow switches.

According to ONF, routing is often the most basic application operators want for SDN, and Atrium 2015/A includes Quagga BGP because it is a popular open source routing stack. Atrium 2015/A is built on ONOS because Quagga runs on ONOS, with which ONOS has prior experience, and ON.Lab contributed engineering resources to help with the internal “flow objectives” interface and other integration efforts. 

Dan Pitt, executive director of the Open Networking Foundation
Atrium is the first top-to-bottom, soup-to-nuts open source implementation that someone can actually download from GitHub and use to run a real network. Atrium’s philosophy is to build on software from many developers that has been community developed and tested to help network operators more easily build custom solutions and allow vendors to take advantage of common building blocks, reducing their development costs and improving interoperability.

Yatish Kumar, Atrium project lead, member of the ONF Technical Council, director of the ONF Specifications Area, and CTO of Corsa Technology
Atrium is entirely focused on ease of open SDN deployment by lowering barriers to adoption. We continue to view OpenFlow as key to meeting operator needs for a functional multi-vendor southbound protocol. We will build on Atrium’s offerings not only in the controller and switch spaces but also in the application space, making sure that the OpenSourceSDN.org community has a voice in what is included in future releases.
