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.
