The Open Networking Foundation on Tuesday introduced an update to its Atrium open source SDN stack, with added support for OpenDaylight and leaf-spine architecture.
Atrium, released last year, is designed as a platform to give network operators a taste of open source SDN -- "a vertical slice of something useful," Dan Pitt, Open Networking Foundation executive director, tells Light Reading. Open source and SDN are fundamental to New IP networks. (See ONF Updates Atrium Open SDN Software.)
Atrium isn't abandoning ONOS -- it also supports that controller, with improved scalability and stability and by adding experimental support for the Interior Gateway Protocol (IGP).
Support for a leaf-spine architecture means an individual controller can control many switches. In the first version of Atrium, a single controller controlled only an individual switch.
Atrium provides network operators with a functional router, for laboratory use, to help them shop for a product.
