SDN OS from ON.Lab is Now Available for Download

By Paula Bernier December 08, 2014

Those who were anxiously awaiting the availability of the Open Network Operating System got their wish Friday night when an industry group called the Open Networking Lab made the software available for download. As reported by NFVZone last month, the Dec. 5 release date was expected.

ONOS is an SDN OS designed for use in service provider networks. Based on a distributed core, it runs on multiple servers. That allows for high availability, performance, and scalability; specifically, ONOS promises 100-millisecond recovery and the ability to process 1 million requests per second. The group says ONOS also has rich northbound and southbound abstractions.

Among the ONOS use cases are SDN control of multilayer networks, which means service providers no longer have to operate separate packet and optical networks, and need to do less overprovisioning; SDN network peering; and SDN-based WAN control with segment routing, in which MPLS is used as the data plane, and SDN is used for SDN control, in an effort to simplify the network.

The Open Networking Lab, or ON.Lab for short, is a group of companies including service providers AT&T and NTT Communications, and vendors Ciena, Fujitsu, Huawei, Intel, and NEC, among others.

AT&T and NTT have been pioneers in not only exploring but also introducing SDN-based services.

AT&T since June has been pilot testing its Network On Demand SDN, which allows companies to provision and adjust their own network services, in Austin. The service is expects to go commercial in Austin by the end of this year, and should launch in additional U.S. markets in 2015.

And NTT in May announced that its Arcstar Universal One service, also a customer self-provisioning offer leveraging NFV and SDN technologies, is available in more than 190 countries.
