MENLO PARK, Calif. -- ON.Lab today announced that ONOS, the open source SDN Network Operating System for service providers and mission critical networks, has achieved two significant milestones in a short period of two months after its successful launch. Following its open source release on Dec. 5, 2014, ONOS has now crossed 1,000 software downloads globally and announced the expansion of its partnership with the addition of new members – Cisco and SK Telecom. Networking vendor Cisco and SK Telecom, Korea's largest telecommunications company, will join the ONOS community comprised of leading service providers, vendors, collaborators and individual contributors to accelerate SDN adoption and drive open innovation.

ONOS is a carrier-grade SDN network operating system for service provider networks architected to provide high availability, scalability, performance, and rich northbound and southbound abstractions. Cisco and SK Telecom join founding members who are funding and contributing to the ONOS initiative including: AT&T, NTT Communications, Ciena, Fujitsu, Huawei, Intel, NEC; as well as members who are collaborating and contributing to ONOS including ONF, Infoblox, SRI, Black Duck, Internet2, GARR, CNIT and Create-Net.

ONOS was open-sourced and made publicly available for download on Dec. 5, 2014, by ON.Lab, service providers, vendors and collaborators. In addition to the number of downloads, ON.Lab saw impressive attendance at its pre- and post-launch events including a total of more than 1000 attendees at its two ONOS webinars and 100+ business leaders from leading service providers and vendors at its partner summit in Palo Alto, Calif.

ONOS has been well received by the developer community as is evident from the fast adoption of the open source release, as well as rapid growth in the community contributions to the ONOS codebase and feature set following this release.

ONOS is an SDN network operating system for service provider networks and mission critical networks. This platform delivers a highly available, scalable SDN control plane featuring northbound and southbound open APIs and paradigms for a diversity of management, control, and service applications. Initially targeted to service providers, ONOS will expand into cloud service providers, enterprises and into mainstream deployments. The addition of new partners, code, and use cases will be a strong driver for the growth of its ecosystem and its continued successful evolution.
