ONOS is building a better network.

ONOS is the only SDN controller platform that supports the transition from legacy “brown field” networks to SDN “green field” networks. This enables exciting new capabilities, and disruptive deployment and operational cost points for network operators.

ONOS is the only open source controller providing:


Offers virtually unlimited replication for scaling control plane capacity is needed

High Performance

Performs to the exacting specifications of large network operators


Provides the availability required for mission critical operator networks.

Legacy device support

Makes it easy to add or configure traditional devices and services with model based dynamic configuration

Next-Generation device support

Gives real-time control for native SDN dataplane devices with OpenFlow® and now with P4 support

Enabling next-generation solutions in service provider networks

ONOS has enabled the SDN revolution. Combining ONOS with white box switches and ONOS applications enables new forms of innovation never before possible with closed legacy networks.


CORD™ (Central Office Re-architected as a Datacenter) is delivering edge cloud for operators, reinventing the edge of operator networks in cloud-native ways for efficiency and agility. By blending the best of Cloud, SDN and NFV, CORD provides complete integrated solutions for fixed access (PON), mobile and wireless 5G access, mobile core (EPC) and enterprise service delivery.


ODTN (Open Disaggregated Transport Network) is disaggregating carrier core networks, and reassembling a solution using SDN principles and white box efficiencies to build high performance backbones with disruptive economics.


Trellis is a complete spine leaf datacenter fabric solution with multi-tenant overlay support, built completely with bare metal white box switches.

And More

Various SDN solutions for switches, PON (OLTs), Wireless (RANs & eNBs), and ROADMs
