ONOS vs Open Virtual Network
Both stand on data center fabric software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxMac+2
Choose ONOS for a software-defined network control plane with distributed operation and a broad set of device interfaces. It is aimed chiefly at service-provider networks, though the architecture also identifies data center and campus uses.
