SONA(Simplified Overlay Network Architecture) is an optimized tenant network virtualization service for Cloud-based data center. Basically, it is a set of ONOS applications which provides OpenStack Neutron ML2 mechanism driver and L3 service plugin. The implementation for provisioning an isolated virtual tenant network uses VXLAN based L2 tunneling with Open vSwitch as a network hypervisor. It also provides horizontal scalability of a gateway node, which plays a role of connecting SONA controlled virtual networks to the outside of the world via BGP.
