OpenStack Neutron Plugin for ONOS

Project name: SONA(Simplified Overlay Networking Architecture)

SONA is the optimized multi-tenant network virtualization service for Cloud-based data center. Basically, it implements OpenStack Neutron's ML2 mechanism driver and L3 service plugin for ONOS, that is, it can be used to create virtual private networks and routing them through OpenStack Neutron. It leverages VXLAN based overlay networks to provision a virtual network but in an optimized way. It also provides gateway scalability, which acts as a connection point between virtual networks and outside of the world. Gateway device can be OVS or dedicated hardware.



  • Optimized logical switching : multicast free VXLAN implementation
  • Optimized logical routing : no need to go through a gateway device for East-West traffic
  • Broadcast free : ONOS provides DHCP and ARP
  • Agentless : no Neutron agents or network nodes are required
  • Scalable : provides horizontal scalability of the gateway nodes for North-South traffic
