(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
  • Logical switching for East-West traffics : No need to go through gateway device for East-West traffictraffics
• Broadcast free : use built in ONOS applications for DHCP and ARP
• Agentless : no Neutron agents or network nodes are required
• Scalable gateway
