SONA: Data Center Network Virtualization Simplified Overlay Network Architecture 8 Ref: https://wiki.onosproject.org/display/ONOS/SONA:+DC+Network+Virtualization 

SONA Objective • Optimized tenant network virtualization service for DC • Based on ONOS which provides § OpenStack Neutron ML2 driver § L3 service plugin • Provisioning an isolated virtual tenant network § Use VXLAN based L2 tunneling with Open vSwitch as a network hypervisor § Use BGP provides horizontal scalability of gateway node 9
