9. 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

16. Trellis Summary
    • Underlay Fabric
    § L2/L3 spine-leaf fabric – Bare-metal hardware + open source software
    § SDN control plane – No distributed protocols
    § Modern ASIC data plane – 1.28 Tbps switching bandwidth for each switch
    • Virtual Network Overlay
    § Designed for NFV – ChainedVNFs using with best principles of cloud
    § Overlay Control – XOS and VTN implement service graph
    § OVS + VXLAN Data Plane
    • Unified SDN Control
    § Common Control – Opportunity for optimized service delivery
