Scale-out Multi-vendor VNFs can
run on the same platform
Interoperates with different
Orchestration systems
Integrates with
different Linux Hosts,
multiple hypervisors, and
multi-vendor X86 servers
Multi-vendor SDN Gateway (any
router that can talk BGP and the
aforementioned tunneling protocols)
Data Plane: Overlay Tunnels
(MPLSoGRE, MPLSoUDP, VXLAN)
Control Plane: BGP Control Plane
(logically centralized, physically
distributed Controller elements)
Automation: REST APIs to integrate
with different Orchestration Systems
