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

Internet / WAN or Legacy Env.
