Seamless Interworking of SDN and IP
SDN-IP helps migrate your network to SDN • Allows an SDN network to seamlessly connect to rest of the Internet using BGP• Peers with BGP speakers and creates OpenFlow paths in the network in response to
received routes from the peers • Allows scaling of SDN control plane by interconnecting smaller SDN networks
Architecture of SDN-IP Network PeeringScaling SDN Control
Real Deployment• Internet2 AL2S network• Connecting 6 universities around US• 40 OpenFlow switches• No routers in the core• Require high availability for the control
