RAON: A recursive abstraction of SDN control-plane for large-scale production networks
In this invited paper, we introduce RAON: a recursive abstraction of SDN control-plane for large-scale production networks. RAON leverages a recursion, where the solution to a problem depends on solutions to smaller instances of the same problem, and organizes them in hierarchical domains.
To this end, RAON abstracts the details of the underlying network as a big virtual switch, then the switch is recursively connected to other controllers like normal openflow switch. We have implemented and deployed RAON in our lab-scale testbed.
