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.

A publisher/subscriber model dominates today's Internet usage behavior instead of a location-based host access. Along with this stream, Information-Centric Network (ICN) is proposed for Future Internet Architecture to remedy the problems the current Internet is encountered. Although there are lots of research efforts on ICN, but still evaluation and validation of their proposals stay at simulation or emulation. Thus, this requires a scalable, real physical testbed for fast prototyping.In this paper, we develop and deploy ICN-OMF: a Control, Management Framework for a scalable CCN testbed, including controlling and management of multiple CCN nodes dispersed across geographically. To this end, we leverage, extend a Testbed Control, Measurement and Management Framework (OMF) and an overlay. We believe experimenters can utilize this framework to validate and evaluate their ideas in more convenience.
