Summary: 
This paper proposes a name-based routing mechanism called Routing Guidance Name (RGN) that offers new routing management functionalities within the basic characteristics of CCN. The proposed mechanism names each CCN router. Each router becomes a Data Provider for its name. When a CCN Interest specifies a router's name, it is forwarded to the target router according to the standard mechanism of CCN. Upon receiving an Interest, each router reacts to it according to RGN. This paper introduces a new type of node called a Scheduler which calculates the best routes based on link state information collected from routers. The scheduler performs its functions based on RGN. This paper discusses how the proposed system builds CCN FIB (Forwarding Information Base) in routers. The results of experiments reveal that RGN is more efficient than the standard CCN scheme. It is also shown that the proposal provides mobility support with short delay time. We explain a practical mobile scenario to illustrate the advantages of the proposal.
