This document describes a mechanism named "CCNinfo" that discovers information about the network topology and in-network cache in Content-Centric Networks (CCN). CCNinfo investigates: 1) the CCN routing path information per name prefix, device name, and function/ application, 2) the Round-Trip Time (RTT) between content forwarder and consumer, and 3) the states of in-network cache per name prefix. In addition, it discovers a gateway that supports different protocols such as CCN and Named-Data Networks (NDN).
