CCNinfo: Discovering Content and Network Information in Content-Centric Networks

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, 2) the Round-Trip Time (RTT) between the content forwarder and consumer, and 3) the states of in- network cache per name prefix.
