Contrace: Traceroute Facility for Content-Centric Network
This document describes the traceroute facility for Content-Centric Network (CCN), named "Contrace". Contrace investigates: 1) the 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 NDN.
