PROBLEM TO BE SOLVED: To provide a route-tracing application measuring the performance of a path in a named-data network.SOLUTION: A network node performs a lookup operation in a forwarding information base (FIB) using an interest's name, and each FIB entry maps the name to a forwarding rule. If the FIB does not include an entry for the interest's route-tracing name, a trace agent determines one or more outbound interfaces for the route-tracing operation on the basis of the interest's name, creates new route-tracing FIB entries, and each route-tracing FIB entry maps the interest's name to a forwarding rule for the determined interfaces. The network node returns a content object that satisfies the interest, in which the content object includes the names of the new FIB entries, as well as performance information for the path. |
