Abstract
A route-tracing application can measure the performance of a path in a named-data network using trace agents deployed across various network nodes. During operation, a network node can process a route-tracing Interest by performing a lookup operation in a forwarding information base (FIB) using the Interest's name, in which a respective FIB entry may map the name to a forwarding rule. If the FIB does not include an entry for the Interest's route-tracing name, a trace agent at the network node determines one or more outbound interfaces for the route-tracing operation based on the Interest's name, and creates new route-tracing FIB entries that each 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.
