class Scriptroute::ProbeResponse
A ProbeResponse
is a pair of a probe and its response. Scriptroute
is designed around the idea that a general purpose engine can recognize the response to any probe, and be in charge of doing so, so that measurement tools need not have the rights to look at every packet.
This design does limit somewhat, since probes that are capable of soliciting more than one response (e.g., via fragmentation) will not be managed properly.
