| 1. A test device for evaluating data communication paths over a hybrid fiber cable (HFC) network comprising:
a test packet generator for generating test packets;
a memory for storing transmission parameters of the test packets; and
a test packet evaluator for receiving the generated test packets after the test packets have been routed through a router
at a head end of a HFC network and for comparing reception parameters for the received test packets to the transmission parameters
stored in the memory;
wherein the test packet generator is capable of generating the test packets with a source Internet protocol (IP) address associated
with the test packet generator and a destination Internet protocol (IP) address associated with the test packet evaluator,
whereby the test packets get relayed to a head end of the HFC network and routed back to the test packet evaluator.
