Abstract
A test device enables DOCSIS link testing in a HFC network without requiring the CMTS or other router at the headend of the HFC network to respond to ICMP messages. The test device includes a test packet generator for generating test packets having a destination Internet protocol (IP) address associated with a test device, a memory for storing transmission parameters of the test packets, and a test packet evaluator associated with the IP address in the generated test packets. The test packet evaluator receives the generated test packets after the test packets have been routed through a router at a head end of a HFC network and compares reception parameters for the received test packets to the transmission parameters stored in the memory.
