METHOD AND APPARATUS FOR DIAGNOSING FAULTS IN A HYBRID INTERNET PROTOCOL NETWORK

摘要

An Ethernet switch can receive an internet protocol query packet generated by a receiver for collecting telemetry data between a source and the receiver in a multicast network, translate the internet protocol query packet to an Ethernet query packet, collect in the Ethernet query packet telemetry data from the Ethernet switch where at least one telemetry field of the Ethernet Switch includes an arrival time of the Ethernet query packet at the Ethernet switch, and submit the Ethernet query packet to the next network element of the multicast network. An internet protocol router can receive an Ethernet query packet generated by an Ethernet switch having at least one field for telemetry for collecting telemetry data between a source and a receiver, translate the Ethernet query packet to an internet protocol query packet, and submit the internet protocol query packet to the next network element. Additional embodiments are disclosed.
