Claim Text:
1. A method, comprising: receiving, at a targeted node in a computer network, a probe generation request (PGRL wherein the targeted node provides remote probing for remote quality of service monitoring of one or more adjacent neighbors; in response, generating a link-local multicast PGR (PGR-Local) carrying instructions for generating probes based on the PGR; transmitting the PGR-Local to the one or more neighbors of the targeted node to cause the one or more of the neighbors to generate and transmit probes to a collection device in the computer network according to the PGR-Local instructions; receiving acknowledgments from the one or more neighbors for the PGR-Local; and in response to an insufficient number of acknowledgments, transmitting the PGR-Local to the neighbors with an incremented time-to-live (TTL).
