Remote probing for remote quality of service monitoring

摘要

In one embodiment, a targeted node in a computer network receives a probe generation request (PGR), and in response, generates a link-local multicast PGR (PGR-Local) carrying instructions for generating probes based on the PGR. The targeted node then transmits the PGR-Local to neighbors of the targeted node to cause 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. In another embodiment, a particular node in a computer network receives a link-local multicast probe generation request (PGR-Local) from a targeted node in the computer network, the targeted node having received the PGR-Local from a remote device, and determines how to generate probes based on instructions carried within the PGR-Local before sending one or more probes to a collection device in the computer network according to the PGR-Local instructions.
