Abstract
This disclosure describes techniques for improved multicast network telemetry implemented over multilayer switches in a PIM domain. The multilayer switches may be configured to collectively certify end-to-end flow provisioning, and to publish telemetry data certifying flow provisioning from a single notifier to an external controller host. Computational workload and network traffic for streaming data related to certifying path provisioning is kept to a minimum for each flow that needs to be certified, which also keeps compounding of network traffic for many different flows to a minimum. Moreover, since controller hosts are notified upon successful provisioning but not at other times, controller hosts can trust that the telemetric data is minimally latent, and may be relied upon to enact timely actions which produce desired outcomes.
