Abstract
Methods are provided to categorize and filter node metadata by adding a priority field to the node metadata, obtained as part of in-band network telemetry data collection. The methods involve obtaining, by a first network device, a packet having a header and a payload and adding, by the first network device, to the header of the packet, metadata which includes first telemetry data and a metadata priority level that indicates a priority of the first telemetry data added to the header of the packet by the first network device. The methods further involve providing the packet to a second network device in a path of a network.
