Abstract: A mechanism for adaptively performing in-band network telemetry (INT) by a network controller is disclosed. The mechanism includes receiving one or more congestion indicators from a collector. An adjusted sampling rate is generated. The adjusted sampling rate is a specified rate of insertion of instruction headers for INT and is generated based on the congestion indicators. The adjusted sampling rate is transmitted to a head node, which is configured to perform INT via instruction header insertion into user packets.

Abstract: A method for delivering operations, administration and maintenance (OAM) configuration information includes obtaining, by a control node in a communication network and from at least two of a plurality of first nodes in the communication network, advertisement packets, wherein each of the advertisement packets comprises indication information indicating a corresponding path detection mode supported by a sender of each of the advertisement packets; determining, by the control node based on a path detection mode to be used and the advertisement packets, a detection path; and delivering OAM configuration information to a head node in the detection path and a tail node in the detection path.
