Zusammenfassung:A system and methods for reliable telemetry are disclosed herein. In an example of reliable in-band telemetry in a communications network, intent information for a destination device may be generated at a network device indicating a type of telemetry data to be collected. The network device may update a locally stored invertible Bloom function (IBF) by applying one or more hash function to the intent information, a destination identifier (ID) associated with the destination device, and/or a local timestamp, and periodically forward the locally stored IBF to the destination device. The network device may receive a notification message by the destination device that the intent information is missing at the destination device and re-forward the intent information to the destination device. In another example, a network device may maintain and periodically forward a locally stored IBF based on response data and the destination ID.
