US 11,902,136 B1 · Adaptive flow monitoring

Abstract

An example network device includes memory, a communication unit, and processing circuitry coupled to the memory and the communication unit. The processing circuitry is configured to receive first samples of flows from an interface of another network device sampled at a first sampling rate and determine a first parameter based on the first samples. The processing circuitry is configured to receive second samples of flows from the interface sampled at a second sampling rate, wherein the second sampling rate is different than the first sampling rate and determine a second parameter based on the second samples. The processing circuitry is configured to determine a third sampling rate based on the first parameter and the second parameter, control the communication unit to transmit a signal indicative of the third sampling rate to the another network device; and receive third samples of flows from the interface sampled at the third sampling rate.
