Abstract: Apparatus, method and non-transitory computer readable medium for traffic policing detection and rate limit estimation for a network, including selecting from the network sampled packets having a loss rate greater than a first threshold, the selected sampled packets being added to a sliding window for traffic policing detection; in response to the number of sampled packets in the sliding window reaching a predetermined number, determining a correlation coefficient based on a sending rate and the loss rate of at least one sampled packet in the sliding window; in response to the correlation coefficient exceeding a second threshold, determining whether traffic policing is occurring in the network based on the sending rate and a transformed loss rate of the at least one sampled packet; and in response to traffic policing occurring, determining an estimated rate limit for traffic policing based on an acknowledgement rate of the at least one sampled packet.
