Abstract: A computational method and system for estimating port delays in a network may use a data-driven estimation with quadratic programming based on available network path data that is already collected. In this manner, port delays for each individual port in the network may be estimated without having to measure each individual port using sensors.

Abstract: A method may include determining a first number of events occurring during a first threshold detection duration. The method may further include causing processing of events to cease for a particular throttling duration in response to determining that the first number of events occurring during the threshold detection duration is greater than a predetermined threshold. The method may also include determining a second number of events occurring during a second threshold detection duration. Additionally, the method may include, in response to determining that the first number of events occurring during the first threshold detection duration is greater than the predetermined threshold and that the second number of events occurring during the second threshold detection duration is greater than the predetermined threshold: increasing the time of the particular throttling duration; and causing processing of events to cease for the increased particular throttling duration.
