Method and system for interrupt throttling and prevention of frequent toggling of protection groups in a communication network

摘要

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.

1. A method comprising:
determining, by a network element, a first plurality of events occurring during a predetermined first threshold detection duration, wherein the events comprise protection switches between a working path and a protection path coupled to the network element or interrupts associated with protection switches between the working path and the protection path; in response to determining that the first plurality of events occurring during the first threshold detection duration is greater than a predetermined threshold, causing protection switching by the network element to cease for a first throttling duration of a first length; determining, by the network element, a second plurality of events occurring during a predetermined second threshold detection duration; and in response to determining that the first plurality of events occurring during the first threshold detection duration is greater than the predetermined threshold and that the second plurality of events occurring during the second threshold detection duration is greater than the predetermined threshold: determining, by the network element, a second throttling duration of a second length, the second length being greater than the first length; and causing protection switching by the network element to cease for the second throttling duration after the occurrence of the second plurality of events.
