A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method to trigger a pause reduction component, the method comprising:receiving a pause message on a first network element, wherein the pause message is from a second network element and indicates that data should not be transmitted by the first network element; and
in response to receiving the pause message, triggering the pause reduction component on the first network element when a characteristic of the first network element is above a pause reduction threshold, wherein the pause reduction component reduces an effect of the pause message and the pause reduction threshold is based on at least one of a particular number of pause messages, an inadequate drain rate of a queue associated with the second network element, or a queue occupancy of the queue associated with the second network element.
