Abstract: The present disclosure includes a network element comprising a first card configured to receive a duplicatively split first signal comprising a data component and a management component, and further configured to receive and transmit a duplicatively split second signal, and a similar second card. The network element also includes a selector configured to select either the first card or the second card to receive the management component of the first signal and to detect a change in designation between the first card and the second card to transmit the second signal. The selector is also configured to modify the selection to select the card designated to transmit the second signal to also receive the management component of the first signal. The disclosure also includes associated methods and systems.

Abstract: According to one embodiment, a method may include communicating an alarm suppression indication trigger message from a maintenance end point to an alarm indication suppression generator. The method may further include communicating, by the alarm indication suppression generator in response to receiving the alarm indication trigger message, an alarm indication suppression message to at least one flow point that has alarm indication suppression enabled for the maintenance end point such that the alarm indication suppression message is received by at least one other maintenance end point upstream of the maintenance end point.

Abstract: In accordance with the present disclosure, a method may include receiving a delay measurement message frame at a responder maintenance end point from a controller maintenance end point. The method may further include writing an ingress time value to the delay measurement message frame upon receipt of the delay measurement message at the responder maintenance end point. The method may also include generating a delay measurement response frame based on the delay measurement message frame, the delay measurement response frame comprising an egress timestamp field having a value equal to the difference between a time at which the delay measurement response frame is transmitted from the responder maintenance end point and a time represented by the ingress time value. The method may additionally include transmitting the delay measurement response from the responder maintenance end point to the controller maintenance end point.

Abstract: According to one embodiment, a method may include detecting an occurrence of a fault for a component of a network element having a maintenance entity provisioned thereon. The method may further include transmitting alarm indication suppression messages to components for which the maintenance entity was configured to transmit alarm indication suppression messages in response to detecting the occurrence of the fault.
