Abstract: A network element configured to support Connectivity Fault Management (CFM) for Operation, Administration and Maintenance (OAM) includes circuitry configured to track faults in the CFM via a defect indication variable that includes multiple bits wherein each bit is one of a certain priority level of a plurality of priority levels and a reserved value, and, responsive to one or more of detection of a new fault and clearing of an existing fault, update the defect indication variable accordingly based on a corresponding priority level of the new fault or the existing fault.

Abstract: Systems and methods for adaptively re-adjusting meter rates of processor cores of a multi-core processor having ports grouped in a Link Aggregation Group (LAG) are provided. A method, according to one implementation, includes a step of obtaining a metering allocation setting for a service on each of a plurality of processor cores. The plurality of processor cores is configured to receive data traffic via a plurality of data ports. The data ports are configured to be grouped so as to serve as a single logical port from the perspective of an external component. The method further includes a step of determining an anticipated metering need associated with the service on each of the processor cores. Also, the method performs an adaptive metering procedure that includes automatically adjusting the metering allocation setting for the service based on the respective anticipated metering need.

Abstract: Systems and methods for tracking and reporting the existence or absence of faults in a Network Element (NE) or node of a network, network domain, or Maintenance Domain (MD) are provided. A method, according to one implementation, includes a step of tracking the existence or absence of a plurality of faults in a NE within a network domain. Each of the plurality of faults is categorized in one of a plurality of priority levels. In response to a detection of one or more new faults in the NE or a rectification of one or more old faults in the NE, the method further includes the step of updating a fault indication variable that individually signifies the existence or absence of a fault at each of the priority levels.
