Abstract
A network element includes a plurality of ports configured to connect to a network; and circuitry configured to configure a service with a second network element in the network where the service utilizes a plurality of resources on the network element and the second network element, configure alarm suppression on the service, detect faults associated with the plurality of resources for the service and suppress reporting of alarms based on the alarm suppression, and remove the alarm suppression responsive to a period of time where there are no detected faults associated with all of the plurality of resources. The alarm suppression can be controlled by one of Alarm Reporting Control (ARC) and Auto In-Service (AINS).
Claims17
A network element comprising:
- a plurality of ports configured to connect to a network;
- and
- circuitry configured to:
- provision a service with a second network element in the network where the service utilizes a plurality of resources on the network element and the second network element,
- configure alarm suppression on the service, wherein the alarm suppression is service-level Alarm Reporting Control (ARC) or Auto In-Service (AINS) applied for the service as a whole such that a fault on any one of the plurality of resources prevents alarm reporting for all of the plurality of resources for the service,
- detect faults associated with the plurality of resources for the service and suppress reporting of alarms based on the alarm suppression, including correlating fault information across the plurality of resources comprising near-end faults, far-end faults, and reverse faults to provide a single-ended independent ARC/AINS function without requiring a communications channel to convey fault status along a service path, and
- remove the alarm suppression responsive to a period of time where there are no detected faults associated with all of the plurality of resources at both the network element and the second network element such that the service is up end-to-end across a network domain in both directions before any of the plurality of resources exits a not-reported state.
A method implemented in a network element comprising a plurality of ports configured to connect to a network, the method comprising steps of:
- provisioning a service with a second network element in the network where the service utilizes a plurality of resources on the network element and the second network element;
- configuring alarm suppression on the service, wherein the alarm suppression is service-level Alarm Reporting Control (ARC) or Auto In-Service (AINS) applied for the service as a whole such that a fault on any one of the plurality of resources prevents alarm reporting for all of the plurality of resources for the service;
- detecting faults associated with the plurality of resources for the service and suppressing reporting of alarms based on the alarm suppression, including correlating fault information across the plurality of resources comprising near-end faults, far-end faults, and reverse faults to provide a single-ended independent ARC/AINS function without requiring a communications channel to convey fault status along a service path;
- and
- removing the alarm suppression responsive to a period of time where there are no detected faults associated with all of the plurality of resources at both the network element and the second network element such that the service is up end-to-end across a network domain in both directions before any of the plurality of resources exits a not-reported state.
A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to execute steps of:
- communicating with a plurality of network elements in a network;
- configuring a service between two network elements of the plurality of network elements where the service utilizes a plurality of resources on the two network elements;
- configuring alarm suppression on the service, where alarms associated with faults detected on the plurality of resources for the service detected at the two network elements are suppressed and not reported, wherein the alarm suppression is service-level Alarm Reporting Control (ARC) or Auto In-Service (AINS) applied for the service as a whole such that a fault on any one of the plurality of resources prevents alarm reporting for all of the plurality of resources for the service, and wherein fault information across the plurality of resources comprising near-end faults, far-end faults, and reverse faults is correlated to provide a single-ended independent ARC/AINS function at each of the two network elements without requiring a communications channel to convey fault status along a service path;
- and
- receiving new alarms associated with faults detected on the plurality of resources for the service subsequent to passing of a period of time where there are no detected faults associated with all of the plurality of resources on the two network elements such that the service is up end-to-end across a network domain in both directions before any of the plurality of resources exits a not-reported state.
