Abstract
Maintenance entities may be defined between customer and provider flow points to allow performance management to take place on an Ethernet network. The maintenance entities may be defined for access link, intra-domain, and inter-domain, and may be defined on a link or service basis. Performance parameters, including availability metrics, may be collected for the maintenance entities. The provision of such availability metrics in an Ethernet based solution to facilitate consistency of service management and operations for carriers transitioning to the Ethernet solution.
Claims18
A method of monitoring availability in an Ethernet network, the method comprising the steps of:
- associating performance thresholds with a maintenance entity defined between flow points on the Ethernet network;
- measuring performance parameters of the maintenance entity for a time interval, the performance parameters including frame metrics;
- and
- comparing one or more of the measured performance parameters to the performance thresholds to determine an availability metric of the maintenance entity.
A network device comprising:
- a processor, operations and maintenance (OAM) program code stored on a computer readable medium, the OAM program code operable when executed by the processor to collect availability metrics in an Ethernet network by:
- associating performance thresholds with a maintenance entity defined between flow points on the Ethernet network, measuring performance parameters of the maintenance entity for a time interval the performance parameters including frame metrics;
- and comparing one or more of the measured performance parameters to the performance thresholds to determine an availability metric of the maintenance entity.
A network device comprising:
- a processor, operations and maintenance (OAM) program code stored on a computer readable medium, the OAM program code operable when executed by the processor to collect availability metrics in an Ethernet network by:
- associating performance thresholds with a maintenance entity defined between flow points on the Ethernet network;
- the performance thresholds are being selected from a group including an Errored Second Threshold, a Severely Errored Second Threshold and an Unavailability Threshold;
- measuring performance parameters of the maintenance entity for a time interval;
- and comparing one or more of the measured performance parameters to the performance thresholds to determine an availability metric of the maintenance entity.
