Optimization mechanism for threshold notifications in service OAM for performance monitoring

A network device comprising:

• a network interface;
• and
• a control unit that provides an execution environment for a network performance monitoring module, wherein the network performance monitoring module is operable by the control unit to:
• monitor performance of a network between the network device and a different network device;
• determine, based on the monitoring, that the performance does not satisfy a performance metric, wherein the performance metric is one or more of a frame loss ratio performance metric or a link delay performance metric;
• responsive to the performance not satisfying the performance metric, perform enhanced network performance monitoring for a duration of time by at least determining a number of times the performance of the network transitions between not satisfying the performance metric and satisfying the performance metric during the duration of time;
• and
• while performing the enhanced network performing monitory, refrain from transmitting, using the network interface, to an element management system, and during the time duration, information about each time the performance of the network transitions between not satisfying the performance metric to satisfying the performance metric during the duration of time,
• wherein the network interface transmits, after the duration of time has elapsed and to the element management system, information about the performance of the network, the information including at least the number of times the performance of the network transitioned between not satisfying the performance metric and satisfying the performance metric during the duration of time.

A computer-readable storage medium encoded with instructions that cause one or more programmable processors of a first network device to:

• monitor performance of a network between the first network device and a second network device;
• responsive to determining that the performance of the network does not satisfy a performance metric, perform, for a duration of time, enhanced network performance monitoring, wherein the performance metric is one or more of a frame loss ratio performance metric or a link delay performance metric, and wherein performing the enhanced network performance monitoring for the duration of time comprises determining, with the first network device, a number of times the performance of the network transitions between not satisfying the performance metric and satisfying the performance metric during the duration of time;
• while performing the enhanced network performance monitoring, refrain from transmitting, from the first network device, to an element management system, and during the time duration, information about each time the performance of the network transitions between not satisfying the performance metric to satisfying the performance metric during the duration of time;
• and
• after the duration of time has elapsed, transmit, to the element management system, information about the performance of the network, the information including at least the number of times the performance of the network transitioned between not satisfying the performance metric and satisfying the performance metric during the duration of time.
