OAM NAME STATE EVENT TRIGGER

摘要

The disclosed embodiments include a method, apparatus, and computer program product for improving network monitoring. For example, in one embodiment, current inaccuracies due to the imperfect counter frame injection error between ingress counters and egress counters is eliminated, by monitoring, using an ingress counter, for a time period that is slightly greater than the time it takes for a packet/frame to pass from one end to the other, for “no packets/frames”. In one embodiment, once this no packet time occurs, a signaling event is triggered. A notification is sent from the start of the path counter to the end of the path counter to start counting. A “stop counting/restart counting” signal is then sent from the start of the path counter to the end of the path counter the next time that no packets/frames are observed for the same period.

主权项

1. A method for improving network monitoring comprising:
monitoring, using a processor, protocol data units that are being communicated from a first network device to a second network device; identify a first time period when no protocol data units are being communicated from the first network device to the second network device for a period greater than a path delay time; responsive to identifying the first time period, transmitting a first signal from the first network device to the second network device to initiate counting of the protocol data units received at the second network device that are sent from the first network device; initiate counting, at the first network device, of the protocol data units that are transmitted to the second network device; identify a second time period when no protocol data units are being communicated from the first network device to the second network device for the period greater than the path delay time; responsive to identifying the second time period, transmitting a second signal from the first network device to the second network device to terminate counting of the protocol data units received at the second network device; and terminate counting, at the first network device, of the protocol data units that are transmitted to the second network device.
