ABSTRACT:
A system and method for performance monitoring of a telecommunications network that uses a layered performance monitoring structure. First, the monitoring points within the network are identified according to a customer request. The customer request is used to generate a service provisioning request, which indicates the path endpoints and the desired level of service. If the service is a digital data service and is supported for monitoring purposes, the network elements closest to the path endpoints are identified as primary monitoring points and activated, and based upon the desired level of service, a number of intermediate secondary points along the path are also identified but not activated. If the service is not a digital data service but the customer desires monitoring, then monitoring points are similarly identified and activated. Second, an end-to-end threshold is set for each service requiring thresholding per the service provisioning request. Third, previously identified secondary monitoring points are activated in the event that a degradation or failure is detected at the path endpoints. Upon an indication of trouble, the higher performance monitoring layers command the lower layers to perform trouble isolation processing, during which the lower layers determine which secondary monitoring points must be activated to determine the origin of the problem. The higher layers command the lower layers to commence activation.
