US 7,889,744 B2 · Method and apparatus for automatic synchronization of monitoring points of a network management system along a permanent virtual circuit

Abstract

A method and apparatus for automatic synchronization of monitoring points for a network management system (“NMS”) along a permanent virtual circuit (“PVC”) is disclosed. A NMS in an asynchronous transfer mode (“ATM”) network coupled to a plurality of ATM switches is operative to monitor each of the plurality of ATM switches storied in a monitoring service object corresponding to a PVC. The NMS receives at least one notification from at least one ATM switch of the plurality of ATM switches indicating an ATM switch has been added or removed from the PVC. In response to the at least notification, the NMS adds at least one ATM switch to the monitoring service object or removes at least one ATM switch from the monitoring service object.

A method for synchronizing monitoring points in an asynchronous transfer mode (“ATM”) network for a rerouted permanent virtual circuit (“PVC”), comprising:

receiving a customer-defined starting and ending point for a PVC;
assigning a first value of a location variable to a location of the starting point of the PVC;
determining whether the first value of the location variable is equal to a location of the ending point;
storing the first value of the location variable in a monitoring service object;
determining a virtual path identifier/virtual channel identifier (“VPI/VCI”) corresponding to the PVC to identify a location of an ATM switch that is located along the PVC path after the starting point of the PVC;
assigning a second value of the location variable to the determined location of the ATM switch;
storing the second value of the location variable in the monitoring service object;
determining whether the second value of the location variable is equal to the location of the ending point;
storing a first set of data comprising a plurality of notifications for ATM switches that have been added to the PVC;
determining whether each ATM switch of the first set of data is adjacent to a location of an ATM switch stored in the monitoring service object, the monitoring service object comprising a plurality of ATM switches along the PVC;
storing a location of each ATM switch of the first set of data that is determined to be adjacent to a location of an ATM switch stored in the monitoring service object in the monitoring service object;
storing a location of each ATM switch of the first set of data that is determined to not be adjacent to a location of an ATM switch stored in the monitoring service object in a second data set;
and
storing the second data set for subsequent processing.
