Proceedings of NOMS'96, April 1996.

In this paper, we study OAM measurement and alarm correlation methods in ATM networks. OAM fault management and performance management mechanisms are reviewed. We present the path intersection heuristics as the alarm correlation method to analyze the alarms collected by OAM measurements, and to find the congestion areas in ATM networks. We use simulation to evaluate the proposed heuristics. Besides, we analyze the congestion pattern in ATM networks by examing the simulation results. Finally, based on the proposed heuristics, we present three methods to choose the VPCs for rerouting in order to eliminate the congestion and we make a comparison among these three methods.
