Fault identification and prevention for PVC management in ATM networks

In order to meet the need of network management for emerging large complex heterogeneous communication networks, a distributed proactive self-adjusting management (DPSAM) framework was developed. The framework facilitates the incorporation of artificial intelligence and distributed computing technologies in building advanced network management systems. PMS, a PVC (permanent virtual circuit) management system for ATM networks, is developed based on DPSAM framework. PMS provides a scalable, end-to-end path management solution required for today´s ATM network and service management. It aims to assist network operators to perform PVC operations with simplified procedures and automatic optimum route selection. It also provides effective decision-making support for PVC fault identification and prevention. In this paper, PVC fault identification and prevention along with an overview of the DPSAM framework and PMS are presented
