Fault detection in telecommunication networks based on a petri net representation of alarm propagation

Abstract

This paper presents a new use of safe Petri nets and its partial order semantics, in the field of telecommunication network management. Petri nets are used to provide both a model and an algorithm in fault management domain. First, a model of fault and alarm propagation, based on 1-safe Petri nets, is defined. Then an algorithm, based on net unfolding, is designed. This study leads to a generic supervisor, which can be easily distributed on a set of sensors.
