Fault management of infrastructure networks

In this paper, an approach for suitable fault management in traffic information networks, focusing on the isolation of network faults in infrastructure networks, will be introduced. We will show, that modelbased diagnosis is an efficient method for finding explanations consisting of the underlying fault events of system failures. A fault management system based on these concepts will be discussed and evaluated. precipitation, humidity, radar units, cameras, and electronic beacons as the interface between mobile and fixed traffic information networks. Since the first roadside devices have been used in 1926 [3], the heterogeneity of today's traffic information networks is of an astounding magnitude. Therefore, a prominent role of global and regional TMCs is the maintenance of the network performance. Especially fault management aspects, i.e. the detection, isolation, correction, and administration of network faults, is an important task, whose significance increases with the size of traffic information networks. This paper introduces a new tool for the isolation of network faults.
