A fault effect assessment architecture of advanced intelligent network

This paper presents a fault effect assessment architecture of an advanced intelligent network for monitoring service operation status by using a damage assessment method. The fault effect assessment architecture has three types of management domains-physical, logical, and functional object layer. Each domain is closely correlated by the damage assessment model used to estimate the deterioration level of the network functionality when physical network entities are faulty. The purpose of this paper is to achieve the enhanced fault management of not only the network entities but also the network functionality by applying a damage assessment concept to the area of intelligent network fault management.
