Application of a Multimedia Service and Resource Management Architecture for Fault Diagnosis

Abstract

Nowadays, the complexity of global video products has substantially increased. They are composed of several associated services whose functionalities need to adapt across heterogeneous networks with different technologies and administrative domains. Each of these domains has different operational procedures; therefore, the comprehensive management of multi-domain services presents serious challenges. This paper discusses an approach to service management linking fault diagnosis system and Business Processes for Telefónica’s global video service. The main contribution of this paper is the proposal of an extended service management architecture based on Multi Agent Systems able to integrate the fault diagnosis with other different service management functionalities. This architecture includes a distributed set of agents able to coordinate their actions under the umbrella of a Shared Knowledge Plane, inferring and sharing their knowledge with semantic techniques and three types of automatic reasoning: heterogeneous, ontology-based and Bayesian reasoning. This proposal has been deployed and validated in a real scenario in the video service offered by Telefónica Latam.

Ontology-Based Method for Fault Diagnosis of Loaders

“…The ontology modelling process in G. Medina-Oliva’s research was similar to this paper, which used Protégé to construct ontology coded in OWL, and built Semantic Web Rule Language (SWRL) rules to diagnose faults. Alfonso Castro et al [ 28 ] designed a multimedia service and resource management architecture for fault diagnosis. This architecture includes three types of automatic reasoning: heterogeneous, ontology-based and Bayesian reasoning.…”
