— We present an approach to fault management based on an architecture for distributed and collaborative network management as developed in the CELTIC project Madeira. It uses peer-to-peer communication facilities and a logical overlay network facilitating decentralized and iterative alarm processing and correlation. We argue that such an approach might help(More)
Quality of Service (QoS) monitoring of end-user services is an integral and indis p ensable p art of service management. However in large, heterogeneous and complex networks where there are many services, many types of end-user devices, and huge numbers of subscribers, it is not trivial to monitor QoS and estimate the status of Service Level Agreements(More)
This paper describes a novel approach to network management topologies where multiple customized topologies are self-configured, self-optimized , and maintained automatically by the underlying network of elements. An implementation of these self-forming management topologies as developed in the Celtic European research project Madeira is described. The(More)
— The Madeira project addresses a novel approach for the management of network elements of increasing number, heterogeneity and transience. As next-generation networks exhibit major challenges for today's centralized network management systems, we investigate the feasibility of a peer-to-peer (P2P) approach, facilitating self-management and dynamic behavior(More)
Management of outer edge domains is a big challenge for service providers due to the diversity, heterogeneity and large amount of such networks , together with limited visibility on their status. This paper focuses on the probabilistic fault diagnosis functionality developed in the MAGNETO project, which enables finding the most probable cause of service(More)
