By increasing, the complexity of chips and the need to integrating more components into a chip has made network –on- chip known as an important infrastructure for network communications on the system, and is a good alternative to traditional ways and using the bus. By increasing the density of chips, the possibility of failure in the chip network increases and providing correction and fault tol...

Modern distributed applications pose increasing demands for high availability, automatic management , and dynamic connguration of their software systems. This paper presents the architecture of Sampa, a System for Availability Management of Process-based Applications, which aims at fullll-ing these requirements. The system has been designed to support the management of fault-tolerant DCE-based ...

U sers are increasingly deploying high-speed networks in distributed computer systems. These networks may have stringent real-time and fault-tolerance requirements. FDDI (fiber distributed data interface) 1 is a 100-Mbps local area network based on a token ring media access control protocol defined by ANSI and OSI standards. It has built-in provisions for fault-tolerance and real-time communica...

The reliable execution of a mobile agent is a very important design issue in building a mobile agent system and many fault-tolerant schemes have been proposed so far. Security is a major problem of mobile agent systems, especially when money transactions are concerned . Security for the partners involved is handled by encryption methods based on a public key authentication mechanism and by secr...

Automated aircraft control has traditionally been divided into distinct "functions" that are implemented separately (e.g., autopilot, autothrottle, flight management); each function has its own fault-tolerant computer system, and dependencies among different functions are generally limited to the exchange of sensor and control data. A by-product of this "federated" architecture is that faults a...

facts technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. statcom is oneof the most important facts devices used in the parallel compensation, enhancing transient stability andetc. since three phase fault is widespread in power systems, in this paper statcom is used...

In this paper, several Artificial Intelligence (AI) techniques such as Rule-Based Reasoning (RBR), Bayesian Networks (BNs), Neural Networks (NNs), Case-Based Reasoning (CBR), Qualitative Reasoning (QR), and Model-Based Reasoning (MBR) are described. Then an automated management system prototype is presented. Finally, a hybrid approach to automated network and system management is proposed. Howe...

In this paper we present a Distributed Intelligent Fault Management (DIFM) system for communication networks. The overall architecture of the proposed system is based on a distributed cooperative multi-agent paradigm, with probabilistic networks as the framework for knowledge representation and evidence inferencing. We adopt the management by delegation paradigm [5] for network monitoring and i...

considering that once-through benson boiler is one of the most crucial equipment of a thermal power plant, occurrence of any fault in its different parts can lead to decrease of the performance of system, and even may cause system damage and endanger the human life. in this paper, due to the high complexity of the system's dynamic equations, we utilized data-based method for diagnosing the faul...

Network fault management has been a focus of research activity with more emphasis on fault localization – zero down exact source of a failure from set of observed failures. Fault diagnosis is a central aspect of network fault management. Since faults are unavoidable in communication systems, their quick detection and isolation is essential for the robustness, reliability, and accessibility of a...
