Quantifying and verifying network reachability is important for security monitoring and auditing as well as many aspects of network management such as troubleshooting, maintenance, and design. Although attempts to model network reachability have been made, feasible solutions to computing network reachability have remained unknown. In this paper, we propose a suite of algorithms for quantifying ...

Today's computer networks are large and complex. Their dayto-day operation and maintenance can benefit from the support of an expert system, mainly as an aid in troubleshooting. Network troubleshooting has characteristics, like incomplete data, high rate of events, simultaneous presence of several problems, which raise interesting problems in the development of an expert system. DANTES is an ex...

We consider computer assisted troubleshooting of complex systems, for example of a vehicle at a workshop. The objective is to identify the cause of a failure and repair a system at as low expected cost as possible. Three main challenges are: the need for disassembling the system during troubleshooting, the difficulty to verify that the system is fault free, and the dependencies in between compo...

Abstract A goal of advanced packaging design performance is to reduce power and achieve better control heat electromagnetic interference. Materials efficient include the use gold (Au) wire, copper (Cu) alloy, gold/silver (Au/Ag) plating, solder, low-k epoxy dry-film polymers, silicones polyimides. Material purity verification contamination during production process a prerequisite ensure high yi...

Troubleshooting search system aims at extracting relevant information to solve the problem at hand. It is often the case that documents in troubleshooting system includes an abundant amount of domain-speci c categories. However, the useful information about the domain-speci c categories, such as relationship between words and categories and relationship between categories, is not fully utilized...

In the current telecommunication scenarios operators have to cope with fast technological changes while increasing operational efficiency, i.e. diminishing operational expenditures and, at the same time, maximising performance of the networks. In this paper we present an automated troubleshooting tool for cellular networks, based on Bayesian networks, which will contribute to improve operationa...
