Abstract
The objective of this research is to investigate the common link in diagnostics of different networks. Are there any underlying common expertise and strategies that are applicable to various connection-based networks? If so, how is the general expertise related to network-specific expertise? Why is it significant to identify and figure out the general expertise? To support out method, we developed an expert system which helps to interpret the alarms delivered from a multiplexer network, determine the faulty behavior of the network, and offer recovery suggestions. Our work classified the diagnostic expertise into (i) general expertise and (ii) customized or network-specific expertise. The former consists of certain general strategies and common sense in network diagnostics, while the latter consists of specific technology know-how of a network built with a particular product family of multiplexers. Since the general expertise is also applicable to other types of connection-based networks, it is hoped that our work can provide a foundation to build other network diagnostic expert systems.

Keywords: Expert system; network diagnostics; fault management; multiplexers.
