Abstract
A method and an apparatus for locating a fault within a token ring network are described. The apparatus comprises a number of detectors, each of which is positioned at a location between a pair of neighboring network stations. Each detector maintains an indication of whether beaconing data is detected at the monitored location. After a period of time, a fault identifier, in the form of a Network Management Module (NMM), can identify the location of a network fault by locating successive indications, maintained by successive detectors, which differ from each other.
