Abstract
Trees employing the following two elements are used to determine communicable ranges: paths within a transmission network that are set for data transfer between adjacent communicating devices; and the adjacent communicating devices located at both ends of the paths. The adjacent communicating devices corresponding to the roots of the trees are called adjacent communicating devices located at both ends of a path that has become incommunicable due to a fault within the transmission network.
