Abstract
The connectivity of a strongly connected network may be destroyed after link damage. Since many networks are connected by directed links, the reachability may be restored by altering the direction of one or more of the links and thus reconfiguring the network. The location of the failed link must first be determined. In this paper, we examine new methods to determine the location of failed links and nodes in networks. A routing test approach is proposed and the conditions under which communication networks may be tested are discussed. Finally, an adaptive algorithm and a heuristic algorithm that can locate a single failed link or a single failed node are presented.
