ABNORMALITY DETECTION DEVICE, COMMUNICATION ABNORMALITY DETECTION SYSTEM, COMMUNICATION ABNORMALITY DETECTION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce the number of inspection flows.;SOLUTION: An abnormality detection device 100 has: a controller that executes a procedure that a relay communication device 20a, which relays two communication devices 20b and 20c, specifies two links connected with the two communication devices 20b and 20c as a link pair, a procedure of specifying inspection devices of the number obtained by adding one to N (N is an integer equal to or more than one), which is the number of links where communication abnormalities occur simultaneously, from a plurality of inspection devices 200a-200c and 200d-200f respectively under the two links, and decides (N+1) inspection flows F11-F13 for (N+1) inspection device pairs, and a procedure of generating inspection target information including the decided inspection flows; a storage part that stores the inspection target information; and a communication part that transmits the inspection target information to one of the inspection device pair.;COPYRIGHT: (C)2012,JPO&INPIT
