PROBLEM TO BE SOLVED: To provide a system capable of coping with an abnormal condition in a network by the detection thereof, by supervising an illegal multicast routing packet in a network system operated by use of a PIM-SM multicast routing protocol.;SOLUTION: Each of network supervision devices NM1-NM5 supervises the multicast routing packet, such as a bootstrap message packet and a PIM register message packet, and notifies an integrated supervision device 100 of abnormal information when abnormality is detected. The integrated supervision device 100 displays the configuration of the network system on a GUI as a map, and displays the abnormal information to discriminate it on the map. Further, on receiving a user operation to set the interception of an abnormal bootstrap message and a PIM register message exceeding a threshold, the integrated supervision device issues an instruction to the network supervision device.;COPYRIGHT: (C)2010,JPO&INPIT
