摘要： PROBLEM TO BE SOLVED: To provide a network fault detecting device for detecting a generated L2 loop and a point where it is generated.
SOLUTION: The network fault detecting device is achieved as one of functions of a terminal in a network. The network fault detecting device acquires packet reception statistical information per port of a relay device, and extracts a port having a large packet reception amount per unit time. If a certain relay device has one mass reception port, the device determines that an L2 loop has been generated on the downstream of the port, and if a certain relay device has two mass reception ports, the device determines that the two ports form a loop and an L2 loop has been generated.

摘要： PROBLEM TO BE SOLVED: To perform understanding and non-communication confirmation even in a packet sequence, where correspondence between a data packet and an ACK (Acknowledgement) packet does not satisfy, with respect to a understanding confirmation technology in a network communication system. SOLUTION: An input section 101 receives a packet flowing on a network. A packet information acquisition section 102-1 acquires, from the received packet, packet information including transmission source address information, destination address information, order control information (sequence number), and approval response information (ACK flag, confirmation response number). On the basis of the packet information, a non-communication/understanding detection section 102-2 detects a understanding state including non-communication or understanding between a host, that is a transmission source of the received packet, and a host of the destination. By combining a change tendency of the order control information with the approval response information, it is detected whether non-communication occurs between the host that is the transmission source of the received packet and an apparatus itself or between the apparatus itself and the host that is the destination of the received packet. An output section 104 outputs the conduction state. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To enable prompt detection of an L2 loop point without modifying an existent relay unit, and further, even on the occurrence of L2 loop, to enable prompt identification of the point of occurrence thereof.
SOLUTION: A method is provided for searching an L2 loop fault point produced in any of a plurality of units of search objects being disposed in a network, by means of a network fault point detection unit. The network fault point detection unit broadcasts a plurality of packets having different originating MAC addresses, and obtains, as statistic information, information of learning ports of the above plurality of different originating MAC addresses respectively learned in the plurality of units of search objects. From the obtained statistic information, it is obtained whether the learning port(s) of the plurality of different originating MAC addresses is either only one or two. Then, the unit of the search object having two learning ports of the plurality of different originating MAC addresses is decided to be the L2 loop fault point.
