摘要： PROBLEM TO BE SOLVED: To reduce an enormous work cost that a network administrator bears. SOLUTION: Only when a request is reconstructed, the request being formed of a plurality of request packets obtained by dividing the request, the request is transmitted to a survey target node that returns response packets obtained by dividing a response. When no response packet has been received at all from the survey target node, determination processing is carried out to determine that any of the request packets has been discarded on a first route from a surveying node as a transmission source of the request to the survey target node. When one or more response packets have been received from the survey target node but the response can not be reconstructed, determination processing is carried out to determine that any of the response packets transmitted from the survey target node has been discarded on a second route from the survey target node to the surveying node as the transmission source of the request packets.

摘要： PROBLEM TO BE SOLVED: To improve real-time properties and scalability in network loop detection. SOLUTION: A count information acquisition means 1a periodically acquires count information counted up when the lifetime of a packet exceedingly elapses from pieces of network equipment 3a, 3b for composing a network 2 to be monitored. The network 2 to be monitored is a network monitored by a network loop. A loop detection means 1b detects the network loop from the count information acquired by the count information acquisition means 1a. More specifically, when the packet is looped by the network loop, the lifetime exceedingly elapses and the count information is counted up. By utilizing it, the network loop is detected.

摘要： PROBLEM TO BE SOLVED: To provide a technology of particularizing even an abort position before and after a relaying apparatus or the like in operation on a layer 2 without the need for many hosts and relieving a time, a cost and a labor up to fault recovery. SOLUTION: When a packet sequence arrives in the relaying apparatus SW or the like wherein a speed change takes place from a high speed to a low speed in a state that the packet interval is packed, packet residence (transfer waiting of packets) takes place in the relaying apparatus SW or the like. On the occurrence of packet abort before the relaying apparatus SW or the like, the relaying apparatus SW or the like transfers packets by packing a spread packet interval due to the packet abort in advance. However, on the occurrence of the packet abort after passing through the relaying apparatus SW or the like, packets are transferred while the spread packet interval due to the packet abort is not packed, then a terminal T1 or T2 observes the packet abort and the packet interval at the packet abort so as to particularize at which of a high speed block and a low speed block the packet abort takes place.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for detecting network failures that detects the generation of an L2 loop and its generation point. SOLUTION: The apparatus is achieved as one function of a terminal in a network. The apparatus acquires statistical information of packet reception for each port of a relay apparatus, and extracts a port having a large packet reception quantity per unit time. When a certain relay apparatus has one large reception port, the apparatus determines that an L2 loop is generated in a downstream direction of that port, when another certain relay apparatus has two large reception ports, the apparatus determines that a loop is formed by the two ports and an L2 loop is generated.
