A request packet of a large size is transmitted to the measurement target device, a response packet of the same size is received from the measurement target device and the round-trip time is measured. The usable communication bandwidth of the downlink is specified by a reciprocal of a value obtained by subtracting a reciprocal of the communication bandwidth of the uplink from a value obtained by dividing the round-trip time difference by the packet size difference.

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
