摘要： In a network-device control system for controlling a network device such as a router, which is located between a communication terminal employed by a user and a server with which the terminal communicates, at a priority that has been set in advance for the user or for an application, an event notification device detects that a user has logged in to the communication terminal or that the user has launched a predetermined application from the communication terminal and reports the user identifier or the application identifier to a network-device controller. The latter acquires user priority or application priority on the basis of the reported identifier and, in accordance with the priority, controls the router on the communication path between the communication terminal and the server.

摘要： A service assignment apparatus sets an appropriate service in a service-request-incompatible apparatus as a network element so as to guarantee the service in the entire network. A service-request-compatible apparatus processes a received network-service request, and provides a service. A network-information collection unit in the service assignment apparatus collects information on a service-provision state of the service-request-compatible apparatus. A target-apparatus determination unit determines a service-request-incompatible apparatus based on the collected information on the service-provision state. A service mapping unit determines a service which the service-request-incompatible apparatus can provide, based on the information on the service-provision state and information on the determined service-request-incompatible apparatus. A service setting unit sets the service in the service-request-incompatible apparatus.

摘要： A testing apparatus includes a storage to store a communication log including a communication time and a response confirmation number of packets, and a processing circuit to generate an additional packet having a communication time and a response confirmation number between two consecutive packets having an interval greater than or equal to a threshold value in the communication log. The interval may be an interval of the communication times of or, an interval of the response confirmation numbers of the two consecutive packets. The testing apparatus also includes an interface unit to send the packets stored in the storage and the additional packet to a destination at a time interval based on communication times thereof.

摘要： A next sequence number, which is a sequence number that a next packet should have, is compared with the sequence number of a current packet, an identifier of a previous packet is compared with the identifier of the current packet, and a delay is judged to be a simple delay when the next sequence number matches the sequence number of the current packet and the identifier of the previous packet is followed by the identifier of the current packet. Or the delay is judged to be caused by a retransmission when the identifier of the previous packet is not followed by the identifier of the current packet.

摘要： A network looping detecting apparatus has an increased real-time operation capability for network looping detection and also has scalability. The network looping detecting apparatus has a count information acquiring unit for periodically acquiring count information which is counted up when the lifetime of a packet has elapsed, from a network device of a network to be monitored for network looping. The network looping detecting apparatus also has a looping detecting unit for detecting network looping from the count information. Specifically, the network looping detecting apparatus detects network looping based on the fact that when a packet loops due to network looping, the lifetime of the packet elapses, and the count information is counted up.
