    Abstract: A fault diagnosis unit (42) of a fault diagnosis apparatus (4) performs a fault diagnosis of a communication network (2) with a probabilistic inference algorithm using information on the communication network (2) having been gathered by an NW monitoring unit (41). A diagnosis result determining unit (43) determines test items for confirming and determining a diagnosis result of the fault diagnosis. A test performing unit (44) performs a confirmation test of the determined test items. The diagnosis result determining unit (43) determines a likelihood of the diagnosis result of the fault diagnosis based on a result of the confirmation test.

    Abstract: One aspect of the present invention is an information processing system that includes a computing machine installed in a computing machine base, and a first transmitting/receiving apparatus connected to the computing machine, a second transmitting/receiving apparatus installed in a user base that is used by a user, and a device connected to the second transmitting/receiving apparatus, and a control apparatus configured to control connection between the first transmitting/receiving apparatus and the second transmitting/receiving apparatus. In the information processing system, the control apparatus is configured to change the connection between the first transmitting/receiving apparatus and the second transmitting/receiving apparatus, and copy the state of the pre-change computing machine from the pre-change computing machine into the post-change computing machine.

    Abstract: A communication system includes three or more nodes and a multi-core fiber having a plurality of cores, the multi-core fiber being used in at least a partial segment of the connection between the nodes is provided. One node of the nodes is connected to the multi-core fiber and includes a connector configured to add and drop a signal to and from an allocated core exclusively allocated from among the cores as a communication path between the one node and another node of the nodes and/or configured to relay a signal transmitted through another core of the cores allocated for communication between other nodes in the multi-core fiber connected to the one node, and a relative positional relationship between a connection position of the allocated core in which a signal is added or dropped in the connector and a connection position of another core in which a signal is relayed in the connector is the same for all of the nodes connected to the multi-core fiber.
