Abstract: A network monitoring system that monitors a communication network including plural communication apparatuses and includes an obtaining part for obtaining a transmission traffic amount and a reception traffic amount of each port of the plural communication apparatuses, a determining part for determining whether the transmission traffic amount is no less than a first threshold and whether the reception traffic amount is less than a second threshold for each port of the plural communication apparatuses, a storage part for storing connecting path data of the communication network therein, an extracting part for extracting a loop affected path, and an outputting part for outputting data of the loop affected path.

Abstract: A clip for clamping an object (25) has a clip body (5) where a pair of clip members (1, 2) are pivotally connected to each other, clamping force increasing members (6, 7) for increasing a clamping force of the clip body; and fixing means (8) for supporting the clamping force increasing members on the clip body. The clamping force increasing members have slip prevention sections (6a, 7a) disposed between leading ends of the clip body and clamped by the clip body together with the object, and have also transmission sections (6b, 7b) connected to the slip prevention sections and fixed to the clip members by the fixing means, to cause the friction force that the slip prevention sections receive from the object to be transmitted to the clip body.

Abstract: A spanning tree creation unit creates a plurality of spanning trees based on the network topology, and registers the spanning trees to a spanning tree information table. A spanning tree selection unit selects a spanning tree wherein communication resources will be used most effectively, out of the plurality of spanning trees registered to the spanning tree information table. A node setup unit sets the mapping information which expresses correspondence between the requested virtual LAN and the selected spanning tree in each node.

Abstract: A device interfacer detects asynchronously occurring changes in function attributes in a device, and transmits the change attribute data to a database system. Then, a database system writes the changes to the database in a memory or an external storage device. A change point detection unit monitors the changes in the attribute record specified in the database, and asynchronously generates events for an object management software or the device interfacer corresponding to a change when any change occurs in the attribute record.

Abstract: Records corresponding to the label used in an abstract syntax are entered in a database, and decoding or encoding is performed while retrieving records one after another in accordance with their contents. Each record has a type identifier field for storing a type identifier name that identifies the type assigned to a label, an additional information field for storing additional information that additionally specifies the processing to be performed, a referenced label field for storing a label to be referenced, a value information field for storing value information, and a value field for storing a value.

Abstract: A multi-CPU system including a fault monitoring facility comprises a plurality of central processing units interconnected through a system bus and sending and receiving data through a plurality of bus interface units inserted in the system bus. A fault monitoring bus in parallel with the system bus is commonly accessed by the bus interface units. A bus interface unit which detects a fault notifies the other bus interface units simultaneously using the fault monitoring bus. Data-originating interface units and data-destination interface units receive fault information of the location and type of fault, which has occurred. Swift recovery from a faulty state is enabled.

Abstract: A firmware trace data acquisition method is constituted such that there are provided a monitoring part for monitoring firmware processes and a DMA part for transferring data to a trace data storing part in accordance with an instruction from the monitoring part, such that labels are attached to the plurality of process modules stored in a firmware storing part, and such that each of the process modules activated notifies the monitoring part of the label attached to itself. The monitoring part latches the label that it is notified of and monitors the execution of the corresponding process such that, when an abnormality is detected during the execution, the monitoring part controls the DMA part so as to transfer detailed data, derived from the process module corresponding to the label latched, to the trace data storing part, and such that, when there is no abnormality detected, the monitoring part allows the DMA part to transfer the latched label to the trace data storing part.

Abstract: A through-wall heat pump air conditioner having a total heat exchanger between the interior and exterior unit rooms is disclosed for recovering waste heat from the exhaust air. The conditioner includes two auxiliary dampers respectively provided between the exhaust air path and the heat exchanger and between the intake air path and the heat exchanger, whereby penetration of external air into the room is prevented during the halt state of the air conditioner.
