Processing circuitry is configured to receive, via one of the physical ports, a data packet from the network and to decide, responsively to a destination identifier in the packet, whether to deliver a payload of the data packet to the host processor via the host interface or to forward the data packet to the network via another one of the physical ports.

Abstract: When a data request is sent from a master device in master-slave communication, a slave device determines whether a piece of data requested by the data request among data stored on the slave device side has been updated after previous transmission of the piece of data. If the piece of data has been updated, the slave device sends the updated piece of data as a response to the data request. If the piece of data has not been updated, the slave device suspends a response to the data request. Thus, a communication system is built which can reduce network processing load and the volume of communication data in the case where the master device periodically acquires data from the slave device.

Abstract: Telecommunication network management operations are performed based on accessing network management data (NMD) files via GUIs and general purpose computers including a network management system (NMS) server, and automatic routines for transferring binary NMD files between the general purpose computers and remote network elements (NEs) being managed. A system user produces configuration files at the NMS server for NEs using a network management GUI, and the hardware of NEs automatically complete the network management operations indicated by the NMD files transferred to them from the NMS server and produce their status files to the NMS server. The network management GUI displays network status based on the latest NE status files at the NMS server. This provides direct, binary file transfer based NMS communication that avoids the complexity and restrictions of intermediate messaging protocols or transaction languages and conversions thereof.

Abstract: A communications processing section of a management apparatus sends a request for malfunction information via the Internet to one or more electrical devices being managed. A database manager of the management apparatus refers to data stored in a database and updates the record of the electrical device therein.

In this way, despite the management apparatus centrally manages the malfunction information of each electrical device, a peak quantity of the malfunction information received by the management apparatus can be suppressed and the workload on the management apparatus can be relieved, as opposed to the case where each electrical device sends the malfunction information at its own timing.

Abstract: An object location monitoring system includes beacons that are spatially distributed throughout an area to be monitored. The beacons transmit interrogation signals that are received and echoed by transponders that attach to moveable objects. Each beacon retransmits its interrogation signal, and any transponder response thereto, to a receiver that measures a time difference between the two signals. This time difference reflects the signal propagation time, and thus the distance, between the beacon and the transponder. One such receiver preferably analyzes the retransmitted signals of multiple (e.g., 50 to 100) beacons. A triangulation method is used to determine the location of each transponder based on the transponder's distances from a set of beacons. In one embodiment, the transponders are provided as or within disposable ID bracelets worn by patients, and are used to track the locations of the patients within a hospital.
