Abstract: A network-provisioning data generating method, by which manual data registration can be prevented so that correct network provisioning data can be collected and registered in real time, and a transmission device, which is constituted according to the generated network structure, are provided.

Abstract: A method and system for controlling data delivery and reception, which alleviate the processing workloads imposed on management systems and reduce the hardware and software resources required in management systems. Each time a status message arrives from network subsystems, a data storage unit in a management system stores the received information, together with a reception timestamp. At regular intervals, or on an on-demand basis, a data requesting unit in a terminal station issues a data delivery request message to the management system, including a reception time specification to qualify the data records to be delivered. In response to the request, a data retrieval unit in the management system searches its local data storage to extract the requested data records whose reception timestamps are not earlier than the given reception time specification. The data records found are then supplied to a data transmission unit.

Abstract: The present invention discloses a technique of determining actual effect information actually related to cause information occurring in a multiplexer having the function of multiplexing communication lines, and the redundancy function.

Abstract: A method and apparatus for building network configuration database, which eliminates manual data collection and verification tasks and thereby reduces the time and labor costs related to such tasks. A device data collection unit requests a plurality of transmission units on the network to report how they are configured. This request may be initiated at regular intervals or triggered by an external source on demand. Template data is previously prepared by modeling possible configurations of various types of transmission units, and stored in a template data storage unit. A data area management unit reserves a plurality of data storage areas in the physical connection database, according to the template data in the template data storage unit. A process decision unit stores the device configuration data collected by the device data collection unit into corresponding data storage areas reserved in the physical connection database.

Abstract: For the purpose of controlling a communication network used for communication of information and having a plurality of transmission units and a plurality of circuits making connections between the plurality of transmission units, a network control apparatus is provided which rearranges the communication network, by using a plurality of transmission units and a plurality of circuits, into at least one terminal network of at least four terminals.
