In order to achieve the above object, there is provided a network measurement configuration apparatus connected to a network having a plurality of measurement devices arranged therein, which measures traffic data of the network based on a measurement rule, comprising, a receiving means which receives a user request including path information and a measurement type, a measurement device selecting means which selects a measurement device responsible for a measurement based on the user request, and a measurement rule setting means which sets a measurement rule in the measurement device thus selected.

Abstract: The present invention provides a technique suitable for configuration management of a network for which the number of logical network layers can be set. A network management apparatus 10 receives an address definition information file defining logical hierarchical structure of an IPv6 network 20, from an operator through a definition information reception unit 103. A configuration analysis unit 104 generates management tables defining hierarchical relationships of logical networks, based on the address definition information file and IP addresses collected respectively by an information collection unit 102 from network elements belonging to the IPv6 network 20, and registers the management tables into a management DB unit 101.

Abstract: A method, apparatus and computer program for displaying partial information related to network equipment connected to a network being managed by a network management system. The partial information is required for network management to be conducted from the network equipment. A managed terminal is included in each network equipment. The network management system collects management information from each network equipment and stores management information therein. When conducting network management, the managed terminal sends a request for network management. The network management system in response transfers a program for managing the network to the managed terminal. The transferred program informs the network management system of the identification of the managed terminal. Partial information is transferred to the managed terminal based on the identification. The managed terminal then displays the transferred partial information.

Abstract: The present invention provides an attribute value sampling device that obtains communication path establishing control information transmitted and received between data transfer devices, and sets monitoring on the basis of the communication path establishing control information. The attribute value sampling device obtains control information for establishing the communication path sent between the data processors, and extracts setting information relative to the obtaining the attribute value from the obtained communication path establishing control information, and obtains the attribute value from information passing through the path by using the extracted setting information.

Abstract: A method, apparatus and computer program for preferentially displaying partial information related to one of a plurality of network equipment connected to a network being managed by a network management system. The partial information is required for network management to be conducted from the network equipment. The network management system collects and stores management information from each network equipment. When conducting network management, a managed terminal sends a request for network management to the network management system, which transfers a program for managing the network to the managed terminal. The transferred program informs the identification of the managed terminal to the network management system which transfers partial information to the managed terminal based on the identification. The managed terminal then displays the transferred partial information so that network management can be conducted from the network equipment.

Abstract: When a problem occurs in communication carried out by a user, information concerning the problem is notified to the user. A network management system transfers a problem notification program to a network device adjacent to a place experiencing the problem. The problem notification program notifies “communication impossible” to a terminal of a transmission source of data output from an output port of the network device.

Abstract: A time stamping part and a packet storing part are separated from each other. To simplify data transfer from the time stamping part to the packet storing part, the time stamping part adds time information after a captured packet, and outputs the packet directly through a port for the packet storing part. The packet storing part captures all packets sent from the time stamping device regardless of their destinations, thereby preventing the time stamping part from performing extra processing.

Abstract: An identifier of each management module is obtained on the basis of management information commonly handled by network management information and administration management information, and management information of the two is collected on the basis of the identifier, and a client/server configuration map is generated, and a network map corresponding to the map is displayed from the display element of the generated configuration map on the basis of the correspondence of the two, and the client/server configuration is displayed in relation to the network map, and an administrative role and a related object node can be identified easily.

Abstract: In a network management system in which a management application performs management operations on respective managed objects in a communication network, a template management portion stores a processing sequence described by the user into a database, and when a start request is given from a management application, a processing sequence execution portion issues a table generating request to an internal table generating portion. The internal table generating portion generates tables and then delivers an end report and the generated tables to the processing sequence execution portion, so that the processing sequence execution portion executes management operations for managed objects on the basis of the set of tables. The aforementioned processing is repeated whenever a start-up request arises from the management application. Thus, a user not only can describe behavior of management services without consciousness of a program language but also can execute management operations by describing the behavior.
