摘要:
According to this invention, it is possible to display the overall configuration of a network and, at the same time, an important part of the network in detail according to the objective of monitoring so as to be able to grasp/monitor the important part of the network in detail, while globally grasping/monitoring the network configuration, for the purpose of an efficient monitoring operation on the network configuration. A network configuration management apparatus 100 for managing the configuration of a network 101 formed by connecting a plurality of network devices comprises a topology information acquiring section 11 for acquiring topology information on each of the network devices and a degree of importance determining section 12 for computationally determining the degree of importance of each of the network devices, using the topology information acquired by the topology information acquiring section 11. The apparatus 100 displays a network map on the basis of the computationally determined degrees of importance.
摘要:
Connections included in the topology of a lower-order layer of a plurality of layers are grouped according to device setting information of a plurality of devices composing a communication network with a communication function having a hierarchical structure composed of the plurality of layers, and an information reach range in a higher-order layer is generated. Then, the topology of the higher-order layer is generated based on the obtained information reach range.
摘要:
An apparatus generates configuration group information by classifying, based on first log information storing messages outputted by a first plurality of configuration items of a first system, into first configuration groups each including one or more configuration items that have outputted messages having a commonality. The apparatus generates relation class information that defines, in association with the first configuration groups, first one or more message propagation relations. The apparatus classifies a second plurality of configuration items of a second system into second configuration groups included in the first configuration groups, based on the configuration group information and second log information storing messages outputted by the second plurality of configuration items, and applies second one or more message propagation relations that are associated, by the relation class information, with third configuration groups included in the second configuration groups, to the second plurality of configuration items.

A method and device of outputting information related to a communication error including obtaining a communication log containing a communication message delivered between a second device and a third device in accordance with a control message transmitted from a first device to the second device. A non-transmitted control message specifying procedure reading out control message association information containing identification information of a control message delivered between the second device and the third device in association with a control message addressed and transmitted from the first device to the second device, and specifying a non-transmitted control message based on the read-out control message association information and the communication log.
摘要:
A computer system has a dual structure including a current system and an auxiliary system. When the current system stops because of server down, a setting module of the auxiliary system acquires an operation log and an operation management procedure from the current system and analyzes the operation log to specify to which part of the operation management procedure has been completed. The setting module performs comparative analysis of the operation log of the current system and communication log. The setting module extracts, from a result of the comparative analysis, information for returning the auxiliary system to a state of work at the stop of the execution of the current system. To resume the stopped work, the setting module sets the information in the auxiliary system.

摘要:
A tripod constant velocity universal joint including an outer joint member having three axial track grooves in an inner periphery and roller guide surfaces formed in opposing side walls of each track groove. A tripod member has three radially projecting trunnion journals and rollers that rotate around respective trunnion journals through a plurality of needle rollers and are received in the track grooves of the outer joint member. Each roller is guided on an outer peripheral surface by the roller guide surfaces. Contact between the roller and roller guide surfaces is circular having a contact ratio that is 1.01 or higher. The contact ratio is defined by a widthwise length of the contact ellipse formed by the roller contacting the guide surface relative to the width of said roller.

A tripod constant velocity universal joint including an outer joint member having axially extending track grooves formed at three circumferentially equispaced positions in the inner periphery. A tripod member has a trunnion barrel adapted to be fitted to a shaft for torque transmission and trunnion journals radially projecting from three circumferentially equispaced positions in the trunnion barrel, and rollers rotatable around the associated trunnion journal for rotation through a plurality of needle rollers and received in the track grooves. Each roller is guided at its outer peripheral surface by roller guide surfaces formed in opposite lateral walls of the track groove. The torsional strength of the tripod member and the smallest outer diameter portion of the shaft are set to be substantially equal. Also, the surface pressure on the trunnion journals in rolling contact with the needle rollers is allowed up to a predetermined value.

A propeller shaft has a metal pipe (1) with a joint element (3) joined at an end thereof. A fiber reinforced plastic layer (5) having a thickness that achieves a flexural rigidity satisfying a required natural bending frequency is formed on an outer circumference of the metal pipe (1) satisfying a static torsional strength required as a propeller shaft. The fiber reinforced plastic layer (5) has an interface strength between the reinforcing fiber and the matrix within a range of 20 to 200 MPa as measured by the microdroplet method.
