Abstract: An apparatus includes a collection device, a determining device, and an estimating device. The collection device collects information and flow rates of flows circulated in a network and structural information of the network. The determining device finds links through which the flows pass from the information and the network structural information, and determines the flows based on degrading and non-degrading threshold values. The estimating device, from a set of the links through which the quality-degraded flows pass, outputs a subset having a minimum element number and including a link through which an arbitrary flow among the quality-degraded flows passes. The determining device changes, for a set of the quality-degraded flows that pass a link through which a given quality-non-degraded flow passes, the non-degraded flow number threshold value depending on number of elements of a set. When this threshold value becomes high, the estimating device finds a non-degraded link.

Abstract: A method and a system for stabilizing the sight line of a chip component being carried on two discs, for stabilizing delivery of the chip component between the two discs, and improving and stabilizing the inspection accuracy in the visual check of the chip component. This is achieved by employing a mechanism for carrying the chip component while supporting it on the horizontal plane of the first rotary disc and then carrying the chip component while suction-holding it on the vertical plane of the second rotary disc. When the chip component is carried on the first rotary disc, the upper surface and one side face of the chip component are imaged by first and second cameras. When the chip component is carried on the second rotary disc, the lower surface and the other side face of the chip component are imaged by third and fourth cameras.

Abstract: In a quality degradation (QD) portion estimating method on a network, a passive measuring unit connected with a management target network measures E2E flow quality (FQ) data on a route from a transmitting terminal connected with a different network to a receiving terminal connected with the management target network and upstream FQ data on the route from the transmitting terminal to the passive measuring unit in the management target network. A QD portion estimating section connected with the management target network collects E2E FQ data and upper stream FQ data measured by said passive measuring unit. A detecting section detects as a QD flow in the management target network, a flow related to the E2E FQ data that does not show degradation of FQ, for the upstream FQ data related to the same transmitting and receiving terminals, from among the E2E FQ data which show the degradation of FQ.

Abstract: A QoS degradation point estimation device (S1) includes a flow set decision unit (3), a flow quality information collection unit (1), a path information collection unit (2), a flow link table management unit (4), and a QoS degradation point estimation unit (8). Before generating a flow link table which associates QoS of a flow going through a network with a link the flow passes through, the flow set decision unit (3) preferentially selects a flow which passes through almost ½ of the total number of links of the network as a flow to be registered in the flow link table. The flow quality information collection unit (1) collects information of the QoS of the flow. The path information collection unit (2) collects path information of the network. The flow link table management unit (4) generates the flow link table based on the information of the QoS and the path information. The QoS degradation point estimation unit (8) estimates a QoS degradation link based on the flow link table.

The quality degradation point estimating method has: (A) determining a test flow set for estimating a quality degradation point; and (B) estimating the quality degradation point in the directed link set by sending the test flow set to the network. The (A) step includes a step of setting the flow, which passes through a partial set as a part of the directed link set, as the test flow and adding the set test flow to the test flow set. The test flow is sent from the test terminal on the network to a predetermined node in the partial set. A response is obtained at the predetermined node, and the response is sent from the predetermined node to a predetermined terminal.
