    • Even though the number of communication terminals or that of communication services exploited by the communication terminals is increased, load imposed on a node or a controller is to be less likely to be increased, while delay in processing is to be less likely to be produced. Each node of a communication system holds a plurality of packet handling operations which correlate the forwarding destination of a packet belonging to each flow with a set of collation rules that identify each flow, and forwards the received packet in accordance with the processing rules. In case the destination address of the received packet is such address indicating that the packet is to be multicast, the node multicasts the packet using the plurality of the processing rules the node holds.
    • 即使通信终端的通信终端的数量或由通信终端利用的通信服务的数量增加,施加在节点或控制器上的负载也不太可能增加,同时不太可能产生延迟的处理。 通信系统的每个节点保持多个分组处理操作,其将属于每个流的分组的转发目的地与识别每个流的一组对照规则相关联,并且根据处理规则转发所接收的分组。 在接收到的分组的目的地址是指示该组播组播的地址的情况下,该节点使用节点保存的多个处理规则来组播分组。

    • Silencing equipment provided with one or more flow channels through which cooling air flows has a flow channel forming member that forms the flow channel, and an acoustic absorbent member that is fixed to the flow channel forming member. A resonance type silencer is formed on a wall surface of the flow channel by providing a cavity for the resonance type silencer in the acoustic absorbent member and an aperture for the resonance type silencer in a portion of the flow channel forming member. The resonance type silencer sets a frequency of noise necessary to be reduced based on a peak frequency of noise generated by a fan. The silencing equipment further has a slide member which slides by a slide mechanism to adjust the area of the top of the aperture. The silencing equipment for electronic devices capable of cooling heat generating sections thereof with air has a small and simple structure and can improve a silencing effect by blowing air.

    • A method for analyzing sound transmission paths in a system from a sound source to a receiver in which the all sound paths are first identified from the sound source to the receiver. These sound paths include both structure-borne sound paths and air-borne sound paths. The transfer function from each path to the receiver is measured in terms of particle velocity vector by using a particle velocity sensor or a set of sound pressures by using a microphone array. The load at each path is directly measured or indirectly estimated in the actual source operation. The load at each path is multiplied by the transfer function from the path to the receiver, which represents the contribution of the path to the response at the receiver.
