    摘要: A caching method for caching network contents of a packet transfer network including a packet relay for relaying accesses of clients to servers supplying contents, and a network contents cache device are disclosed. Accesses from the clients to the servers are monitored by the said packet relay to determine a cache priority on the basis of a product of relaying path lengths from the packet relay to the server and frequency of access from the client to the servers and the network contents cache device preferentially caches a response to the access to the server having higher cache priority.

    摘要: A method for transferring a series of layer-3 packets through an ATM network composed of a plurality of ATM switches is disclosed. An ingress gateway determines whether a packet flow has been registered and, when the flow has not been registered, determines a transfer route. A connection setup cell is transmitted to a next-hop ATM switch to ensure a connection dedicated to transfer of tho series of packets. Then, a series of packets is transferred to the next-hop ATM switch through the connection after the connection has been set up.

    摘要: The present invention relates to a data collection system and a data collection method in a sensor network, enabling sensor modules to consume lower amounts of power. The base station transmits data collection request signals to one or more sensor modules which are lower than the base station by 1 in a tree structure. Each sensor module which has received the data collection request signal transfers the signal to one or more sensor modules which are lower than the module by 1. The base station regards the transfer of the signal as ACK for the data collection request signal transmitted therefrom to the sensor module which is lower than the base station by 1. The transmission of a data collection acknowledgement signal starts from a sensor module at the low-order end. When a sensor module receives the data collection acknowledgement signal from a downstream sensor module which is lower than the module by 1, the module transmits the signal to an upstream sensor module which is higher than the module by 1. The downstream sensor module regards the transmission of the signal as ACK for the data collection acknowledgement signal transmitted therefrom, and enters standby mode. In this manner, the sensor modules enter standby mode in sequence starting from the sensor module at the low-order end. Thereby, it is possible to achieve reductions in the frequency of signal transmission while maintaining reliable data communication. Thus, each module consumes lower amounts of power.

The scheduler (103) includes (c1) a shuffler (201) which shuffles an order of precedence in a first request transmitted from the input to transfer the packet, (c2) a schedule algorithm (202) which determines the output, based on the first request having the order of precedence having been shuffled by the shuffler, and produces a second request to transfer a packet which second request is associated with the first request having the order of precedence having been shuffled by the shuffler, and (c3) a re-shuffler (203) which turns an order of precedence of the second request to be identical with the order of precedence in the first request as found before having been shuffled by the shuffler, and returns the thus turned order of precedence back to the input.

    摘要: In an ATM network, each logical subnetwork comprises a server for resolving an ATM address using layer-3 address of request message and routing a packet to the network by using a layer-3 address of the packet. A source client examines a layer-3 header of a packet to determine whether its mode of transmission is connection-oriented or connectionless, and transmits the packet, if it is connectionless, to the server for causing it to route the packet through the network, and transmits, if the packet is connection-oriented, an ATM address resolution request message to the server. The source client receives a reply message from the server containing a resolved ATM address, and transmits a signaling message containing the resolved ATM address to the network to establish a connection. Over the established connection, the source client transmits data packets.

    摘要: An event processing system which, even if large quantities of processing requests are generated from applications, suppress the load growth of setting of a processing rule and a dispatch rule in event processing distribution is provided.The event processing system includes a plurality of local systems 100 which receive an event from an event source 150 and send a processing result of the event to an application server 160, and a dispatch rule distribution server 170 which distributes a dispatch rule to the local systems 100. When receiving a processing rule from the application server 160, the local system 100 generates the dispatch rule including own local system 100 as a dispatch destination of the event and sends it to other local system 100 via the dispatch rule distribution server 170. When the event is received from the event information source 150, the local system 100 dispatches it to other local system 100 according to the dispatch rule.
