Abstract: A terminal includes a user interface that accepts an input of information used to determine whether to receive provision of an MEC service from an MEC server, or not, and a notification unit that notifies the network of information used by the network node to make a determination regarding provision of an MEC service from the MEC server.

Abstract: A network node includes at least a reception unit that collects information used for determining proximity of a plurality of terminals; and a control unit that operates to select at least one terminal that executes measurement report, from among the plurality of terminals, based on the collected information.

Abstract: A packet scheduling apparatus corrects an overhead amount between a DSL rate and a packet rate, converts DSL rate information to the packet rate, and shapes the IP packets from the Internet such that the IP packets are delivered at a transmission rate equal to or lower than the packet rate. An IP/ATM converter converts the IP packets from the packet scheduling apparatus to ATM cells. A DSL multiplexer has a DSL current rate detector for supplying DSL rate information indicative of a currently set DSL rate, and transmits the ATM cells from the IP/ATM converter or the IP packets from the packet scheduling apparatus to user terminals through DSL processing using telephone lines.

Abstract: In a client-cache-server system, the weight value of a first object which is maintained in the cache and linked to a second object maintained in the server is determined. Based on the weight value, a decision is made as to whether prefetching is necessary. If the decision indicates that prefetching is necessary, the second object is prefetched from the server to refresh the cache. A further decision is made as to whether update enquiry is necessary based on the weight value. If the further decision indicates that update enquiry is necessary, a message is sent to the server for inquiring whether the first object has been updated in the server. If the server responds with a reply that indicates that the first object has been updated, the second object is prefetched from the server to refresh the cache.

Abstract: The stream proxy server of the present invention includes a network information acquisition unit, a transport layer protocol control unit capable of transmitting and receiving data by using a plurality of transport layer protocols having a flow control function and different band sharing characteristics, a reception rate control unit for reading data at a rate determined by the transport layer protocol control unit, and a prefetch control unit for determining a rate of contents acquisition from an origin server and a transport layer protocol to be used based on information obtained from the network information acquisition unit and a buffer margin, and notifying the reception rate control unit of the determined rate and notifying the transport layer protocol control unit of the transport layer protocol to be used.
