    摘要： Access points for supporting wireless communications, a packet transmission device, and terminals for handing-over between service areas are provided. An existing terminal is provided with respect to this access point for performing a Quality of Source (QoS) guarantee. Accordingly, when a new terminal is handed over to be engaged in wireless communications with this access point, the priority of the packet associated with the existing terminal and/or new terminal is changed.

    摘要： A communication apparatus transmits an authentication frame to an authentication apparatus and receives a response frame for response to the authentication frame from the authentication apparatus so that an authentication process is performed for the communication apparatus by the authentication apparatus. In the communication apparatus, a transmitting section transmits an authentication frame to the authentication apparatus using a multicast address as a transmission destination address, and if a reception determining section determines that the response frame is not received from the authentication apparatus, a transmission destination address changing section changes the transmission destination address from the multicast address to a broadcast address, and the transmitting section transmits the authentication frame that has the transmission destination address changed to the broadcast address to the authentication apparatus.

    摘要： The present invention includes a repeater and a server for controlling access, from a terminal of an outside network, to the server of an inside network. The repeater and the server permit a packet transmission from the terminal to the server under limited conditions. When the server acknowledges a connection for the permitted packet, transmission conditions for packets to be sent to the server are loosened. Subsequently, packet transmission between the terminal and the server is controlled under the loosened transmission conditions. As for encrypted packets, the server decodes the encrypted packets and notifies the repeater of relevant information.

    摘要： A resource management server that manages information concerning the resource reservation status and the information of groups of all electronic equipments connected to hubs. When an electronic equipment is newly connected to a port of one of the hubs, the electronic equipment issues a resource request and the group information to the resource management server. The resource management server sets up a network path between the newly connected electronic equipment and the other electronic equipments belonging to the same group as the newly connected electronic equipment, and judges if the resource request can be accepted on the setup network path.

    摘要： A terminal comprises a packet receiving unit, a packet sending unit, a link-state detecting unit that detects a link-up to a switching device, a configuration-change notifying unit, and a resource reservation table. When the link-state detecting unit detects a link-up, the terminal notifies network configuration information and network resource reservation information to a management device. When a link state is changed, the management device can immediately manage the network based on the latest network configuration information and the latest network resource information.
