    摘要： According to some embodiments, systems and methods for binding dynamic host configuration and network access authentication are provided related to, inter alia, interactions between a PAA (PANA Authentication Agent) and a DHCP (Dynamic Host Configuration Protocol) server, such as, e.g., for synchronization between the PANA SA state and the DHCP SA state, such as, e.g., maintaining synchronization when a connection is lost. In some embodiments, systems and methods for binding network bridge and network access authentication are also provided related to, inter alia, interactions between a PAA and a layer-2 switch, such as, e.g., for avoiding service thefts and the like (such as, e.g., MAC address and/or IP address spoofing) in the context of, e.g., the above. In some other embodiments, systems and methods for bootstrapping multicast security from network access authentication protocol are also provided related to, inter alia, key management for protected IP multicast streams, such as, e.g., to avoid IP multicast streams unnecessarily received and/or processed by unauthorized receivers connected to the same layer 2 segment as authorized receivers in the context of, e.g., the above.

    摘要： A radio terminal or gateway capable of executing the AV/C protocol on the datalink protocol which starts communications after setting up a logical channel on a radio network is disclosed. The radio terminal or gateway transfers data packets according to the stored correspondence information among the protocol identifier, the channel identifier that is set up for the radio terminal or gateway, and the channel identifier that is set up for a correspondent radio terminal or gateway, where the correspondence information is obtained through an exchange of signaling packets containing the channel identifier indicating a logical channel that is set up for transferring the data packets and the protocol identifier indicating the AV control protocol.

    摘要： A first acquisition unit acquires each of the resources defined by the scenario, from locations depending on identifiers of the resources. A judging unit judge, when a resource having same identifier and structure as the resource acquired is existent in the cache storage, erases the resource, the identifier thereof, and the receipt time information from the cache storage, and when not existent, stores the acquired resource in association with the identifier thereof and the receipt time information of the bookmark instruction, in the cache storage. A second acquisition, when the identifiers of the resources specified by a first scenario are existent in the cache storage, acquires the resources from the cache storage according to the receipt time information corresponding to the first scenario and identifiers of the resources, and when not existent, acquires the resources from a location depending on the identifiers.
