摘要： A method of controlling data transmission in the ATM network which establishes simple modes of a network control for a case in which a plurality of cell loss priority levels are involved within the cells of a single virtual channel. The method includes the steps of declaring the traffic characteristics for either the loss intolerable cells only, or the loss intolerable cells and the loss tolerable cells separately, and carrying out at the network a connection admission control by estimating a cell loss rate on a basis of the declared traffic characteristics, such that the cell loss rate for either the loss intolerable cells only, or the loss intolerable cells and the loss tolerable cells separately in the multiplexed virtual channels is secured by the network on a basis of the estimated cell loss rate.

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： The present invention provides improved quality of service through data transmission rate control in a network. Data rate control may be in the downlink or uplink direction and may be statically or dynamically configured. Rate control may be implemented at varying points in the network including but not limited to at the wireless host, at the access point, at a separate device such as a server or at a separate location within the network. In one example of the present invention, a rate enforcement function is provided for identifying data packets to be enforced or identifying mapping between each packet and corresponding access point. Also, a rate decision function is also provided for determining the data rate to be enforced for each of the access points or each of the wireless hosts.

摘要： A node device and a label switched path loop detection method which are capable of detecting a label switched path loop efficiently and quickly are disclosed. In a node device for carrying out the label switching, an ingress node information is included in a message that is to be successively transmitted from the upstream side in order to set up a label switched path, and the fact that the message with the same ingress node information for the same packet flow will be received from a previous hop node that is different from before if the label switched path has a loop formed thereon is utilized. Also, at a time of transmitting a message for the purpose of setting up a label switched path, if a node at which the label switched path for that packet flow already exists on the upstream or downstream side is encountered, this already existing label switched path is traced along the same or opposite direction as the flow, and the label switched path is set up if no loop is detected after tracing to the end.

摘要： A network resource reservation scheme capable of making a resource reservation at the IP level according to the resource reservation protocol at a time of data packet transfer at the IP level using ATM networks. A node device requests a change of a virtual connection for transferring data packets to a prescribed virtual connection for providing a service which is capable of changing an amount of resource without reestablishing connections, when a prescribed message of a resource reservation protocol for that virtual connection is received, and transmits the data packets to the prescribed virtual connection established in response to the request. A node device determines a necessary amount of resource according to a requested quality of service described in a received reservation message of a resource reservation protocol. A node device then requests a change of an amount of resource reserved in a virtual connection for transferring data packets in order to reserve the necessary amount of resource in that virtual connection, and transmits the data packets to that virtual connection in which the amount of resource reserved therein is changed in response to the request.
