摘要： A communication network includes a plurality of user networks that accommodates IP terminals and does not perform a call control function, a core network (a call control network) that is located among the user networks and performs a call control function and a call management function, and a gateway that connects the user networks to the core network. The gateway receives a communication request packet from the user network or a data packet that is initially transmitted, and analyzes the packet. Thus, the gateway establishes a necessary call in the core network to allow an IP packet to pass through the core network.

摘要： An asynchronous transfer mode (ATM) communication network system is constructed by connecting a plurality of ATM terminal communication devices to each other through connections. Each ATM terminal communication device has a transmission function to transmit an output ATM cell and a receiving function to receive an input ATM cell. Each ATM terminal communication device includes memory including a connection control table having, for each ATM terminal communication device, an assigned virtual path identifier and an assigned virtual channel identifier; and an ATM cell transmission section for transmitting an output ATM cell including the virtual path identifier assigned to the ATM terminal communication device and the virtual channel identifier assigned to other ATM terminal communication devices, the virtual path identifier indicating the ATM terminal communication device as a transmitter of the output ATM cell, and the virtual channel identifier indicating the other ATM terminal communication device as a receiver of the output ATM cell. Each ATM terminal communication device further includes an ATM cell receiving section for comparing a virtual channel identifier of an input ATM cell with the virtual channel identifier assigned to the ATM terminal communication device, trapping the ATM cell when the virtual channel identifier of the input ATM cell matches the virtual channel identifier of the ATM terminal communication device, and discarding the input ATM cell when the virtual channel identifier of the input ATM cell does not match the virtual channel identifier of the ATM terminal communication device. The ATM terminal communication devices form a point to multipoint connection for a virtual path identified by the virtual path identifier of the output ATM cell transmitted from the ATM terminal communication device.

摘要： A multicast connection control apparatus provided in a branching-and-consolidating node connecting a source terminal to a plurality of destination terminals for branching information over the forward connection or consolidating information over the backward connection in a multicast connection ATM network system includes a congested status management table for managing congested status in all RM cells and a controller. The controller transmits only an uncongested status RM cell transmitted thereto last over the backward connection when all the connections in a sequence are found to be in the uncongested state. The controller also transmits only a congested status RM cell over the backward connection when one of the connections is found to be in the congested state and cancels the subsequent transmission of the congested status RM cells in the same sequence over the backward connection.

摘要： A node functions as an inter-ring connection node connected to an inter-ring connection link in a communication system including a plurality of inter-ring connection links connected between adjacent ring networks. The node includes: a flow-information-pass determination unit that decides which of the inter-ring connection links a reception frame passes through, based on flow information that is stored in the frame for identifying flow to which the frame belongs; and a forwarding-destination-port decision unit that decides that a forwarding destination of the reception frame is an inter-ring connection link to which the own node is connected when the inter-ring connection link decided by the flow-information-pass determination unit is the inter-ring connection link to which the own node is connected, in the case where a destination of the reception frame is in an adjacent ring network.
