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： 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： In a communication network in which one master device and a plurality of slave devices are connected via a multiplexer to each other in a tree form with the master device provided at the vertex, the master device specifies each of the slave devices via the multiplexer according to a round-robin. Then the slave device transmits specific information for starting used for matching the sampling time to the master device according to the specified order. Finally, the sampling time is adjusted by executing a prespecified operation according to the specific information for returning returned from the master device in response to the specific information for starting.

摘要： A transmitting-receiving unit or a set of upper rank transmitting-receiving units and lower rank transmitting-receiving units are provided, and one or a plurality of circuits selected by a circuit selective switch unit from among many circuits are connected to the transmitting-receiving unit or the set. As a result, the burden of the control unit provided in the communication device is reduced. The maintenance of a route table which is used in transmitting packets from the highest rank station to the lowest rank station via other communication devices is made unnecessary by transferring the route table in order from the highest rank stations to the lowest rank stations.
