摘要： An ATM switch includes a plurality of stages in which each stage has basic switches and the stages are interconnected. The ATM switch includes M×N basic switches per each stage and a part for interconnecting between the stages. The M×N basic switches are divided into N groups. The part connects an output port of each basic switch at a front stage to M input ports of the basic switches at a back stage. At the output port, a wavelength-multiplexing part is used, and, at the input port, a wavelength-demultiplexing part is used. Further, a wavelength-switching part for switching optical signals of M wavelength-multiplexed optical signals arriving from the M wavelength-multiplexing part and outputting the switched wavelength-multiplexed optical signals to the M wavelength-demultiplexing part is used.

摘要： In an access network using optical switches, communications between an OLT and ONUs are established without a photoelectric conversion performed at an optical switching unit.The OLT controls the downlink optical switch SW(DOWN) to sequentially select each ONU in slots arranged in a discrete manner, and transmits a Discovery Gate message. Upon receipt of the Discovery Gate message, each ONU consecutively transmits Register Request messages. The uplink optical switch SW(UP) sequentially switch signals from ONU#1 through ONU#128 in the slots arranged in a discrete manner, and outputs the signals to the OLT, Some of the Register Requests transmitted from the respective ONUs pass through the SW(UP), and reach the OLT. Based on the received Register Requests, the OLT determines the timing of transmission for the ONUS, and notifies the ONUS of the timing of transmission through a Gate message.

摘要： A packet switch has pluralities of incoming and outgoing trunks, a data memory accessible from them in common, and FIFO memories each provided in each of input and output circuits. Data from the incoming trunks is written into and read out from the buffer memory for transfer to the outgoing trunks, on a time-shared basis, to perform packet switching between trunks of different data transfer rates. Furthermore, the packet switch has an arbiter for detecting process requests from the input circuits and an arbiter for detecting process requests from the output circuits, so that priority control is effected for servicing the requests. As a result, dynamic allocation of access to the buffer memory to the input and output circuits is permitted.

摘要： An OVPN user register an L1 signal type information which is used in the user's device in an OVPN terminating device in advance together with an IP address and a VPNID which are allocated to the user's device. Registered contents are notified to other OVPN terminating devices which control the same VPNID as that of the user's device. Otherwise, when a calling connection request arrives from the user's device, the registered contents are notified other OVPN terminating devices which control the devices which receive the notification. By doing this, it is possible to handle a request by the user for changing the setting for the signal format which is employed in the user's device quickly. Also, it is possible to realize an OVPN which can perform a process for a calling connection request from the user efficiently and improve an operability for the user.

摘要： In a best effort type service of an ATM communication network for circulating an RM cell, a subscriber's switchboard holds the latest route information, and the RM cell is used for short distance communication between the communication terminal and subscriber's switchboard. For a plurality of connections accommodated in the switchboard and using a transmission line or a route in common, information on the allowable transmission rate, the actual transmission rate, the full bandwidth and full input bandwidth of the transmission line or the route, and the number of connections using in common the transmission line are collected and held. A transmission rate acceptable for the caller's terminal is calculated for each connection on the basis of the information. An increase of a memory capacity is restricted by providing a common buffer and managing it by a pointer value. A list of cells which have arrived simultaneously is prepared, and is managed by the pointer value. The cells are sent out at different timings so as not to be discarded. Even when congestion is solved, the restriction is not quickly lifted but control is enforced in consideration of the increment of the cell flow rate immediately after the lift. Convolution calculation is made only once for determining the overall mean cell loss ratio and consequently the number of calculations is reduced.
