Abstract: In an asynchronous transfer mode switch, a plurality of queues is provided for accumulating transfer cells, and a queue assignment processing section, receives a message for establishing a connection and assigns to the connection one of the queues having a forwarding rate close to a declared rate included in the message and not exceeding the declared rate.

Abstract: In an ANS used for a television conference between calling and destined conference room terminals accommodated in an ATM network, an address of each conference room terminal is stored in an address database as address resolution data which have no hierarchical structure and which therefore uniquely define each conference room terminal. A priority level of each conference room terminal is also stored in the address database and is referenced on occurrence of congestion so as to determine whether or not a connection is released during a conference. Reservation data may be stored in the ANS together with topology data and connection data.

Abstract: A monitor (102) receives a returned response message, and stores the state of the link directed to the NE that returned the message as a successful transmission, and then repeats the same operation at arbitrary intervals. When the monitor can not receive the response message after placing a certain interval, it stores the link as an unsuccessful transmission. At this point, if all the links for a particular NE are in the unsuccessful state, the monitor informs an NMS (151) of a fault in that NE. If the NE truly has the NE fault, other NEs that also have the links to that fault NE inform the NMS of the fault. Thereby the NMS itself does not need to do the monitoring. The NMS only collates fault information with topology information stored in a topology information storage (153) and can judge that a particular NE is out of communication and control.

Abstract: An information terminal (1), a control device (3), and a plurality of direction sensing devices (5) constitute a radio wave transmission source location specifying system. The control device (3) specifies a location to be specified from where a target radio wave with a predetermined frequency is transmitted, by communicating with the information terminal (1) to be used by a user and the direction sensing devices (5) via a communication line (2). At this time, the information terminal (1) is provided from the control device (3) with a remote control function enabling remote control of operations of the direction sensing devices (5).

Abstract: In an internet protocol switch including a controller and a switch section controlled by the controller, the switch section includes an input cell buffer for receiving cells input to the switch section. The output of the input cell buffer is closed during a transition time from a selected flow connection linked to the input cell buffer and the controller, to a cut through connection linked to the input cell buffer without linking to the controller. Then, after the cut through connection is established, the output of the input cell buffer is opened.
