    摘要: A router apparatus 5 is provided with an ATM switch, an IP controller for performing routing control as a controller for layer 3, plural kinds of interfaces which are individually provided to plural transmission paths in which various communications are performed, and a cell multiplexing/demultiplexing unit, and manages the cell communications between respective parts on the basis of identification information. The input packet is subjected to IP processing in an interface to be converted to a cell in a common format, and the cell is serially multiplexed with a cell from another interface on a cell basis, and transmitted to the ATM switch at the cell multiplexing/demultiplexing unit. Each interface and each cell multiplexing/demultiplexing unit sets and switches the identification information for the header portion of the packet and the cell to be communicated by using a table in which the corresponding relationship of the identification information is registered.

    摘要: In a system in which communication is performed among a plurality of devices having a mechanism of disassembling a packet into ATM cells to send them and a plurality of devices having a mechanism of assembling the received ATM cells into the packet, a frame is prevented from being lost owing to change of virtual connections in the course of transferring the frame, improving reliability of the communication on the packet level. When the switch receives a request for change of switching, it does not processes that request at once, but confirms that the cell located at the boundary of the frame has been processed, before processing the change request, so as to protect the frame. When the switch receives a request for change of switching, it protects a frame by multicasting the cells to both destinations before change and after change, for a given period of time.

    摘要: For reducing the scale of a multiplexer, a lower speed ATM interface block, an interface block for SDT mode circuit emulation, and an interface block for UDT mode circuit emulation perform processing for terminating services provided by lower speed transmission lines accommodated therein, and part of AAL processing, which is pre-processing depending on a service, for generating ATM cells from signals received by a terminated service, and send the processed signal to a higher speed line interface using a previously assigned time slot on a time-division bus. The higher speed line interface once stores the signals received from the time-division bus in a buffer, and subsequently performs certain processing including a common portion for respective signals for generating therefrom ATM cells in which the signals are stored in payloads. The generated ATM cells are multiplexed and transmitted onto a higher speed transmission line.
