    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： 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.

    摘要： A communication network system includes a communication line, a plurality of communication stations each having a node coupled to the communication line and a network controller coupled to the stations for controlling routing for communication messages between nodes. In one embodiment, the messages are sent from plural terminals connected with each node along with communication performance prerequisites. The communication performance prerequisites for a communication message are discriminated in the node which receives the message. Traffic in various routes between the nodes is continually measured in the communication stations and the measuring results are stored in a database storage unit. Future traffic in the various routes is predicted on the basis of the information on the continually measured traffic by the use of a predetermined algorithm and stored in the storage unit for use in determination of routes for communication messages on the basis of the result of the communication performance prerequisites discrimination and predetermined criteria with respect to the updated information on the predicted traffic in the storage unit.
