    摘要： A data transmission apparatus is provided for transmitting data received from a user terminal device through a plurality of networks to a destination, the user terminal device executing communication using an Internet protocol. The data transmission apparatus includes a routing table storing information relating a destination address of the data and addresses of the plurality of networks; an information table storing static and dynamic information about the plurality of networks; and a selection unit selecting one or the plurality of networks, through which the data transmission apparatus transmits the data to the destination, based on the static and dynamic information. The data transmission apparatus enables data transmission through the appropriate network by selecting the appropriate network based on the static and dynamic information about the plurality of networks.

    摘要： A buffer control system is a system for implementing both a priority control process and a shaping process of cells with a hardware configuration of a small size in a network routing fixed-length packets which are respectively composed of transfer data and control information added to the transfer data, and to which priority information is assigned, according to the control information. If a cell written to an empty area of a cell buffer is a prioritized cell, and its expected output time is a time slot, an address where the cell is stored in the cell buffer is arranged in a time slot in a prioritized cell entry memory. When it reaches the time to read the cell stored in the time slot, the address stored in the time slot is written to an output list chain, and the cell is read from that address. The empty area of the buffer is managed using a free list chain.

    摘要： A packet switch interfacing between a WAN and a LAN accommodating a terminal includes an address table storing a relation between an address of the terminal and an input port receiving a packet transmitted from the terminal, and an address learning unit for storing in the address table the relation between the source address of the received packet and the input port receiving the received packet. Further the packet switch includes a SW unit for effecting control to transmit the received packet according to whether or not stored in the address table, and then transmit the received packet to the WAN when a packet having a source address identical with the destination address of the received packet has not been received from the LAN.
