摘要： A distributed memory computer system periodically performs memory copy among a plurality of computers by using general-purpose communication control devices and a transmission line of the CSMA/CD type. A master computer periodically generates a synchronizing packet, and transmits data for memory copy and normal data in a time slot immediately after the transmission of the synchronizing packet. Each computer other than the master computer transmits the data for memory copy and the normal data in its own time slot after the elapse of a predetermined time. The respective computers complete their transmissions within predetermined times. Since the time slots are assigned to the respective computers, the number of computers which may compete with each other on a transmission line can be restricted and each computer can be assured a periodic opportunity to transmit data.

摘要： A network interface apparatus connected between a LAN adaptor possessed by a computer and a transceiver provided on a network includes a buffer memory for storing data, a first control circuit for communicating with the LAN adaptor, a second control circuit for communicating with the transceiver, and a processor for controlling the first and second control circuits to control the transfer of data between the LAN adaptor and the transceiver. The processor causes the buffer memory to store transmit data transmitted from the LAN adaptor and transmits the stored transmit data in the buffer memory to the transceiver in a transmission time zone which is allotted beforehand. The transmission time zone is determined by the processor on the basis of the reception of a synchronizing packet which is transferred on the network. Receive data received from the transceiver is selected by the processor so that only the selected receive data is sent to the LAN adaptor. A reference for the selection may include a protocol type, a port number on TCP/IP or the like.

摘要： It is designed to connect a duplicated LAN to a network terminal such as a controller having a standard serial or parallel interface, a computer having only one LAN interface, or a computer having only one communication line interface. The network interface apparatus for connecting a network terminal and a duplicated LAN comprises a device for controlling interfaces with the network terminal and the LAN transmission line of each of the duplicated LAN, a buffer, and a sending device to both, and the data from the network terminal is buffered in the buffer, and when the buffered data reaches a fixed amount, the data is sent to both LANs of the duplicated LAN. On the other hand, with respect to the data received from each LAN transmission line of the duplicated LAN, only the data which is judged as earlier arrival data is sent to the network terminal.
