摘要： A communication system includes a station-side terminal apparatus and multiple subscriber-side terminal apparatuses connected to the station-side terminal apparatus. The station-side terminal apparatus is configured to, in response to receipt of a packet from a subscriber-side terminal apparatus, a packet indicating whether data distribution is required, identify the subscriber-side terminal apparatus that has transmitted the packet, and transmit a packet indicating an address for which whether the transfer of distribution data is required is designated to the subscriber-side terminal apparatus based on whether data distribution is required. Each subscriber-side terminal apparatus is configured to, in response to receipt of a distribution packet, if the distribution packet has the address for which whether the transfer of distribution data is required is designated, transfer the distribution packet to host apparatuses accommodated thereto or prohibit the distribution packet from being transferred to the host apparatuses accommodated thereto.

摘要： A bus load distributing method suitable for data communications equipment and a bus switching control device for data communications equipment. The data communication equipment includes plural buses, a bus connecting unit for interconnecting the plural buses, and a control unit for connecting physically and selectively each module to one among the plural buses. The control unit connects plural modules to a bus to recognize, distribute and reduce the load on the bus. The control device also switches a bus to be connected in accordance with the traffic of each module to optimize the bus load.

摘要： An amount-of-data identifying portion identifies the amount of data transmitted by referring to a specific portion in the upper layers of the information transmitted from the terminal of a LAN, and a bandwidth control line monitor portion calculates the band which is necessary for communication. Communication between LANs is executed through the number of wide area network interface portions which is determined on the basis of the calculated band. In the case that the communication is performed after securing the band corresponding to the traffic characteristics (transfer speed, etc.) declared to the network, the amount-of-data identifying portion identifies the amount of data transmitted by referring to a specific portion in the upper layers of the information transmitted from the terminal of a LAN, a traffic characteristics calculator calculates the traffic characteristics on the basis of the amount of data transmitted, a traffic characteristics declaring portion declares the calculated traffic characteristics to the network, and the network communicates on the basis of the declared traffic characteristics.

摘要： A method of transmits HDLC data which is in conformance with a high-level data link control procedure via an asynchronous transfer mode network. The method includes the steps of deleting at least flags from the HDLC data before assembling ATM cells which are transmitted via the asynchronous transfer mode network, disassembling the ATM cells which are received via the asynchronous transfer mode network, and inserting at least flags to the disassembled ATM cells to restore the original HDLC data.
