摘要： A packet ring network system is disclosed which enables plurality of packet rings to perform packet transfer via a plurality of links while preventing multiple reception of packets and broadcast stream in a normal state where no failure has occurred. The packet ring network system includes a first packet ring and a second packet ring, each packet ring having a plurality of inter-ring connecting nodes, and each of the plurality of inter-ring connecting nodes in the first packet ring is connected with each of the plurality of inter-ring connecting nodes in the second packet ring in a one to one relationship so that the packet rings are connected with each other. When one of the inter-ring connecting nodes receives a packet to be broadcasted via a link connecting the first and second packet rings the node performs bidirectional flooding of the broadcast packet such that the packet arrives at a predetermined cleave point, and the node uses the source address of the other node so as to falsify the source.

摘要： A communication system includes a server and a plurality of terminals. The server repeatedly assigns transmission periods to the terminals in a regular order, each of the terminals being permitted as a current terminal to transmit data stored in a buffer thereof to the server during an assigned transmission period assigned thereto by the server as a current transmission period. The communication system includes: a transmission controller provided in each of the terminals for transmitting a release request notification to the server in a case where the terminal finishes data transmission before the end of the assigned transmission period assigned to the terminal, and a transmission period assigning portion provided in the server for assigning a next transmission period following the current transmission period to a next terminal different from the current terminal, in response to the release request notification.

The terminal case is formed with a partition wall by which the interior of the case is divided into inside and outside bore parts which are respectively exposed to the interior of the transmission and the outside of the transmission. The partition wall is formed with a plurality of apertures through which electric wires extend. Each of the electric wires within the outside bore part is provided with an enlarged stopper member whose size is larger than that of the corresponding aperture of the partition wall. A plastic adhesive is packed in the outside bore part in a manner to surround all the stopper members.
