IPC: H04L12/417
Filed: 1984-05-21
Abstract: PURPOSE:To improve the reliability of data transmission by transmitting a reception confirming response at the reception of multiple address communication information to the same group while a communication medium is subjected to time division to prevent collision between other transmitters (nodes) and a response thereby attaining the reception confirmation response at group multiple address communication. CONSTITUTION:A transmission node generates a group list informing instruction (SGL) in Fig. B in each node and transmits it to a transmission line 1. A reception-side node receives the SGL instruction and the node designated by a node address list based on its information writes various information into a RAM26. When group multiple address communication data of the group address designated by the received SGL instruction is received as a destination address successively, each node receiving the data transmits a response to the transmission node after awaiting that a prescribed guarantee time Tx is elapsed. The guarantee time Tx depends on each nodes and is represented by Tx=(n-1)XTs, where (n) is the location of the next node address in a group constituting list counted from the start location and Ts is a prescribed time slot time larger than the processing time of response.
