<p>PURPOSE:To attain efficient multiple address communication even if the reply from anode shows unsuccessful reception by applying message transmission to a downstream node of its own node and multiple address for the transmittal confirmation. CONSTITUTION:A node A sends a MSG1 to nodes B, D at a time t0. The node B returns an ACK1 to the node A ht times t1, t2 and the MSG1 is received by its own node and the MSG1 is sent to nodes C, G. In case of the node D, similar processing is applied to receive the MSG1 by its own node and the MSG1 is sent to nodes E, F. Thus, each node transmits the message to the adjacent downstream node in the communication tree, and applies the transmittal confirmation to attain multiple address and even if the reception of the reply from a node is not successful, all nodes are not awaited.</p> |
