Abstract
A methodology is disclosed for effecting contention-free communication over a plurality of Collision-type lines interconnecting numerous synchronized stations. In broad terms, each station having a message to transmit executes a prescribed encoding/algorithm. Each station also monitors the states of the lines and depending upon the dynamic states of the lines, the lines are associated with prescribed ones of the lines during each bit interval. At any stage of the detection process, if it is determined that a line broadcasts of unique message, then this line is assigned to the station generating the unique message for the remainder of the frame. The remaining lines are then available for reassignment in subsequent bit intervals. The pattern of bits detected at the end of the frame by each of the lines determines successfully transmitted messages.
