Abstract
A data transmitting/receiving method using distributed path control in a data switching system is disclosed, including the steps of: (1) storing data by distributing a first code and a last code of a received data frame, and then reading and storing a frame header; requesting a path setting and then initializing a trial number; transmitting a setup request signal in the next time slot with a destination port address if a polling address is its own address, and thus transmitting the stored header through a data channel when the response signal received from the destination output port indicates an end of the path controlling operation; and transmitting data stored in an input buffer to the end of a frame and requesting a path release at its polling address; (2) releasing the path in case of path release request when the destination port address is its own port address; if the output port is not in use, the output buffer is not is a full state, and a communication channel is available, indicating the end of the path controlling operation in a response bus in case of the path setup request and receiving a switch path setup data to discriminate an initial code and last code of the frame, thereby transmitting the data.
