PACKET COMMUNICATE TERMINAL

摘要

The present invention discloses a communication terminal included in a network system in which a plurality of communication terminals are connected to a single transmission medium. A priority information acquisition section (11) acquires priority information contained in a currently transmitting packet. A priority determination section (13) determines, based on priority information contained in a to-be-sent packet and the priority information acquired by the priority information acquisition section (11), which one of the to-be-sent packet and the currently transmitting packet should be given priority. A jam signal generation section (14) generates a jam signal if it is determined by the priority determination section (13) that the to-be-sent packet is given priority. A communication section (15) sends out the to-be-sent packet on the transmission medium after the jam signal stops and before the currently transmitting packet is sent out again.
