| 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.
