Abstract

A MAC scheme of HORNET based on PRI and node structure with variable optical buffer is reported. When collision is detected in an AP, PRI of this coming packet is compared with that of the packet being transmitted, if priority of the former is low, it will be routed into a variable optical buffer to loop for the latter. If its priority is high, the buffer will be closed, and the coming packet will be transmitted undisturbedly. On the other hand, the packet being transmitted is terminated, and the transmitter sends out a jamming signal. The downstream AP recognizes the incomplete packet by the presence of the jamming signal and pulls it off the ring. The AP can reschedule the transmission of the packet for a later time. Thus it can be ensured that the packet with high PRI will be transmitted first when conflict emerges.
