ABSTRACT:
Collision delay intervals are modified in Ethernet network devices by transmitting priority data requiring a guaranteed latency by determining an integer multiple number of slot times, randomly selected from a predetermined range of integers, where the range of integers is independent from the number of access attempts. A network device having priority data for transmission randomly selects a collision delay interval to be either zero or one slot time for a predetermined number of access attempts. If the number of collisions encountered by the network station exceeds the predetermined number, the integer is selected from a range of integers calculated from a shifted exponential number of the access attempts, resulting in a smaller range than used for normal priority traffic. Use of the collision mediation for high priority traffic on a half-duplex Ethernet network provides a bounded access latency for real-time and multimedia applications by granting the network device a higher probability of successfully accessing the network media.
