Method for reducing collisions, latency and latency jitter in a network by maintaining a contention-resolution derived queue ordering

摘要

A network interface examines a field of a successfully transmitted frame following a contention resolution and transmission ordering among a plurality of nodes contending for transmission of a frame. The field indicates whether the successfully transmitting node has any additional frames to transmit. The number of backoff slots is maintained at a current value, rather than decremented, if the field indicates that the successfully transmitting node has an additional frame to transmit. The next frame to be transmitted is assigned the highest backoff slot. This procedure avoids re-contention and re-ordering when the contending nodes have additional frames to transmit, thereby improving overall network performance.
