摘要:
A window‐based token ring protocol supporting two priority traffic streams is proposed. This protocol uses the window timers to limit the packet transmissions of a token holding station. The packets arriving during a window period are always transmitted before those arriving during subsequent window periods. Nonpreemptive priority service discipline is used to serve high priority packets. A call admission control policy based on delay bound is then employed to guarantee QoS such as the packet delay, delay jitter, and the packet loss‐free requirement for both priority traffic streams. Under such window‐based token ring operation and call admission control, network‐wide fairness can be achieved and the network output traffic characteristics become predictable. With these properties, we would expect that the window‐based token protocol is more appropriate for real‐time communications.
