In this paper, we study the link sharing between the assured real-time traffic and the throughput intensive best-effort services. Our simulation shows that the throughput intensive best-effort services can degrade the QoS performance of real-time services if both are forwarded to a single FIFO queue. Therefore, it is advantageous to assign separate queues for individual classes of traffic. A novel link-sharing scheme (delay-sensing) is proposed to improve the QoS measures such as delay and jitter for the real-time traffic while preserving the fairness among different traffic classes. The new method guarantees an explicit delay bound for the real-time traffic when bandwidth borrowing is allowed. Another advantage of the method is that it can offer different priority classes with user specified fairness.
