碩士 === 國立成功大學 === 電腦與通信工程研究所 === 98 === This thesis proposes a Delay-Constrained Scheme for supporting the triple-play services in EPON networks. The proposed scheme adopts a fixed frame approach. In each frame, a mechanism is provided to enable real-time traffic to reserve sufficient bandwidth and control the delay variation to meet its transmission needs. In this manner, the proposed scheme can provide the necessary requirements, such as the guaranteed of the delay variation and delay bound for real-time traffic. Additionally, because the proposed scheme reserve the minimum bandwidth for the BE traffic, the BE traffic can be prevent from starvation. Furthermore, the proposed scheme can dynamically adjust transmission boundary between the real-time and the BE traffic according to the various requests of the subscribers. Finally, computer simulations have shown that the proposed scheme can have better performance than other QoS schemes in terms of throughput, jitter and delay bound.
