| Summary: | 碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 98 === The evolution of technologies in access network are expediting much quicker in the recent year, such as Digital Subscriber Line (DSL), Wireless Network (WiFi and WiMAX), Cable Network (Hybrid Fiber Coaxial, HFC) and Ethernet Passive Optical Network (EPON). The downlink/uplink bandwidth increase dramatically. Thus more and more bandwidth-intensive applications are emerging, such as Voice over IP (VoIP), video conferencing, interactive gaming and IPTV (Internet Protocol Television, IPTV).
In the access technologies mentioned above, Ethernet Passive Optical Network (EPON) with high speed downlink bandwidth is suitable for carrying Internet Protocol Television (IPTV) service. Many papers had proposed some multicast mechanisms to make EPON carry IPTV real. However, without an effective admission control to determine which IPTV channel requests from users can enter the EPON, the high bandwidth demand of IPTV service will paralyze the EPON. In this thesis, we propose a popular channel first (PCF) admission control (AC) algorithm for deploying IPTV service over EPON. Finally, simulation results show that our propose algorithm can improve the bandwidth utilization (more scalable) and can satisfy more IPTV channel requests.
