乙太被動式光纖網路(Ethernet Passive Optical Network, EPON)的光纖到府技術是目前最受歡迎的接取網路架構，其提供1Gbps高傳輸速率、20公里的遠距離傳輸及具有低成本的佈建費用，因此乙太被動式光纖網路逐漸成為一種可靠且具有成本效益的接取網路架構。網際網路協定電視(Internet Protocol TV, IPTV)又被視為下一代殺手級應用服務，但是IPTV服務與一般網路資料傳輸有著很大不同要求，如對於頻寬、群播技術、服務品質保證有著極高的需求，因此在接取網路方面非常適合使用EPON來傳輸。
雖然乙太被動式光纖網路具有高傳輸速率，但是接取網路的傳輸速度依然低於核心網路(Core Network)，當大量高頻寬需求的IPTV服務從核心網路進入接取網路時，所傳送的要求頻寬超出系統所能負荷的流量，勢必會導致串流影音資料(Streaming video content)傳輸在光纖網路終端發生網路擁塞(Congestion)現象，進而導致封包遺失或者延遲的問題發生，影響使用者觀看的畫面破損及觀看IPTV服務的服務經驗 (Quality of Experience, QoE)。
本論文針對在EPON中運行IPTV中提出了一套最大化觀眾人數允入控制(Viewer-Maximized Admission Control, VMAC)，目的為避免IPTV服務允入連線不當，透過頻道要求資訊來估測各個頻道熱門機率分佈，其優先允入較多人所觀看的頻道連線要求，能夠有效利用頻寬並且最大化使用IPTV服務的人數。此外，由於使用者對於觀看IPTV的品質需求不盡相同，因此本論文根據使用者對於服務品質(如高品質電視、標準品質電視)的需求提供差異化服務，以滿足不同使用者對服務品質(Quality of Service, QoS )的要求，透過調節頻寬分配的策略來保證不會過度分配頻寬。
從模擬結果中顯示，本研究提出的允入控制比先來到先服務允入控制(FCFS-AC)還要高的允入率；並且透過模擬真實環境中使用者要求頻道的行為及人數，觀察出本研究的允入控制與FCFS-AC相比仍然有較高允入人數。

Ethernet Passive Optical Network (EPON) is one of the most popular access network architectures. Because it provides high bandwidth 1Gbps, 20 km long-distance transmission and low-cost provisioning, the EPON has become reliable and cost-effective optical access network architecture. Internet Protocol Television (IPTV) has been seen as the next generation of “killer applications”. IPTV services and data transmission have different requirements in areas such as bandwidth and multicast technology, and there is a high demand for guaranteed quality of service. Therefore, EPON is very suitable for use in an access network.
Although EPON has a high transmission speed, access network transmission speed is still less than the core network, and when a large number of high bandwidth services incorporate from the core network into the access network, this situation will cause the overall bandwidth requirements to be beyond what the system can load. Streaming video content in times of network congestion lead to packet loss and delay, and this can have an effect on the perceived quality of video for viewers.
In this thesis, we propose a Viewer-Maximized Admission Control (VMAC) for integrated IPTV service over EPON. The purpose of admission control is to avoid the IPTV service improperly allowing incoming connections, resulting in over-allocated bandwidth that affects the perceived quality of video for viewers.
Simulation results show that the admission control mechanism we propose is higher than that of an FCFS-AC strategy with regard to admission rate. We also validate our channel popularity model using real user channel access data from IPTV systems and can observe that the number of viewers allowed in a VMAC is still higher than that of an FCFS-AC strategy.
