    • 本論文中將結合視訊串流伺服器(Video Streaming Server)及我們所發展的動態頻寬管理視訊串流法則(Dynamic Bandwidth Video Streaming Management)，讓視訊串流系統在調節頻寬的時候可以達到以下兩點目標：
    (1) 當總流量超過安全範圍，調節頻寬時可最小化視訊品質之降低。
    (2) 頻寬充足時，調節頻寬且最大化的提昇視訊品質。

    另外，我們撰寫了一個使用本演算法則之視訊串流伺服器模擬程式以及建立了一個使用本演算法的視訊串流伺服器。而本論文將分析比較模擬所獲得的數據及實際運作時所量測到的數據，證明本論文所提出之演算法則是有效的。

    In this thesis, we propose a bandwidth management algorithm and implement a video streaming server with this algorithm. We want the system can achieve two goals as follows:
    (1) When total used bandwidth of video streaming server is over safety area, video streaming server will manage bandwidth and minimize video quality decadence.
    (2) When total used bandwidth of video streaming server is under safety area, video streaming server will manage bandwidth and maximize video quality increase.
    In order to verify this algorithm, we implement a video streaming system simulate program using the algorithm and also implement a positive video streaming system. We will test these two systems in several scenarios and get some measurements. According to those measurements, it can be observed that the algorithm is effective and useful.
