    • 本論提出以Virtual file為多檔下載的基礎，並以(1) 鄰居的選擇、(2) Choke的選擇、(3) Piece的選擇等三個方向為主軸來解決此不公平現象，同時有效降低Completion Time。
    本論文以模擬器為實驗基礎，分析比較BT的多檔下載方式，並深入探討在其協定中發生不公平的主要情況，研究其在同質、異質網路上的各種效果與影響。

    We investigate the utility of a number of mechanisms to improve the fairness and efficiency of BitTorrent . We make two contributions. First, the effectiveness of a number of Multi-File mechanisms is compared. Second, We show that our proposed strategy can improve the fairness and completion time performance in flash-crowd、Homogeneous and Heterogeneous scenarios.
