本文提出了以支援率為基準的串流伺服器選擇演算法，支援率的定義是伺服器端可以提供的上傳頻寬。除此之外，本文也同時比較了此演算法與隨機選擇演算法以及單循環(Round-Robin)排程演算法間的阻塞機率，伺服器負載量，滿載伺服器的個數。由比較的圖表中可以發現，以支援率為基準的串流伺服器選擇演算法的確擁有較低的阻塞機率。有限於一般客戶端的網路流量，當有很多客戶端要收看串流節目時，這時推薦能力比較強的伺服器就變的非常的重要。若是沒有推薦較優良的伺服器，就有可能會造成某些伺服器的負擔大，有些負擔小，造成負載不平衡。客戶端的串流品質也受到影響。

The paper proposed Offered Rate Based Streaming Server Selection Algorithm. The definition of Offered Rate based on the bandwidth which server peer is willing to supply. In the lecture, we show the difference between Offered Rate Based algorithm, Random Selection, and Round-Robin algorithm on blocking probability, server loading, blocking node number. Finally, we show that our algorithm have better performance exactly. According to the capability of client, when there are huge amount of crow want to watch program, server selection become very important. If you don’t implement load balance strategy, the watching quality will be low.
