Abstract:	近年來網路用戶大增，代理/中繼伺服器亦已經廣泛運用在網際網路上，在一般傳統點對點傳送時，伺服器若有大量用戶請求資料時需要較長時間才能一個個處理傳送完所有請求，這樣可能導致請求已經過時，用戶端已經不在需要，且已有新的請求發出，即伺服器無法即時的滿足各用戶，本篇論文則顧慮在廣播環境下之頻寬利用率提出了一種在Ethernet環境下代理/中繼伺服器利用network coding技術來調整傳送次序及編碼資料，並模擬在有大量用戶下，亦能有效提高網路頻寬利用率，使用戶的等待時間減少，並且各用戶之間不需要有所聯繫，只需要與伺服器連結即可。 Recently, the number of internet users increase quickly. The proxy/relay server popularly has being used in the internet. In traditional peer to peer transmission, it needs a long time when server needs to handle a lot of requests from clients. It may cause the requests have being out of time, and clients don't need the data anymore. It means that the server can't give service to all clients immediately .In this paper, we consider the throughput in broadcast environment to propose a method using network coding technique to reschedule the transmission sequences. Our simulation results show that our algorithm can reduce the average waiting time and raise the throughput when server has a lot of clients.
