    Abstract: 隨著資訊家電的興起,寬頻網路的普及,數位家庭已是未來的趨勢。隨著近年來家電數位化的趨勢,家庭網路已逐漸成為一個非常熱門的議題,其中由微軟所推動的UPnP(Universal Plug and Play)是由加入UPnP Forum多家廠商共同制定出的家庭網路介面標準。透過這個開放性平台,家庭網路中的智慧型家電、個人電腦以及各項相關服務,都可以互相分享資源,不需經過設定、省去複雜的安裝程序,彼此互相溝通。由於UPnP是種分散式、開放式的網路架構,由所用的通訊協定所定義,因此不受任何特定作業系統、程式設計語言、或者實體媒體的影響。 而在UPnP AV網路中多媒體檔案要做分享多半採串流(Streaming)的方式做檔案傳輸。而在頻寬寶貴以及檔案傳輸趨於複雜的環境下,如何讓頻寬有效的調整達到系統效能的提升成為一個課題。我們以此為出發點,提出我們的頻寬分配的演算法,藉由區分環境中兩種不同優先權等級的Session比較,期望能讓高優先權的Session能達到較佳的效能。此外,並對當有Session傳送完畢釋放出來的頻寬是否要作處理分別去討論比較。最後用程式模擬分析我們的結果。並且由結果可看出我們所提出的方法對於高優先權的效能都會優於低優先權的Session,而且在釋放出來頻寬有做處理上對於同等級的Session其效能會比沒有做處理的來的佳。 With the prosperity of information home appliances and the popularity of broadband networks, digital family is sure to be a leading trend in the upcoming future, and it is considered as a bullish area by the industry. Because of the rapid development of the digital home appliances in recent years, the domestic home network also drags more and more attention. The UPnP(Universal Plug and Play) propelled by Microsoft came up with the standard of home network’s protocol by UPnP Forum, all the smart home appliances, personal computers and other related services are able to share information through this platform without any complex setup procedure. In UPnP networks, we use streaming for transferring AV Media files. But in review relate research papers, we hardly to find a bandwidth allocate algorithm for the home networks. We think home network’s surroundings will be more and more complexity in the future. So in our paper, we propose a suitable bandwidth allocating algorithm in our system. Finally, in the software simulation, we compare two bandwidth allocating methods and we adjust the system parameters to get the results. The results of our simulation show that different priority’s performance is different. One of our methods its bandwidth is more useful than the other.
