摘要

隨時網際網路的普及，數位家庭將是未來值得大家探討的一個議題。在數位家庭網路中，許多消費型電子產品廣泛使用通用型隨插即用協定，不同品牌的設備不需要多餘的設定，即可互相運作使用，讓使用者透過有線或無線的傳輸方式來播放電腦中的檔案。通用型隨插即用協定設備以廣播封包通知它們的服務，在路由器不提供轉送廣播封包的情況下，通用型隨插即用協定只能在區域網路環境使用。本篇論文提出通用型隨插即用協定跨網際網路分享，通用型隨插即用設備可以透過伺服器建立一個虛擬區域網路，由於資訊安全的需求，可以限制資源僅能分享給同一個虛擬區域網路，接著實作這個概念，從實驗結果可以看到封包的耗費時間幾乎沒有增加，本篇論文提出一種可行的檔案分享方式。

As the Internet becomes a part of people's lives, digital home networking becomes important research topic in the future. In digital home networking, many consumer electronics use UPnP protocol. Even though they are products of different manufactures, they can auto-configure and co-operate with each other. For example, a user can use any media player to play media files from media servers in wired or wireless networks.UPnP devices advertise their services by multicasting UPnP messages. Because the current routers do not route any multicast datagram, UPnP multicast messages are broadcast only within a local area network. In this thesis, the topic of UPnP resource sharing over the Internet is studied. Due to the security requirement, many UPnP devices can logically connect as a virtual LAN by VLAN server, but UPnP devices of different VLANs will not share their resources with each other. The concept was implemented and experimental results show that the proposed method will add little overhead such that the proposed method can be considered to be an alternative to this research topic.
