近年來由於 P2P (Peer-to-Peer)技術發展十分迅速,越來越多人仰賴在網路上分享資源,為了因應使用者人數增多的問題,目前大部分 P2P 的研究多著重在節點的延展性和查詢效率,來解決節點數量增加與搜尋速度的問題。隨著資訊科技的進步,越來越多的資訊都放在網路上,分享資源的種類也越來越複雜,例如分享的資源有可能是檔案(文字檔、音樂檔、多媒體影音檔)、 CPU 的計算能力、印表機的列印能力等等。可以預期的發展將會類似 World Wide Web 的情形,以後要找的資源不是太少,而是太多,而這類的研究以關鍵字作搜尋,搜尋結果大多不是使用者所需要的資源,導致資源搜尋結果的正確性降低,找不到存在的資源或是找到錯誤的資源,都會使得搜尋的結果無法滿足使用者的需求。因此本研究使用語意中的資源描述架構 Resource Description Framework, RDF)來描述資源,將資源作分類,結合新的 P2P 網路架構,來提升搜尋資源的正確性、搜尋速度和延展性。
In recent years, due to the emerging of P2P technology. People rely on the Internet to share resources. To resolve the increasing number of users problem, many researches had been devoted to focus the scability and efficiency of P2P routing protocols. With a view to resolve the increase of the number of nodes and the search efficiency problems. With the advancement in information technology, more and more information is already on the Internet. The diversity of shared resources is high increasingly. For example, the shared resources may be files (text, music or multimedia), CPU sharing, printer, and so on. It can be envisaged that the development will be similar to the World Wide Web in that the resources will be flourished over the Internet. Most currently resource discovery is through the keyword a search. Search results usually fail to meet user''s need. They either could not find the appropriate resources or find the undesired resources. The results of the search can not meet the demand of users. In this research, we use of semantic RDF(Resource Description Framework) to describe resources, the resources are classified according to the new peer-to-peer network topology architecture. The newly proposed system provides correctness, efficiency and high availability.
