基於點對點傳輸技術共通性改善區域網路擁塞之研究
A study of improving the local area network congestion base on common of P2P techniques
摘要
由於現今網路應用多半為線上串流影音的傳輸，以及熱門音樂或是電影的檔案上下載居多，導致許多的網路應用程式多以P2P模式為主體，接著面對的就是P2P傳輸特性所帶來的衍生問題；本論文以P2P為研究對象，一方面基於網路使用，多以P2P傳輸為主，另一方面，基於P2P產生封包現象而對其它網路使用者造成困惱，提出解決方案。並說明P2P軟體傳輸特性造成區域網路擁塞。針對其特性，說明越多用戶端加入越能加速檔案的傳輸，而這樣的特性往往又導致區域網路與廣域網路上充斥著P2P軟體所產生的封包現象，大量佔用網路頻寬，造成區域網路擁塞。 本文將針對區域網路擁塞狀況，提出解決之道。說明透過P2P軟體共同的相關特性，訂定一連串的相關對應規則：一為使用預設連接埠過濾、二為封包特徵值過濾、三為連線數量控管、四為整體流量控管。提出此四項解決方式，做出效果最佳的組合，以降低P2P軟體對區域網路的影響至最小程度，並排除網路服務連線品質的疑慮，讓網路頻寬與網路服務發揮最大功用。

The networking transmission is mostly bound to the Peer-to-Peer (P2P) technique that P2P feature is to accelerate the transmission as quick as more clients added which causes the bandwidth of LAN/ WAN is fully stuffed by the P2P packets. Once the LAN seriously jammed, the users’ ability to connection are interrupted whether how big the bandwidth is. That is, the connection failed from the LAN and is interfered by the packets that switching and colliding. This research aims to solve the jam-packed LAN and to analyze the P2P features by establishing the most affective rules as follows using the Default Port Solution, L7 Filter Solution, Session Limit Solution, and Flow Control Solution—that the four suitable ways are expected to reduce the P2P influence on LAN to minimum and then to clarify the troubles in connecting; and eventually, to exalt the network bandwidth and service in its own quantity and quality function
