    Abstract: 隨著寬頻Internet網路的普及電腦硬碟容量的大幅提升,網路用戶很自然地藉由高效率的分散式P2P檔案軟體與廣大的網路用戶並行地交換他們喜愛,受到著作權保護的整張VCD或DVD的影片或歌曲,致造成Internet訊務的嚴重失衡:少數P2P用戶的訊務耗盡連線頻寬,影響大部分使用者的權益,及帶來頻繁的網路著作侵權抱怨。本研究實做以封包內含為基礎的P2P訊務監測系統,運用switch router的monitor功能,監聽網路主幹轉送的封包內容,追蹤明顯的BitTorrent, GUNTELLA, eMule/eDonkey P2P應用的多項特徵,統計Top-N P2P大戶的訊務量及辨識其使用的應用軟體。該系統已成功地架設於TANet區網中心,協助管理者監看/發現P2P大戶的主機IP, port number,使用的P2P種類甚至制定適當管理策略,適度限頻超量的P2P傳訊流,維持網路運作效能及改善著作侵權的問題。
    P2P technology not only removes central control of such resources as communication, computation, file storage and retrieval, current P2P applications also have the ability to use arbitrary ports to camouflage their existence. The participants in the system thus could easily hide personal identifying information easily. As most of the P2P traffic can not be classified by simply looking at the IP packet headers, and the deep inspection of packet payload of layer-7 patterns was usually employed for P2P traffic measurement. This work makes use of the packet payload snooped from a Gigabit Ethernet link over the backbone router to develop P2P traffic measurement that measures and identify the P2P traffic according to the signaling word of the prevalent P2P applications. The system has been deployed in one regional network center over a TANet network center for assisting network users grasping the Top-N P2P delivering hosts and the P2P application they used.
