點對點計算

網際網路的普及，除了擴大資訊的傳播外，也增進了人類彼此之間的溝通與分享，已對人類文明發展產生了巨大的影響。傳統網際網路的應用，多以主從架構(client-server)來開發系統，而點對點計算(Peer-to-Peer, P2P)則是新興的網路應用模式，各網路節點能同時扮演用戶端、伺服端或中繼者等多重角色，因此比傳統的應用模式更具多樣性。這幾年來P2P的相關應用都大受歡迎，相關技術也被廣泛應用在主幹架構或企業內部網路系統中。有鑑於此，我們規劃「點對點計算」課程，期能透過課堂學習、分組討論與專題實作，增進學生對於新興點對點網路方面所需具備的技術與能力，並培訓具創新、整合能力的網路應用與服務研發人才。課程兼顧理論基礎及實務應用，並透過資源網站推廣優良教材，以期縮短產學供需的落差、擴大人才培訓成效，並彌補產業人才不足。
