Abstract:	近年來，同儕運算(Peer-to-Peer, 簡稱P2P)的應用越來越廣泛，而許多採用P2P的軟體也相繼出現，供人使用，然而建構一個P2P的網路虛擬環境(Networked Virtual Environment，簡稱NVE)仍有許多問題需要解決，例如：事件一致性(Event Consistent)、反應性(Responsibility)、安全性(Security)、擴展性(Scalability)、容錯性 (Reliability)，其中事件一致性又可分為因果關係一致性(Causal Consistent)跟順序一致性(Sequential Consistent)。在順序一致性中，多個使用者在爭奪一個資源時，資源的歸屬及使用者獲得相同的資訊是一個重要的課題。因此本論文將提出一個建構在P2P NVE的資訊交換機制，目的是透過此一資訊交換機制，讓使用者在爭奪資源時，獲得相同的資訊，解決順序一致性的問題。根據上述目標，本論文提出的資訊交換機制使用了ACK以及優先權(Priority)的概念，確保所有人都收到相同的資訊。 In recently, there are many applications in a Peer-to-Peer environment. There are many problems in P2P Networked Virtual Environment such as event consistency、responsiveness、security、scalability、reliability. Event consistency was divided two problems such as causal and sequential consistency. In sequential consistency, when many avatars are competing a resources, who can get the resource, and avatars receive the same information are very important. This thesis proposes an Information Exchange Mechanism to make sure that avatars received the same information, when avatars are competing a resource in a P2P NVE. The ACK and Priority mechanisms are proposed to solve this problem.
