| Abstract(in English) | Recently, since the Internet spreads rapidly and widely with high-speed backbone networks, Networked Virtual Environments (Net-VEs), where user can share a virtual space and interact with each other, become popular. Net-VEs deployed over the Internet, generally adopt a client-server architecture and each client transmit a user's action to a server asynchronously. Moreover, most of Net-VEs provides multiple servers for users from the viewpoint of the scalability of the number of users. As the requirements for Net-VEs, we can consider the consistency of a virtual space among users and the responsiveness and fairness to user's actions, especially competitive events. If each server in Net-VEs processes user's actions in order of reception, unfairness will arise although responsiveness can be provided. Moreover, inconsistency among servers may occur. On the other hand, if a server waits for user's action long time enough, responsiveness will be lost, although fairness can be guaranteed. In this paper, we discuss synchronization issues on Net-VEs and propose a new synchronization method among servers, which can guarantee the consistency of a virtual space and provide the responsiveness and fairness to user's actions. |
