Abstract

Large Distributed Virtual Environments (DVEs) combine the interactions of many users, constituting a highly complex distributed system that encompasses of a multitude of heterogeneous computers and communication over varying networks. The size of a DVE is not only measured in the spatial reach of its virtual world, but also the number of concurrent users it can provide a sufficient quality service for. The existence of hardware or software failure of these many parts must be considered the normal state of operations for any sufficiently large DVE. We propose QuP, an approach to provide high fault tolerance when compared to many P2P approaches. QuP is also able provide the service of a large DVE service to clients connected via asymmetric or lower bandwidth networks.
