Massive Multiuser Virtual Environments (MMVEs) and especially the idea of a ''3D Web'' as a combination of a MMVE and today's WWW currently attracts a lot of attention. The realization of such a vision on a global scale though poses severe technical challenges to the underlying network infrastructure. It is generally accepted that such a global scale scenario can only be realized in a distributed...
We propose the design of Plug, an application to find and keep contacts with friends within many inter-connected 3D virtual worlds. Users use an instant messenger (IM)-like interface to converse with friends and find new contacts, using a virtual representation of the user's self. It consists of three parts: a plug is an automatous agent / avatar situated at a user's computer that reflects and mimics...
We collected packet traces from second life client sessions and analyzed the packet contents. We observed that textures constitute a majority of the network traffic. We further characterized the textures from three selected regions in second life in terms of their size and spatial distributions. We found that textures in these regions exhibit a different size distribution from files on a file system...
Peer-to-peer (P2P) architectures have recently become a popular design choice to build scalable Networked Virtual Environments (NVEs). While P2P architectures offer better scalability than server-based architectures, efficient distribution and management of avatar and object states remains a highly challenging issue. In this paper, we propose GROUP, a fully-distributed P2P architecture for NVEs that...
