ABSTRACT
Consistency is a crucial requirement for Massively Multiuser Virtual Environments (MMVEs). Such systems provide virtual worlds in which thousands of users can interact in realtime. To realize a consistent world view for all users, a flexible consistency management is required which balances the responsiveness and the level of consistency in the system. In this paper we present an approach for a consistency management for peer-to-peer-based MMVEs. The approach identifies users which actually interact with each other in the virtual world, groups them in consistency sessions and synchronizes all users in the session according to a synchronization protocol which is determined at runtime. We discuss the concept of consistency sessions, present algorithms to create and maintain sessions, and analyze what features are still missing and must be added in the future.

Peer-to-peer multimedia applications
MM '06: Proceedings of the 14th ACM international conference on MultimediaIn both academia and industry, peer-to-peer (P2P) applications have attracted great attention. Peer-to-peer file sharing applications, such as Napster, Gnutella, Kazaa, BitTorrent, Skype and PPLive, have witnessed tremendous success among end users. And ...
Consistency maintenance in dynamic peer-to-peer overlay networks
Overlay distribution structures and their applicationsIn this paper, we present techniques to maintain temporal consistency of replicated objects in data-centric peer-to-peer overlay applications. We consider both structured and unstructured overlay networks, represented by Chord and Gnutella, respectively,...
Analysis of TTL-Based Consistency in Unstructured Peer-to-Peer Networks
Consistency maintenance is important to the sharing of dynamic contents in peer-to-peer (P2P) networks. The TTL-based mechanism is a natural choice for maintaining freshness in P2P content sharing. This paper investigates TTL-based consistency ...
