The recent diffusion of wide area networks dis- tributed applications, like distributed virtual environ- ments (DV Es), for instance massively multiplayer games, requires the definition of proper consistency mod- els and protocols. Models like perceptive consistency take into account the interactivity of these applications by defining a set of real time constraints. This paper presents MultiLags, a protocol implementing perceptive consistency which exploits DV E locality to dynamically refine the time constraints according to the network con- ditions. An implementation of the protocol is presented. A set of experimental results show the effectiveness of the MultiLags approach.
