This paper presents DiV ES, a distributed support for the development of networked Distributed Virtual Environments. DiV ES exploits the publish subscribe interaction model to deﬁne a ﬂexible communication support. An acyclic peer to peer network of brokers has been deﬁned to support an event based communication framework. The network can be dynamically reconﬁgured and it can tolerate broker crashes by a proper recovery mechanism. A set of optimization strategies of the basic publish/subscribe routing mechanism has been deﬁned through an accurate analysis of the information exchanged in DV E applications. The message trafﬁc on the network is reduced by packing notiﬁ- cations and ﬁlters into a single message. Furthermore, approximated ﬁlters are introduced to further reduce message trafﬁc. Advertisement are exploited to optimize the routing of ﬁlters.
