Distributed Virtual Environments (DVE) allow multiple users to interact with virtual worlds sharing and handling objects in real time. The development of large scale DVE deals with constraints imposed by communication system. On a former work, the approach implemented in AVDNet helps on reducing the amount of package on communication network and on reducing computational process to render virtual environment by creating regions that separates spatially the environment. However, it has restrictions on dealing with bandwidth management and on choosing suitable servers, considering the servers availability. In this paper we present the AnyAVDNet: a framework that implements dynamic load distribution among servers of virtual environment regions using anycast application level protocol. Also, we show a metric implemented to support choosing of server considering both resources available (processor and memory), and communication resources (bandwidth and trace route) for each server connected.
