Scalable distributed virtual environments using multicast application level

Most of architectures proposed for developing distributed virtual environment (DVE) allow limited number of users. To support the development of applications using the Internet infrastructure, with hundred or, perhaps, thousands users logged simultaneously on DVE, several techniques for managing resources, such as bandwidth and capability of processing, must be implemented. The strategy presented in this paper combines methods to attain the scalability required, in special the multicast protocol at application level.
