Scalability for Virtual Worlds

In this paper, we propose a distributed model for massive scalability in net-VEs. Our model inherits concepts from distributed databases, where the application logic and transaction processing take place at the client machine. The key feature of our model is its novel transaction model, which exploits application semantics to reduce the number of messages needed to maintain consistency. Our proposed model imposes no major restrictions on the interaction between participants located in different parts of the world, and so can be easily adapted to a wide range of net-VEs.
