Abstract
Predicted availability of broadband access will enable deployment
of network virtual environments over the Internet. Online virtual worlds
will require efficient runtime data replication solutions. This paper
presents a quality of service (QoS) architecture for just-in-time data
replication in network virtual environments. Quality of service is
achieved by predicting the load and adapting to network traffic
variations. Data is prefetched at the client based on network traffic
estimates and viewpoint navigation prediction. QoS negotiation allows
the server to control the network resources allocated per client.
Experimental results show that QoS data replication can be implemented
with reasonably small network and sever overload
