A networked virtual reality (NVR) is a software plane where multiple users can interact with each other in real time, even though these users may be distributed around the whole network. This project focuses on the design of an efficient transport/network layer service to provide QoS guarantees to an NVR system. We propose to model the NVR source characteristics, the communication patterns between remote sites, and its bandwidth, latency, and reliability requirements of the underlying network layer.
