Haptic virtual environment performance over policy-based IP networks: a case study

This paper reports on the performance of distributed haptic virtual environment (DHVE) applications deployed over policy-based IP networks. Our previous work reported that a best effort service in IP networks is inadequate for satisfying the quality of service (QoS) requirements of such applications. The current work tries to find out whether applying differentiated services (DiffServ) satisfies DHVE QoS requirements or at least improves them. This work also determines which policies should be applied on the network. A set of experiments was conducted over a network connecting two departments of the Queen's University of Belfast. The results are presented in this paper and compared with our previous work results.
