Measurement and emulation of time varying packet delay with applications to networked haptic virtual environments

ABSTRACT

Networked haptic virtual environments (NHVEs) are increasingly being used in medical simulation, aircraft maintenance training, and other similar fields. In this paper we present the implementation of a network emulator that can create realistic Internet-like characteristics in a laboratory setting for networked haptics. We compare the quality of this delay emulator to actual measurements taken on the Internet by reflecting UDP data packets and analyzing their round-trip delay distribution and packet loss.
