Abstract:

Virtual Reality (VR) is an important scenario in the future 6G era, but traditional traffic models can no longer accurately describe the characteristics of VR. In this paper, a measurement-based study is reported for data collection and analysis of VR. Considering the differences between different types of VR traffic, we choose VR 3D panoramic video and VR online game for the research of basic traffic characteristics and traffic modeling. Basic traffic characteristics include the data rate, probability distribution of the packet length and packet interval for both uplink and downlink. In addition, a generalized deterministic arrival curve modeling scheme is proposed based on the cumulative arrival process and network calculus, and the parameter values of the arrival curve are deduced based on the measured data.

Key words: virtual reality, network calculus, arrival curve, measurement
