摘要:

虚拟现实(Virtual Reality,VR)是未来6G时代的一个重要应用场景,但由于传统业务模型已无法精准刻画其业务的特征,我们提出了一种基于测量的VR业务数据采集与分析建模方案。考虑到不同VR业务之间的差异性,选取VR 3D全景视频与在线游戏两种业务展开研究,分别分析了上行和下行业务流的基本特征,包括数据速率、数据包长度和包间隔的概率分布等。此外,依托业务流累积到达过程和网络演算理论提出了一种普适的确知到达曲线建模方案,并基于测量数据推导了确知到达曲线的参数取值。

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
