Dataset from VR Streaming Server (Emulated) and Radio Access Network for Streaming Traffic

The dataset contains an experiment in a site where UEs attach to a gNodeB that provides access to a streaming server that is stressed with high demanding transcoding workloads to emulate VR/AR processes. The UEs are realized through the Remote UE mode enabled by Amarisoft Simbox emulator, and the gNodeB is realized through the Amarisoft Callbox, which also provides the user plane function. The emulated VR streaming server is deployed as a Nginx pod in a Kubernetes cluster. We rely on MonB5G sampling functions that feed monitoring data (CPU and RAN parameters) to the monitoring system. A streaming video server has been deployed with the help of a NGINX server. It provides video-on-demand and video streaming, which can be accessed by any user (or UE) for real-time reproduction. This VR video streaming emulation aids to assess the performance of the network and therefore the benefits that each solution has brought. The video “Big Buck Bunny” with h.264 encoding and a resolution of 1920x1080p has been used for the experiments. The description of dataset features are: 1-) Index Number, 2-) Time: Time of the experiment, 3-) N: number of VR streaming clients, 4-) R: Instantaneous downlink bit rate [Mbps], 5-) C: Average CPU of VR streaming server [mc] The original video file information: Video codec Advanced Video Codec (AVC) Width 1920 pixels Height 1080 pixels Display aspect radio 16:9 Duration 10 min 34 s Max Bitrate 16.7 Mb/s Frame rate 30 FPS

本数据集包含一项在特定站点开展的实验：用户设备（UE, User Equipment）接入向流媒体服务器提供接入服务的gNodeB，该流媒体服务器承载高负载转码工作负载，以模拟VR/AR处理流程。用户设备通过Amarisoft Simbox模拟器启用的远程用户设备（Remote UE）模式实现，而gNodeB则由同时提供用户面功能的Amarisoft Callbox实现。模拟VR流媒体服务器以Nginx Pod的形式部署于Kubernetes集群中。我们依托MonB5G采样功能，将监控数据（CPU及无线接入网（RAN, Radio Access Network）参数）上传至监控系统。此外，我们还借助Nginx服务器部署了一款流媒体视频服务器，其支持视频点播与视频流媒体服务，可供任意用户（或用户设备）进行实时播放。本次VR流媒体仿真实验旨在评估网络性能，进而验证各解决方案所能带来的增益。本次实验采用了经h.264编码、分辨率为1920×1080p的视频《Big Buck Bunny》。
