Volumetric streaming in private 5G network
收藏资源简介：
Overview=========This dataset contains logs from consumer and producer applications of the volumetric streaming application that was developed during the AVID-NMP project [1]. The source code of the application is available at [2]. The logs were collected by experimenting over a private standalone 5G network. The experiment included 2 video producers, 1 video consumer and an SFU/MCU; the latter was deployed in 5G MEC, while the users were deployed in the 5G RAN. Three different experiment setups were investigated: P2P mode, where producers stream data directly to the consumer; SFU mode, where the producers send the video stream to the SFU/MCU which simply forwarded it to the consumer; and MCU mode, where the producers sent the video stream to the SFU/MCU which transcoded it to JPG stream and then forwarded it to the consumer. Each setup is explored with one and two producers acting simultaneously. With MCU, four different quality levels for JPG frame encoding are explored (25, 50, 75 and 90). For further details, refer to the README.txt file. =========References========= [1] AVID-NMP Project site: https://mmlab-aueb.github.io/avid-nmp/[2] Volumetric streaming application repository: https://github.com/mmlab-aueb/nmp/tree/master/volumetric_streaming_app
数据集概述========= 本数据集包含AVID-NMP项目[1]中开发的体积流式传输应用的生产者端与消费者端程序日志。 该应用的源代码可通过[2]获取。 本次日志通过私有独立5G网络上开展的实验采集得到。实验涉及2台视频生产者、1台视频消费者以及1台选择性转发单元/多点控制单元（Selective Forwarding Unit/Multipoint Control Unit, SFU/MCU）：其中SFU/MCU部署于5G多接入边缘计算（5G Multi-Access Edge Computing, 5G MEC）环境，用户终端则部署于5G无线接入网（5G Radio Access Network, 5G RAN）中。 本次研究共考察3种不同的实验配置：点对点（Peer-to-Peer, P2P）模式，即生产者直接向消费者推送数据流；SFU模式，即生产者将视频流发送至SFU/MCU，由其直接转发至消费者；以及MCU模式，即生产者将视频流发送至SFU/MCU，由其转码为JPG（Joint Photographic Experts Group）流后再转发至消费者。 每种配置均分别采用1台及2台生产者同时运行的场景进行测试。在MCU模式下，还针对JPG帧编码设置了25、50、75、90共4种不同质量等级开展测试。 如需了解更多细节，请参阅README.txt文件。 =========参考文献========= [1] AVID-NMP项目官网：https://mmlab-aueb.github.io/avid-nmp/ [2] 体积流式传输应用程序代码仓库：https://github.com/mmlab-aueb/nmp/tree/master/volumetric_streaming_app
