基于多网络接口的高性能虚拟现实服务
High-performance virtual reality service based on multiple network interfaces
近年来硬件技术和第三代高速千兆WiFi解决方案的进步,为互联网吞吐量的显著提升铺平了道路,从而使得虚拟现实（VR）和增强现实（AR）等更复杂的应用成为可能。本文探讨了VR直播这一新兴领域,该领域将VR与直播技术相结合,为用户提供具有全景视角和3D显示的高度沉浸式观看体验。尽管VR直播在增长,但它面临着重大挑战,尤其是视频拼接和编码的高计算需求。传统方法依赖本地资源,但这些资源往往不足。云计算的出现提供了一个有前景的解决方案,通过将计算密集型任务外包到云端,从而减轻本地系统的负载。本研究引入了一种新机制,在采集终端使用多网络接口控制器来提高带宽利用率,并确保多摄像头视频流的同步到达以进行有效拼接。研究提出了一种多路径传输模型,旨在管理潜在的网络拥塞并优化云端的缓冲队列长度,从而改进采集终端的路由策略。通过大量仿真和原型系统实验,该方法的有效性得到验证,显示出优于现有方法的资源效率和性能。本文不仅解决了技术挑战,还为VR直播的可扩展性和服务质量做出了贡献。

Recent advancements in hardware technology and high-speed Gigabit WiFi solutions have paved the way for significant enhancements in Internet throughput, thereby enabling more sophisticated applications such as virtual reality (VR) and augmented reality (AR). This paper explores the burgeoning domain of VR live broadcasting, which merges VR with live broadcast technology to offer users a deeply immersive viewing experience featuring panoramic views and 3D displays. Despite the growth, VR live broadcasting faces substantial challenges, notably the high computational demand for video stitching and encoding. Traditional methods rely on local resources, which are often insufficient. The advent of cloud computing offers a promising solution by outsourcing compute-intensive tasks to the cloud, thus alleviating the load on local systems. This study introduces a novel mechanism that employs a multi-network interface controller at the acquisition terminals to enhance bandwidth utilization and ensure the synchronous arrival of multi-camera feeds for effective stitching. We propose a multi-path transmission model designed to manage potential network congestion and optimize buffer queue lengths in the cloud, thereby improving routing strategies across acquisition terminals. Our approach is validated through extensive simulations and prototype system experiments, demonstrating superior resource efficiency and performance over existing methods. This paper not only addresses technical challenges but also contributes to the scalability and quality of service in VR live broadcasting.
