Abstract

Extended reality (XR) applications require computationally demanding functionalities with low end-to-end latency and high throughput. To enable XR on commodity devices, a number of distributed systems solutions enable offloading of XR workloads on remote servers. However, they make a priori decisions regarding the offloaded functionalities based on assumptions about operating factors, and their benefits are restricted to specific deployment contexts. To realize the benefits of offloading in various distributed environments, we present a distributed stream processing system, FleXR, which is specialized for real-time and interactive workloads and enables flexible distributions of XR functionalities. In building FleXR, we identified and resolved several issues of presenting XR functionalities as distributed pipelines. FleXR provides a framework for flexible distribution of XR pipelines while streamlining development and deployment phases. We evaluate FleXR with three XR use cases in four different distribution scenarios. In the results, the best-case distribution scenario shows up to 50% less end-to-end latency and 3.9x pipeline throughput compared to alternatives.
FleXR:一个实现灵活分布式扩展现实的系统
扩展现实(XR)应用程序需要具有低端到端延迟和高吞吐量的计算要求很高的功能。为了在商用设备上启用XR,许多分布式系统解决方案支持在远程服务器上卸载XR工作负载。然而,它们基于对操作因素的假设,对卸载的功能做出先验的决定,并且它们的好处仅限于特定的部署上下文。为了在各种分布式环境中实现卸载的好处,我们提出了一个分布式流处理系统FleXR,它专门用于实时和交互式工作负载,并支持灵活的XR功能分布。在构建FleXR的过程中,我们发现并解决了将XR功能呈现为分布式管道的几个问题。FleXR为XR管道的灵活分布提供了一个框架,同时简化了开发和部署阶段。我们在四种不同的发行场景中用三个XR用例来评估FleXR。在结果中,与备选方案相比,最佳情况下的分发方案最多可减少50%的端到端延迟和3.9倍的管道吞吐量。
