CONCLUSION

With the emergence of “NewSpace” mega-constellations which promises to provide low-latency and high-throughput Internet service globally, this paper studies a futuristic yet important problem: can mega-constellations help to enable lowlatency RTC globally? We propose S PACE RTC, a cooperative framework that judiciously selects communication paths over clouds and satellites to accelerate wide-area online interactions. Comprehensive evaluations driven by real videoconferencing traces show that our cooperative framework can reduce up to 64.9% communication latency for wide-area RTC sessions.

随着有望在全球范围内提供低延迟和高吞吐量互联网服务的“NewSpace”巨型星座的出现，本文研究了一个具有未来性但又重要的问题： 巨型星座能否帮助实现全球低延迟 RTC ？

我们提出了 SPACE RTC，这是一个合作框架，可以明智地选择跨云和卫星的通信路径，以加速广域在线交互。由真实视频会议跟踪驱动的综合评估表明，我们的合作框架可以将广域 RTC 会话的通信延迟降低高达 64.9%。作者已在 https://github.com/SpaceNetLab/SpaceRTC Project 上公开了他们的代码或数据。
