论文摘要
低地球轨道卫星网络（LSN）已被提倡作为即将到来的6G的真正全球覆盖范围的关键基础设施。本文介绍了我们对Starlink端到端网络特征的初步测量结果和观察结果，这可以说是迄今为止最大的LSN星座。我们的发现证实，LSN是针对地球上无处不在的互联网覆盖范围的有前途的解决方案。但是，我们还发现，与地面网络用户相比，Starlink的用户在吞吐量和延迟中的动态更大，甚至频繁停电。它的用户体验受到环境因素，例如地形，太阳风暴，雨，云和温度的影响，功耗也是如此。我们进一步分析了Starlink当前的弯管中继策略及其限制，尤其是对于跨界路线。我们还探索了其流动性和可移植性潜力，并将我们的实验从城市城市扩展到面临着独特的实际和文化挑战的野生偏远地区。
Low Earth orbit Satellite Networks (LSNs) have been advocated as a key infrastructure for truly global coverage in the forthcoming 6G. This paper presents our initial measurement results and observations on the end-to-end network characteristics of Starlink, arguably the largest LSN constellation to date. Our findings confirm that LSNs are a promising solution towards ubiquitous Internet coverage over the Earth; yet, we also find that the users of Starlink experience much more dynamics in throughput and latency than terrestrial network users, and even frequent outages. Its user experiences are heavily affected by environmental factors such as terrain, solar storms, rain, clouds, and temperature, so is the power consumption. We further analyze Starlink's current bent-pipe relay strategy and its limits, particularly for cross-ocean routes. We have also explored its mobility and portability potentials, and extended our experiments from urban cities to wild remote areas that are facing distinct practical and cultural challenges.
