摘要:

低地球轨道卫星网络(LSN)一直被认为是即将到来的6G真正全球覆盖的关键基础设施。本文介绍了我们的初步测量结果和观察的Starlink的端到端网络特性,可以说是迄今为止最大的LSN星座。我们的研究结果证实,LSNs是一个很有前途的解决方案,无处不在的互联网覆盖在地球上,然而,我们也发现,Starlink的用户体验更多的动态吞吐量和延迟比地面网络用户,甚至频繁中断。其用户体验受到地形、太阳风暴、雨水、云层和温度等环境因素的严重影响,功耗也是如此。我们进一步分析了Starlink目前的管道中继策略及其局限性,特别是对于跨洋航线。我们还探索了其移动性和便携性的潜力,并将我们的实验从城市扩展到面临独特实际和文化挑战的偏远地区。

英文摘要:

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.
