[NNagain] A Multifaceted Look at Starlink Performance

[rjmcmahon]

I'm curious at what's needed by iperf here to help with connection 
timeouts.

>> ABSTRACT
>> In recent years, Low-Earth Orbit (LEO) mega-constellations have
>> ushered in a new era for ubiquitous Internet access. The Starlink
>> network from SpaceX stands out as the only commercial LEO network
>> with over 2M+ customers and more than 4000 operational satellites.
>> In this paper, we conduct a first-of-its-kind extensive
>> multi-faceted analysis of Starlink performance leveraging several
>> measurement sources. First, based on 19.2M crowdsourced M-Lab speed
>> tests from 34 countries since 2021, we analyze Starlink global
>> performance relative to terrestrial cellular networks. Second, we
>> examine Starlink’s ability to support real-time latency and
>> bandwidth-critical applications by analyzing the performance of (i)
>> Zoom conferencing, and (ii) Luna cloud gaming, comparing it to 5G
>> and fiber. Third, we perform measurements from Starlink-enabled RIPE
>> Atlas probes to shed light on the last-mile access and other factors
>> affecting its performance. Finally, we conduct controlled
>> experiments from Starlink dishes in two countries and analyze the
>> impact of globally synchronized “15-second reconfiguration
>> intervals” of the satellite links that cause substantial latency
>> and throughput variations. Our unique analysis paints the most
>> comprehensive picture of Starlink’s global and last-mile
>> performance to date.

>> 1 INTRODUCTION
>> Over the past two decades, the Internet’s reach has grown rapidly,
>> driven by innovations and investments in wireless access [22, 46,
>> 47] (both cellular and WiFi) and fiber backhaul deployment that has
>> interconnected the globe [3, 8, 10, 24, 77]. Yet, the emergence of
>> Low-Earth Orbit (LEO) satellite networking, spearheaded by ventures
>> like Starlink [65], OneWeb [49], and Kuiper [4], is poised to
>> revolutionize global connectivity. LEO networks consist of
>> megaconstellations with thousands of satellites orbiting at
>> 300–2000 km altitudes, promising ubiquitous low latency coverage
>> worldwide. Consequently, these networks are morphing into “global
>> ISPs” capable of challenging existing Internet monopolies [66],
>> bridging connectivity gaps in remote regions [36, 69], and providing
>> support in disaster-struck regions with impaired terrestrial
>> infrastructure [21]...
