TCP Congestion Control Performance over Starlink

Proceedings of the Applied Networking Research Workshop on ZZZ
We examine the performance of 14 different Linux TCP congestion control (CC) variants over Starlink connectivity. We then focus on the two most commonly used CCs, BBR and Cubic, and the best performing other CC, Illinois. Multiple measurement campaigns were conducted to evaluate throughput performance for single and multiple flows, examine how the ...

The Thermosphere Was Poorly Predictable Not Only During but Also Before and After the Starlink Storm on 3–4 February 2022

Geophysical Research Letters
Observation‐based simulations of the ionosphere were performed with the NRLMSISE‐00 model for six locations around the globe during 1–9 February 2022, which includes the so‐called Starlink Storm. Unlike other studies, we focused on the magnetically quiet
