Insights from Netflix on QoE — a 5G-MAG Tech Talk with Dr. Renata Teixeira, Staff Research Scientist at Netflix, on streaming over Low Earth Orbit (LEO) satellite networks.

Abstract
Low Earth Orbit (LEO) Satellite Networks bring broadband to new places — and new challenges to streaming. Netflix measurements from millions of households in 147 countries show that LEO now represents a meaningful share of global streaming traffic. Overall quality can match terrestrial access, yet rapid throughput swings and packet-loss bursts increase bitrate switches and stall risk.
The talk characterizes these effects and LEO's growing role in video delivery, maps the tradeoffs for transport and adaptive bitrate algorithms, and outlines priorities for future work on LEO streaming. It builds on the SIGMETRICS 2025 study “A Global Perspective on the Past, Present, and Future of Video Streaming over Starlink”, in collaboration with Liz Izhikevich (UCLA), Reese Enghardt (Netflix), and Te-Yuan Huang (Netflix).
Speaker Bio
Renata Teixeira is a Staff Research Scientist on the Streaming Algorithms team at Netflix. She earned a Ph.D. in Computer Science from UC San Diego in 2005, conducting research on Internet routing at AT&T Research. From 2006 to 2013 she was a researcher at CNRS/LIP6 (UPMC Sorbonne Universités) in Paris, and from 2013 to 2020 a Director of Research at Inria Paris. She was a visiting scholar at UC Berkeley/ICSI (2011) and Stanford University (2018–2020). Her work focuses on quality of experience and the measurement, analysis, and management of data networks. She is an ACM Distinguished Member, received the ACM IMC Test of Time Award in 2022 for Paris traceroute, and was recognized in 2017 as an N2Women “Star in Computer Networking and Communications.”
This talk was organized under 5G-MAG's WG TECH working group.
