Student of Computer Science currently based in Aachen, Germany. I'm mostly interested in Networking and DevOps / SRE / Production Engineering. Isn't it pure magic when code from the developers' notebook gets automatically deployed to 25 datacenters on 7 continents?

IM Video Calls Performance Study

Have you ever wondered how novel (mobile) Instant Messaging Video Conferencing applications such as Signal, WhatsApp or Telegram select their sending rate amidst varying network conditions and congestion? In 2022, I conducted measurements at the COMSYS chair of Aachen University. We presented the results at TMA 2023 in Naples. Here, you may find the conference paper and the associated data and software repository.
