We're please to announce the two winners of the ACM SIGCOMM Test of Time Award 2026:

1️⃣ “A buffer-based approach to rate adaptation: evidence from a large video streaming service” Te-Yuan (TY) Huang, Ramesh Johari, Nick McKeown, Matthew Trunnell, Mark Watson. ACM SIGCOMM CCR Volume 44, Issue 4, 2014.

For a comprehensive design and real-world analysis of approaches to adaptive video streaming, showing the effectiveness of using buffer occupancy as the key control variable.

2️⃣ “A Control-Theoretic Approach for Dynamic Adaptive Video Streaming over HTTP” Xiaoqi Yin, Abhishek Jindal, Vyas Sekar, Bruno Sinopoli. ACM SIGCOMM CCR, Volume 45, Issue 4, 2015.

For a thorough exploration of the design space for adaptive video streaming that provides a principled framework for delivering high quality of experience across varying conditions.

Together these papers have had a lasting impact on the design and understanding of adaptive video streaming and continue to influence both research and practice more than a decade later.

Thanks to Bruce Davie (chair, Systems Approach), Keith Winstein (Stanford University), Radhika Mittal (UIUC), and Teemu Koponen (Apple) for serving on the 2026 Test of Time Award Committee.

RE: https://discuss.systems/@ACM_SIGCOMM/116038378175027279

We have recently received requests from prospective authors in conflict-affected regions who are facing difficulties completing their intended submissions due to the escalating situation. The APNet’26 Program Committee and Organizing Committee fully recognize these challenges and sincerely empathize with researchers working under such circumstances.

APNet’26 has decided to extend the submission deadline to March 11 AoE (hard deadline) to provide additional time for those impacted while maintaining fairness to all authors. We hope this extension will offer meaningful flexibility and support a successful submission process.

We are excited to invite submissions to the Posters & Demos track at SIGCOMM 2026!
Submissions are 2 pages and the deadline is May 15, 2026.

Whether you’re exploring a novel networking concept, building a system prototype, or testing a disruptive idea, we encourage you to submit and engage with the community.
