At the same time, the interplay of CC and AQM is also evolving but congestion unresponsiveness remains a threat. In particular, L4S crucially requires a fine-grained CC and AQM interaction to provide its benefits and suffers from unresponsive traffic. Overall, we need more responsive traffic on the Internet as well as mechanisms that can cope with unresponsiveness. We present Congestion-Responsive Queuing (CRQ), our L4S-inspired system which is designed to promote responsive CC, manage unresponsive traffic, and handle QUIC and TCP flows alike. Similar to L4S, CRQ uses two queues for flow isolation. Yet, in contrast to L4S, we isolate flows based on their actual congestion responsiveness, moving responsive flows to one queue and leaving the remaining flows in the other. Our evaluation with an eBPF prototype highlights the efficacy of our design and shows that CRQ can provide effective incentives for responsive CC. https://www.comsys.rwth-aachen.de/fileadmin/papers/2025/2025-kunze-crq.pdf IEEE Proceedings of the 2025 IEEE/IFIP Network Operations and Management Symposium (NOMS '25), May 12-16, 2025, Honolulu, HI, USA Honolulu, HI, USA 2025 IEEE/IFIP Network Operations and Management Symposium May 12-16, 2025 accepted 1 IkeKunze ConstantinSander MikeKosek LarsTissen JanPennekamp KlausWehrle inproceedings 2023-sander-quic-ecn 2023 10 legato https://www.comsys.rwth-aachen.de/fileadmin/papers/2023/2023-sander-quic-ecn.pdf https://arxiv.org/abs/2309.14273 ACM Proceedings of the Internet Measurement Conference (IMC '23) Internet Measurement Conference 2023 979-8-4007-0382-9/23/10 10.1145/3618257.3624821 1 ConstantinSander IkeKunze LeoBlöcher MikeKosek KlausWehrle inproceedings 2020-kosek-tcp-conformance 2020 3 30 maki https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-kosek-tcp-conformance-v2.pdf https://arxiv.org/abs/2002.05400 Springer Proceedings of the Passive and Active Measurement Conference (PAM '20) Eugene, Oregon, USA Passive and Active Measurement Conference (PAM 2020) 30.03.2020 - 31.03.2020 en https://doi.org/10.1007/978-3-030-44081-7_8 1 MikeKosek LeoBlöcher JanRüth TorstenZimmermann OliverHohlfeld
