Learn about STORM, a novel multipath QUIC scheduler designed to optimize streaming media transport on unstable mobile networks in this 20-minute conference presentation from USENIX ATC '25. Discover how researchers from East China Normal University analyzed the challenges of multipath transport for streaming applications, revealing that path instability causes excessive end-to-end latency primarily due to "last mile" wireless links rather than core network issues. Explore the key insight that existing multipath schedulers fail to account for the reliability characteristics of mixed reliable and unreliable data transmission in streaming scenarios. Understand how STORM addresses this gap by differentiating between reliable and unreliable traffic to prevent retransmissions from hindering critical data flows, and examine its integration with mobile device wireless modules including WiFi and 5G. Review the impressive evaluation results showing STORM reduces tail packet delay by 98.2% and improves streaming media frame rates by 1.95x compared to state-of-the-art solutions under unstable network conditions.
