Poster: QueuePilot: Towards Adaptive Queue Scheduling via Live Digital Twins

Year: 2025

Type: conference-paper

Abstract: Queue management policies strongly influence latency, loss, and fairness, yet production switches often rely on static configurations. Changing policies in the wild is risky, as experiments can disrupt SLAs and queue dynamics are hard to reproduce offline. We present QueuePilot, a digital twin for switch queues that enables safe, traffic-driven evaluation of scheduling and Active Queue Management (AQM) policies. Our prototype, built on two Tofino switches, clones live traffic into the twin, multiplexes it across multiple queueing strategies, and monitors real-time fine-grained metrics. Preliminary results show that QueuePilot can synchronize with the production queues and simultaneously evaluate alternative queuing policies, allowing precise real-time queue management without affecting live traffic.
