However, this causes a fundamental dependency on ECN-based transport protocols, making it hard to use generic transport protocols. To this end, we design DynaQ, a protocol-independent multi-queue management solution that enables service queue isolation with generic transport protocols. DynaQ dynamically adjusts the packet dropping threshold of service queues. Our solution is inexpensive to implement on hardware. Through extensive testbed experiments and large-scale simulations, we show that compared to alternative schemes, DynaQ is the only solution that achieves work-conserving weighted fair sharing and low latency without protocol dependency.
