Dual Queue Networking - How to Prepare Your Network to Support L4S and NQB

Learn about the latest IETF standardized protocol for implementing dual network queues at bottleneck links through a 33-minute NANOG conference talk. Explore how L4S (Low Latency, Low Loss, Scalable Throughput) and NQB (Non-Queue-Building Per Hop Behavior) can significantly reduce working latency for enhanced real-time traffic performance and support emerging AR/VR applications. Gain practical insights into implementing dual queue networking, including essential requirements like end-to-end ECN mark passing and DSCP-45 usage across domain boundaries.
