The IETF has standardized a new protocol for having two network queues at bottleneck links via L4S (Low Latency, Low Loss, Scalable Throughput) and NQB (Non-Queue-Building Per Hop Behavior). These new standards may be able to significantly lower "working" latency (latency under load) for better real-time traffic performance and to support new AR and VR applications.
This talk will explain how dual queue networking works and explains what network operators need to do to support this - including allowing end-to-end passing of ECN marks and the use of DSCP-45 across domain boundaries.
