ISP Dual Queue Networking Deployment Observations

The IETF's Transport and Services Working Group (TSVWG) has finalized experimental RFCs for Low Latency, Low Loss, Scalable Throughput (L4S) and new Non-Queue-Building (NQB) per hop behavior. These documents describe a new architecture and protocol for deploying low latency networking. Since deployment decisions are left to implementers, this document explores some of the implications of those decisions and makes suggestions that can help drive adoption and acceptance of L4S and NQB based on observations from the world's first large scale deployment.
