I'm from the Clockwork team, thanks for listing the relevant papers.

Accurate clocks sync enables true one-way delay measurements (instead of RTT/2), this allows for edge-based network visibility. We launched Latency Sensei beta – a sensor, monitor and auditor that provides visibility into cloud deployments. The gallery has cloud fitness reports on GCP, AWS and Azure. Some interesting reports include: 1)how VM colocation impairs network bandwidth, and 2) tale of 2 cloud regions, London vs Singapore. Take a look and we'd love to get some feedback https://sensei.clockwork.io/user/gallery/

On Congestion control, an edge-based solution is coming soon. If you're interested in a private beta, email us at [e-mail]
