QUIC as specified in drafts does not use Cubic but I expect most implementations to use it. Winquic is doing Cubic already. Are you proposing that quic cc should do the ABE experiment by default? Has its safety been proven by a wide deployment? I asked this q in tcpm and the answer was no.

Subject: [Ecn-in-quic] ECN-in-Quic w/ ABE

Just a quick note to those present here:

ABE (Alternative Backoff for ECN) is past WGLC in TCPM, allowing a differntiated CC control between ECN and Loss - to incentivise the deployment of ECN.

Since Quic uses Cubic, the guidance given there for differential reaction between loss and ECN marks would be directly applicable...

Any thoughts?

Best regards,
  Richard
