How to DIY the congestion control protocol for cx6

Hello, everyone!
I am looking for how to program and deploy my DIY congestion control algorithm. However, I cannot find any API to do so. Could somebody share it with me?
Many thanks!

Hello @zhu9999,

Thank you for posting your query on our community. ConnectX-6 Dx added a Programmable Congestion Control HW. We have a PCC Development Package UM that we can provide.

I would like to request you to submit a support ticket by emailing “Networking-support@nvidia.com”. Please note that an active support contract would be required for the same. For contracts information, please feel free to reach out to our contracts team at " Networking-Contracts@nvidia.com "
