CCMAD Packet Format Documentation for BlueField-3 DOCA

Infrastructure & Networking DOCA Enterprise Networking
1

Hello,
I am conducting research on PCC using BlueField-3 with the DOCA SDK. Currently, I am using CCMAD RTT Probe for latency probing.
To implement custom congestion signal notification, I need to modify the CCMAD Custom Header on the switch side. However, I could not find the CCMAD packet format documentation in the DOCA documentation.
Could you please provide information or point me to the documentation that describes the CCMAD packet structure, particularly the Custom Header format?
Any guidance would be greatly appreciated.
Thank you in advance.

Hi,

thanks for your question.

In order to answer it, you may need to open a new support case in Nvidia portal, and it will be handled according to the entitlement.

To Create a New Enterprise Support Case Please Use One of the Following Methods

  1. Log in and Create a Case in the Enterprise Support Portal
    AppHub UI
    This is recommended and will provide the fastest response

  2. Call your Regional Enterprise Support Number
    Find your regional phone numbers:
    NVIDIA Enterprise Customer Support

  3. Create a Case Without a Login
    EnterpriseSupport
    Can be used to check warranty status
    Recommended to reset login passwords
    Requires validation and may increase time to respond

Best Regards,
