Will the TCP-INT function be added?

[jackmygreat]

In-band telemetry is an important feature, are there plans to add TCP-INT to the code?

Do you mean this code? https://github.com/p4lang/p4app-TCP-INT

[jackmygreat]

This project uses the code from TCP-INT. TCP-INT has a separate p4 code at https://www.intel.com/content/www/us/en/products/network-io/programmable-ethernet-switch/connectivity-education-hub/research-program.html

Sorry, yes I checked after I posted my comment above, and that reminded me that the P4 code for the Tofino part of TCP-INT is not in that repository.

I can ping @pkotikal to see if she knows the answer. I do not know if there are plans to add Tofino TCP-INT P4 code to this, or any other, public repository.

Thank you very much. I have another question. I have a machine with bf-sde9.2 deployed. The TCP_INT code is in bf-sde9.2.1. I found that they are only different in the pkgsrc/switch-p4-16 directory. Can I copy the switch-p4-16 directory of TCP-INT to the current bf-sde9.2 machine, and then only compile switch-p4-16? Because it takes a long time to fully compile SDE.

I do not know for certain, but I'd recommend to try it and see what happens. Also, note that In the time it takes to await an answer, I'd bet your computer could have finished fully compiling another version of the SDE.
