IBM FASP protocol

I have not heard of that but it could be a good reason to use an existing solution 
based on Python or C++ or other as offered here

Hi Hoi, nice to see you in the community. You piqued my curiosity about FASP and I found this white paper about it: https://www.ibm.com/downloads/cas/7D3KBL9Z.

I don't see any support for this in our class reference.  If you are looking for support for this in InterSystems IRIS, I would start with your InterSystems account team to explore what you need and what alternatives might serve.
