Merging P4 programs has several issues to deal with.  We have documented the issues at our P4-Ansible link below.

Thanks! The audio is on the datatracker for coinrg: https://datatracker.ietf.org/rg/coinrg/meetings/

I didn’t attend the IETF nor did I listen to any meeting minutes, if any audio exists.  Going by the pdf Marie-Jose sent out, item 6 is interesting to me.  

 

Dave Oran asked merging two P4 programs.  A uses case is being discussed in the P4 community.  An operator is using a P4 switch from Cisco/Arista.   However, the operator has some new service in mind.  The operator writes his/her P4 program.  How does the operator (customer) merge the customer with vendor P4 program?  Cisco was first with an incremental P4 merging tool called daPIPE.  My company also developed a tool called P4-Ansible (https://mnkcg.com/products/p4-ansible/).  Cisco only supports p4-14 programs.  Our tool supports p4-16 programs and much more.  Such merging of P4 programs changes firmware of the switch asic.  Thus, the switch data plane has to reset to run the new merged P4 programs.  The switch cpu operates control-plane and continue to run.  The whole switch doesn’t need a reset. 

 

Regarding, changing P4 program without resetting switch data-plane, one can change tables and table actions of the MAU (Match-Action Unit) in data plane.  P4runtime (https://s3-us-west-2.amazonaws.com/p4runtime/docs/master/P4Runtime-Spec.html) is used for such changes.
