<> P4 Apps library
TNA has been opened, the
need to create a library or "app store" for P4 code is higher. Apps WG has a repository, time to think about logistics.
Artifacts for each app:
runnable P4 + control plane code, test script, document.
Document to specify Barefoot
SDE version (in cast of TNA), an inventory of artifacts, and sufficient description to enable the artifacts to be exercised.
Vetting process: manual
review at the beginning. Automatic integration with SDE and testing will be needed.
ONF staff can help with
actual hosting, maintenance.
Questions:
- what if the app requires a modification of Barefoot switch.p4, which is not open? A patch to switch.p4 can be shared?
- What about non-p4 apps, such as INT implementation in DPDK or eBPF under a license different from Apache2 that P4.org uses?
Action items: JK will
follow up on the questions and share.

Broadcast/Unknown Unicast/Multicast traffic handling in INT
Ramesh: There has been not much discussion around BUM traffic. IOAM had a presentation document for capturing multicast branch ID as part of hop metadata.
Mickey: for BCAST, MCAST, how about �force� bit to report the entire tree and branches?
AI: Ramesh will make a proposal to discuss in the next meeting.
<> INT-MX, source-only
feedback
We walked through a few known use cases of source-only data and found the proposed categorization help clarifying their semantics.
We also briefly talked about UDP port number requirements for INT and Telemetry Report.
In the next meeting,
- we will continue the BUM discussion,
- follow up on PRs from Mickey
- discuss INT with IPSEC
Thanks,
JK
