Martin,
As an Area Director, what are your thoughts regarding Bruno's claim that
this working group (Spring) doesn't have the necessary skills for
evaluating the need of a functionality (PSP) that this wg is including
in draft-ietf-spring-srv6-network-programming?
Specifically, Bruno has noted (in
https://mailarchive.ietf.org/arch/msg/spring/or8086G4iYfee5_Icw4PnhkPLBo/):
---- cut here ----
Independently of RFC 8200, the question has been raised with regards to
the benefit of PSP.
My take is that PSP is an optional data plane optimization. Judging its
level of usefulness is very hardware and implementation dependent. It
may range anywhere from "not needed" to "required for my platform"
(deployed if you are network operator, or been sold if you are a
vendor), with possible intermediate points along "n% packet processing
gain", or "required when combined with a specific other feature". I
don't think that the SPRING WG can really evaluate this point (lack of
hardware knowledge, lack of detailed information on the hardwares).
---- cut here ----
Doesn't this sound a bit like a group is shipping something that it
cannot really understand?
Thanks,
Fernando

WG,
as I had indicated in a previous message I am the one evaluating
consensus for this WG LC.
I have carefully read the discussions on the list. I acknowledge that
disagreements were expressed regarding what a particular piece of text
of RFC 8200 says, and on which this document builds to propose an
optional capability. Since RFC 8200 is not a product of the SPRING WG, I
have paid specific attention to the messages ([1], [2], and [3]) sent by
the responsible AD of 6MAN and of RFC8200.
My overall conclusion is that there is support and rough consensus to
move this document to the next stage.
Bruno will handle the immediate next steps.
Martin

Hello SPRING,
This email starts a two weeks Working Group Last Call on
draft-ietf-spring-srv6-network-programming [1].
Please read this document if you haven't read the most recent version,
and send your comments to the SPRING WG list, no later than December 20.
You may copy the 6MAN WG for IPv6 related comment, but consider not
duplicating emails on the 6MAN mailing list for the comments which are
only spring specifics.
If you are raising a point which you expect will be specifically
debated on the mailing list, consider using a specific email/thread
for this point.
This may help avoiding that the thread become specific to this point
and that other points get forgotten (or that the thread get converted
into parallel independent discussions)
Thank you,
Bruno
