<p>Thanks, Calin and team. I think this is a very good direction
to go. We need to find the right blend of portability, while
still allowing for different architectures. Having a base set of
functions created for a baseline/portable architecture -
features that we can expect to work on a variety of forwarding
planes - will let different teams write code they can expect to
re-use (completely or mostly). I think we're all conscious of
not trying to boil the ocean; the proposal seems like a good
step forward.<br>
</p>
<p>Over time, I expect/hope there will be other baseline
architectures for P4-16, representing different use cases. For
now, I like the idea of focusing on something as you propose, to
get the ball rolling and help us build a community together.</p>
<p>As for a name, I think Portable or Baseline or PISA are all
good. PISA has the advantage of being known already and used in
the context of P4-14, and so would be my preference. It would
also help PISA to be a generic name for an architecture, rather
than just a name for one design.<br>
</p>
<p>Thanks</p>

<div class="">We made some progress toward defining the standard
switch architecture (therein named Portable Switch
Architecture in order to avoid the overbearing connotations of
the word Standard) and I would like to propose that we set
aside some time to discuss the attached proposal at our next
working group meeting on Mon 11/7. Early feedback is welcomed
and encouraged.<br class="">
