Hi Chang,
The Fri slot is tough to dial in from Israel.
Thanks, Aviad

Hi all,

As I promised last week, I'd like to propose an open conference call so that we can set the right expectation for the upcoming working meetings and come up with a plan for them.

I'd like to propose the following options for the conf call. If you have a strict preference to either day, please reply to me directly by tomorrow. I'll collect your votes and announce the result by end of day tomorrow.

- 10 - 11am PST, Thursday (6/25)
- 10 - 11am PST, Friday (6/26)

Once we set the time, I'll send out a link for the conf call.

Note that we intend to have the first "working" meeting in the week of July/6 -- the call we're going to have this week is mainly for planning and logistics, not for in-depth technical discussions (just yet).

Hi P4 developers,

I'm very grateful and super excited to work with this passionate group of experts. Together we'll be able to build a fantastic open-source community, guiding various technical aspects of P4 and the development tools associated with it.

As the first step, I propose that we have a conference call to come up with a plan for the first working meeting. Through the call we'll need to gauge the interest level (i.e., willingness to participate in the working meetings), decide on the schedule (date, time, and interval), gather initial technical agenda, and agree on the format of the meetings.

It seems we could have such a prep call late next week -- either 6/25 (Thu) or 6/26 (Fri). I'll come up with a few specific options within a day or two, so that we could choose a slot that works best for most.

More to come soon ...

Dear P4 developers:

Interest in P4 is picking up at quite a pace and we think it's time to hold regular meetings to guide the evolution of the P4 language and development of open-source tools. We are planning to hold one meeting every two weeks to start with; a mix of in-person meetings and conference calls (details still need to be worked out).

Chang Kim accepted our invitation to chair the P4 meetings to start with. Many of you know Chang already from his days as a PhD student at Princeton with Jen, his tenure with Microsoft Azure Networking, and in his current position at Barefoot. As chair, Chang will gather input from the community, and pick the technical agenda for the meetings.

We've been thinking about how best to run the meetings, so as to keep things simple and informal with as little process as possible. Inspired by the early days of OpenFlow and IETF, this is how we're going to try it to start with:

  *   Anyone can attend the meetings, but P4.org<http://p4.org/> will only be able to accept code contributions from P4 members (who have signed the Apache CLA).
  *   We will adopt a general principle of "rough consensus and running code". No formal votes, just a show of hands to indicate whether we have rough consensus. If it becomes unmanageable, then we'll institute formal voting.
  *   If the meetings really get stuck (which we doubt), Jen and I will help out by acting as "tie breakers".

This is an experiment and we will learn as we go and we will keep revisiting and fine-tuning the approach. At some point we might grow to where we need a little more formality. In the meantime, feel free to email us if you have any questions or suggestions.

Onwards and upwards....

- Jen and Nick
