Hi,

As one of the most active members during the last round discussions, here are my summary of that round:

1.           BIERin6 is to apply the existing generic solution to IPv6 networks, with a clean layered architecture. All that is needed are code points for outer header to indicate the payload is BIER. In case of IPv6 tunneling (single hop or multi-hop), that's a code point for IP "next header".
2.           It does satisfy all requirements listed in the requirements draft, including supporting SRv6 based services.
3.           With the above considerations, it is ready for WG adoption on standards track, and should not be tied with other solutions (which may progress on their own paces).

[External Email. Be cautious of content]

Since Mike invoked me, I'll make my adoption comments in response to his mail.

Looking back at the list, I saw a couple of +1s to my suggestion, and a mumble from an author of draft-zhang-bier-bierin6 about Experimental not being fair.

I'm surprised to see this adoption poll without first resolving the debate about precedence of I-Ds and not even an announcement from the chairs about a plan for how the two I-Ds will be progressed. Adoption, IMHO, is not about whether a draft is technically ready, but about how the WG wants to address a topic. I don't think we have resolved that question, and so I think an adoption poll on one draft only appears to be prejudging that debate.

So I would like us to suspend this adoption poll and sort ourselves out first.

Thanks,
Adrian

Oppose.

We are unfortunately no where near consensus on this topic including this draft. We'll likely see that during this adoption call.

Adrian's suggestion for consensus remains the best I've heard: simultaneously call to adopt both solutions as experimental.
