Deborah
Perhaps my biggest problem is I don’t drink coffee and it is early morning.
But let me try anyway. (maybe I will chug a beer).

I totally agree with you.
We (Enterprises) are not as involved as we should be in IETF, and that is our own problem/fault.
What I think irritates people like Stephen, is that there have been situations where we finally try to get involved and provide input/use cases, etc., but at the 11th hour or after the ship has pretty much sailed.

So as you say Deborah, I very much want to get more Enterprises involved in IETF initiatives,  but beyond that, being involved up front in the process (perhaps even making positive contributions OMG),  rather than only whining about deployment/operational issues on the back end.   (or explaining why they exist, which is essentially what I was doing on this issue ☹).

How to accomplish this is a challenge and I think that is what Barbara suggested taking off to the other list.

Thanks

Mike

As Stephen said, couldn’t resist, first cup of coffee-

That’s always the question of the day- what is an operator, vendor, researcher?

I know “academia” on this list that have more operational experience than some in operator communities. We know in big companies there are so many people - but not necessary interested in ietf. And people switch - few are “lifetime” at a company. To me, no hats, just want more input.

My point (I think Mike also) is simply to get more involved, earlier if possible in our rinse cycle to RFC.

Deborah

Hi,

What is the definition of “enterprise”?

Thanks,
Rob

Thanks so much for your informative and positive message.

I have not followed the OPs area too much, but will make an effort to do so now.   Any specific drafts you might suggest, I will review.   In particular,  I am interested in what specific IPv6 document from the OPs area you refer too?



I took a look at the ISOC IPv6 doc you listed.   Interesting but it appears to be quite old.   Do you feel it is still relevant?    Enterprises need a lot of info on IPv6 and I want to point them in the most effective directions.

By increasing visibility, do you mean ways to get Enterprises more involved or aware of IETF?     I can sadly say none that have yet been effective, but I do intend to keep trying.   Perhaps you have ideas?



And finally, I checked out your Pragmatic Link.  Still laughing, even though it unfortunately seems to have very little relevance to my world 😊



Once again I really appreciate your constructive comments and  information.



Mike

As Barbara builds her confidence for the IETF list and while we have Mike's attention-



Mike, you commented "More, it is a lack of understanding of how things work within Enterprise Networks and the lack of Enterprise engagement in Standards Development processes. And finally, this may not be a gap that the IETF should care about or address, but someone should, IMHO."



I wanted to +1 on to Barbara's message - many of us will say - "we do care". As IETF is "huge" (for many operators/users that is the biggest bottleneck on participating), not sure if you follow the ops area (I'm a routing AD, but ops always has my attention😊), they have several documents on enterprises. Currently a document on the impact of TLS1.3 on operational network security practices. They also have an IPv6 one. I think in all the Areas (I know best the routing area), we encourage operators and users to participate. If you have suggestions - we are interested.



How to increase visibility? Do you have suggestions? Liaisons? ISOC? When RFC7381 (Enterprise IPv6) was done, it was an ISOC blog:

https://www.internetsociety.org/blog/2014/10/new-rfc-7381-enterprise-ipv6-deployment-guidelines/<https://urldefense.com/v3/__https:/www.internetsociety.org/blog/2014/10/new-rfc-7381-enterprise-ipv6-deployment-guidelines/__;!!BhdT!zmG3F1slksg8AtkdGf3Lkkb9Lpbn1ePVRYSyQggUh92yK8Xb7tvzVDr-EG6n_mk$>



Possibly this draft should be a blog? Suggestions?



Thanks again for the interesting thread- Deborah for some humor - I'm still stumbling on the draft's requirement "Pragmatically, clients MUST NOT send". I'm not sure operationally how to ensure pragmatic client behavior - maybe a "pragmatic client" profile😊 I'll save that question for my ballot comment. And of course a google of pragmatic is very entertaining:

Ow! Mike is my friend. Don't go dissing my friend!



I think the problem in communication we've just experienced is because Mike strayed away from Last Call discussion on a specific document, to asking/discussing a more general question of how IETF can better communicate with enterprises and perhaps even engage with enterprises to make it easier to operationalize protocols inside enterprise networks. I didn't see Mike suggesting any changes to the draft in Last Call, relevant to this question. ?



I'd like to suggest that maybe we could discuss this a little more on the ietf list? But not here.

I'll see what happens if I start a thread over there (ietf@ietf.org<mailto:ietf@ietf.org>) ...

[Let me drum up my courage first. Thinking about posting to that list is much more stressful to me than, for example, thinking about bungie jumping off the Macau Tower -- an experience I highly recommend.]
