+1. I like this approach given our focus to get a good release out in Nov.

@Oliver – I share your concern about having 32 projects and gating the release 
with deliverables from each one.

What I would like to propose is categorization of “core” and “non-core” (or a 
less derogatory name) projects. Core projects are those that provide the 
minimum viable product functionality, e.g. A&AI, Modeling, SO, etc. Some 
projects seem like providing functionality beyond the MVP, such as CLAMP, 
Holmes, etc. Some projects will fall somewhere in between and we could use our 
common sense to categorize them.

This way the community could focus on reviewing the core projects first, and 
the release will be gated by deliverables from these projects only. This does 
not mean that non-core projects will not be approved and worked on in the first 
release, assuming they are defined, approved and have contributors.

There are of course some bad implementation examples of such categorization 
(OpenStack “Big Tent” anybody?) but I believe we can avoid past mistakes and 
make this approach work for the benefit of the community.

Ranny.

For the areas in which I have contributions to consider, here are some 
clarifications.

First, the Common Controller Framework should have overlap as far as scope with 
a lot of projects.  That is the point of that project, to find overlapping 
functionality, develop it in a single project, and reuse it among the other 
components.  So I would not be concerned with any overlap between CCF and the 
other projects dealing with deployment, management, orchestration, etc.  That 
is by design.

For DCAE: we have recognized an overlap with Holmes, which in my view should be 
a sub-project of DCAE, but it does not appear that sub-projects were proposed 
this way.  DMaaP does not have an overlap with DCAE.  DCAE uses DMaaP, as do 
many other components, but the scopes are completely different.  I believe the 
functionality in DMaaP for data processing does not exist today and it is not 
clear that it would be part of an open-source release of DMaaP or not anyway.

For DMaaP: The CCF overlap is by design.  It is our intention to provide a 
“Data Bus Controller” with responsibility for deploying and managing DMaaP data 
delivery components where they are needed and when they are needed.  That 
functionality exists in DCAE today, but needs to be pulled out to be generally 
available across ONAP components.

For MSB: I agree this should be part of CCF.  It could be used by DCAE and OOM.

I just went through the proposals and noticed that quite a few of them have not 
clearly defined boundaries between them which makes me wonder if they overlap 
(see table below). From experience overlapping project definitions rarely lead 
to good outcomes (duplicate work gets done and people are very upset at the 
end…) so I think we should resolve this before approving the projects.

When I built this table I focused on what’s written in the proposals. Now from 
discussions I think some of the perceived overlaps might just be a matter of 
cleaning up the writing. Others might actually be real. In either case I think 
we need to be clear and precise in the project description and can’t rely on 
various email exchanges for this.  I also don’t claim that my table is 
complete. If you want I can put the table on the Wiki so people can add there 
perceived or real overlaps.

I don’t know how you usually resolve those issues but I would think that the 
project leads for all projects which might have an overlap define a common 
statement which defines there relationship with each other in some level of 
detail. Thoughts?

I also looked at the use cases. Lingli and her team did a great job cleaning up 
the VoLTE use case:

https://wiki.onap.org/pages/viewpage.action?pageId=3246140<https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.onap.org_pages_viewpage.action-3FpageId-3D3246140&d=DwMGaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=mSWkj6dIUv40CROVujozu_XlxP5keHDQDHDFr5pdK8c&m=1vCiffQlW45jG2jvHk7jIkWuy-A-H0iAdyYLQwP5aeg&s=6HyvFwD1dgzt-cvOGcGtY7E2YnvsWItIZDMv3gvgcSc&e=>

The flow charts are a great start but we do need to get into more details and 
actually show the real API calls as well. I am also not sure I understand how 
exactly the legacy Open-O and legacy ECOMP components integrate. I think the 
next step here is to walk through this in detail. I don’t think that’s 
something that can be done efficiently via email. I would suggest a call on the 
topic. That might actually be better then a F2F in June as it allows more 
developers to dial in.

One concern on this particular  use case is that only Huawei and ZTE have any 
VNFs in it. Personally I don’t think it’s a good start for an open project to 
start with proprietary VNFs from mainly one manufacturer with some contribution 
from a second. I wouldn’t even know how that worked in practice. E.g. will 
those VNFs be available to competing vendors so they can test/develop ONAP code?

This brings me to overall use case scope and reality.

Using Gilda’s release plan (all his fault after all :)) we have to work all of 
this out by 6/29 (sounds a lot of time but really isn’t). Development is only 3 
months till RC0. We have 32 projects. That’s 21 projects more then the seed 
code of 8+3. If I ignore the toy use case we have two use cases proposed with 
the VoLTE one having more details then the other.  Coordinating interfaces one 
on one for the 32 projects requires 512 meetings. ….  I think if we are trying 
to achieve all of this in release 1 we are setting ourselves up for failure.

If it was up to me I would probably just focus the use cases on instantiation 
and one simple control loop. This might seem like very little but considering 
the work we need to start the projects, set up the labs, get developers 
familiar with the environment, get them lab access  etc… which all takes time.  
I think that would be realistic for a first release and then we can adjust the 
second release accordingly.

 In terms of projects I would be very careful which projects have deliverables 
in release 1.0. . I don’t think having deliverable in release 1.0 is a gating 
function of getting a project approved. So the TSC can approve projects that 
make sense but as said I would discourage some of them to have a contribution 
to the 1.0 release.


Probably just stating the obvious … .
