Re: Oops! Accepting Enterprise Scenarios as WG Item



Alain,

Sorry I'm just getting to this now, but I don't agree with your
point that the "...design team is way too 'transition tool' centric
in its approach...". In section 4, we see the following paragraph:

 "This document will identify those Points of Transition and discuss
  them within a set of scenarios. This document will not provide
  solutions. A set of suggested solutions will be provided in a follow
  on document to this work."

To me, this paragraph seems to be setting the appropriate scope for
the document and is not at all 'transition tool' centric. Am I missing
your point? In any event, I do think the current document takes the
right approach (albeit a bit light on text in some sections) and I
support it becoming a wg item.

Margaret,

First, I would like to say that I appreciate the effort of the
design team to address such a difficult issue.

However, that said, I'm not very comfortable with this document.
On one hand, it is badly needed and already very late,
on the other hand, I'm not sure it is taking the right direction.

I already have commented several times that this design team
is way too 'transition tool' centric in its approach, somehow making the hidden
assumption that solving the 'enterprise' case in the (yet to come) analysis/solution
document will consist only of picking the 'right' transition tool developed by NGtrans.

What I would like to see are things like the following
instantiated for a set of 'typical' enterprise environment:

- how does the internal networks looks like?
- how is the networks are managed?
(who is responsible, what is outsourced, is IT competent/reliable or not ...)
- what are the procedure/tools in place to manage the network?
(not only SNMP, but for example tools to create DNS zone files)
- is the public internet used (via VPN...)?
- what are the connections to the Internet?
- Is the v4 address space private or public?
- Is the v4 address space 'portable'? (hint: do they need portable v6 address space)
- How much v4 address space is available?
- Are they multi-homed?
- how is security enforced?
- how does the datacenter looks like if there is one?
- what kind of applications are used in the Internet/intranet/extranets/...)
(is it in-house code? is the source code available? is an Ipv6 version of the
code available to buy?....)
- how naming service/directory service is performed (two face DNS?)
-...



There is a little of that buried in section 4, variable description,
but I think this document should really instantiate those variables
and more (the ones I just described above for example, certainly much more)
in a set of several 'typical' enterprise environments instead of focusing
on cases describing how enterprises are thinking of deploying v6 at the IP level
(section 5, which is basically which networks to connect) or abstract cases of transition mechanisms
(section 6, point of transition methods) which belongs not in this document
but in the solution document.

With this in mind, I would not recommend the wg adopting this document.

- Alain.
