there are two things here that seem to be one of those "basic conflicts
that MUST NOT be permitted to resolve".....
1) The IETF is not a good place to establish sound engineering princpiles
2) The IETF, in order to work well, must have sound engineering principles
there are two ways to live in this field of conflict:
A - "as it was, it is, and shall forever be" - accept our current
engineering principles as given, and adopt no more. Catenet forever.
B - find a way to adapt, modify and extend our arcitectural prinicples to
adopt new paradigms, new ways of looking at things, and new concepts into
the core of what we call "Internet Architecture"
The IETF does not have an organizational external referent that it can
point to and say "architectural principles come from here". No matter what
the IAB charter may seem to say.
So if the IETF is to adopt something, the IETF has to do the work of
figuring out what to adopt, how to adopt it, and realize that it has
I think the mismatch between the WG short-term engineering model and the
need to do work at a "principles" level is worthy of being called out as
part of our "problem statement".
