Hi Alex,
Thanks, I might have been unclear.
By “where” I meant to make a difference between the core
infrastructure and “edges“, where the latter can be considered
limited domains that need to interconnect to the Internet (the core)
but as well among them not necessarily going through a centralized
service.
Is it clearer?
YEs, it is clearer: a core-edge balance of localisation of innovation in
the Internet, in addition to the addressing aspect.
With respect to where is Internet innovation situated - in the edge or
in the core: I think most patents are developped at the edges, in the
limited domains. There is where it is easier to innovate. A patent for
a technology in the core network would have a hard time to be agreed. I
dont know whether there are patents on BGP in the DFZ, or on DNS at
root, but I think not.
With respect to addressing: the ULA addressing is an exemplary facet of
how limited domains might use a different addressing than the Internet
at large. However, ULA is still IP addressing - the 128bit addresses.
Should one innovate in the edges, rebuild the edges rather than touching
on the core, and concentrate all 'addressing' work in in designing of
translation mechanisms? Yes, but would that significantly slow down the
Internet? If at every packet forward one has to look up a translation
table then it might be expensive. More energy-consuming big boxes to
translate and to offer new opportunities of controlling that translation?

had a very nice discussion in the previous thread about what
kind of features we would want from the Internet. We wanted to
come back on another interesting point that has been raised
during the side meeting held during IETF 112, namely is where the
innovation happening?
Do you mean on what layer in the stack is innovation happening?
Do you mean on which part of the network: the end node, the core?
Do you mean where on Earth is it happening?

During the discussion in the side meeting, there was a short
exchange between Dino, arguing about “decentralization”, and
Michael stating that we are “rebuilding the edges”; the
importance of the role of overlays was also briefly mentioned.
This is not a simple question, and may lead to an architectural
argument, in line with Dirk K.’s viewpoint that only such
architecture discussion may lead to possible changes to
addressing, but also something that emerged in the previous
thread. However, let’s at least start from the addressing
perspective. Rebuilding the edges and utilizing decentralization
may point to some approach to addressing that is not governed by
a common addressing scheme. For instance, could we instead see a
diversity of limited domain specific addressing schemes with
most effort in ‘addressing’ being placed into the context
translation that will need to inevitably happen? Or shall we
instead follow the current path that forces the same context (IP
semantics) to all participating edges (which goes counter the
‘rebuilding the edges’ comment)? Hence the question we would like
to discuss with you on: how/where innovation, realizing the
features discussed in the previous thread, should happen? This
can help in strengthening the conclusion of the Problem Statement
document
(https://datatracker.ietf.org/doc/draft-jia-intarea-scenarios-problems-addressing/
<https://datatracker.ietf.org/doc/draft-jia-intarea-scenarios-problems-addressing/>),
in order to provide input on which way to tackle the problem.
