Hi All,
During the last INTArea meeting the discussion on the two drafts related to
Internet addressing had three the clear outcomes:
1. The issue seems to go beyond what the INTArea has been chartered for.
2. The pain points (aka the problem) have to be scoped in a better way.
In the current form, the scope is so broad that we risk ending up trying to
boil the ocean without achieving any relevant result.
3. Incremental deployability remains a MUST. No revolution. Evolution is
the only option.
Concerning point 1. The documents have been taken out from INTArea (new
naming). We still continue the discussion on the INTArea mailing list, at least
temporarily with the option to have a dedicated mailing list in the future.
I would like to restart discuss on point 2: the scope.
The considerations draft
(https://datatracker.ietf.org/doc/draft-iannone-internet-addressing-considerations/
<https://datatracker.ietf.org/doc/draft-iannone-internet-addressing-considerations/>)
highlighted three properties, namely:
Property 1: Fixed Address Length
Property 2: Ambiguous Address Semantic
Property 3: Limited Address Semantic Support
But before going to the discussion of which property we should/want change the
first question the comes up is: what does an address identify exactly?
A simple answer would be: an Interface.
But we all know that reality is far more complex, as pointed out with the many
existing examples in the considerations draft.
What is even more complex is how to provide a wealth of answers to the above
question within a framework for evolved addressing that does not rely on the
continued point-wise approach we see in the Internet today.
In order to start specifying what this evolved addressing framework could be,
the first steps are:
- paraphrasing Lixia Zhang’s question from the recent RTG WG interim
meeting as “What should we identify through an address?”
- scope the work around those answers we believe are most desirable to
avoid the boiling the ocean issue
Do you believe this is a reasonable approach to move forward?
Luigi
