Re: [irtf-discuss] Update on "Challenges for the Internet Routing Infrastructure Introduced by Changes"

Well I guess for IRTF it would be great to talk about the research that is
done or the one you want to propose in the field. You yes very much focus
on “what was”.

Thanks Marie-José,

Yes, this is certainly work that is needed.

We should present a little more about the architectures that people are
considering, and the split of address/metadata/data is a helpful
distinction. In fact, the metadata/data is largely historic, and we're
looking at the various proposals to encode information in the address.
Perhaps our draft currently has too much information about previous work,
and not enough about current proposals -- work in progress!

I just want to note that it's not our new addressing 😊. What we're trying
to do is collect information about all of the proposals and research that
are out there.

The pointer to COIN is helpful, and we'll try to factor something into the
next revision.

Best,
Adrian

I think it would be nice if your document was putting more focus on the
proposed architecture and the applications that could need your new
addressing. Also I think there are three layers here: address (IP or IP
like), meta data and data. Of course you could route on any or all of them
which I think is what you propose. And the more you go from simple ‘this is
where I want to go’ into how and why complexity increases and speed goes
down. Maybe you should also highlight performance aspects more clearly.
There is a link to the COIN work where discovery and essentially in-router
computations would add new potential for routing algorithms.
