Dear Int-area
As attached below, i have written up an idea about why and how variable-length
addresses in the network layer would be useful for many limited domain
internetworks,
but also how they could provide a simple and easily extensible framework to
add additional semantics (the likes of multicast, BIER, ICN), and also make it
easier
to express the programmability that SRv6 introduced.
Would very much welcome discussion/feedback, and will be asking for a slot
to present/discuss this int-area 111.
Note that the -00 writeup is mostly inspirational for what i think the cool
things one could do with it are and to explain the concepts.
Obviously, if/when there is interest in this
direction, the harder work of figuring out how to best introduce this
incrementally, and ideally backward compatible into existing networks wold
be the next big set of items to work out.
Cheers
Toerless
