[dtn-interest] IANA registry for LTP (and the BP?)

[Stephen Farrell <[e-mail]>]

The comment we got about LTP extensions was:

I think (anyone know for sure?) that the relevant guidelines here
are BCP 26. [1]

So the questions are whether or not to do this for LTP extensions
(and maybe ciphersuites) and secondly for extensible bits of the
BP (block types, ciphersuites, anything else?).

And if we do want any IANA registries, then what rules should
we adopt for updates?

I guess there is the possibility that CCSDS's DTN group might
want to extend LTP and/or the BP, so maybe it is a good idea
for us to think about this now. If anyone knows of other groups
that might want to create their own extensions or blocks that'd
be useful input here too.

As I said in the other mail, my plan for LTP would be to create
a new draft-irtf-dtnrg-ltp-iana to document whatever it is we
think is the right thing to do. (If anyone wants to take on
doing that, let Kevin and I know.)

Thoughts?

Stephen.
