Not everyone shares Tony and TIPTOP's "IP networks only" notion
of how space networking will play out. Many of us, including
experts from many space agencies, believe that Bundle Protocol
(BP) based networks are intergal parts of a Solar System
Internet, just as IP based surface networks on Earth are and
eventually the Moon, Mars, Europa, etc. will be.
Honestly, what is the demand of it in terms of devices, networks right
now and for the next few years ?
Taking aggregation out of the equation, what would be the issue of using
IP space allocated by the RIRs to space agencies with supposedly pretty
low demand.
Do you believe the present system, as is, has competency for
management of BP related resources by the RIR system. We accept the
management of IP resources by the RIRs because RIR participants
generally know IP networking very well. I will wager that the level
of BP related knowledge is not as strong among this group, yet
resources from both will be required to participate in the LunaNet.
It might be preferable for a participant to get these resources from
one source. There are ways to accomplish this without new RIRs, but
it does involve the existing RIRs to build the relevant competence and
infrastructure to support management of these resources.
Yes I do. It is well established and can accommodate as necessary. It
has the basis to adapt to whatever necessary and acquire the necessary
technical competence. Furthermore RIRs represent the interest of each
regional internet community worldwide.
Really don't understand by some wish to bypass the RIR system and create
something new and unknown for something that doesn't have justified demand.

Hi all,
I tried to attend the session on TIPTOP, but was
unable to do so.
There were many comments that came up that I’d like
to respond to.
1) Space is outside of ARIN’s charter.
This is absolutely true. It’s outside of
everyone’s
charter. It was not part of anyone’s thinking
when the RIR
system was first established. This is an
oversight that
needs to be corrected. John mentioned the
example of
Antartica, which I think is apropos. A small
demand,
which ARIN handles for the good of the global
community.
I think space should be handled the same way.
It was suggested that space should get its own RIR.
While
that’s possible, that would create an entire
organization for a
handful of constituents with maybe a dozen requests
per year and
lacking the expertise that ARIN has. To my mind,
this would be
as inefficient as an independent RIR for Antartica.
Space is outside of ARIN’s current charter. ARIN
should broaden
its reach and include space. Because someone has to
and ARIN
can.
2) This doesn’t guarantee aggregation.
Absolutely true. This is not regulation. But
this is
enablement. Aggregation cannot happen if
allocations are
not done properly. This is the status quo.
This intent of this policy is to enable aggregation.
The space
agencies involved are strongly motivated to keep
their overhead
costs down and keep their routing efficient. We can
provide the
technical expertise to make this happen, but none of
that can
happen if we have dispersed addressing.
3) Latency is the driver for the IPv4 portion of the
policy.
The issue is bandwidth, not latency. Space
vehicles are
very bandwidth limited and communications are
mission
critical, so efficiency is paramount. For this
reason,
missions are being flown with IPv4 today and
will likely
continue to do so. While access to IPv6
prefixes for
higher bandwidth provides for future missions
with higher
bandwidth, for today’s missions where
bandwidth is
severely constrained, we want to encourage
mission
planners to aggregate within IPv4.
Cheers,
Tony
