Subject: Desiderata - good for LEO too

> Desiderata of Interplanetary Internetworking 

> Go thoughtfully in the knowledge that all interplanetary
communications
> derive from the modulation of radiated energy, and sometimes a planet
will
> be between the source and the destination. Therefore, rely not on
end-to-end
> connectivity at any time, for the universe does not work that way.

> Neither rely on ample bandwidth, for power is scarce out there and the
bit
> error rates are high. Know, too, that signal strength drops off by the
> square of the distance, and there is a lot of distance.

> Consider the preciousness of interplanetary communication links and
restrict
> access to them with all your heart. Protect also the confidentiality
of
> application data or risk losing your customers.

> Therefore be at peace with physics, and expect not to manage the
network in
> closed control loops. Each node must make its own operating choices in
its
> own understanding, for all the others are too far away to ask. Truly,
the
