Deploy standard internets in low latency remote environments (e.g., on other planets)
Support dialog
across a network
of Internets
The Basic IPN Concept:
construct a
“Network of Internets”
Connect distributed internets via an interplanetary backbone
Long propagation delays
Backbone contact periods:
• short relative to delay
• possibly one-way
• possibly separated by
  days, weeks
• cannot guarantee an
  end-to-end path
Operations driven
by power, weight,
volume
Transaction sizes are
small compared to
bandwidth-delay product
High value data,
finite buffers
