At the present time, to my knowledge there is no existing satellite systems
in orbit that supports on-board IP processing and routing.
Teledesic has design concepts for IP routing on-board and Astrolink has ATM
switching capability on-board. However,
none of these systems is flying today. Existing commercial systems like
Inmarsat and Cyberstar use IP interface at the ground
to support Internet applications but the space itself is transparent to IP.
NASA ACTS may be the only one today that supports
on-board digital processing (e.g., SONET frames) and not bent pipe
transponder systems.
