CFDP CCSDS File Delivery Protocol
It's a file/message transfer protocol designed for space links. And
I mean links that aren't just to earth orbit where TCP almost works.
Look at <http://www.ccsds.org/itshot.html> under reviews in process.
If you are in the USA (so we don't have to fight ITAR restrictions on
spacecraft data) then we have a prototype implementation we can
probably give you. It's been tested against two European and a
Japanese implementation of the Red-4 version of the protocol and the
Red-5 version is the result of those tests. This should be very
close to the final.
