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 <> 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.
