Hi Miyano,

Thank you for that, we'll certain look at this during the meeting.

The idea with the MO file transfer management services is that it 
provides a single service interface regardless of the actual mechanism 
required for the transfer (this is not currently shown in the document). 
So you would use it to "talk" CFDP over a space-link, possibly TGFT when 
transferring files to/from a ground station, possibly FTP in other 
ground parts etc.

Hope this helps,
