I agree with your idea regarding use cases both in MO file services and CSS TGFT.

My concern is how to share information between SM&C and CSS, because
CSS area recognizes MO File Management Service as approved new project
in the level of CESG-to-CMC report. However, it is out of scope in document

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,

| Sam-san,
| I have quickly checked the draft, because I cannot join discussion next Wednesday's morning.
| I have just one comment about File Transfer Service.
| File Transfer Service would be similar to TGFT (TERRESTRIAL GENERIC FILE TRANSFER)
| which is currently drafted in CSS SM WG and is described in IOAG service catalog #1, on the condition that interoperability is limited to ground-to-ground.
| My understanding is that TGFT is based on the HTTP PUT method  and the mechanism by which the injection to/from a CFDP entity is managed is out of scope.
| If use case is limited to monitor data transfer between grounds, there will be
| MO file services or TGFT.
| I suggest that SM&C will share information with CSS SM WG
| through joint meeting next May, because at least SM WG does not know our file services.
