Dear All,
        here below the initial SLS Comments to IOAG/MOSSG Draft Catalog 3.
Some more comments could arrive later.

Ciao

1) GENERAL: Is the presentation of services in form of concise tables enough
to avoid misunderstanding and to act as clear requirements from IOAG to
CCSDS? Initial impression is NO.
2) The reference to Space Data Link Protocols (and some lower layer
standards) looks limited or questionable.
3) The reference to Packets is limited to Space Packets. Encapsulation Packet
is ignored.
4) The reference to CCSDS seems to identify all CCSDS with MOIMS )or even to
a single WG in MOIMSD). This is of course incorrect (even if MOIMS is the
main - but not unique - addressee of this Catalog) and may drive to some
wrong conclusions by the IOAG WG.
5) How consolidated are the IOAG Priorities mentioned in the document? To
which availability date do they point?
6) The way the AOS Bitstream service is described looks questionable.
7) Does Catalog 3 need no extra service for files more than the terrestrial
file xfer?
8) It looks that Catalog 3 is ignoring the terrestrial file xfer already
required by IOAG and under development in CSCSD?
