Bonjour Michelot,

The client data can be frames. How the stuff and the client data can
be dissociated if the frames are not delineated?
GFP (G.7041) will take care of the delineation).
In G.709 (02/2012), figure D.3, we can see the same number of stuff
bytes than client data bytes. Is it always possible? We can have a
continuous block of 10 000 bytes to map into an OPU unity.
Annex D describes the GMP principle.
Figure D.3 is indeed confusing. If you look at the formulas
(D-10) and (D-11) just above it, you can conlcude that the
number of client data bytes (D) and the number of stuff bytes (S)
is not the same.
Best regards, Huub.
