• About Cn(t) in GMP

    From Michelot@21:1/5 to All on Sun Feb 7 08:52:42 2016
    Bonsoir Huub,

    Sorry for that crasy question.

    In G.709 (02/2012) below the figure D.3, it is noted "Cn(t) client data entities have to be distributed over Pserver locations".

    Suppose 2 176 client bytes to be mapped in Pserver = 3 808 x 4 = 15 232 payload bytes.

    Have we Cn(t)= 2 176 bytes ?

    It would seem it is false because we have never (j × Cn(t)) mod Pserver < Cn(t).

    Best regards,
    Michelot

    Bonjour Michelot,

    There are no crazy questions, only crazy answers... ^_^

    In G.709 (02/2012) below the figure D.3, it is noted "Cn(t) client
    data entities have to be distributed over Pserver locations".

    Indeed. By alternating a number of client data entities and
    stuff entities.

    Suppose 2176 client bytes to be mapped in Pserver = 3808 x 4 =
    15232 payload bytes.

    Have we Cn(t)= 2176 bytes?

    Yes. And because Pserver has 15232 there will be 15232-2176 = 13026
    stuffing entities.
    The stuffing entities will be distributed and inserted between the
    client entities.

    It would seem it is false because we have never (j × Cn(t)) mod
    Pserver < Cn(t).

    Starting with j=1 and applying formulas D-10 and D-11 you will
    that for j=1,2,3,4,5,6 equation D-11 is valid and for j=7
    equation D-10 because (7*2176)= 15232 and
    (7*2176) mod (15232) = 0 and this is < (2176).

    Then for j=8,9,10,11,12,13 D-11 is valid and for J=14 D-10, etc.

    Best regards, Huub.

    Bonjour Huub,

    Many thanks.

    I am really happy to understand, by your efforts to take time and explain very clearly.

    Cordialement,
    Michelot
