Subject: DLUR/DLUS Names

I am coming to this late in the day but I assume you are debating
an acronym for the proposed 3270 dependent LU support in APPN.
 
I think DLUr and DLUs are great architectural terms and DLUx ("deluxe")
is a great play on words (after all the combination of hierarchical and
peer-peer SNA has to be the deluxe version of SNA - the one everyone
wants, we hope!) but think that a reference should be made to 3270 somewhere.
The term Dependent LU (DLU) alone (without reference to 3270) is possibly too
general in scope. I am guessing that the DLUs/DLUr proposal does NOT include
support for the mid-range dependent LUs (i.e. AS/400s, System 3x and 5x94s)
which amongst other things uses FID3 Transmission Headers (which are only
2 bytes wide) and hence can't be routed in an APPN network in a fashion similar
to the 3270 FID2 THs.
 
So I vote (if I have one) for DLUs/r and DLUx as architectural names but think
the feature (i.e. 3270 Dependent LU routing using APPN) name or title should
contain a reference to 3270.

Nit: Not all dependent LUs are 3270.  LU 6.2 sessions can also be dependent
LUs.  There may not be a lot of SNA traffic over dependent LU 6.2 but it
does exist nonetheless.
