special 1-day workshop?<BR><BR><BR>Adrian,<BR><BR>The TCONS and OBL draft red
book were limited to the communications aspects and be the support to the
specifications of the related services at<BR><BR>inter-networking and
intra-networking level that should be the real 'end product'of these WG. and as
such did not provide the full SOIS picture.<BR><BR>Also we agree that this
document presenting an architecure is not per se a 'standard recommendation' but
a support to them.<BR><BR>Green or Magenta Book :<BR><BR>Our intention was to
produce very soon a SOIS green book providing an overall introduction to SOIS as
a whole from TCOAS to TCONS.<BR><BR>Can we understand that the Green Book will
be mainly descriptive giving a nice overall picture without too many technical
details whilst the 'Magenta book'<BR>will be more a guide line/application
profiles book supporting the eventual user/implementer of the
corresponding services standards ?<BR><BR>In this latter case, this magenta
would stay draft for sometime waiting for the outcomes of the prototyping
activities and consolidation of the services specifications.<BR><BR>SOIS
Workshop :<BR><BR>In any case, a SOIS workshop would be welcome. In fact, due to
this long gap between the last meeting and the June meeting, we could organize
one as well in Europe sometimes in the beginning of next year at
ESTEC.<BR><BR>Being said that, I will probably have difficulties to join you for
the last week of October due to project review work one one side but also
because our 'corprorate' mission budget is decreasing as we approach the end of
the year.<BR><BR> In any case, Chris may be able to join since
we have kept some resource for such travel in his contract.<BR><BR>TCOAS:
presence of TCOAS guys will be necessary to get the full story
right<BR><BR>Teleconf: I will set up ta SOIS teleconf to prepare and discuss
this matter in the coming weeks within SOIS<BR><BR>Best

Subject: [CESG] SOIS reference model: special 1-day
workshop? <BR> <BR>
23/09/2005
21:38 <BR> <BR> <BR><BR><BR><BR><BR>Patrick
and Chris:<BR><BR>I was encouraged to see convergence in Atlanta on the need for
a top-level SOIS reference model, and in particular the proposal that the
existing "Time Critical Onboard Network (TCONS) and Onboard Bus Lan (OBL)
Architecture" Red Book might be re-vectored to become the core of a new
Recommended Practice (Magenta Book) that expresses the overall onboard
networking architecture.<BR>The current model (see below) still seems to need
some clarification, particularly in terms of:<BR><BR>1. Showing the Internal
architecture of TCOA 2. Recognizing the application services that can support
plug-n-play operations such as device annunciation and device discovery.<BR>3.
Explaining why the TCONS API is shown in a service diagram.<BR>4.
Differentiating between SOIS and SIS Internetworking services 5. Recognizing
other emerging onboard data buses, such as USB.<BR><BR>At the end of next month
(25-27 October), the CMC and IOAG will meet near Washington DC and many of you
will be coming over for that meeting. On Monday<BR>24 October, the IOAG has a
private meeting and I would like to propose that we hold a special CESG workshop
on that day to focus on getting the overall SOIS Reference Model
agreed.<BR><BR>How many of you would be interested in participating in such a
special SOIS meeting on Monday 24 October? Madeline, Rick, Jane, Greg: would you
guys be interested in hosting this meeting at Goddard? If not, maybe Howie could
host it in Columbia?<BR><BR>Best regards<BR>Adrian<BR>(Embedded image moved to
