Dear all,

I also have no budget remaining for another US trip. Pre-prepared
material can be made available; it's not difficult to draw the TCOAS
architecture!

Regards,

Stuart

Adrian,

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

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.

Also we agree that this document presenting an architecure is not per se
a 'standard recommendation' but a support to them.

Green or Magenta Book :

Our intention was to produce very soon a SOIS green book providing an
overall introduction to SOIS as a whole from TCOAS to TCONS.

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'
will be more a guide line/application profiles  book supporting the
eventual user/implementer of the corresponding services standards ?

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.

SOIS Workshop :

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.

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.

 In any case, Chris may  be able to join  since we have kept some
resource for such travel in his contract.

TCOAS: presence of TCOAS guys will be necessary to get the full story
right

Teleconf: I will set up ta SOIS teleconf to prepare and discuss this
matter in the coming weeks within SOIS

Best regards

Patrick

Patrick and Chris:

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.
The current model (see below) still seems to need some clarification,
particularly in terms of:

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.
3. Explaining why the TCONS API is shown in a service diagram.
4. Differentiating between SOIS and SIS Internetworking services 5.
Recognizing other emerging onboard data buses, such as USB.

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
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.

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?

Best regards
Adrian
