<span style=" font-size:10pt;font-family:sans-serif">Hello<br>
<br>
This was discussed in length with Wolfgang Hell at the time we discontinued
pass specific SICF.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">In term of security,
the added value of pass specific SICF is close to nil.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">In term of operational
failure, the handling of pass specific was causing lose of service on a
monthly basis. </span>
<br><span style=" font-size:10pt;font-family:sans-serif">And the recovery
action was to use permanent SICF. So what the point.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I have experienced
the usage of pass specific SICF, and I can insure you this is not something
you want to see in human spaceflight operation.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Cyber security
has to be taken seriously. </span>
<br><span style=" font-size:10pt;font-family:sans-serif">Pass specific
SICF is not a serious answer to today threat.<br>

<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt;font-family:Georgia">Just
to add a quick comments to this thread, the DSN also employs permanent
SICFs for SLE instance configurations. Much like what Colin has indicated
the implementers complained that it was just too much trouble to deal with
dynamic SICFs as that would involve more testing and more things could
go wrong, etc. However given the changing cyber security landscape I would
ask if, eventually, can you afford not to have dynamically generated SICFs
or some other equivalent such that access is very much controlled on a
tracking pass by tracking pass basis – especially if you are supporting
human spaceflight? I think it is something we should keep an eye on.</span></p>

Marcin,</span><span style=" font-size:11pt;font-family:Calibri"> </span><span style=" font-size:10pt;font-family:Arial"><br>
I remember having implemented SLE SICF generation for our scheduling system
(2008?) and I think we have put some thinking in how to do that. As Colin
correctly remarks, the feature of pass specific SICFs is not used - simply
too many files.</span><span style=" font-size:11pt;font-family:Calibri">
<br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
However, the trick at the time was to distribute the information for SLE
SICF creation to the two relevant places: The mission agreement with the
(SLE) service requirements and the ground station model with the ground
station capabilities (amongothers the SLE services supported formulated
as templates). The two are used for determine 'does the station have the
required capabilities' and then to combine the information as shown below
to the configuration (slide 45 of attachment):</span><span style=" font-size:11pt;font-family:Calibri">

</span><span style=" font-size:11pt;font-family:Calibri"> <br>
<br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
Some background: Our scheduling is service based, so in addition to the
SLE services we define the underlying production services as operational
services (TM, TC, DDOR, Ranging, etc.), which are required (mission agreement)
and matched with station capabilities (station model). Those production
services are in fact subject to configuration profiles, which can be refined
by missions per pass or requested service.</span><span style=" font-size:11pt;font-family:Calibri">
</span><span style=" font-size:10pt;font-family:Arial"><br>
In orinciple the complete configuration profiles could be defined by FRM
parameters.</span><span style=" font-size:11pt;font-family:Calibri"> <br>

Hi Marcin, Anthony,</span><span style=" font-size:12pt;font-family:Calibri">
</span><span style=" font-size:10pt;font-family:Calibri"><br>
ESOC has effectivly
moved to permanent SICfs. The NIS (Neywork Interface System - Handles MCS
- Groundstation SLE links) was designed to be able to use dynamic as well
as permanent SICFs and the missions screamed about the prospect of having
to use dynamic ones, much preferring to use permanent ones.</span><span style=" font-size:12pt;font-family:Calibri">

As I would see it, and as I think we had it in the old Blue-1 book, the
service instance identifiers and the parameters you feel are missing are
part of the service package, not the SA or CP. Your 3 spacecraft configurations
would be 3 configuration profiles. The SP request may identify a specific
station or antenna; at any rate, the SP itself will identify the aperture
and the service instances, and at least port IDs. <br>
There was a discussion which I don’t think was ever fully resolved, about
service instance identifiers. The original concept had them being dynamically
defined for each service package. But the “stop-gap” SICF approach ended
up with people getting used to “permanent” SI IDs and being reluctant
to change that. Certainly I think it would be unhelpful to have to reproduce
the same config multiple times just to use different SI IDs for different
apertures. <br>
Basically what you suggest in your second and third bullets looks about
right, modulo discussion on permanence of SI IDs.</span><span style=" font-size:11pt;font-family:Calibri">

</span><span style=" font-size:11pt;font-family:Calibri"> </span><span style=" font-size:10pt;color:#004080;font-family:Calibri"><br>
I think the FRM parameters identified as just “reporting” mean they cannot
be changed during production. Clearly they have to be set somewhere, i.e.
“by management”, as part of setting up the service packages.</span><span style=" font-size:11pt;font-family:Calibri">

In course of some implementation work and discussion with my developers,
I came to the point where I think we shall have some closer discussion
soon (in one of our teleconferences and definitely later during spring
meetings).</span><span style=" font-size:11pt;font-family:Calibri"> </span><span style=" font-size:10pt;font-family:Calibri"><br>

The Synopsis: during implementation of VEEEEEERY remotely similar profiles
into DLR’s new scheduling system, my developers asked me how they shall
treat the Service Instance Identifiers in the profile. When I looked at
their initial implementation, I noticed, that they did put the complete
configuration (service) profile in “one piece”, according to the current
list from FRM and to what I told them. It does not correspond to the full
flexibility of the actual planned SACP (this was not the intention). Anyhow,
I realized two things: </span></p>
<br><a name="Gruß"></a><span style=" font-size:10pt"><br>
1. Not all of SLE parameters were there (GVCID,
Port and User identifiers, etc…) <br>
2. Defined as such now, projects would need
to define multiple configuration profiles, being actually the same, differing
only with Service Instance Identifier, for each Service Instance. In our
case, for example for TerraSAR mission, we have actual 3 spacecraft configurations
for the antenna, but in total 32 service instances for different stations,
antennas and cortexes. This maybe does not multiply 1x1, but at least we
would need 32 configuration profiles (I can almost hear the project people
coming to get me)! <br>
</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
Okay, this is to some extent my own fault, as I burdened the implementation
of “some kind of configuration profile” to my developers, and maybe did
not thought about it in front. But it shows I think also some shortcomings
we have with the concept (maybe it will shape up still).</span><span style=" font-size:12pt">
</span><span style=" font-size:10pt"><br>
</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
To the first point, I quickly noticed, that – even I made a list of parameters
based on FRM – actually not all parameters are really exposed. When looking
to the export of Holger out of FRM and the schema files, I noticed than
there is number of parameters which are marked only as “reporting” thus
in first place not visible to SACP (hence my omission). And so, all Initiator
and Responder Id’s as well as PortId’s and the GVCID’s are marked as
“reporting” or “read-only” if you like. How are we going to set them?
<b>Shouldn’t they be also configurable, similar like Service Instance
ID?</b></span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>

</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
Second topic is the actual (operational) separation of the antenna configuration
and the transfer services configuration. Currently (at least at DLR) this
looks like this:</span><span style=" font-size:12pt"> <br>

There are few antenna configurations (which may be effectively also identical
throughout different antennas) and number of SLE configurations (Service
Instances). To be fully honest, the multiplication of the SLE config is
just due to the different Responder ID and Port ID’s, resulting also in
separate Service Instance ID, the rest of the config is typically the same
(for a specific RCF or FCLTU service).</span><span style=" font-size:12pt">

How do we want to handle that with our current concept of SACP?</b></span><span style=" font-size:12pt">

I know we had some brief discussions on that, and there is some three page
(chapter 3.4.2) information on intended use in the TechNote of John. It
speaks relatively high level about two options, reusing SICF files (kind
of an extension to the actual SACP config) and also by dynamically setting
the abovementioned parameters. <br>
</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
First option says, that SICF files shall be there, and the Responder and
Provider ID’s and Ports shall be fixed in Service Agreement and for specific
Site and Mission, and later on only these shall be used. It does not actually
however says anything on how actual SICF is bound to the specific Service
Package nor Service Package Request nor Configuration Profile. We have
Ports and their ID’s, but how do I know which SICF shall I use? Shall
there be also predefined ONE fixed SICF?</span><span style=" font-size:12pt">

Second option of using the extended/abstract parameters in Service Package
may allow for dynamic provision of the so called “scheduledSocket”
which would be just the ProviderPort. So far so good, but still I miss
the rest of the SLE/CSTS configuration, especially wrt to what I wrote
above.</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>

here some discussion. ?</b></span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>

I was thinking – just to came into with some proposal – of the following
(better ideas are welcome!):</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
- To not destroy everything else we already
somehow managed to set up wrt SMURF, SPDF and SACP…</span><span style=" font-size:12pt">
</span><span style=" font-size:10pt"><br>
- …We could use extended list (as at
the beginning) in the Service profile, with Service Instance ID, PortID’s,
GVCID’s etc., having predefined some parameters (i.e. Buffer sizes), whereas
leaving all of these “variable ones” undefined. That way we would have
limited number of Configuration Profiles (a set of few generic ones for
the spacecraft, universally engageable in every station).</span><span style=" font-size:12pt">
</span><span style=" font-size:10pt"><br>
- When booking the Service Package (sending
the Request) we could “overwrite” the previously mentioned parameters
using AbstractParameter Class (for example “InitiatiorID” and “ServiceInstanceID”
and “GVCID”). The same would be true for SPDF – the values there would
be shown in AbstractParameter class (and for example additionally station
defined PortID would be provided). This would allow to use all of our Books
/ Formates as they are, and have individual SLE configuration for each
pass/service package.</span><span style=" font-size:12pt"> </span><span style=" font-size:10pt"><br>
- The disadvantage of the above method
would be, that there would need to be some kind of automated generation
of Service Instance ID and GVCID on user side and the ProviderPort on provider
side. Otherwise we come into danger of crazy users/providers not filling
these parameters, or filling them wrongly or even filling them different.</span><span style=" font-size:12pt">
