[Css-csts] RE: functional resource types for Retrieval Service Package components?

[Marcin.Gnat at dlr.de]

Hi John,

Maybe you could clarify that to me -  I do not see maybe the obvious things.
And anyway, I'm also not so deep into CSTS as you.

What is the actual difference between online and offline services? I mean, why should I want to control the on-line stuff, and things which come later (offline) not?
Reason I'm asking is, we have some offline services which produce the service based on some specific information provided to the ground station (or better to say, to the storage). The information is a kind of a request for sending these and that frame range from the data dump id-such-and-such. Does it fall under eventual CSTS in-band monitoring & control? What would be an example of (probably not needed from us) control service on such offline transfer?

Regards
Marcin

Subject: [Smwg] functional resource types for Retrieval Service Package components?

SMWG and CSTSWG colleagues -
I'm in the process of walking through a detailed scenario involving the scheduling and execution of a Service Package that has Monitored Data and Service Control services. In particular, I'm looking at how the functional resource types and associated parameters, events, and directives that are monitored and controlled (respectively) are properly correlated to the Service Package.

Until now, I think it's safe to say that we have all been thinking about the Monitored Data and Service Control services as being associated with Space Link Sessions. Does anyone envision monitoring or controlling offline services (outside of the in-band capabilities provided by the respective transfer services)? I personally cannot come up with a reason to do so, especially since for SLE transfer services and CSTSes we have essentially built in any monitoring that seems necessary.

If we do not see a need to monitor or control offline services, do we need to define functional resource types corresponding to offline service resources? The original purpose for defining functional resource types was to provide a structure for naming monitored parameter values and notified events (and then extended to cover directives); what, if any, other purpose does a functional resource designation serve?

If you have an opinion on this I'd like to hear it.

Thanks.

Best regards,
John
