[Fiware-iot] New picture whole IoT Architecture

Hi Tobias, all,

Accordingly, the picture should be this one.

Hi Carsten, Thierry, all

In the new architecture picture sent by Thierry last week I see a slight inconsistency, because the TH is connected to the IoT Broker GE at the Northbound interface (the one where data consumers are connected) and the TH is connected to the ConfMan GE via the interface where the data providers are connected.

According to the current discussion the TH GE possibly plays both roles, but still we might consider making the NGSI 10 and NGSI 9 connections aligned. If the data consumer role is the more important one, this would mean connecting the TH to the ConfMan via the left-hand NGSI9 interface.

Best regards
Tobias

Hi Tobias,

>>Does it also serve as a data provider? So does it e.g. register its templates as entities in the Config Management, so that the IoT Broker GE would request data from the TH when applications ask for it?

Ah I see, no, so far it is only a consumer, but I will check if we can register the templates in the Config Management, this would definitely make sense.

best regards,
Carsten

Hi Carsten,

Thanks a lot for the link and the explanations!

>From reading the descriptions I come to the conclusion that from the IoT Broker perspective the TH is an application (data consumer) retrieving for data.

Does it also serve as a data provider? So does it e.g. register its templates as entities in the Config Management, so that the IoT Broker GE would request data from the TH when applications ask for it?

Hi Tobias,

yes, as I said, an application using the Template Handler (not the TH itself) will need to interact with the other components. The TH will subscribe to events (subscribeContextRequest) in order to be notified of sensor readings (notifyContextRequest). The respective flow chart and some description is here:

Hi Carsten,

Are there already flow charts and/or examples showing how the Template Handler interacts with the other components?

Hi Tobias, hi all,

the Template Handler needs to be provided with the entities, i.e. it will not query the Conf Man actively, but wait for an NGSI start event. This is, however, I believe not necessarily a problem in the architectural picture, as the relationships between the components are not directed anyway. That means, an application using the Template Handler will need to interact with the other components in order to be able to build the appropriate start event for the Template Handler.

Best regards,
Carsten

Hi Thierry, all,

It is a bit unclear to me how the Template Handler interacts with the GEs it is connected to (Context Broker, IoT Broker, Conf. Man., Be Device Man.).
Can someone clarify?

Thanks & best regards
Tobias

Hi All,

Here is the new picture for the whole IoT architecture including some previous changes and Template Handler. Please check and comment if anything seems unclear or wrong.
