Push Model vs Pull model:

You can get all the traffic using GET and you can do that when you want
Open UDP and every second you get data feed.
Push model: we send the data and
Pull model: I don’t want it every second ,but every 10 seconds.
Limit information send or received: Transmit mode / receive mode.
Most of sensors are push (real time tracking). Some others have pull. (90% are push since it is Ethernet device)

@andreaslamprecht Thank you for this, as in the earlier case, the idea is to write a section about pull-vs-push to highlight some considerations. Of course it is up to the individual manufacturer to accomodate accordingly. Thanks again, I will send on a notification when I have completed these.

if you want to look at statistical data, then don't limit yourself to the aviation industry. Look at Gaming, IoT, Videostreaming, ...

does this really need to be standardized? Those questions are really more relevant for a product-specification, not for an industry-standardization.

I agree, push vs. pull is rather a function and ability of the overall processing network, and you could easily switch between them with aggregator nodes that aggregate pushed observations. A common example is prometheus (used to monitor datacenter infrastructure at scale): it supports both push and pull and leaves it to the concrete use-case to take a proper decision.

@vosst Thanks for this. I will add the Prometheus example link in the per their FAQ

Closing issue since this is addressed in the "Push Vs. Pull" section of the appendix.
