Privonet VPN service - Cybertec
Privonet VPN service is supported on Cybertec routers from FW 1.7.2.0.
As you can see at the bottom of the page.

Time to test the stability of the connection and able to retrieve data over relatively longer time period. Two tests been executed:
- Test-1: 4 hours
- Test-2: 12 hours
I did not use ICMP
(normal ping
), but instead used TCP. This is the package tcp-ping and you can read up on advantage of not using ICMP
as well.
To demonstrate remote data acquisition, I used following timing. Poll every 2 minutes. In most cases I would consider this quite aggressive for industrial application, but I wanted to capture potential VPN drop outs and how that would affect data collection.
Results
Here are results for 12 hours test.

Results indicates time period of approximately 8 continuous minutes (the worst case scenario), where unit was not reachable.
That represents 0.9% of total time, where unit has not been available.
12hours = 720min / 8min = 90 / 100 = 0.9%
Note: Check average ping time.
Here is a screenshot from plotting the results.

With the LTE unit (unit has been connected the whole time to LTE) are results are great 100% online.
Note: Check average ping time.
Average ping time on LTE network (138.883 ms
) is not even 50% of average on 3G network (300.175 ms
).
