I have been developing an application that would benefit from faster, more reliable, and ideally synchronized, communication. This led me to look at whether we could implement the App using the TSN open-source provided by OPC Foundation and open62541 Foundation. It appears we can, however, there appear to be some specific hardware requirements (bridges, etc.) that are not available by default when communicating across the internet. Is that correct? Or does a standard, fast, domestic fibre connection do what we need?

Also, it seems like the internet already provides Precision Time Protocol PTP communications for audio visual applications under 802.1Qav. This may in fact be a good starting point for us, so can someone explain if would be feasible to use OPC UA / open62541 with 802.1Qav. I realize we wont achieve the same level of synchronization but the speed should increase. (FYI I am a Systems Engineer not Networking engineer!)

Up to now we have been using the default implementation of OPC UA from Open Foundation and open62541, it does not use TSN for sure, and as far as I can tell, it does not use PTP. The default does work, however, communications are very slow across the internet. When we run the same simulations on our local network we get somewhat acceptable results.
