I wonder what the latency is going to be on this. It needs to be at least 1/30th of a second round trip but I suspect the actual latency is going to be more like 1s+
In reality it's probably even faster since neither side is dealing with Wi-Fi.
Dublin is about 10-50 times further from NY than you are from that datacenter, and the speed of light is a universal limit.
Latency will be far more than that due to speed of light.
My mpeg vision circuits are about 480ms end to end from Washington/New York to London. The j2k ones are faster but still in the 200ms range. In theory you could get it down to sub 100ms but at that point you are certainly having to engineer your paths correctly and use barely any compression.
Uncompressed 4k is in the 10gbit range. My uhd jxs bitrates are about 1.3gbit but wouldn’t deliver sub 200 across the pond.
1/30th of 1s is almost exactly the round-trip time from NYC to Dublin (Wolfram Alpha says 17ms one-way).
Assuming travel across the earth surface, light in a vacuum take about 14ms to cross the distances. Times two for round trip that’s about 1/30 s.
Of course we don’t have anywhere near ideal conditions there (at a minimum, light in fiber is already slower, closer to 40ms round trip in that case, and of course network infrastructure adds orders of magnitude), but it’s a good limit.
If so, I don't see how this is any different. If not, that's a pretty narrow definition of realtime given the context.
If we talk about medical equipment, it may be very different based on the equipment.
Real time OSs advertise maximum guaranteed latencies. 0 latency does not exist in the physical world, the speed of light can’t be convinced to hurry up, unfortunately.
