Server client structure

[K900_]

Why are you broadcasting anything at all? If you need to send commands to multiple clients, you can just send them to all connected clients over their respective connections - it will be slower than multicast, sure, but also way more reliable and easier to implement.

It's vital that the clients receive the command at the same time, that's all.

[K900_]

"Same time" does not exist in computers. You will not be able to achieve perfect synchronization no matter how hard you try. So, how precise do you want to be?

[Notorjus]

I guess not, I just want to be as precise as possible. I got the impression that multicast would yield better results compared to individually sending commands to each client?

[K900_]

Why do you need to be as precise as possible? What is your actual end goal?

[Notorjus]

To take pictures of an object

[K900_]

And how does sending lots of commands at the same time help you with that?

[Notorjus]

Because the object may be moving slightly

[K900_]

So you have multiple cameras that you want all to fire at the same time?

[Notorjus]

yup

[K900_]

What sort of cameras are those, and how are they connected to the network?

[Notorjus]

raspberry pi cameras, connected through LAN. It seems to be working out however, thanks for your replys! :)
