UDP instream limit


Is there a max number of edge devices that can send data to a UDP-IN node. For instance, a gateway running node-red and it listens for incoming UDP packets and the number of UDP messages is proportional to the number of edge devices sending data to the gateway. I am assuming this is also HW dependent but I would like to know if the UDP-IN has a limit for many-to-one communications.


Hello and welcome,
I don't think there is any fundamental limits built in. As you already said the main dependency will be hardware and the underlying operating system and it's performance. - but also maybe what you are doing downstream in the rest of the flow.
