Is that possible that a server in the network start communicating with three clients sending data request to all the three clients and waiting for their response ?
Your model of networking differs from mine to the extent that I don't think I can help.
I tend to think of the device that initiates a transaction as being a Client, and a device that responds to that by sending back data as being a Server.
I guess there must be some implementation limit to how many IP sockets you can open simultaneously, I can't cite a source, but I don't suppose it is as low as 3.
Without knowing anything about your planned data-gathering, perhaps this is a situation where MQTT would provide a solution in preference to using 'web' technology?
