What is the correct way to forward messages to a bunch of clients?

Question

Android

I sent the server address via udp-broadcast, the clients joined and sent their addresses to the server, what is the right way to send the message from the client to all other clients?

Answer 1

Use zeromq and don't worry

Answer 2

Either send a message via upd to all received addresses, or clients initiate tcp connections and receive messages through them.
