server

I have a defined number of servers that can locally process data in their own way. But after some time I want to synchronize some states that are common on each server. My idea was that establish a TCP connection from each server to the other servers like a mesh network.

My problem is that in what order do I make the connections since there is no "master" server here, so that each server is responsible for creating there own connections to each server.

My idea was that make each server connect and if the server that is getting connected already has a connection to the connecting server, then just drop the connection.

But how do I handle the fact that 2 servers is trying to connect at the same time? Because then I get 2 TCP connections instead of 1.

Any ideas?
