Java: is it possible for a client to use same port on remote computer twice?

Let me clarify the question.

See the digram Digram

Is such connection possible with all the four sockets running simultaneously!

ServerSocket is the ServerSocket from java.net API normal Socket is Socket from java.net Api

And yes by ServerSocket I mean the socket returned from ServerSocket.accept after connection is established

Solution

  • Have you tried it?

    Yes, it is possible as one communication end is defined by ip address and port together. As both servers will have different ip addresses there will be no problem.

    Also thought about the internet? Nearly all web servers are running on port 80 and it works just fine.
