/**
 * Factory to create various types of sockets. For socket creation, a service name can be passed as argument:
 * an implementation could look up a service description (e.g. port) and create the socket, ignoring the passed port and
 * possibly also the bind address.

 * Ephemeral ports can be created by passing 0 as port, or (if the port is ignored), an implementation could pass in
 * a special service name (e.g. "EPHEMERAL"), this is implementation dependent.

 * The socket creation methods have the same parameter lists as the socket constructors, e.g.
 * {@link #createServerSocket(String, int, int)} is the same as {@link java.net.ServerSocket#ServerSocket(int, int)}.
