Why does Mysql Server Communicate with Client via Listen Socket? : <p>Generally ,when a server accepts a TCP request in the first time ,it will get a new socket from operation system for subsequent communications .
For example ,the relevant function is <code>Socket java.net.ServerSocket.accept()</code> in java .
But notice what I see when I Use <code>netstat -anp|grep mysql</code> command. All the mysql communication sockets are using the 3306 port .</p>

<p>How to explain ?</p>
