When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.

The system configuration change here refers to the change of activity life cycle caused by the switching of horizontal and vertical screens, thus causing the change of resources. In Android, system configuration changes will cause activity destruction and reconstruction, such as horizontal and vertical screen switching, but the switching time difference is too small for the user's eyes to detect. When the activity is rebuilt, just before the previous activity is destroyed, the system will call onSaveInstanceState (Bundle outState) to store various states at that time. In the new activity, Android will read the data through onRestoreInstanceState (Bundle savedInstanceState) and automatically restore to the View of the previous activity. Of course, in the activity, the developer's own code logic needs to be processed by himself.
