The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.

(2) The client side initiates a connection request to the server side, and the Reactor listens to the occurrence of the ACCEPT event and sends the ACCEPT event to the corresponding Acceptor processor for processing. The Acceptor processor obtains the connection (SocketChannel) corresponding to this client through the accept () method, and then registers the READ events that the connection is concerned about and the corresponding READ event handler with the Reactor, so that the Reactor will listen for the READ events of the connection. Or when you need to send data to the client, register the WRITE event for the connection and its processor with Reactor.
