Amplification attack is a special reflection attack. The special feature is that the reflector has the function of amplifying network traffic and is a common technical means in DDoS. Its basic principle is relatively simple. For a C/S service, if the Server-to-Client Response message is larger than the Client-to-Server Request message, the traffic is enlarged.

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.Ctrl + K: hyperlink兰欣（蒋欣 饰）把建设社会主义新农村作为人生追求，嫁给了青年农民吴家义（程皓枫 饰），最终在农村安家扎根。几年后在村委会主任、丈夫的姑妈吴雪梅（黄晓娟 饰）的帮助下，准备参选新一届村委会主任。就在这个时候，家庭突遭巨大变故，兰欣和吴雪梅对已达到小康的白河村的未来发展计划产生激烈冲突，丈夫为了离开农村要和兰欣离婚。吴雪梅将兰欣停职，直至将其赶出白河村。在如此艰难的困境中，完全可以回到大城市开拓新生活的兰欣顽强地坚持下来，并最终为她热爱的白河村闯出了一条新的发展道路。
