Source authentication and resource isolation, that is, when the client and the server establish a reply, the source of the request is authenticated as necessary, and the authentication results are formed into a reliable white list or blacklist, thus ensuring the effectiveness of the server in processing services. If there are enough hackers and broilers and the authenticity of forged data packets is high, a better countermeasure effect can only be achieved by improving the processing speed and traffic throughput of the server.Sourceable source1 = new SourceSub1 ();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.三人跟着脚印，发现很多奇诡的事情，鞋印居然飞上三米高的墙头。一跃三米高，这是什么人？脚印居然跃过七米远的沟壑，闽玥越发觉得诡异。三人费尽心血奔波，跟着脚印走到一个小山谷，三人，一只大雁正挣扎着啄开脚上的大鞋子。三人明白自己被耍了。陈启可以不需要思考，直接把脑海中的内容，敲击出来就行了，别说是吕馨，就算任何一个高速度作者来了也不行。View the new image for the v5 version:You may also like:
