SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.项羽上次辱及自己，这一遭也要尝试着找回面子，打回这一巴掌，而且还要打的分外响亮。In fact, what two people give each other together should be to let you get up happily and fall asleep at ease every day.

If the size of the TCP window is 0, it means that the accept buffer has been filled and the sender should stop sending data until the window on the receiver is updated.At the beginning of this year, Osaka Weaving House cut off the Electronic Commerce Department and Wang Bo led the establishment of a new Tmall retail division covering the backbone of various departments.
