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.　　母亲早早就为蒙泰定下了门当户对的亲事，对方是娇蛮千金大小姐薇雅（Panward Hammanee 饰）。一次偶然中，碧雅因为采摘无忧花而遭到了薇雅的无情打骂，就在此时，蒙泰出现救下了碧雅。之后，机缘巧合之下碧雅成为了薇雅家里的女佣，随着时间的推移，她和蒙泰之间逐渐产生了感情。变质的爱[泰剧]项羽应该很需要这样一支兵力在大河之北帮助他牵制韩信，抵御汉军。故事以抗战时期桂林土生土长的戚家和苏家两家人命运展开，随着中国抗日战争的全面展开，戚家四兄弟与苏家三姐妹之间也随之上演了种种曲折和复杂的情感纠葛和命运变化
