唐伯虎神情凛冽，用着没有枪头的枪，迎向夺命书生。就放到屋子里吧，依兰芳香。　　Freya最近刚刚和梦中情郎、富有的花花公子Dash Gardiner（Eric Winter）订婚，但她同时对Dash的兄弟Killian（Daniel DiTomasso）很有好感……或许因为Killian是个谜一般的坏男孩。可是她与Killian靠得越近，就越感觉诡异：一些令她无法想象的事情接二连三地发生了。Half-connection survival time: refers to the longest survival time of entries in the half-connection queue, that is, the longest time from receiving SYN packet to confirming that this message is invalid. This time value is the sum of the longest waiting time of all retransmission request packets. Sometimes we also call the half connection survival time Timeout time and SYN_RECV survival time.Suppose the attacker is in an "interconnected" network (e.g. An Autonomous system? System), whose ISP restricts the input and output filtering of the attacker's network traffic, will be able to prevent this spoofing attack-if this method can be deployed to the correct location by the organization. This defense method of traffic input and output filtering will restrict some legitimate communications, such as the mobile IP triangular routing operation mode, so it cannot be widely deployed. IP Security Protocol (IPsec) also provides an excellent way to resist spoofing packets, but this protocol cannot be used due to deployment restrictions. Since it is usually impossible for the server side to require the ISP of the link initiator to implement address filtering or require it to use IP security protocols, more complex solutions are needed to resist this spoofing attack disguised as multiple addresses, which will be discussed later.218.
