As mentioned above, SYN attacks can be prevented by increasing the backlog queue. In addition, reducing timeout time also enables the system to process more SYN requests. We know that the timeout timeout, that is, the half-connection lifetime, is the sum of the timeout times that the system waits for all retransmissions. The larger this value, the longer the half-connection takes up the backlog queue and the fewer SYN requests the system can handle. In order to shorten the timeout time, it can be realized by shortening the retransmission timeout time (usually the first retransmission timeout time) and reducing the number of retransmissions.当Mark得知来自医学院的Kit很难接近时，他打算挑战Kit医生。但是，在他与医生见面的第一天，他就陷入了对Kit不利的一面。他一直在追求医生，当他有信心要求Kit成为他的男朋友时，同时发生了一些事情，结果Kit没有接受Mark的爱。所有人都感到失望。问题解决之后，Kit和Mark决定调整他们的理解。Iron Painting and Silver Hook is a high damage skill, High damage depends on the gun soul, and it should be noted that five consecutive sweeps can be superimposed on two layers, specifically the second sweep, and the fifth sweep will be superimposed once each. It is suggested that five consecutive sweeps and then three consecutive stabs can be superimposed on three layers of gun soul in 5-6 seconds. At this time, the cooling of this skill has not been completed, so the skill of boss is required.眼前浮现王穷的面容，她不禁犹豫了。Code as above; Write three functions of order500, order200 and orderNormal respectively, and process their own business logic in the functions respectively. If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.小驯鹿尼科梦想着能和从未相见的驯鹿爸爸一样成为会飞的圣诞驯鹿。尽管有很严重的眩晕，尼科还是每天偷偷溜出它所住的山谷，花大部分时间向罕见的芬兰飞行松鼠家族成员Julius学习飞行课。
