The attacker added the source IP address to the SYN packet, which would not cause the host to remove the assigned TCB from the SYN-RECEVIED state queue (because the host would respond to the SYN-ACK). Because TCP is reliable, the destination host will wait quite a long time before disconnecting the half-open connection and removing the TCB from the SYN-RECIEVED queue. During this period, the server will not be able to respond to legitimate new TCP connection requests from other applications. Figure 2 shows a simple TCP? The process of a SYN flooding attack.MDT core members are required to participate in all cases that require their participation in the discussion;IP is an abbreviation of Internet Protocol in English and "Internet Association" in Chinese, which is also a protocol designed for communication between computer networks. In the Internet, it is a set of rules that enable all computer networks connected to the Internet to communicate with each other, and stipulates the rules that computers should abide by when communicating on the Internet. Computer systems produced by any manufacturer can be interconnected with the Internet as long as they abide by the IP protocol.

For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.任清泉是香港知名的书画家，在上环开设了一家卖文房四宝兼卖名家书画的店铺“多宝轩”。为了推广中华文化，还开班教授书法和国画。清泉妻子早丧，多年来与妻舅高大威和女儿芝华一同生活。芝华在北京完成了美术课程返回香港，这个慈父显得特别着紧，花尽心神为女儿打点一切。为了女儿回家，清泉快活了大半天。他说：“我一定要为女儿做一点事，否则我的心总是耿耿于怀。”这段父女关系，似乎有不为人知的内情……方子聪是IT界的青年才俊，终日和时间竞赛，令他的脾性也有点急躁。唯独他对母亲慧玲感情特别深厚，事母至孝，是母亲眼中的宝贝乖仔。子聪偶然机会下认识芝华，却误会芝华是个见死不救的人，从此对芝华毫无好感，芝华却似有难言之隐，有苦自己知……
