板栗就道，他睡过头了。Https://www.jiemian.com/article/1911363.htmlAlthough this kind of attack has appeared for 14 years, its variants can still be seen today. Although technologies that can effectively combat SYN flooding already exist, there is no standard remedy for TCP implementation. You can find different implementations of different solutions to protect the application layer and network layer in today's operating systems and devices. This paper describes this attack in detail and looks forward to and evaluates the anti-SYN flooding methods currently applied to end hosts and network devices.Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:当悲剧发生在斯德哥尔摩最富裕郊区的一所预科学校时，一名普通高中生马亚·努尔贝里发现自己因谋杀罪而受审。当那天的事件被揭露时，她与塞巴斯蒂安·法格曼的关系，以及他那不正常家庭的私密细节也被揭开了。《流沙》（Störst av allt）改编自马林·佩尔松·焦利托的畅销小说，该书在 26 个国家/地区出版，并被评为“2016 年北欧年度犯罪小说”。Let's look at Window's source code:…,怎么？钟隐笑问道：难道项羽现在也不放心英布？尉缭道：如果英布和我们打起来了，那项羽和范亚父自然没什么担心的，但是现在没打起来，担忧也是情理之中的事情。
