The most basic defense at the network layer is RFC? 2827 [3]. Using input source filtering, ISP refuses to route a packet whose source IP address does not belong to its source subnet further. Input source filtering can effectively prevent SYN flooding attacks disguised as IP. However, this method is useless at present because it is difficult to deploy on a large scale. Moreover, input source filtering cannot resist distributed attacks.
1997 年秋天，迈克尔·乔丹和芝加哥公牛队开始了他们八年来第六个 NBA 总冠军的追逐。但是，尽管乔丹自 13 年前大放异彩以来取得了非凡成就，但主教练菲尔·杰克逊称之为“最后的舞动”的这次比赛被俱乐部高层中的紧张气氛所笼罩，因为这是最后一次看到有史以来最伟大的球员和他杰出的队友们一起奋力拼搏。

Fires cause huge losses to people's lives and property in our country every year. The application of flame retardant fabrics can effectively delay the spread of the fire. Especially in public places, the use of flame retardant fabrics can avoid more casualties. The difference between flame retardant fabric and ordinary fabric is that it can reduce the burning speed of textile materials to different degrees and stop burning quickly after leaving the fire source, which can reduce fire accidents caused by textiles and avoid unnecessary losses.

The above is only a model of "Long En" bicycle, If you need to generate other types of bicycles, Other subclasses can be written. The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.
