When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.

However, Jiang Min, vice president of the Real Education Fund, said that due to the high investment cost of offline institutions and geographical restrictions on their development, it is more optimistic about online education. At present, besides children's English, the demand for thinking ability training is very large and the market facing it is also wider. "Children's English has explored a relatively mature online development model, and their thinking ability can be used for reference. Moreover, users' acceptance of online education products is increasing day by day. It is relatively easy to start the market for education, and there are more talents who know the operation and management of online education. In addition, the cultivation of children's thinking ability pays more attention to the thinking process, and the requirements for expression and communication are relatively weak, and the demand for one-on-one teaching is relatively low. The cultivation of online thinking ability is likely to accelerate faster than the development of online children's English. "

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.
