If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. The end result is that the server has no time to ignore the normal connection request-denial of service. If you look at the SYN_RECV status on the server with the netstat-an command, you can see that there are a large number of connection states that are "SYN_RECEIVED"
Avoid coupling the sender and receiver of the request, make it possible for multiple objects to receive the request, connect these objects into a chain, and pass the request along this chain until an object processes it. This is the responsibility chain mode. In the responsibility chain mode, it is possible for each object to process the request, thus realizing decoupling between the sender and receiver of the request. At the same time, the responsibility chain mode simplifies the structure of the object, which makes each object only need to refer to its successor without knowing the whole chain, thus improving the flexibility of the system and making it more convenient to add new request processing classes. However, we cannot guarantee that all requests can be processed in the responsibility chain, and it is not conducive to observing runtime characteristics.

毛骗，意思是指街头的小毛骗子，他们有组织有纪律，混迹在城市的边缘。他们是骗子，是侠盗，是不法份子，或者他们没有高尚品德，但是有职业操守，他们的目的不仅仅是为了钱。他们是高智商的艺术家，精密算计着每一步的计划，锁定目标，制定计划，精心布局，诱敌深入，最后把贪婪好色和为富不仁者收入网中。小偷看不起强盗，因为强盗没有技术含量；骗子看不起小偷，因为小偷没有艺术含量。每一件事，只要到了极致，就是一种艺术。这是一面镜子，反映社会的另一个层面。有些东西也许我们都看不到，但是我们都听说过，这是当下的故事，未来的传说。此为毛骗第二季。
