The fundamental reason for using design patterns is to adapt to changes, improve code reuse rate, and make software more maintainable and scalable. In addition, the following principles should be followed when designing: single responsibility principle, open and closed principle, Richter substitution principle, dependency inversion principle, interface isolation principle, composite reuse principle and Dimit principle. Each design principle is described below.

Director and actor Mark Webber explores family dynamics using his real family as the cast and real-life situations for the story to create a film that authentically blurs the line between narrative and documentary. "Flesh and Blood" tells the story of Mark, a man returning home from prison to live with his mother and teenage brother in the inner city of Philadelphia. Attempts to rebuild his life become frustrated by struggles with sobriety, a strained relationship with his activist mother, the neglect of a teenage brother with Asperger's and a rehashed cycle of abandonment by addict fathers. A dysfunctional family tree soon emerges whose every branch is not only broken but likely unrepairable.

In addition to solving the port problem of A, the serial number problem also needs to be paid attention to. The serial number corresponds to the sliding window. The fake TCP packet needs to be filled with the serial number. If the value of the serial number is not in the sliding window of B when it is sent to B before A, B will actively discard it. So we need to find the serial number that can fall into the sliding window between AB at that time. This can be solved violently, because the length of a sequence is 32 bits, and the value range is 0-4294967296. If the window size is like 65535 under Windows I caught in the above figure, I only need to divide, and I know that at most I only need to send 65537 (4294967296/65535=65537) packets to have a sequence number fall into the sliding window. The desired value can be calculated quickly by exhaustion on multiple control hosts.

Is it TCP to try to send enough SYN packets and run out of backlog? The purpose of SYN flooding. 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.

Different from the single-threaded Reactor mode, a worker thread pool is added and non-I/O operations are moved out of the Reactor thread and transferred to the worker thread pool for execution. This can improve the I/O response of the Reactor thread without delaying the processing of subsequent I/O requests due to some time-consuming business logic.
