In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).

Abstract Factory: Creates a series of interdependent objects and can change the series at runtime.
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.
