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.The second classification principle of organisms is the lineage classification principle aiming at establishing evolutionary lineage. The classification method following this principle is called lineage classification. The representative of pedigree classification is "branch systematics". It advocates that the branches in evolution should be taken as the criteria for identifying and distinguishing classification units and the basis for determining the pedigree relationship of each classification unit. The so-called co-ancestral proximity (similar to a group of people being a grandfather) is used to measure the genetic relationship between different taxa and determine their position in the pedigree. The classification system finally established is an evolutionary pedigree reflecting the history of phylogeny, which is a deeper description of biological relationship. In other words, the basic principle of pedigree classification is that the classification system conforms to the evolutionary pedigree. Pedigree classification is only applicable to organisms and cannot be used for abiotic classification.The JSON text format is syntactically the same as the code that creates JavaScript objects.
