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. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.对永堂的二个女人来说，他爱的那个《有情无份》，爱他的那个《有份无情》。既然“爱情”给了玉芳，能给丽淑的就只有“名分” 得到“名分”的丽淑，在忍受寂寞后，仍梦想拥有老公的“爱情” 得到“爱情”的玉芳，竟不时暗自垂泪，只因“名分”是那么遥不可及……优柔却也负责任的个性，注定了大老婆、小老婆之间的这二个家庭,一辈子说不清的矛盾与纠葛……Here, the event is bound to the created fakeElement, then the event trigger is simulated (the event handler in this example is executed), and then the event binding is unregistered.Speed up and increase connections: Through a large number of repeated deliberate exercises, experts are much faster than beginners in the coding and extraction process, increasing various channels between long-term memory and working memory.《唐突的女子》讲述了本来是小姑子和嫂子关系的两个女人，变成儿媳和婆婆关系而发生的一系列故事。
