TCB (TCP? Transport Control Block is a transport protocol data structure that contains all the information of the connection (in fact, in many operating systems, it is a queue used to process inbound connection requests. The queue holds TCP connection items that are in a half-open state and items that have established a full connection but have not yet been extracted by the application through an accept () call). The amount of memory occupied by a single TCB depends on the implementation of TCP options and other functions used in the connection. Usually a TCB has at least 280 bytes, which in some operating systems has exceeded 1300 bytes. The SYN-RECEIVED state of TCP is used to indicate that the connection is only half open, and the legality of the request is still questioned. An important aspect worth noting here is that the size of TCB allocation space depends on the SYN packets received-before the connection is fully established or the return reachability of the connection initiator is verified.
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.

《生活大爆炸》的执行制片人Bill Prady日前透露了一些关于第五季Penny将会有什么经历的细节。 这部CBS热门情景喜剧的第五季将于金秋回归。上一季以Penny和Raj的酒后一夜情作为大结局，多么坑爹的悬念设计呀！ Bill Prady 向TV Line解释道：“Penny的服务生事业前途渺茫，现在她身边只有这群好朋友了，结果她还跟Raj乱爱了一回，破坏了这种关系。” “在她的一生中，这是第一次有把她当做真正的人并且尊重她的男性朋友，而不像以前那些男人只是把她当做调情的对象。可惜她这回又搞砸了，不知朋友还有没有的做。” Prady承认自己喜欢看着剧中人物的生活搞得一团糟，然后他们再努力挽回的过程，他还说道：“对于Penny来说，这将是个非常有趣的经历。。有时候安排他们把事情搞砸，甚至彻底悲了个剧，之后再看他们如何跳出困境真是特别好玩儿的！” 他还透露说在剧中饰演Howard女友Bernadette的演员Melissa Rauch将会继续出演这部喜剧。 Prady曾向TV Guide透露：“关于Howard婚礼的各项事宜都将在新一季中上演，包括伴郎和伴娘的人选。婚前的单身派对将是个悲剧，但是最难得是Howard如何从老妈那里搬出来。” 之前还有消息称Leonard在第五季中跟Priya会来场相隔半个地球的异地恋。 《生活大爆炸》在今年1月份时已经获得了未来三季的预定，因此至少会播出到第七季。 《生活大爆炸》第五季将于今秋9月22日（周四）晚8点回归，而且是两集连播。
