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.「请叫我英雄：开战之日」全世界人类被神秘病毒“ZQN”大量感染、电影「请叫我英雄」的前传。长泽雅美扮演“庸医”小田つぐみ、本sp是她还是护士时候的故事。　　这部剧由《美国众神》作者尼尔·盖曼与《碟形世界》作者特里·普拉切特所著的同名幽默奇幻小说改篇（该小说名称是恶搞恐怖电影《凶兆 The Omen》）。 两位作家斩获了二十余次奇幻文学的头等大奖，写《好兆头》却只是为了让对方大笑出声。原著功力可想而知。吴环宇被安排去接替父亲参与管理企业，却整日沉迷电子游戏，母亲杜茗一气之下将他轰出家门，开始了流浪生活。杜茗暗中安排网络高手与他在网上较量，吴环宇输掉游戏，只能答应对方去打工，杜茗无论在生活上还是生意上处处与他做对，将吴环宇逼向绝境，却逼出吴环宇淘到了第一桶金。杜茗输了，却用自己的智慧换来儿子的成熟。Qinglan told Hexin that this was the last time he came to see him.
