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.张静是广告公司的职员，因为广告方案改了多次仍未通过而着急气晕了过去，没想到穿越到古代一个大户人家的大小姐林清儿的身上。林清儿因为身材原因，在家中处处受气，自己的妹妹也要欺负自己。张静既然穿越，便想帮助林清儿找回自信。开始盘算着如何赚钱，连富可敌国的城主儿子陈墨的提亲也爱答不理。陈墨是骄纵的公子哥，没想到有人对自己敢说不，便开始疯狂追求林清儿，不惜花重金与她见面。林清儿根本没想与陈墨的感情，一心只想搞钱，甚至利用陈墨对她的感情。陈墨越得不到便越想得到，这也引来了林平儿的嫉妒。Source: Brother Guo蕭正楠、曹永廉飾演明朝武官文官，何廣沛 飾演小太監，蕭正楠飾演的明朝將軍穿越到現代尋找公主，鬧出不少笑話。马大姐原单位的一位老姐妹在退休前光荣加入了中国共产党。她特意来把这个喜讯告诉马大姐，因为想当年二人是同期参加工作的，而且又一起写过第一份入党申请书。马大姐既为老姐妹高兴又为自己伤感，觉得提前退休使自己的政治生命也早早结束了，现在她这样一个闲人哪有资格再提入党的事呢?为此她几天闷闷不乐，突然接到去街道办事处开会的通知。原来马大姐所在的街道开发了一个便民小旅馆，因一时找不到合适的负责人选，便想起了马大姐。因为她退休前曾在国务院招待所工作多年，所以被聘为临时代理。马大姐对自己在有生之年还能为社会做贡献感到非常振奋，觉得可以在新的工作岗位上接受组织上的考验，入党还是有希望的。便在上班的头天晚上写了入党申请书。可没想到旅馆刚开始试营业就出了不少麻烦，马大姐按倒葫芦起了瓢，还得罪了不少来沾光的老邻居。更要命的是她不知道自己刚上任就已结下了冤家对头一一办事处会计老徐其实很想当小旅馆经理，没想到让马大姐占了这个位置，他只是受上级派遣定期末做财务督察。老徐表面上热心地给马大姐支招。暗中却在找她的毛病，准备
