In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.在江户时代×科学搜查的组合下诞生出穿越推理的新世界：在现代过着普通生活的女性，一边自由地穿梭于现代与江户之间，一边运用科学技术向江户时代的棘手案件发起挑战。化身“阿优”的关口优佳是否能够披荆斩棘，最终找到真相呢？这是一间营业时间从午夜十二点到早上七点的特殊食堂。这里的老板，不太爱说话，却总叫人吃得热泪盈眶。在这里，自卑的舞蹈演员偶遇隐退多年舞界前辈，前辈不惜讲述自己不堪回首的经历不断鼓舞年轻人，最终令其重拾自信；轻言绝交的闺蜜因为吃到共同喜爱的美食，回忆起从前的友谊，重归于好；乐观的绝症患者遇到同命相连的女孩，两人相爱并相互给予力量，陪伴彼此完美地走过了最后一程；一味追求事业成功的白领，在这里结交了真正暖心的朋友，发现真情比成功更有意义。食物、故事、真情，汇聚了整部剧的主题，教会人们坦然面对得失，对生活充满期许和热情。每一个故事背后都饱含深情，情节跌宕起伏，令人流连忘返。本片根据日本同名日剧翻拍而成。最重要的问题是，Rae Earl刚从一个特殊的地方回家——精神病院。但她答应了自己和妈妈一切都会好起来，她要勇敢的对面生活的爱情。究竟这个胖妹会带来一段如何经常的生活日记呢？[1]面对中国加入WTO后很多领域与国际接轨的新形势，家境贫寒的严达明（刘涛饰）通过不懈的努力，将一个小小的公司发展成为拥有上亿资产的跨国集团公司，在这之中，他经历了创业的风风雨雨，经历了生活、感情的创痛。他和公司的全体成员齐心协力，立足于本国，立足于大连，开拓思路，努力开创自己的事业，为扭转国有企业亏损局面、为下岗职工恢复工作而呕心沥血；他建立集团公司融资发行股票，引进高科技项目发展我国的自主工业；他与走私犯罪集团坚决斗争……他在创业生活中深深地认识到：一棵大树之所以枝繁叶茂，是因为它的根深深地扎在祖国的土壤之中。Home OperatorDDoS attacks can be divided into heavy traffic attacks, TCP state exhaustion attacks or application layer attacks. In Kapersky's DDoS Attack Report published in the second quarter of 2011, HTTP flood attack is the most common DDoS method, which is an example of application layer attack. The dominance of application layer attacks reflects that the rapidly evolving DDoS has broken away from the traditional direction of large traffic attacks.
