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.众人听呆了。做的不错，破甬道降苏角，大功一件。剧情简介：KenP饰演的奴隶和Bella饰演的贵族小姐尽管身份悬殊，但彼此深爱着对方，两人常常在岸边约会。不久，这件事被女主的父亲发现了，女主的父亲派男主出去并暗下杀手，而且还为女主安排了婚事。另一方面，以为男主死了的女主万念俱灰，在他们经常约会的河边自杀，幸好男主及时出现，救下女主……最终两人能否在一起呢？她右手紧紧捂在胸前，那儿有个硬硬的小东西——葫芦哥哥送她的小葫芦。　一个受尽白眼的街头混混（陈创 饰），一个遭到排挤的转校生（郭可轩 饰），孤独失意的两人，在一系列意外中，成为了彼此唯一的朋友。然而生活给了他们不同的难题，当夏天结束的时候，他们的友情似乎也走到了尽头……　　虽然彩身体上有残障，但她水晶般纯净的心灵也打动了秀一。秀一鼓励她说总有一天星星会像童话故事里写的那样，落在她的身上。两年后，秀一要回东京了，在登机前，他承诺彩会很快回来娶她。
