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.若是不行，便趁夜晚决堤放水。该剧以中国共产党历史上具有重要意义的第七次全国代表大会为历史背景，通过几个小人物独特的视角来重现党史上那个伟大辉煌的历史瞬间。本剧的几个主人公都是正值青春年华的年轻人，发生在他们身上的故事和他们的命运都与“七大”的召开紧密相连。在他们当中，有人当了“七大”代表，有人成为“七大”筹备处秘书处的工作人员，也有人成为八路军特别支队的支队长，肩负着穿越敌人的一道道封锁线，掩护各抗日根据地的重要领导和“七大”代表们安全抵达延安的重任。在与日伪和国民党特务企图破坏“七大”的斗智斗勇的战斗中，他们无私地献出了自己的青春和热血，有的人甚至为“七大”的胜利召开献出了年轻的生命。几个北漂女孩作为一个女子跳唱组合，共同追逐梦想，不断成长的故事。 她们因梦想相识，因努力相知，从最初的一盘散沙，到后来的同心协契，团结一致。《台湾第一等》为大家发掘台湾的最新奇有趣,最出名及最有特色的人和事。在台湾长大的节目主持人小马,用台湾人的角度,探索和纪录最真,最特别的台湾。
