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.The main target of link attacks is the link bandwidth resources on the backbone network, and the attack process is roughly as follows同治三年（公元1864）太平天国作乱，福建省骠骑将军林文豪连年争战杀场，趁着回台空隙探望妻儿，不料竟撞见其妻宝霞因不耐长年忍受丈夫不在身边的孤独，决心与文豪多年好友朱士贵私奔，林文豪几经挣扎，决定放宝霞走，往后孤独一人带着女儿林玉环在战场上杀长毛军报效国家。本剧讲述了在哈尔滨的一条百年老街——中央大街上，一群青年男女因缘分而结识，他们在这里一起分享，一起成长，帮助步行街上的”过客“解决了不少问题，同时也给这条街道带来无数欢乐和感动……Discussion expert影片剧本来自宙比·哈罗德，该剧本基本忠实于托马斯·马洛礼15世纪的文学作品《亚瑟王之死》，剧情颠覆传统，一路探索亚瑟从市井到王座的征途。亚瑟的父亲在他小时候就惨遭杀害，亚瑟的叔叔伏提庚篡取王位，剥夺了亚瑟的天赐之权。他浑然不知自己的身世，在城市的穷街陋巷里摸爬滚打着长大，但当他拔出石中剑，他的人生就彻底地天翻地覆了，亚瑟不得不接受自己真正的使命。周游神户港的游览船突然发生爆炸，犯罪者以船上的乘客作为人质，向该船的所属公司“黑泽兴产”勒索两亿日元。偶然在场的警视厅月岛署刑警系村（上川隆也），以不经意间发现的一张纸片为线索介入了这起事件。
