DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.公元前52年，罗马共和国正值鼎盛时期，执政官庞贝（里克•沃登 Rick Warden 饰）坐守都城，盟友凯撒（塞伦•希德 Ciarán Hinds 饰）征战高卢。期间，第13军团屡立战功，主将乌里纳斯（凯文•马克德 Kevin McKidd 饰）有勇有谋，手下波罗（雷•史蒂文森 Ray Stevenson 饰）虽嗜酒如命，却忠肝义胆。适逢凯撒得胜，屋大维遵母命赴前线慰问，不想途中遭劫，被经过的乌里纳斯和波罗救下。13军团凯旋，乌里纳斯与阔别8年的妻子相见，却各怀心事。波罗偶然间发现了乌里纳斯妻子红杏出墙的事实，为了保护长官的名誉，波罗在屋大维的帮助下，逼出了真相。凯撒准备独揽大权，一直等待时机。庞贝看出了他的野心，与元老院众人商议，其中以西塞罗为首的贵族势力，坚持认为凯撒为共和国叛徒，应诛杀之。而此时，凯撒的大将安东尼（杰姆斯•鲍弗 James Purefoy 饰）接任了护民官，与庞贝一伙展开周旋……Resource confrontation is also called "dead shoulder", that is, through the piling up of a large number of servers and bandwidth resources to achieve the effect of calmly dealing with DDoS traffic.以前，他娘郑氏总喜欢跑去看，说是与别处的花不同。这是一部浪漫的历史剧，基于第一个女人“征服者”的真实故事，她去了南美洲的土地，也就是后来的智利，并帮助建立了圣地亚哥市。它是根据伊莎贝尔阿连德2006年的小说改编的。
