In the process of DNS resolution, the client initiates a query request, and the DNS server may need to make additional queries to complete the resolution process and give a response, which will consume certain computing and network resources. If an attacker uses a large number of controlled hosts to continuously send resolution requests for different domain names, the cache of the DNS server will be continuously refreshed, and the failure of a large number of resolution requests to hit the cache will cause the DNS server to consume additional resources for iterative queries, which will greatly increase the resource consumption of the DNS server.

SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

这部剧集是否在影射现实生活中的Tom Cruise（汤姆-克鲁斯）和Katie Holmes（凯蒂-赫尔姆斯）？是否在影射山达基教（科学教派）？制片人对此问题的答案永远一致：别胡说八道！E!频道甚至发了一份官方声明来澄清事实：该剧纯属虚构，并不针对现实生活中的特定人物。《缚爱之约》是E!频道继《王室》（The Royals）之后的第二部原创剧集。该剧描述了一个以好莱坞为背景的现代灰姑娘故事，主人公Megan Morrison（Christine Evangelista）是一位年轻美丽的女演员，正在角逐一部夏季大片的女主角。如果她拿到这个角色，将与当红男星Kyle West（Josh Henderson）——「当代美国最帅动作电影明星」——演对手戏。Megan的试镜非常成功，并且很快与Kyle有了一次梦幻般的初次约会，但她很快意识到这是一个陷阱——她必须签署一份协议，她与Kyle的关系的所有细节在其中都有详细描述。Megan必须小心做出选择，因为这些选择既可以给她带来好处（让她成为童话中的灰姑娘），也可以给她的事业造成严重后果……甚至毁掉她的人生。她是否应该接受这份「协议」呢？
