A game played according to basketball.When the server provides some UDP-based services, such as DNS, SMTP, NTP, etc., and finds some requests, in which the Response message is larger than the Request message, the Attacker sends a Request message that forges the source IP, and the source IP forges the IP address of the victim. After receiving the Request message, the server replies the "enlarged" Response message to the victim, thus realizing the amplification of traffic. The principle is roughly as follows:Chapter V Legal LiabilityThe attack uses the method of sending a large number of domain name resolution requests to the attacked server, Usually the domain name requested to be resolved is randomly generated or does not exist on the network. When the attacked DNS server receives the domain name resolution request, it will first look for whether there is a corresponding cache on the server. If it cannot be found and the domain name cannot be directly resolved by the server, the DNS server will recursively query the domain name information from its upper DNS server. The process of domain name resolution brings a great load to the server. If the number of domain name resolution requests exceeds a certain number per second, the DNS server will time out to resolve domain names.All printed boards must be marked with the printed board number, the company logo, the design date and the manufacturer's production date (marked by year and week).　　又到1999年除夕，笃志的心脏病在同一时刻再次发作，当他醒来的时候，再次回到1995年，开始了重复的人生。该剧是讲述被认为是杀人事件嫌疑人的韩国顶尖主播高惠兰（金南珠饰）和她的律师丈夫姜泰旭（池珍熙饰）所相信的爱情的真谛的激情爱情悬疑片。接档《Untouchable》于2月2日首播。
