Preface Sharing:If an attack is detected, the management center will start a cleaning scheme to pull the mixed traffic of attack traffic and normal traffic through BGP, CDN, etc. Pull the mixed flow to the flow cleaning center for cleaning. The problem in the process of traffic cleaning is that the current DDOS attacks present a mixed attack state with multiple attack methods coexisting. In this case, how to efficiently detect attacks is the main problem currently facing. After consulting numerous data, Huawei's "seven-layer cleaning plan" is found to be very enlightening. The scheme comprehensively analyzes data packets for mixed traffic through seven layers of defense measures such as static filtering, abnormal message filtering, scanning and snooping message filtering, source legitimacy authentication, session-based prevention, feature identification filtering and traffic shaping, so as to detect attack traffic to the greatest extent. The framework of Huawei's "seven-layer cleaning scheme" is shown in Figure 2. After the traffic is cleaned, the attack traffic is discarded, and the normal traffic is injected back into the network through MPLS, GRE tunnel technology, etc.Unicom这是一个影响历史的千年商帮。 这是一段以商事国的壮阔史实。 这是一首面向世界的时代赞歌。 大型历史文化纪录片《秦商》遵循“树立文化自信、文化强国”国家战略，以大气恢弘的手笔，贯穿五千年中国商业历史，寻觅秦商以及中国传统商业文明的足迹。纪录昨日秦商以商事国、以商兴国的历史故事，感召今日新时代中国商业文明的再度崛起。 秦商纵横中国历史五千年，一部秦商的历史也就是一部中国商业社会的历史。《秦商》以恢宏的格局、独到的视角，全景展现了秦商这一中国历史最为悠久的商帮千年来的发展历程。尹旭年纪轻轻，身上所散发出的气势让人忍不住的折服。Erythrina Park is located on the northwest side of the intersection of Erythrina Road and Jinhuai Street in Fengze District of Quanzhou City.
