Abstract


Suppliers ) , ICP ( Internet content provider ) , security and operational challenges faced by IDC ( Internet Data Center ) and other carriers also growing , operators must DDos threat before impact critical business applications , traffic detection and cleaning , to ensure normal and stable network operation as well as the normal conduct of business . Of the DDos attack traffic detection and cleaning can become a value-added service operators to provide users with better user satisfaction . DDos the essence is to use a variety of service requests system resources depleted attack network so that the network can not handle the request of the legitimate users being attacked . If you can reduce or even suppress the request sent by an IP source selectively discard packets from the source IP , you can reduce network traffic , network traffic control less than a certain threshold to ensure server health stable operation , effective defense DDos attack . For DDos defense of the industry is also thought to carry . Involved in the abnormal flow cleaning management system consists of a total of three parts: part abnormal traffic detection equipment the Probe, abnormal flow cleaning equipment Guard as well as abnormal flow cleaning business management platform that flow cleaning management system , which is this article highlights . Once a DDOS attack or device status change , the system is able to timely obtain abnormal situation , generate alarm information and timely notification of relevant personnel for processing . The Probe, Guard and systems through the SOP protocol, UDP protocol , such as communication and interaction , and thus form a unified whole . Abnormal traffic detection equipment and abnormal traffic using the industry-leading \The system according to the specific circumstances of the network , configure the appropriate threshold for the abnormal traffic detection equipment attributes and the corresponding operating instructions issued time monitoring network traffic trends . Once DDos threat , immediately notify the abnormal flow cleaning equipment and quickly filter the attack traffic , in order to effectively protect the MAN IDC ( Internet Data Center) from massive DDos attack , making the protected server normally stable and sustainable provide services.
