According to China's first "Chinese Domain Name Service and security status Report", China's more than 50% of the domain name server is relatively insecure, 57% of the important information system exists the risk of domain name resolution, only in 2010, domain name hijacking, domain Name Service server frequent paralysis and other domain name security incidents as many as 10. As the basic address resource support of Internet application, the security risk of domain name will be far-reaching, which will lead to the total paralysis of the network and endanger the national information security.

The National Development and Reform Commission in 2008 specifically launched the "Cngi trusted domain Name Service System Industrialization Project", committed to building the next generation of Internet services capabilities of the domain Name System, and the project technology achievements to achieve industrialization. After two years of research and development, the project "Broken Cocoon into Butterflies", the successful "hatch" out of this set of Zdns domain name resolution series of equipment.

It is understood that this set of Zdns series of equipment can be for the vast number of operators, domain Name service providers, large Web sites to provide complete, professional, highly credible and can be "tailored" domain name resolution server, including authoritative domain name resolution server and recursive domain name resolution server, is currently the industry's most functional, performance of the most outstanding domain name resolution equipment, In the domain name resolution security and convenience of the obvious advantage.

The following is a description of the performance metrics for three devices, and am because the focus is on data analysis and presentation capabilities, so the indicators are not listed. Zdns-a supports up to 1 million zone files based on session-by-Region file transfer technology, which reduces delivery times by 97% to support up to 1 billion resource records compared to bind; processing capacity: 120,000 QPS, twice times zdns-r processing capacity for bind: 100,000 QPS, 1.5 times times zdns-d support for bind 900,000 QPS100 million black and white list and statistic list flow control precision can reach 1%
