Problems solved by technology

We are very passive in the prevention of this type of problem, but at present, it is difficult to expand the cooperation of the root domain name server, and the problems caused by attacks, hijacking and other problems will cause large-scale paralysis of DNS resolution and cannot respond.

Embodiment 1

[0047] 1. Basic data collection layer

[0048] The basic data collection layer mainly implements the collection function of DNS data traffic. The data sources are subdivided into three channels: one is to keep in sync with the foreign root domain name system; the other is to deploy the equipment at the international outlet to collect the export traffic; the third is to deploy it side-by-side on the DNS server of the provincial operator to collect user request data. The first method uses the full and incremental zone transfer mechanism. The second and third are collected by mirror copying.

[0049] 1. Root and top-level domain data acquisition

[0050] This part is based on DNS-related protocols. Through the regional transfer mechanism, the international root and top-level domain data are completely replicated, providing support for the platform service layer to realize the recursive analysis service of root and top-level data. When a new DNS server is added to the network a...

Embodiment 2

[0093] Two high-performance DNS servers are installed with a self-circulating domain name resolution system, one provides daily recursive resolution services, and the other is a backup. The two devices maintain data synchronization and consistency through the interface, one is the main server, and the other is the backup server. The localDNS of the three major operators establishes a connection with the main server of the self-circulating domain name resolution system. At the same time, the main server of the self-circulating domain name resolution system maintains connections with foreign root and top-level domain source servers. The self-circulating domain name resolution system server will synchronize the international root, top-level domain data, mirror copy operators and international export traffic data through the DNS protocol to complete data collection. For the overall deployment structure diagram, see figure 2 .

[0094] The server of the self-circulating domain n...

Embodiment 3

[0114] When the user initiates a domain name resolution request, if the corresponding operator localDNS has relevant records, the resolution result will be returned; if not, it will recurse to the self-loop domain name resolution system. The specific resolution process is as follows: Figure 4 As shown, for example: the user enters www.qq.com, the parsing process is as follows:

[0115] 1) The user enters the www.qq.com domain name in the browser and initiates a request to the operator's localDNS. The operator's localDNS server looks up the cache to see if there is such a domain name mapping relationship.

[0116] 2) If yes, return directly to complete domain name resolution.

[0117] 3) If there is no corresponding domain name mapping relationship, it recurses upwards to the self-loop domain name resolution system server. After receiving the request, the server queries whether there is a secondary domain (qq.com) NS address record in the data index database.

[0118] 4) If ...

Abstract

The invention provides an area data transmission method, a self-circulation domain name analysis system and a self-circulation domain name analysis method. All index data is acquired via an area transmission and package capturing technology, and jointed with an operator to provide a domain name analysis service for domestic users. Once a foreign root domain name server breaks down, the system canbe used as an emergency platform to analyze data according to root domain, top domain and authority domain name server index authorization, so that a recursion result can be acquired without enablinga user request to go aboard, and the security threats and potential economic losses caused by foreign root domain vicious DDoS attacks and hijacks are effectively evaded. The self-circulation domain name analysis system has an enormous data analysis capacity, and uses a machine learning technology to perform data analysis and security monitoring, so that the integrated service of data collection,analysis, recursive solution and security monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of computer technology, in particular to an area data transmission method, a self-circulating domain name resolution system and method. Background technique [0002] The Domain Name System (DNS) assigns domain name addresses and IP addresses to hosts on the Internet. When a user enters a domain name, the domain name system will provide the service of converting the domain name address into an IP address. The root domain name server is the foundation of the domain name system and an essential facility for building the Internet. When Chinese users access foreign websites with suffixes such as ".com", most still need to go through foreign root and top-level domain name servers for resolution. The most powerful, direct, and deadly way to attack the entire Internet is to attack the root domain name server. The following lists some domestic cases of DNS attacks: [0003] On the morning of January 12, 2010, Bai...
