(2) intelligent DNS subsystem.Receive the analysis request of Local DNS, the IP address of record Local DNS, and specific, unique subdomain name of analysis LocalDNS request, obtain by surveying globally unique identifier's sign indicating number that heavy guide system generates, IP address and the globally unique identifier's sign indicating number of Local DNS is saved in the data record subsystem.
(3) data record subsystem.The Core Feature of data record subsystem is a database, preserves by surveying client ip address and the globally unique identifier's sign indicating number that heavy guide system sends, and the Local DNS IP address and the overall unique identification code that send by intelligent DNS subsystem.And will survey data that heavy guide system and intelligent DNS system send and follow according to globally unique identifier's sign indicating number and mate, merge, the data of merging are saved in the database use for statistical analysis.
(4) statistical analysis subsystem.Main being responsible for carried out statistics and analysis to the detection data in the data recording subsystem, and system finally adds up and uses some concrete Local DNS to carry out the IP address of the computer of analysis service.
Adopt system of the present invention can obtain visitor's home domain name resolution server, the general steps of enforcement is:
At first on the website that needs are surveyed, embed the JavaScript code, browser resolves JavaScript code, ask the heavy guide module of detection of detection system then, survey the IP address that heavy guide module at first writes down the browser end computer, return directive script then, make browser ask the intelligent DNS module of detection system once more, the IP of LocalDNS under the intelligent DNS module records, data recordin module merges the data of twice request, deposits to data warehouse.Through the certain hour section, after detection finishes, add up the IP address information of each LocalDNS back correspondence at last by analysis module.
Describe in detail below in conjunction with Fig. 1:
(1) provides specific HTML code by detection system, it is embedded on the Website page that is detected.The address of supposing the website is
Http:// www.website.com, the address of service of surveying heavy guide module in the detection system is
Http:// www.trace.com/redirect.cgi, then exist
Http:// www.website.com/index.htmlEmbed following HTML code:
<iframe?height＝”0”width＝”0”src＝”http://www.trace.com/redirect.cgi”></iframe>
Guest access when the website
Http:// www.website.com/index.htmlDuring the page, browser can be resolved above-mentioned HTML code, thereby from trend
Http:// www.trace.com/redirect.cgiSend request.
(2) survey heavy guide module and receive the request of sending from guest browser after, at first, obtain the IP address of client computer, generate one by program then and close an innings unique identification code, the IP address of supposing client in this request is 4.4.4.4, the unique identification sign indicating number that generates is: 000001, IP and globally unique identifier's sign indicating number are saved in the data record subsystem.
(3) suppose that intelligent DNS subsystem has the mandate of * .dns.trace.com subdomain name.The subdomain name that the overall situation is unique: 000001.dns.trace.com of then heavy guide system's generation, and return following page code:
<script>window.location.href＝’http://000001.dns.trace.com’</script>
(4) after client's browser is received the page code that heavily the guide system returns, attempt loading
Http: // 000001.dns.trace.com,,, thereby ask the parsing of this domain name to its Local DNS so the A record of this domain name is browsed and do not known to client because this domain name is a brand-new overall unique domain name that is generated by detection system.
(5) in like manner, Local DNS does not have the data cached of this domain name yet, so to the parsing of intelligent DNS subsystem request 000001.dns.trace.com domain name.
(6) because intelligent DNS system has the mandate of * .dns.trace.com subdomain name, therefore after receiving the analysis request of Local DNS for subdomain 000001.dns.trace.com, at first obtain the IP address of Local DNS, the IP address of supposing Local DNS is 4.4.4.5, first of Qing Qiu subdomain section is converted to globally unique identifier's sign indicating number then: 000001, and at last with the IP of LocalDNS with close innings unique identification sign indicating number and be saved in the data record subsystem.The data record subsystem is followed according to globally unique identifier's sign indicating number and automatically itself and the visitor IP record that writes down is before merged, and obtains following record:
| The unique identification sign indicating number | Visitor IP | Local?DNS?IP |
| 000001 | 4.4.4.4 | 4.4.4.5 |
(7) after detection after a while, the data record subsystem can be collected a large amount of detection datas, transfer to the statistical analysis subsystem then the record of identical Local DNS IP is carried out polymerization, utilize this Local DNS to carry out all IP set of analysis request thereby obtain, after obtaining the IP collective data, carry out the analytical work of following steps:
A. the repetition IP data in will tabulating merge, and number of repetition are counted the weight of this IP.Suppose that the IP data in the initial list are as follows:
| Visitor IP |
| 3.3.3.3 |
| 3.3.3.3 |
| 7.7.7.7 |
| 9.9.9.9 |
| 7.7.7.7 |
| 7.7.7.7 |
Then the data that merge after handling are:
| Visitor IP | Weight |
| 3.3.3.3 | 2 |
| 7.7.7.7 | 3 |
| 9.9.9.9 | 1 |
B. inquire about IP geographic position data storehouse, inquire about the zone and the ISP at each IP place, obtain similar following form:
| Visitor IP | Weight | The region | ISP |
| 3.3.3.3 | 2 | Jiangsu | China Telecom |
| 7.7.7.7 | 3 | Jiangsu | China Telecom |
| 9.9.9.9 | 1 | Anhui | CHINAUNICOM |
C. the weight that merges same area IP obtains similar following form:
| Weight | The | ISP | |
| 5 | Jiangsu | China Telecom | |
| 1 | Anhui | CHINAUNICOM |
D. obtain the region and the ISP of weight maximum, this zone is the primary service area of this Local DNS of 4.4.4.5, and the result is as follows:
| The region | ISP |
| Jiangsu | China Telecom |
E. upgrade the CDN parses policy, all IP addresses are the Local dns resolution request of 4.4.4.5 later on, and the node IP address of serving the user of Jiangsu China Telecom in the CDN system is returned as the A record.Thereby provide the CDN that more optimizes service.
