Description

Corresponding relation analysis method and equipment

Technical Field

The invention relates to the field of computers, in particular to a method and equipment for analyzing a corresponding relation.

Background

As shown in fig. 1, a general flow of DNS domain name resolution in an existing Content Delivery Network (CDN) is as follows:

(1) a client initiates domain name resolution, and firstly inquires whether an ip address corresponding to a domain name is cached in a domain name server (local DNS) in a local area, wherein the domain name server (local DNS) in the local area provides caching and recursive services;

(2) if the local DNS does not hit, the local DNS will request resolution directly to a root Domain name Server (root server);

(3) the root domain name server returns to the local domain name resolution server, and the address of the domain name server of a query domain;

(4) and (4) the local domain name resolution server sends a request to the domain name server address returned in the step (3).

(5) By analogy, the local DNS performs iterative resolution until an authoritative domain name server of the domain name is resolved, and the authoritative domain name server returns the ip corresponding to the requested domain name to the local DNS, wherein the authoritative domain name server is a server for resolving the domain name through the upper-level authorization;

(6) finally, the local DNS returns the ip to the client and the ip is cached locally.

For the content delivery network, the DNS F in fig. 1 is an authoritative domain name server that requests a domain name, the ip of the request end received by the DNS F is the ip of the local domain name resolution server (local DNS), and the scheduling system of the content delivery network performs scheduling according to the ip address of the local DNS. If the client local DNS configuration is wrong, for example: the ip address of the client is ip communicated in Beijing, but the local DNS is configured to 8.8.8.8 U.S. ip address, so the scheduling system still considers that the requester is U.S. user, and will schedule and flow control according to U.S. user policy, that is, the scheduling of the content distribution network is performed with ip of local DNS, but the ip address requested by the client is ip of the client rather than ip of local DNS at the internet client of the content distribution network service, and the problem of scheduling and flow control inaccuracy exists because the corresponding relation between the client ip and the local DNS ip cannot be known.

As defined herein, computer readable media does not include non-transitory computer readable media (transient media), such as modulated data signals and carrier waves.

First, the present application will be described with reference to a specific embodiment: as shown in fig. 2, when the client 1 of the internet user accesses a main site with a relatively large access amount (such as an official website of a shopping website 3),

in step s1, the client 1 first sends the domain name of the website 3 to the local domain name resolution server 2(local DNS) for resolution, and if there is no IP address corresponding to the domain name of the website 3 on the local domain name resolution server 2(local DNS),

step s2, the local domain name resolution server 2 sends the domain name of the website 3 to the authoritative DNS 4 of the website for resolution;

step s3, the authoritative DNS 4 of the website returns the IP address corresponding to the domain name of the website 3 obtained by resolution to the local domain name resolution server 2;

step s4, the local domain name resolution server 2 returns the received IP address corresponding to the domain name of the website 3 to the client 1;

step s5, the client 1 sends an access request to the website 3 according to the received IP address corresponding to the domain name of the website 3;

step s6, the web site 3 embeds js code into html file returned to the client 1 based on the access request;

the browser of the client 1 runs the html file, firstly, the rendering action of the main station is carried out, then, the domain name (such as url: http:// a.com/1.txt) of the resource (1.txt) on the fixed resource service site is executed in the js code, wherein,

in step s7, the client 1 sends the domain name of the resource (1.txt) on the fixed resource service site 5 to the local domain name resolution server 2 for resolution, if there is no IP address corresponding to the domain name of the resource (1.txt) on the fixed resource service site 5 on the local domain name resolution server 2(local DNS),

step s8, the local domain name resolution server 2 sends the domain name of the resource (1.txt) on the fixed resource service site 5 to the authoritative DNS 6 of the fixed resource service site for resolution;

step s9, the authoritative DNS 6 of the fixed resource service site returns the IP address corresponding to the domain name of the resource (1.txt) on the fixed resource service site 5 obtained by the resolution to the local domain name resolution server 2;

step s10, the local domain name resolution server 2 returns the received IP address corresponding to the domain name of the resource (1.txt) on the fixed resource service site 5 to the client 1;

step s11, the client 1 sends an access request to the fixed resource service site 5 according to the received IP address corresponding to the domain name of the resource (1.txt) on the fixed resource service site 5;

step s12, after the fixed resource service site 5 receives the request message (such as http:// a.com/1.txt), it records the client ip, and generates a random number, and combines it with the request domain name, the combination mode is:

(1) including but not limited to replacing "-" with "in the client ip address"

(2) Custom rule domain names, including but not limited to: zone (zone) of random number-converted ip address-request Domain name-authoritative Domain Name Server (DNS)

If the ip address of the client is 11.11.11.11 and the requested domain name is a.com, then the fixed resource service site receives the request message and generates a random number of 342438901, and the random number is combined into 342438901-11-11-11-a.com.danuoyi.tbcache.com, wherein the requested domain name can be a.com, and the region of the authoritative domain name server can be danuoyi.tbcache.com;

the fixed resource serving site 5 returns the new domain name to the client 1.

Step s13, the client 1 sends the received new domain name to the local domain name resolution server 2 for resolution, because the random number generated by the fixed resource service site 5 each time is different, the domain name received by the local domain name resolution server (local DNS) of the client each time is a completely new domain name, so the local domain name resolution server 2 will not hit the corresponding IP address,

there would be step s14, querying the authoritative DNS 7 for danuoyi.tbcache.com zone;

step s15, the authoritative DNS 7 of the anuoyi.tbcache.com zone receives the request, firstly resolves the ip address of the client (restore 11.11.11.11), and then records the corresponding relation between the ip and the ip address of the local DNS to a local file;

step s16, the authoritative DNS 7 of the anuoyi.tbcache.com zone returns the IP address corresponding to the new domain name to the client.

Through the method, the corresponding relation between the local DNS and the client ip can be obtained.

After finding the corresponding relationship between the localDNS ip and the client ip, the method can be applied to the following scenes:

the Guangdong province Unicom machine room is provided with 4 cdn servers for providing acceleration service for netizens. Guangdong province has two localDNS (localDNS A and localDNS B) in communication, the scheduling of the CDN is scheduled based on the localDNS, that is, when each localDNS requests an authoritative DNS, the authoritative DNS returns a closer local DNS to the localDNS, and the authoritative DNS treats each localDNS equally, however, in practice, each localDNS corresponds to clients with different orders of magnitude in ip, for example, the localDNS A in the Guangdong province treats 1 ten thousand of clients in the jurisdiction, but the localDNS B in the jurisdiction treats 10 thousand of clients in the jurisdiction, but the authoritative DNS does not know that the localDNS A and the localDNS B are treated equally, when two localDNS requests the authoritative DNS, the authoritative DNS distributes the average clients of 4 servers in the Guangdong province to the clients in the jurisdiction, but actually the network requests represented by the two localDNS are not completely corresponding to the local DNS, so that the corresponding machine room is found by the authoritative DNS, the number of network requests can be calculated when the localDNS requests the authoritative DNS each time, and finally, the server ip can be finely distributed to different localDNS according to the result.

As shown in fig. 2, according to an aspect of the present application, there is provided a method for analyzing a correspondence relationship at a website, including:

the network station end receives an access request from a client;

and the website generates a webpage file of the access request and sends the webpage file to the client, wherein the webpage file comprises an execution file for sending a domain name combination request to a fixed resource service website. Specifically, since the prior art cannot acquire the corresponding relationship between the IP address of the client and the IP address of the local domain name resolution server, and a means for automatically triggering the process of acquiring the corresponding relationship between the IP address of the client and the IP address of the local domain name resolution server is required to acquire the corresponding relationship between the IP address of the client and the IP address of the local domain name resolution server, in this embodiment, an execution file for sending a domain name combination request to a fixed resource service site is embedded in a web file returned by a website to the client, and when a subsequent client opens a received web file, the execution file for sending a domain name combination request to a fixed resource service site can be automatically executed, so that the process of acquiring the corresponding relationship between the IP address of the client and the IP address of the local domain name resolution server is automatically started.

In the method for analyzing the correspondence of the website, the webpage file includes an HTML file. Specifically, the website generates a web page file of the access request and sends the web page file to the client, where the web page file may be an HTML (hypertext markup language) file, and the making of the hypertext markup language file is not very complicated, but has a powerful function, and supports the file embedding of different data formats.

In the method for analyzing the correspondence of the website, the execution file includes a JS execution file embedded in the web page file. Specifically, a JS (javascript) execution file may be embedded in the web page file, where JS is an transliterated script language, and is a dynamic type, a weak type, a prototype-based language, and a built-in support type. In the previous embodiment, a JS execution file may be embedded in the HTML file, and a dynamic function of automatically starting a process of acquiring a correspondence between the IP address of the client and the IP address of the local domain name resolution server is added to the HTML webpage.

In the method for analyzing the correspondence of the website end in the embodiment of the application, the website includes a website with an access amount greater than a preset threshold. Specifically, since the probability of the user accessing the websites is high, the execution file is embedded in the webpage files returned by the websites to the user, so that the collection efficiency and the comprehensiveness of the corresponding relationship between the IP address of the client and the IP address of the local domain name resolution server can be improved.

According to another aspect of the present application, there is also provided a method for analyzing a mapping relationship at a fixed resource server site, including:

the method comprises the steps that a fixed resource service site end receives a domain name combination request from a client, wherein the domain name combination request is automatically sent when the client executes a webpage file returned by a website, and the domain name combination request comprises an IP address of the client;

and the fixed resource service site terminal generates a combined domain name according to the IP address of the client and sends the combined domain name to the client, wherein the combined domain name comprises a random number, the IP address of the client and a zone (zone) of an authoritative domain name server. Specifically, as shown in fig. 2, a client sends an access request to a website, and receives a web page file corresponding to the access request from the website, where the web page file includes an execution file that sends a domain name combination request to a fixed resource service site, the client executes the web page file to automatically send the domain name combination request to the fixed resource service site while opening a corresponding web page, the domain name combination request includes an IP address of the client, then the fixed resource service site generates a combined domain name according to the IP address of the client and sends the combined domain name to the client, the combined domain name includes a random number, the IP address of the client, and a region of an authoritative domain name server, so that a correspondence between the IP address of the client and the IP address of a local domain name resolution server can be collected subsequently through the region of the authoritative domain name server, the random numbers generated each time are different, so that the domain name received by a local domain name resolution server (local DNS) of the client is a brand new domain name each time, the local DNS cannot hit, and the brand new domain name is inevitably inquired from an authoritative domain name server in the area, so that the corresponding relation between the IP address of the client in the combined domain name and the IP address of the local DNS is ensured, and the IP addresses can be finally collected by the authoritative domain name server.

In this embodiment, the fixed resource service site provides a service for processing and refining an http request message IP of the client, the domain name combination request may include a request domain name and an IP address of the client, and the fixed resource service site may combine a random number, an IP address of the client, the request domain name, and a zone (zone) of an authoritative domain name server into a new domain name according to a preset domain name customization rule, and return the new domain name to the client.

In the method for resolving a correspondence of a fixed resource service site end according to an embodiment of the present application, the domain name combination request includes an access request of the fixed resource service site and an IP address of a client. Specifically, the domain name combination request may include an access request of any fixed resource service site, such as url (e.g., http:// a.com/1.txt) of any resource 1.txt on the fixed resource service site a.com, so as to ensure that the client can receive the generated combined domain name from the fixed resource service site as long as sending any access request to the fixed resource service site.

In the method for resolving a correspondence of a fixed resource server site end according to an embodiment of the present application, generating a combined domain name according to an IP address of a client includes:

generating a random number based on the domain name combination request;

carrying out format conversion on the IP address of the client;

determining a region of an authoritative domain name server;

and combining the random number, the IP address of the client after format conversion and the region of the authoritative domain name server to generate a combined domain name. Specifically, because the format of the IP address is different from that of the domain name, the IP address is converted into a combined domain name meeting the format requirement.

In the method for analyzing correspondence of a fixed resource server site end according to an embodiment of the present application, converting the format of the IP address of the client may include replacing ".", in the IP address of the client, with "-". Here, the term "in the domain name has a specific meaning, and the term" is replaced with a term.

For example, the ip address of the client is 11.11.11.11, and the requested domain name is a.com, then after receiving the request message, the fixed resource service site generates a random number of 342438901, and combines the random number into 342438901-11-11-11-11-a.com.
