Ip address send domain name analysis request to a dns110, domain name analysis request includes target domain name.First
Dns110, according to domain name analysis request nslookup solution new record, obtains first in described target area (Beijing Area)
The ip address of web server 150.First dns110 sends the ip address of described first web server 150 to ldns130.
Ldns130 feeds back the ip address of the first web server to the client 140 in target area (for example, Beijing).Client 140 to
First web server 150 initiates web request, and obtains data.
Refer to Fig. 2, embodiments provide an a kind of embodiment of the processing method of cdn business and include:
Step 201, ldns send domain name analysis request to authoritative dns, and this domain name mapping request includes aiming field name.
The client of target area (for example, Beijing) is asked to the domain name mapping that ldns sends, domain name analysis request
Including target domain name, such as this target domain name can be www.a.com.Ldns inquires about local cache list, if not having
The cache information of www.a.com, then to authoritative dns transmission domain name analysis request, this domain name mapping request includes target to this ldns
Domain name.
Step 202, this authoritative dns inquire about ns record according to domain name analysis request, obtain the ip ground of a described dns
Location.
Ns (name server) record refers to name server record, is used to specify this domain name is come by which dns server
Parsed.Described ns record includes the Hostname of a described dns, the ip ground of described Hostname and a described dns
Location has mapping relations.
For example, ns is recorded as " a.com.cn.dns1.cdna.com ".
Hostname is " dns1.cdn.com ".
The ip of the first dns is " 1.1.1.1 ".
When this domain name is registered in registration office, authoritative dns licenses to a dns by ns record and parses this domain
Name, a dns is the dns of a cdn service provider.Therefore, this authoritative dns receives this domain name mapping request, and according to aiming field
Name inquiry ns record, obtains the ip address of a described dns.Wherein, authoritative dns obtain a dns concrete grammar permissible
For: this authoritative dns inquires about ns record according to domain name analysis request, obtains the master of a described dns according to described ns record
Machine title, described Hostname has mapping relations with the ip address of a described dns, and authoritative dns is according to described Hostname
Obtain the ip address of a described dns with described mapping relations.
Step 203, authoritative dns record the ip address sending a dns to described ldns according to described ns.
Authoritative dns passes through to inquire about the ip address that ns record obtains having a dns of parsing authority to target domain name, authority
Dns feeds back the ip address of a dns to ldns.
Step 204, ldns send domain name analysis request, domain name solution according to the ip address of a dns to a dns
Analysis request includes aiming field name.
First dns, according to domain name analysis request nslookup solution new record, obtains described target area (Beijing area
Domain) in corresponding first web server of this target domain name ip address.The ip address of target domain name and web server has to be reflected
Penetrate relation.
Step 205, a dns send the ip address of described first web server to ldns.So that client can be led to
The ip address crossing this web server directly accesses this web server, obtains data.
For example, the solution new record of a dns includes, and refers to shown in table 1 below:
Table 1
| Target domain name | Target area | The ip address of web server |
| www.a.com | beijing | 101.101.101.101 |
| www.a.com | shanghai | 202.202.202.202 |
| www.a.com | guangdong | 303.303.303.303 |
In the embodiment of the present invention, by when registration office is registered, authoritative dns is recorded the parsing power of target domain name by ns
Limit licenses to a dns of cdn service provider it is achieved that not needing to arrange cname and being introduced directly into cdn business.First cdn service
The dns of business parses to described target domain name according to domain name analysis request, obtains the web server of described target area
Ip address, effectively reduce in traditional method, recursion resolution time at least twice, while introducing cdn business, effectively
Raising domain name resolution efficiency, reduce netizen waiting time.
In the embodiment of the present invention, due to there is no cross-domain cname it is not necessary to business domain name cname is accelerated domain name to cdn,
The information of service provider will not be revealed.For example, if the entitled www.a.com of aiming field, in traditional method, cname is
" www.a.nn.com ", in www.a.nn.com, " nn " is the title of cdn service provider, readily appreciates that from this cname,
Which client cdn service provider has serviced, and easily reveals commercial matters information.In the embodiment of the present invention, not by the mode of cname
To introduce cdn business, but recorded by ns by authoritative dns and directly license to the dns of cdn service provider and realize introducing cdn
Business, therefore can be effectively protected the information of cdn service provider.
Optionally, if a dns breaks down, the processing method of cdn business provided in an embodiment of the present invention can also be entered
Row switches in real time.On the basis of the corresponding embodiment of Fig. 2, when a dns breaks down, methods described also includes:
When a described dns breaks down, the authoritative dns change ns record of described registration office, the ns record after change
There is to described target domain name for instruction the 2nd dns of parsing authority, described 2nd dns belongs to the 2nd cdn service provider.
The authoritative dns of described registration office records the ip address sending described 2nd dns to described ldns according to ns.
It is understood that when authoritative dns determines that a dns breaks down, authoritative dns changes ns record in real time, by
2nd dns execution domain name mapping function, the solution new record of the 2nd dns includes target domain name and the ip address of web server
Mapping relations.A dns is replaced to execute the step performed by the dns in the corresponding embodiment of Fig. 2 by the 2nd dns.
Specifically, refer to shown in Fig. 3, in the embodiment of the present invention, additionally provide a kind of the another of processing method of cdn business
