Background technology
The domain name mapping of prior art all uses domain name system (DNS, Domain Name System)
Standard agreement, its basic procedure is as follows: when client wants accesses certain page, first from unified resource
Finger URL (URL, Uniform Resource Locator) extracts domain name, then sends this domain name extremely
Local domain name server (Local DNS) carries out domain name mapping.If Local DNS is slow in this locality
Inquire this domain name corresponding domain name mapping result in depositing, then direct to the corresponding domain name solution of client return
Analysis result；Otherwise, Local DNS is asked step by step by interative computation, gets this domain name corresponding
Domain name mapping result simultaneously returns to client.Client is according to the IP address in domain name mapping result even
Connect service server, send HTTP (HTTP, Hyper Text Transfer Protocol)
Ask thus obtain content of pages.
But prior art there are the following problems: every time access URL link, be required for passing through Local
DNS carries out network interaction to carry out domain name mapping.Request Local DNS is the mistake that a synchronization waits
Journey, can cause time delay, increases the overall time overhead accessing URL, brings poor user
Experience.And Local DNS can introduce parsing and postpone, and, this time delay is simultaneously unstable,
There is the domain name resolution process under bigger fluctuation, extreme case very very long.For example, when domain name is not ordered
During middle Local DNS cache, Local DNS needs the multiple authority's domain servers with upstream to carry out net
Cross winding is mutual, and iteration is repeatedly to complete domain name mapping.It is that synchronization waits between repeatedly mutual, time delay
Being their superposition, at this moment whole domain name resolution process is just very very long.When Local DNS receives neofield
During name request, or when the life span (TTL, Time To Live) of domain name caching is expired,
The situation of caching will occur to hit, and at this moment resolving postpones and fluctuate all can become big.

Name cache table；5th unit 15, for inquiring about domain name cache table to obtain according to user access request
Take corresponding domain name analysis result.
Here, in prior art during user to access pages, need to Local dns server initiated domain
Name analysis is asked, and is then returned corresponding domain name mapping result by Local DNS, and its network interaction is made
Become time delay.The terminal device of the application before user to access pages, for example terminal or its take
The application initial phase carrying, with regard to the request of initiated domain name analysis, frequent for focus website or user
The website browsing carries out domain name pre-parsed.The domain name of the website that focus website or user often browse can
To be pre-stored within pre-parsed domain name table, the website that user often browses can be browsed by user and go through
Records of the Historian record obtains, and focus website can be set by cloud server or terminal.With focus net
As a example by standing, first terminal is stored in some focus websites domain name in pre-parsed domain name table, should in terminal
With initial phase, first module 11 asks first server to multiple heat according to pre-parsed domain name table
Point domain name carries out domain name mapping；Multiple focus territories that described first server is returned by the 3rd unit 13
The domain name mapping result of name stores to domain name cache table；When user asks accession page, Unit the 5th
15 inquire about domain name cache table to obtain corresponding domain name analysis result, territory according to this user access request
Name cache table is located at terminal side, thus avoid the network interaction with Local dns server.Territory
Name cache table can comprise domain name and corresponding IP address thereof, it is also possible to comprise life span (TTL),
Protocol type, port information etc., in order to ensure domain name mapping result integrality or prevent mid-level net
Under the premise of the distorting of network, domain name cache table can also comprise safety check value.Terminal is from local domain name
Cache table reads corresponding domain name mapping result and connects corresponding business service according to IP address therein

Here, in prior art during user to access pages, need to Local dns server initiated domain
Name analysis is asked, and is then returned corresponding domain name mapping result by Local DNS, and its network interaction is made
Become time delay.The terminal device of the application before user to access pages, for example terminal or its take
The application initial phase carrying, with regard to the request of initiated domain name analysis, frequent for focus website or user
The website browsing carries out domain name pre-parsed.The domain name of the website that focus website or user often browse can
To be pre-stored within pre-parsed domain name table, the website that user often browses can be browsed by user and go through
Records of the Historian record obtains, and focus website can be set by cloud server or terminal.With focus net
As a example by standing, first terminal is stored in some focus websites domain name in pre-parsed domain name table, should in terminal
With initial phase, terminal request second unit 22 carries out domain name mapping to multiple focus domain names；The
Four unit 24 are to described terminal returns to field name analysis result.Terminal is by multiple focus domain names of return
Domain name mapping result stores to domain name cache table；When user asks accession page, terminal is according to this use
Family access request inquiry domain name cache table is to obtain corresponding domain name analysis result, and domain name cache table sets
In terminal side, thus avoid the network interaction with Local dns server.Domain name cache table can
To comprise domain name and corresponding IP address thereof, it is also possible to comprise life span (TTL), protocol type,
Port informations etc., before in order to ensure domain name mapping result integrality or prevent the distorting of go-between
Putting, domain name cache table can also comprise safety check value.Terminal reads from local domain name cache table
Corresponding domain name mapping result simultaneously connects corresponding service server to obtain phase according to IP address therein
Answer the page.First server is not existing Local dns server, but in order to realize the application
Purpose and the HTTP dns server that carries out corresponding configuration with terminal.HTTP dns server is permissible
Receive the URL that terminal sends, then carry out the protocol conversion of HTTP to DNS, in terminal side
Initial phase by HTTP dns server replace terminal carry out domain name mapping, translate domain names into knot
Fruit returns and stores to the domain name cache table of terminal, is adjusted from this locality according to requirements for access by terminal
With, save carry out domain name mapping by Local dns server and cause the network interaction time wave
Take, improve page access speed.
Specifically, described second unit 22 includes: the 2nd 1 subelement the 2201 and the 2nd 2 subelement
2202。

Domain name analysis request comprises the N number of domain name in pre-parsed domain name table, and N is positive integer.Two or two
Subelement 2202, for obtaining the domain name mapping result of described N number of domain name.
Here, the 2nd 1 subelement 2201 receives multiple domain names that terminal once sends, many to obtain
The domain name mapping result of individual domain name, reduces and the interaction times of first server, time-consuming and drop
The access burden of low server.Resolve multiple domain name and resolve individual domain name to HTTP dns server
For be similar, a simply loop iteration, obtain the analysis result of each domain name respectively,
After the analysis result of all domain names is merged by preset format, together return to terminal.Returning
Data message in, by domain name, analysis result and corresponding relation thereof according to preset format tissue, one by one
Correspondence, just can distinguish each domain name mapping result by resolving data message.Preferably, terminal with
The mutual of first server is carried out by JSON (JavaScript Object Notation) form.
Specifically, described two or two subelement 2202 is used for: by nslookup information database or
Person obtains the domain name mapping result of described N number of domain name by domain name mapping.
Here, after receiving domain name mapping request, first the two or two subelement 2202 can inquire about this
The domain-name information database that ground is arranged, to obtain the domain name mapping result corresponding with domain name.If this
When the domain-name information database that ground is arranged does not stores the domain name mapping result of corresponding domain name, the two or two son
Unit 2202 asks existing second server (Local dns server) to obtain corresponding domain name
Domain name mapping result.For example, for each domain name in terminal request, first server can be according to
The DNS Protocol of standard, generates a DNS request, and this DNS request comprises domain name and terminal IP
Information, be sent to second server, returned the analysis result of this domain name by second server.
Alternatively, described first server 2 also includes: the 6th unit 26.
6th unit 26, for finding that when described terminal the life span of domain name analysis result is expired
When, this domain name mapping result is updated by the request according to described terminal.
Here, life span (TTL, Time To Live) is one of standard DNS Protocol art
Language, the effective time of representative domain name analysis result.For example, when user carries out page access, terminal pair
The TTL of the domain name mapping result in domain name cache table judges, when this domain name mapping result of discovery
When TTL is expired, terminal directly returns corresponding domain name analysis result, carries out page visit for user
Ask.Meanwhile, this domain name mapping result is updated by first server described in terminal request.Right
But in the still effective situation of the expired domain name mapping result of TTL, page visit can be carried out as early as possible
Ask.When TTL is expired and domain name mapping result lost efficacy, the page access of terminal loses
Lose, but the 6th unit 26 have updated the domain name mapping result of this domain name and returned to terminal,
Domain name mapping result after terminal will update stores to domain name cache table, and again carries out according to user
The request of page access, returns the domain name mapping result after updating, successfully to carry out page access.The
Six unit 26 can be carried out the renewal of domain name mapping result by the two or two subelement 2202.
Fig. 3 illustrates the structural representation of the quick domain name analysis system according to one aspect of the application.As

Described first server is asked to carry out domain name mapping.
Here, the application provides a kind of fault tolerant mechanism, when the territory not having user to ask in domain name cache table
Name domain name mapping result when, carry out domain name mapping to existing Local dns server, will not be right
The business of client impacts.Meanwhile, first server initiated domain name analysis is asked, will
The domain name mapping result cache that first server returns, in domain name cache table, so, accesses next time
During this domain name, just can inquire corresponding domain name mapping result in domain name cache table.
Fig. 4 illustrates and shows according to the flow process at the quick domain name analytic method of terminal of one aspect of the application
It is intended to.As shown in Figure 4, the quick domain name analytic method in terminal includes:
Step S401, asks first server to carry out domain name mapping according to pre-parsed domain name table；
Step S402, stores the domain name mapping result that described first server returns to domain name caching
Table；
Step S403, inquires about domain name cache table to obtain corresponding domain name solution according to user access request
Analysis result.
Here, in prior art during user to access pages, need to Local dns server initiated domain
Name analysis is asked, and is then returned corresponding domain name mapping result by Local DNS, and its network interaction is made
Become time delay.The terminal device of the application before user to access pages, for example terminal or its take
The application initial phase carrying, with regard to the request of initiated domain name analysis, frequent for focus website or user
The website browsing carries out domain name pre-parsed.The domain name of the website that focus website or user often browse can
To be pre-stored within pre-parsed domain name table, the website that user often browses can be browsed by user and go through
Records of the Historian record obtains, and focus website can be set by cloud server or terminal.With focus net
As a example by standing, first terminal is stored in some focus websites domain name in pre-parsed domain name table, should in terminal
With initial phase, terminal asks first server to enter multiple focus domain names according to pre-parsed domain name table
Row domain name mapping；The domain name mapping result of multiple focus domain names that described first server is returned by terminal
Store to domain name cache table；When user asks accession page, terminal is looked into according to this user access request
Inquiry domain name cache table is to obtain corresponding domain name analysis result, and domain name cache table is located at terminal side,
Thus avoid the network interaction with Local dns server.Domain name cache table can comprise domain name and
Its corresponding IP address, it is also possible to comprise life span (TTL), protocol type, port information etc.,
Under the premise of in order to ensure domain name mapping result integrality or prevent the distorting of go-between, domain name is delayed
Deposit table and can also comprise safety check value.Terminal reads corresponding domain name solution from local domain name cache table
Analysis result simultaneously connects corresponding service server to obtain respective page according to IP address therein.First
Server is not existing Local dns server, but in order to realize the application purpose and and terminal
Carry out the HTTP dns server of corresponding configuration.HTTP dns server can receive terminal and send
URL, then carry out the protocol conversion of HTTP to DNS, at the initial phase of terminal side
Replaced terminal to carry out domain name mapping by HTTP dns server, translate domain names into result and return and store
To the domain name cache table of terminal, called from this locality according to requirements for access by terminal, save and pass through
The network interaction time waste that Local dns server carries out domain name mapping and causes, improves the page
Access speed.
Specifically, step S401 asks first server to carry out domain name mapping according to pre-parsed domain name table
Including:
Step S4011, the request of sending domain name analysis is to described first server；Wherein, domain name
Analysis request comprises the N number of domain name in described pre-parsed domain name table, and N is positive integer；
Step S4012, receives the domain name mapping knot of described N number of domain name that described first server returns
Really.
Here, terminal once sends multiple domain name to first server, to obtain the domain name of multiple domain name
Analysis result, reduces and the interaction times of first server, the time-consuming and visit that reduces server
Ask burden.Resolving multiple domain name and resolving individual domain name is similar for HTTP dns server
, a simply loop iteration, obtain the analysis result of each domain name respectively, finally by all territories
The analysis result of name is merged by preset format, together returns to terminal.At the data message returning
In, by domain name, analysis result and corresponding relation thereof according to preset format tissue, one_to_one corresponding, pass through
Resolve data message and just can distinguish each domain name mapping result.Preferably, terminal and first server
Mutual carried out by JSON (JavaScript Object Notation) form.
Alternatively, described method also includes:
Step S404, when the life span of domain name analysis result is expired, accessing according to user please
Ask and directly return described corresponding domain name analysis result；
Step S405, asks described first server to be updated this domain name mapping result.
Here, life span (TTL, Time To Live) is one of standard DNS Protocol art
Language, the effective time of representative domain name analysis result.For example, when user carries out page access, terminal pair
The TTL of the domain name mapping result in domain name cache table judges, when this domain name mapping result of discovery
When TTL is expired, terminal directly returns corresponding domain name analysis result, enters for according to access request
Row connects.Meanwhile, this domain name mapping result is updated by first server described in terminal request.
But the still effective situation of expired domain name mapping result, can carry out the page as early as possible for TTL
Access.When TTL is expired and domain name mapping result lost efficacy, the page access of terminal
Failure, but first server have updated the domain name mapping result of this domain name and returned to terminal
Returning, the domain name mapping result after terminal will update stores to domain name cache table, and according to user again
The accessing page request carrying out, returns the domain name mapping result after updating, successfully to carry out page access.
Alternatively, described method also includes:
Step S406, when not inquiring corresponding domain name analysis result in domain name cache table,
Request second server carries out domain name mapping and asks described first server to carry out domain name mapping.
Here, second server refers to existing Local dns server.The application provides a kind of fault-tolerant
Mechanism, when the domain name mapping result of the domain name not having user to ask in domain name cache table, terminal is to now
Some Local dns servers carry out domain name mapping, will not impact the business of client.With
This simultaneously, first server initiated domain name analysis is asked by terminal, the domain name returning first server
Analysis result is buffered in domain name cache table, so, when accessing this domain name next time, and just can be in domain name
Cache table inquires corresponding domain name mapping result.
Fig. 5 illustrates the flow process of the quick domain name analytic method in service end according to one aspect of the application
Schematic diagram.As it is shown in figure 5, the described quick domain name analytic method in service end includes:
Step S501, the request according to terminal carries out domain name mapping；
Step S502, to described terminal returns to field name analysis result, for described terminal by domain name
Analysis result stores inquires about domain name cache table to domain name cache table and according to the access request of user
To obtain corresponding domain name analysis result.
Here, in prior art during user to access pages, need to Local dns server initiated domain
Name analysis is asked, and is then returned corresponding domain name mapping result by Local DNS, and its network interaction is made
Become time delay.The terminal device of the application before user to access pages, for example terminal or its take
The application initial phase carrying, with regard to the request of initiated domain name analysis, frequent for focus website or user
The website browsing carries out domain name pre-parsed.The domain name of the website that focus website or user often browse can
To be pre-stored within pre-parsed domain name table, the website that user often browses can be browsed by user and go through
Records of the Historian record obtains, and focus website can be set by cloud server or terminal.With focus net
As a example by standing, first terminal is stored in some focus websites domain name in pre-parsed domain name table, should in terminal
With initial phase, terminal request first server carries out domain name mapping to multiple focus domain names；First
Server is to described terminal returns to field name analysis result.The domain name of multiple focus domain names by return for the terminal
Analysis result stores to domain name cache table；When user asks accession page, terminal is visited according to this user
Ask requesting query domain name cache table to obtain corresponding domain name analysis result, domain name cache table is located at end
End side, thus avoid the network interaction with Local dns server.Domain name cache table can be wrapped
Containing domain name and corresponding IP address thereof, it is also possible to comprise life span (TTL), protocol type, end
Message breath etc., in order to ensure domain name mapping result integrality or prevent go-between distort premise
Under, domain name cache table can also comprise safety check value.Terminal reads phase from local domain name cache table
The domain name mapping result answered to connect corresponding service server according to IP address therein corresponding to obtain
The page.First server is not existing Local dns server, but in order to realize the application mesh
And carry out the HTTP dns server of corresponding configuration with terminal.HTTP dns server can connect
Receive the URL that terminal sends, then carry out the protocol conversion of HTTP to DNS, in terminal side
Initial phase is replaced terminal to carry out domain name mapping by HTTP dns server, translates domain names into result
Return and store to the domain name cache table of terminal, called from this locality according to requirements for access by terminal,
Save the network interaction time waste carrying out domain name mapping by Local dns server and causing,
Improve page access speed.
Specifically, step S501 carries out domain name mapping according to the request of terminal and includes:
Step S5011, receives the domain name mapping request that described terminal sends；Wherein, domain name solution
Analysis request comprises the N number of domain name in pre-parsed domain name table, and N is positive integer；
Step S5012, obtains the domain name mapping result of described N number of domain name.
Here, first server receives multiple domain names that terminal once sends, to obtain multiple domain name
Domain name mapping result, reduces and the interaction times of first server, time-consuming and reduce server
Access burden.Resolve multiple domain name and parsing individual domain name is class for HTTP dns server
As, a simply loop iteration, obtain the analysis result of each domain name respectively, finally will be all
The analysis result of domain name is merged by preset format, together returns to terminal.In the datagram returning
Wen Zhong, by domain name, analysis result and corresponding relation thereof according to preset format tissue, one_to_one corresponding, leads to
Cross parsing data message and just can distinguish each domain name mapping result.Preferably, terminal and first service
The mutual of device is carried out by JSON (JavaScript Object Notation) form.
Alternatively, the domain name mapping result of the described N number of domain name of step S5012 acquisition includes:
By nslookup information database or the territory being obtained described N number of domain name by domain name mapping
Name analysis result.
Here, after first server receives domain name mapping request, can first inquire about locally located
Domain-name information database, to obtain the domain name mapping result corresponding with domain name.If it is locally located
When domain-name information database does not store the domain name mapping result of corresponding domain name, first server request the
Two servers (existing Local dns server) are to obtain the domain name mapping result of corresponding domain name.
For example, for each domain name in terminal request, first server can be assisted according to the DNS of standard
View, generates a DNS request, and this DNS request comprises the information of domain name and terminal IP, sends
To second server, returned the analysis result of this domain name by second server.
Alternatively, described method also includes:
Step S503, when the life span of described terminal discovery domain name analysis result is expired, root
According to the request of described terminal, this domain name mapping result is updated.
Here, life span (TTL, Time To Live) is one of standard DNS Protocol art
Language, the effective time of representative domain name analysis result.For example, when user carries out page access, terminal pair
The TTL of the domain name mapping result in domain name cache table judges, when this domain name mapping result of discovery
When TTL is expired, terminal directly returns corresponding domain name analysis result, carries out page visit for user
Ask.Meanwhile, this domain name mapping result is updated by first server described in terminal request.Right
But in the still effective situation of the expired domain name mapping result of TTL, page visit can be carried out as early as possible
Ask.When TTL is expired and domain name mapping result lost efficacy, the page access of terminal loses
Lose, but first server have updated the domain name mapping result of this domain name and returned to terminal,
Domain name mapping result after terminal will update stores to domain name cache table, and again carries out according to user
The request of page access, returns the domain name mapping result after updating, successfully to carry out page access.
Fig. 6 illustrates the schematic flow sheet of the quick domain name analytic method according to one aspect of the application.As
Shown in Fig. 6, this quick domain name analytic method includes:
Step S6001, the request of terminal 1 sending domain name analysis is to described first server 2；Wherein,
Domain name analysis request comprises the N number of domain name in described pre-parsed domain name table, and N is positive integer.
Here, first server refers to HTTP dns server.
Step S6002, first server 2 receives the domain name mapping request that described terminal 1 sends.
Here, first server receives multiple domain names that terminal once sends, to obtain multiple domain name
Domain name mapping result, reduces and the interaction times of first server, time-consuming and reduce server
Access burden.Resolve multiple domain name and parsing individual domain name is class for HTTP dns server
As, a simply loop iteration, obtain the analysis result of each domain name respectively, finally will be all
The analysis result of domain name is merged by preset format, together returns to terminal.In the datagram returning
Wen Zhong, by domain name, analysis result and corresponding relation thereof according to preset format tissue, one_to_one corresponding, leads to
Cross parsing data message and just can distinguish each domain name mapping result.Preferably, terminal and first service
The mutual of device is carried out by JSON (JavaScript Object Notation) form.
Step S6003, the domain name by the N number of domain name of nslookup information database for the first server 2
Analysis result；
Or, step S6004, first server 2 obtains described N number of domain name by domain name mapping
Domain name mapping result；
Here, after first server 2 receives domain name mapping request, can first inquire about locally located
Domain-name information database, to obtain the domain name mapping result corresponding with domain name.If it is locally located
Domain-name information database when not storing the domain name mapping result of corresponding domain name, first server 2 please
Ask second server 3 (Local dns server) to obtain the domain name mapping result of corresponding domain name.
For example, for each domain name in terminal request, first server can be assisted according to the DNS of standard
View, generates a DNS request, and this DNS request comprises the information of domain name and terminal IP, sends
To second server, returned the analysis result of this domain name by second server.
Step S6005, first server 2 returns the domain name mapping knot of N number of domain name to described terminal 1
