Also there are other identical elements in the process of the element, method, article or equipment.
As shown in Figure 1, an embodiment of the present invention provides a kind of method that user terminal gateway equipment realizes DNS scheduling, side
Method includes：
Step S101 translates domain names into result and is compared with IP address section set in preconfigured net；
Step S102, the IP address for translating domain names into IP address section set in result decline networking are encapsulated in reply message
The IP address for not falling within IP address section set in net is encapsulated in the address list of reply message most by the front end of address list
Afterwards.
Wherein, the reply message is the domain name mapping result for returning to user's access terminals.
Wherein, IP address section set refers to the segment that the IP address of operator is covered in net.Different operators are covered
The IP address section of lid is different, and the IP address section of different regions is also different, and therefore, IP address has the function of provincialism mark.
Wherein, if the corresponding IP address of IP address section set for not having and specifying in domain name mapping result, is directly pressed
Reply message is sequentially generated in domain name mapping result.
During online, sent out by user's access terminals (such as browser) to user terminal gateway equipment (such as home router)
The DNS query of domain name is sent to ask；User terminal gateway equipment initiates inquiry request to LOCAL DNS immediately, and is getting
After the analysis result of LOCAL DNS, translate domain names into result and return to user terminal gateway equipment, wherein, a domain name mapping
As a result comprising a plurality of parsing A records (Address Record) in, the processing of step S101, S102 is carried out to domain name mapping result
After obtain reply message return to user's access terminals；User's access terminals select in the address list for replying message is received
The IP address of first is come to connect into corresponding service protocol, it is final to realize online；If connection comes the IP address of first
When break down, user's access terminals can then select subsequent IP address to carry out service protocol connection successively in address list.
By the above method, the function that priority ordering is carried out to IP address is realized in user terminal gateway equipment, most
Play to big degree the DNS intelligent scheduling functions of user terminal gateway equipment.On the one hand, not all operator (ISP,
Internet Service Provider) resource sequence preferred function in net can all be configured in LOCAL DNS, therefore, pass through
The method of this implementation can make up the deficiency of LOCAL DNS scheduling features；On the other hand, it sorts for resource in configuration net preferred
The LOCAL DNS of function are solved because DNS cache poll causes LOCAL DNS scheduling strategies to lose in existing gateway equipment
The problem of effect.
Further, IP address section set in multiple nets can be pre-configured in user terminal gateway equipment, and to each
IP address section set assigned priority in net.Fall into the address of the IP address arrangement of IP address section set in the net of highest priority
The front end of list, and so on.For being moved by Jiangsu, to reduce the flow across backbone equipment, by Jiangsu Ben Sheng IP address
Section is direct-connected by this operator equity by this operator IP address section as the second priority set as the first priority set
ICP/ISP address fields as third priority set.Front and rear row can be carried out by the priority of segmentation for IP address in net
Sequence still retains for netting outer IP address, only sorts last, i.e., remains source station institute while IP address sequence is adjusted
There is domain name mapping result.It, can be by application layer softwares such as terminal browsers when the first preferred address section server failure in net
The automatic Backwards selection alternate server address that puts in order is noted down according to dns resolution A to realize (such as the second preferred address section in net)
It is fault-tolerant.
The user of different regions accesses different operators, in order to enable user terminal gateway equipment adapts to different regions
Operator needs to obtain the operator of access automatically during user terminal gateway equipment accesses network.In the above method
On the basis of embodiment, before implementation steps S101, S102, the ISP network of automatic identification access is realized by following steps
And the priority of IP address section set in net is configured, to realize priority ordering：
Step S110, the ISP network that identification user terminal gateway equipment is accessed；
Step S111, IP address section set is configured to the first priority set in the net for the ISP network that will identify that.
User terminal gateway equipment constantly detect access ISP network can increase far-end server response load, therefore,
Only just understand automatic identification ISP network when user terminal gateway equipment accesses network and carries out initial configuration and IP in net is configured
Hereafter the priority of address field set no longer carries out ISP network identification.
After general user's terminating gateway equipment installs, user will not random more switching network, but unavoidably exist
The above situation.Further, user terminal gateway equipment inner setting has clock, periodically re-recognizes what equipment was accessed
ISP network.Further, intelligent detection button is additionally provided in user terminal gateway equipment, once more switching network, user is only
The button need to be pressed, equipment can perform step S110 and step S111, re-recognize the new ISP network of access automatically, and
The priority of IP address section set in configuration net.
Preferably, step S110 includes：The ISP nets accessed by special network management path identification user terminal gateway equipment
Network.
Preferably, step S110 includes：Obtain the ISP nets that user selects in the administration interface of user terminal gateway equipment
Network, the ISP network that as user terminal gateway equipment is accessed.
Preferably, step S110 includes：The LDNS addresses of higher level LDNS are obtained, by LDNS addresses and are previously written in firmware
The IP address set of ISP be compared, so as to identify ISP network that user terminal gateway equipment is accessed.Wherein, higher level
LDNS is the LOCAL DNS being connect with user terminal gateway equipment.For example, for pppoe dial modes, user terminal gateway
The LDNS addresses (rather than user set by hand static dns address) that equipment is got according to pppoe dialing compare the IP of ISP
Address set, so as to determine the ISP network currently accessed.
Three kinds of ISP network recognition methods of above-mentioned offer can be applied in combination, and above-mentioned three kinds of ISP network recognition methods are set
Determine priority level, ISP network is identified since the high method of priority level, is connect until user terminal gateway equipment can be recognized
The ISP network entered.For example, set method of the method for highest priority to be identified by special network management path, priority second
Method be by administration interface know method for distinguishing, the method for priority third is the method for being previously written firmware firmware library, if
User terminal gateway equipment by operator webmaster remote management (such as passing through tr069 agreements), first choice pass through special network management path
Carry out ISP network identification；If it does not identify or not by the webmaster management of operator, obtains user in user terminal gateway equipment
Administration interface in the ISP network that selects；If user does not manually select ISP network, by being previously written the ISP's in firmware
IP address set identifies ISP network.
If the ISP network accessed by above-mentioned a variety of ISP network recognition methods all None- identifieds selects " to inherit parent
LDNS sorts " mechanism, i.e., when message is replied in generation, ignore priority set, directly press the higher level of user terminal gateway equipment
The IP address priority orders generation that LDNS is returned replys message and returns to user terminal.
Preferably, in the net of the ISP network in step S111 IP address section set can by following three kinds of methods from
It is dynamic to obtain：
(1) IP address section set in the net of ISP network is obtained automatically from the firmware of user terminal gateway equipment, wherein,
Firmware has been previously written IP address section set in the net of all operators；
(2) IP address section set in the net of ISP network is obtained by special network management path；
(3) IP address in the net of ISP network is downloaded by the web server that the operator of user terminal gateway equipment sets up
Duan Jihe.
Operator can be updated IP address section set in net, and therefore, user terminal gateway equipment also needs to periodically right
IP address section set is automatically updated in the net being stored thereon, to ensure the accuracy of ISP network identification.Newer method
Including：It (1), can simultaneously more in version updating for the user terminal gateway equipment with operator's related data in firmware
IP address section set in the net for the ISP that kainogenesis changes；(2) also can IP in the net of update ISP be downloaded by special network management path
Address field set；(3) some user terminal gateway equipment vendors have set up web server, and provide ISP in advance on the internet
Address field is downloaded, and later stage user can pass through IP address section set in network online updating net.
As shown in Fig. 2, on the basis of any of the above-described embodiment of the method, before step S101, further include：
Step S10 obtains the domain name mapping result that higher level LDNS is returned；
Step S100, judges whether higher level LDNS has IP address priority ranking function；If having, step is performed
Message is replied in S201, the IP address priority orders generation directly returned by higher level LDNS；If not having, perform step S101 and
Step S102.That is, when higher level LDNS has priority ranking function, user terminal gateway equipment without carrying out IP address again
Identification and sequence directly using " inheriting parent LDNS sequences " mechanism, inherit the IP address priority of higher level's LDNS response messages
Sequentially, the delay of DNS request and response is reduced, and can ensure that operator Local DNS dispatch accuracy.
