Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to thisBright being described in further detail, obviously, described embodiment is only a part of embodiment of the present invention,Instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not doingGo out all other embodiment that obtain under creative work prerequisite, all belong to the scope of protection of the invention.
Fig. 2, the domain name analytic method flow chart providing for the embodiment of the present invention. Referring to Fig. 2, the method bagDraw together:
S201, domain name mapping optimization device enter the DNS daily record in the home domain name system DNS period 1Row is analyzed, and determines the domain name list that needs optimization; Wherein, the described domain name list that needs optimization refers toIn period 1, the set of scheduling domain name devious, forwards S202 to.
The time span of above-mentioned period 1 can be set to 24 hours.
S202, according to the domain name in domain name list to authorize DNS initiate N the first recurrence request, receiptsTo authorizing after the response result of DNS for domain name, described in described response result is screened and obtainedThe analysis result that domain name is corresponding, and preserve domain name and corresponding analysis result, forward S203 to.
The second recurrence request that S203, reception local dns are initiated, described the second recurrence request comprises to be treatedThe domain name of access, forwards S204 to.
S204, judge in the domain name of preserving and corresponding analysis result whether exist and described domain name to be visitedThe domain name matching, if exist and described domain name phase to be visited in the analysis result of the domain name of preserving and correspondenceThe domain name of coupling, forwards S205 to; If in the domain name of preserving and corresponding analysis result, do not exist with described in treatThe domain name that the domain name of access matches, finishes.
S205, will send to described local dns with the corresponding analysis result of the described domain name matching.
In above-mentioned steps S201, dispatch domain name devious and refer to that this domain name analytically in DNS daily recordLocation comprises on-net location and the outer address of net. For example, mobile phone users is at the local dns server in ShanghaiOn carry out the access of domain name www.sina.com, if authorization server returns to this mobile phone usersIP (InternetProtocol, the agreement interconnecting between network) address is the IP that mobile operator has sometimesAddress, is not the IP address that mobile operator has sometimes, for example, is telecommunications operator or UNICOM's fortuneThe IP address that the business of battalion has, domain name mapping optimization device can be deposited above-mentioned domain name www.sina.comIn the domain name list that enters to need to optimize.
In above-mentioned steps S202, initiate N recurrence request according to the domain name in domain name list to mandate DNS,Receiving after the response result of mandate DNS for domain name, described response result is screened and obtainedThe analysis result that domain name is corresponding, and preserve domain name and corresponding analysis result, in the specific implementation, N getsValue can be set to 50. For example, domain name list only comprise a domain name www.sina.com andWww.baidu.com, domain name mapping optimization device is according to domain name www.sina.com and www.baidu.comTo authorizing 50 recurrence requests of the each initiation of DNS.
Further, receiving that after M the response result of mandate DNS for domain name, the value of M canBe 50, then judge M should be with in result whether have on-net location, if there is on-net location, willDescribed on-net location is as analysis result corresponding to domain name; In the time there is multiple on-net location, from multiple netsIn interior address, choose the on-net location that meets screening strategy most as analysis result corresponding to domain name.
Below only to comprise a domain name www.sina.com in domain name list to obtaining DNS from authorizingHow response result screens is described in detail, for convenience of description for the purpose of, suppose domain name mapping optimizationDevice to authorizing DNS to initiate 5 recurrence requests, is supposed 5 recurrence requests with domain name www.sina.comThe response result obtaining is respectively: (1) mobile IP address is: 192.168.1.110, the IP of (2) telecommunicationsAddress is: 202.168.1.110; (3) the IP address of UNICOM is: 201.168.1.110, the IP of (4) Tie TongAddress is: 192.168.1.109; (5) mobile IP address is: 192.168.1.100. When domain name mapping excellentWhen makeup is set to mobile operator and uses, the order that can arrange be 192.168.1.110,192.168.1.100,192.168.1.109; In the time screening, can be by equal the IP address of telecommunications and UNICOMAbandon, also can be sorted according to default rule in the IP address of telecommunications and UNICOM, for example, defaultRule be UNICOM after first telecommunications, or telecommunications after first UNICOM. Further hypothesis is by the IP of telecommunications and UNICOMAddress all abandons, and the order after screening is 192.168.1.110,192.168.1.100,192.168.1.109,In the specific implementation, the domain name after domain name and screening can be set up to a mapping relations table, for example, according toThe form that mapping relations between domain name www.sina.com and above-mentioned response result can be set up is as table belowShown in one:
Table one
Further, within each second round, initiate N according to the domain name in domain name list to mandate DNSInferior the first recurrence request; It is that time of second round is long that caching period of second round and local dns is identicalDegree is identical with the TTL (TimeToLive, life span) of cache module, under normal circumstances, and acquiescenceLife span is 3600 seconds (1 hour), represents caching server preservation in the time that the value of TTL is 3600 secondsThe time of the dns resolution result of having asked is 1 hour; When the time span of second round is set to 3600When second, represent just to initiate N recurrence to mandate DNS according to the domain name in domain name list every one hourRequest.
Further, terminal is initiated domain name mapping request to local dns, and this domain name mapping request comprisesDomain name to be visited; If there is not the solution matching with domain name to be visited in the current buffer memory of local dnsAnalyse result, local dns is initiated recurrence request to domain name mapping optimization device and mandate DNS. For example,Terminal use sends domain name mapping request to local dns, and domain name mapping request comprises domain name to be visited, asTerminal use need to access BAIDU website, and domain name mapping request comprises: www.baidu.com, if thisGround DNS preserves the IP address 202.108.98.132 that www.baidu.com is corresponding, local dns serviceCorresponding IP address 202.108.98.132 is sent to terminal use by device; If local dns is not preserved correspondenceIP address, local dns to domain name mapping optimization device and authorize DNS initiate recurrence request simultaneously,Suppose to preserve domain name www.baidu.com in the domain name list of domain name mapping optimization device, due to mandateDNS is conventionally distant from local dns, and therefore, local dns can preferentially be received domain name mapping optimization dressPut the analysis result of feedback.
