Abstract
The invention discloses a routing address switching method and device. The method comprises the following steps: issuing the same IP (Internet Protocol) addresses by a plurality of Internet data center IDC internal domain name analysis systems, and issuing same IP addresses by a network spanning across the IDCs; uniformly configuring domain name resolution service IP addresses of business equipment in the systems; when any one of the IDC internal domain name analysis systems has faults, obtaining a routing address of a normal ICD by the system which has the faults; switching the routing address of the system which has the faults to the routing address of the normal ICD according to the obtained routing address. By virtue of the routing address switching method and device, the routing address can be intelligently and dynamically switched when the domain name analysis systems have faults, and the reliability of domain name systems is improved.
Description
Technical field
The present invention relates to internet domain name field, specifically, relate to a kind of routing address changing method and device.
Background technology
Current, along with the extensive use of ecommerce, all can there be multiple different regions IDC (Internet Data Center in major part enterprise, Internet data center), every station server all must configure DNS (Domain Name System, domain name system) service IP and be used for domain name mapping.But, when whole domain name analysis system is abnormal in the IDC, but there is no a kind of intelligence and highly reliable technology solves this fault.
In the prior art, a kind of processing mode is: the domain name analysis system of each IDC issues different VIP (Virtual IP Address respectively, virtual ip address) domain name mapping is provided, then Servers-all configuration all only configures the VIP of this machine room domain name analysis system, only resolve in this IDC inside in any case, this processing mode makes all parsings only inner at this IDC, the problem of resolving across machine room can not be caused, but when this machine room domain name analysis system fault, the inner all server domain name analysis of whole IDC all will exception.Another kind of processing mode is: the domain name analysis system of each IDC issues different VIP respectively provides domain name mapping, and it is for subsequent use that the VIP that then Servers-all configures one or more machine room domain name analysis system configures one or more other machine room domain name analysis system VIP simultaneously.First each inquiry uses the VIP in this IDC region, attempts resolving inquiry across machine room VIP when failure, and a kind of this IDC of being uses with the domain name mapping VIP across IDC simultaneously.This processing mode has certain defect equally, and when this machine room domain name analysis system fault, domain name mapping request still can use the VIP of first fault to carry out domain name mapping, causes domain name mapping slower like this.The program uses the VIP across IDC to start most to configure to fix in addition, can not carry out intelligent selection parsing according to domain name analysis system load in current network resources, other IDC etc.
Therefore, in order to solve the problem, need a kind of intelligence based on dynamic routing protocol to switch the processing mode of routing address.
