Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
Many data centers of the disclosed a kind of strange land of embodiment of the present invention cloud optimal storage access configuration method, comprises the following steps:
Receive the access request that cloud dish client Xiang Yunpan data center sends, and the ip address that obtains described cloud dish client host;
According to the ip address of described cloud dish client host, retrieval cloud dish server database also draws ip address, optimum visit data center, is then returned to described cloud dish client;
Receive ip address, described optimum visit data center, and contrast with the storing value in local data base, if identical, keep described storing value constant; If not identical, to receive described in upgrading described storing value and being ip address, optimum visit data center.
With reference to figure 1, it is the flow chart of many data centers of a kind of strange land of embodiment of the present invention cloud optimal storage access configuration method.The optimum access configuration method flow of the embodiment of the present invention is as follows:
Step 101: receive the access request that cloud dish client Xiang Yunpan data center sends, and the ip address that obtains described cloud dish client host.
User opens cloud dish client on individual main frame, and cloud dish client Hui Xiang Yi Geyunpan data center sends access request.User, be while using first cloud dish client, the Yun Pan data center of above-mentioned access is the Yun Pan data center of an acquiescence; User is non-while using first cloud dish client, the Yun Pan data center of above-mentioned access is the not necessarily optimum visit data center of this access of ，Dan Gai data center of data center corresponding to the ip of the Yi Ge data center address of storing in local data base.
Step 102: according to the ip address of described cloud dish client host, retrieval cloud dish server database also draws ip address, optimum visit data center, is then returned to described cloud dish client.
Wherein, described cloud dish server database is asked the ip of the data center mapping (enum) data of address for memory access main frame ip address and its optimum.According to being erected at the ip address date distributing in the local area network (LAN) of different geographical, and the ip address date that provides of heterogeneous networks access carrier, set up the mapping (enum) data of the ip address, optimum visit data center that above-mentioned ip address date is corresponding with it, and be stored in the cloud dish server database of network terminal i.e. storage: the mapping relations between access ip address and the optimum visit data center ip address corresponding with it.
Concrete optimum visit data center ip address generating method is: according to the ip address of described cloud dish client host, in described cloud dish server database, whether retrieval there is the optimum visit data center ip address corresponding with it, if so, this ip address, optimum visit data center is returned; If not, the ip of the data center address of current accessed is returned.
When not retrieving in cloud dish server database when accessing ip address, optimum visit data center corresponding to main frame ip address, the data center's acquiescence of this access of usining is returned as the ip address of optimum visit data center ，Jiang Gai data center.
Step 103: receive ip address, described optimum visit data center, and contrast with the storing value in local data base, if identical, trigger step 104; If not identical, trigger step 105.
Step 104: keep described storing value constant.
Step 105: the ip address, optimum visit data center receiving described in upgrading described storing value and being.
By the ip address, optimum visit data center obtaining in step 102, be stored in local data base, when user opens cloud dish client later again, first the ip address, optimum visit data center of local data library storage will be read, and access this data center, while making cloud dish client again access Yun Pan data center, directly access the ip address, optimum visit data center of described local data base storing value.When user accesses Yun Pan data center at every turn, all can carry out each step of the present embodiment; While carrying out step 103 and subsequent step, ip address, optimum visit data center that network terminal is generated is real-time is updated to local data base, make when user has changed network insertion place, can upgrade fast the optimum visit data center that is directed to current main frame ip address based on each access, guarantee user's optimum access.
If client's routine office work place is in Beijing, method through the present embodiment, for user rs host has configured the optimum visit data center that is positioned at Pekinese, client's temporary needs goes to Shanghai to go on business, and by the mass data data storage Yun Pan data center that needs in the process of going on business to use; Client arrives at behind the job site in Shanghai, the cloud dish client of opening on main frame logs in Yun Pan data center, the configuration of the method for process the present embodiment, storing value in main frame local data base is updated to the Yun Pan data center that is positioned at Shanghai, client from current optimal data center downloading data data, finishes the work fast smoothly; When going on business, finish client when getting back to routine office work place, Pekinese and logging in Yun Pan data center, before being updated to when the method by the present embodiment is again by optimal data center, be positioned at Pekinese Yun Pan data center, convenient and swift.
As an embodiment, the rear step 106 that further comprises of step 105: the ip address, described optimum visit data center receiving is updated to local hosts file.Cloud dish client is generally pc client or browser client.When using browser client, by the ip address of first determining that by reading hosts file Yun Pan data center domain name is corresponding, by this step, the local hosts file medium cloud dish corresponding parsing of data center's domain name ip address is updated to the ip address, optimum visit data center receiving, has realized the configuration of the optimum access of Yun Pan data center while using browser client.
The embodiment of the invention also discloses many data centers of a kind of strange land cloud optimal storage access configuration device, comprising:
