Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further elaborated.
Embodiments of the invention store the static data in the host node of website into each branch node, and the GSLB server by host node, with user terminal to the flowing of access of host node be distributed to the nearest branch node of user terminal on, make user terminal directly obtain static data from nearest branch node, improved the speed that user terminal obtains static data, and the flowing of access to host node is shunted, alleviated the work of treatment amount of host node, thereby the rate of breakdown when having reduced the user terminal access website has improved the hit rate of user terminal access website.
As shown in Figure 1, Fig. 1 is the distribution method flow chart of a kind of static data of the embodiment of the invention, and this method may further comprise the steps:
Step S101, host node receives the static data request that user terminal sends.
User terminal need send the static data request to the host node of this website if certain website of visit obtains static data information from this website.This static data comprises time-independent data such as static page, picture, Voice ﹠ Video.User terminal sends the static data request to its local dns (Domain Name Server, name server) server, and then, local dns server is forwarded to this static data request on the dns server of website host node.
Step S102, this host node will send to this user terminal with the nearest branch node address of user terminal.
After the dns server of host node receives the static data request, this static data request is redirected to GSLB (Global Server Load Balancing, the GSLB server) server of host node.Then, the GSLB server is according to the address of user terminal, search branch node nearest in each branch node with this user terminal, to send to the dns server of user terminal with the nearest branch node address of user terminal, this dns server returns to user terminal with above-mentioned branch node address again.
Step S103, user terminal obtains static data from this branch node.User terminal directly obtains above-mentioned static data from this branch node according to the branch node address that receives, and comprises static page, picture, Voice ﹠ Video etc.User terminal directly sends the static data request to this branch node, if the static data that exists user terminal to ask on this branch node, then this branch node sends to this user terminal with the static data of user terminal requests.
But in actual applications, each branch node often only stores the part static data in the host node, for the consideration of saving cost and improving resource utilization, each branch node only should the zone in the user terminal static data of often visiting be stored in the branch node.Therefore, the static data of user terminal requests can appear, non-existent situation in branch node.Consider this kind situation, after branch node receives the static data request of user terminal transmission, at first judge the static data that whether stores user terminal requests in this branch node, if store the static data of user terminal requests in this branch node, then this branch node directly sends to user terminal with this static data; If do not store the static data of user terminal requests in this branch node, then this branch node obtains the static data and the storage of user terminal requests from host node, then this static data is sent to user terminal, and do not need user terminal can obtain the static data of needs again to the request of host node transmission static data.And, after branch node is stored this static data,, then can directly obtain this static data, thereby improve the speed that user terminal obtains data from this branch node if user terminal sends the request of this static data again to branch node.
Below in conjunction with schematic diagram shown in Figure 2, the embodiment of the invention described above is further elaborated.As shown in Figure 2, host node and branch node 1, branch node 2, branch node 3 have constituted a CDN (Content Delivery Network, content distributing network) jointly.
User terminal sends the request of visit image.taobao.com by the browser access website, and request obtains the IP address of image.taobao.com, and this request is by on the local dns server that user terminal is sent to this user terminal links to each other.
Local dns server is forwarded to this request on the dns server of image.taobao.com website host node again, because this website host node is by the GSLB server visit of user terminal to be dispatched, so the dns server of host node is redirected to this request on the GSLB server of host node.
The GSLB server of host node is by default operation rule, and according to the IP address of user terminal and the IP address of each branch node, calculate the branch node nearest with this user terminal, the IP address of this branch node that will calculate sends to the dns server that links to each other with user terminal then, is transmitted to user terminal by dns server again; Suppose that CDN comprises host node and branch node 1, branch node 2, branch node 3, the GSLB server of host node by default operation rule calculate with the nearest branch node of this user terminal be branch node 3, then the GSLB server sends to the dns server that user terminal links to each other with the IP address of branch node 3, is transmitted to user terminal by dns server again.
After user terminal receives the IP address of branch node 3, directly send the picture request to this branch node 3, if there is the pictorial information of user terminal needs in the branch node 3, then directly this pictorial information is sent to user terminal, if there is not the pictorial information of user terminal needs in the branch node 3, then branch node 3 obtains this pictorial information and storage from host node, then this pictorial information is sent to user terminal.And, after branch node 3 is stored this pictorial information,, then can directly get access to this pictorial information, thereby improve the speed that user terminal obtains pictorial information from branch node 3 if user terminal sends the request of these pictorial informations again to branch node 3.
The embodiment of the invention described above, user terminal is diverted to each branch node to the central access of host node, make user terminal obtain static data, alleviated the storage pressure of host node, also improved the user terminal access website and obtained the speed of static data from nearby branch node; Flowing of access to host node is shunted, and has alleviated the work of treatment amount of host node, thereby the rate of breakdown when having reduced the user terminal access website has improved the hit rate of user terminal access website.
In addition, embodiments of the invention also can be according to the growth pattern of user terminal access website traffic the quantity of corresponding expansion branch node, in for example embodiment illustrated in fig. 2, because the rapid increase of user terminal access flow, only branch node 1, branch node 2 and branch node 3 can not satisfy the visit needs of user terminal again among the feasible existing CDN, therefore can be according to the flowing of access growth pattern of user terminal, suitably increase the quantity of branch node among the CDN, thereby make CDN have stronger extensibility, can tackle the needs of user terminal access traffic growth.
In addition, embodiments of the invention also have stronger flexibility, and the host node of CDN can be controlled the flow of each branch node according to actual conditions.It still is example with embodiment illustrated in fig. 2, if because branch node 3 is upgraded or is broken down and temporarily can't provide service for user terminal, then host node can be dispatched by the GSLB server, with the assignment of traffic of branch node 3 to other branch nodes, thereby guarantee user terminal under impregnable situation, normal access websites.
The embodiment of the invention also provides a kind of dissemination system of static data, as shown in Figure 3, comprising: user terminal 100, host node 200 and branch node 300.
Wherein, user terminal 100 is used for sending the static data request to host node 200.User terminal 100 sends the static data request to coupled local domain name server, by local domain name server this static data request is forwarded to the name server of host node 200 then.
Fig. 4 is the effect schematic diagram of the embodiment of the invention.As shown in Figure 4, the flow of 100% expression user terminal access branch node A, the GSLB server is dispatched flow, the bandwidth gain of supposing front-end server is 80%, when also being user terminal access branch node A, hit rate to front-end server is 80%, then there is 80% user terminal access flow to handle by front-end server, 20% flow can't be handled by front-end server, this remaining 20% flow is then handled by back-end server, the bandwidth gain of supposing back-end server is 50%, when also being user terminal access branch node A, hit rate to back-end server is 50%, and then also remaining about 10% flow is that back-end server can't be handled, and this remaining about 10% flow is then finally handled by host node.Can find out that thus embodiments of the invention greatly reduce the treating capacity of host node by the user terminal access flow is shunted, the rate of breakdown when having reduced the user terminal access website has also improved the hit rate of user terminal access website.
In sum, the embodiment of the invention is diverted to each branch node with user terminal to the central access of host node, make user terminal obtain static data, alleviated the storage pressure of host node, also improved the user terminal access website and obtained the speed of static data from nearby branch node; Flowing of access to host node is shunted, and has alleviated the work of treatment amount of host node, and the rate of breakdown when having reduced the user terminal access website has improved the hit rate of user terminal access website.In addition, embodiments of the invention also have stronger flexibility and extensibility.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
