Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present application clearer, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the application's protection.
Fig. 1 is the content routing method schematic flow sheet that one embodiment of the invention provides, and as shown in Figure 1, comprising:
101, the content requests of receiving terminal transmission, content requests is used to indicate the content resource that terminal request is obtained.
102, according to the indication of content requests, identify the type of content resource.
103, according to the weighted value of all kinds of service performance parameters corresponding to the type of content resource and the difference value of the corresponding same type of service performance parameter of each high-speed cache Cache servers, from each Cache servers, select to provide the destination server of content resource.
Wherein, the service performance parameter refers to the performance parameter of Cache servers, be used for to weigh the good and bad degree of performance of Cache servers, can be divided into different classes of, such as server load, CPU usage, network delay, stability and response time etc.
104, content requests is redirected to destination server.
Concrete, the content requests that receiving terminal sends, the type of the content resource of identification content requests indication.According to the difference value of the corresponding same type of service performance parameter of each Cache servers in the weighted value of all kinds of service performance parameters corresponding to the type of content resource and the network, obtain the selection weighted value of corresponding each Cache servers of type of content resource.Selection weighted value according to each Cache servers, select target server from each Cache servers, for example: by inquiring about each Cache servers, obtain the Cache servers with content resource, from the Cache servers with described content resource that obtain, select the Cache servers of weighted value maximum as described destination server; If do not inquire the Cache servers with content resource, then calculate the bandwidth that each Cache servers obtain the required consumption of content resource, the Cache servers of the bandwidth minimum of the required consumption of described content resource are obtained in selection, as described destination server.
In the present embodiment, by the indication according to content requests, the type of identification content resource, weighted value according to all kinds of service performance parameters corresponding to the type of content resource, difference value with the corresponding same type of service performance parameter of each Cache servers, from each Cache servers, select to provide the destination server of content resource, improved the server performance matching degree of server performance and the destination server of demanding terminal, and then improved the efficient that terminal is obtained content resource.
Fig. 2 is the content routing method schematic flow sheet that another embodiment of the present invention provides, and as shown in Figure 2, comprising:
201, the content requests of GSLB controller receiving terminal transmission, content requests is used to indicate the content resource that terminal request is obtained.
Concrete, terminal sends content requests, content requests comprises the sign of content resource and the URL(uniform resource locator) of content resource (Universal Resource Locator, URL), local or multistage computer domain name system (Domain Name System, DNS) server is resolved domain name according to content requests, obtain the address of source server, source server is redirected to the GSLB controller with content requests, the content resource that the content requests that the GSLB controller receives has indicated terminal request to obtain, for example: the sign by content resource is provided or the URL of content resource, the content resource of indicating terminal acquisition request.
The type correspondence of different content resources has required different server performances, and for example: the type of content resource is that file is downloaded, and the corresponding server performance that requires is that bandwidth is large and stability is higher; The type of content resource is Online Video, and the corresponding server performance that requires is that load is light, close together and response time are shorter.
202, judge whether to get access to the Cache servers with content resource.If can get access to the Cache servers with content resource, then carry out 203 to 207, if can not get access to the Cache servers with content resource, then carry out 208 to 209.
Concrete, inquiry has the Cache servers of content resource, judges whether to get access to the Cache servers with content resource.If judge the content resource that each Cache servers all do not have the content requests indication, then carry out 208 to 209, if judge the server that can inquire the content resource with content requests indication, carry out 203 to 207.By inquiring about each Cache servers, obtain the Cache servers with content resource, avoided because destination server obtains the content resource bandwidth consumed and produces time delay, further improved the efficient that terminal is obtained content resource.
Need to prove, the server list that GSLB can pre-stored indication Cache servers scope, Cache servers can be the part Cache servers in the network, also can be all Cache servers in the network, and present embodiment is not done restriction to this.
203, the GSLB controller is identified the type of content resource according to the indication of content requests.
Concrete, according to the sign of the content resource in the content requests or the URL of content resource, and the corresponding relation between the type of content resource, the type of identification content resource.Wherein, the sign of the content resource in the content requests or the memory address of content resource, and the corresponding relation between the type of content resource can be pre-stored on the GSLB controller.
204, the GSLB controller obtains the weighted value of all kinds of service performance parameters corresponding to the type of content resource.
