The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

The network device may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer. Network devices include, but are not limited to, computers, network hosts, a single network server, multiple sets of network servers, or a cloud of multiple servers.

Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a resource access method provided in an embodiment of the present application, taking a resource access device integrated in a network device as an example, when a terminal fails to access resources of a target network, the network device may obtain a current region of the terminal in the target network and current resource quality parameters corresponding to the current region, obtain resource quality parameters corresponding to multiple candidate regions in the target network, select a target region from the multiple candidate regions according to the current resource quality parameters and the resource quality parameters corresponding to the candidate regions, generate proxy server link information of a proxy server corresponding to the target region, and send the proxy server link information to the terminal, so that the terminal performs resource access according to the proxy server link information.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a resource access method according to an embodiment of the present application. The specific process of the resource access method provided by the embodiment of the application can be as follows:

201. when the terminal fails to access the resources of the target network, the current area of the terminal in the target network and the current resource quality parameters corresponding to the current area are obtained.

The target network may be a network deployed in a resource access system, the target network may include multiple areas, and the terminal may obtain the network resource required by the terminal by accessing the cache servers in the multiple areas in the target network. For example, the target network may be a content distribution network, the content distribution network may include a plurality of areas, and the terminal may access network resources of a cache server in an area in the target network, so as to achieve the purpose of playing a video or downloading a video.

The content distribution network can transmit network resources more quickly and more stably by avoiding the part which possibly influences the data transmission speed and stability on the internet. By arranging cache nodes in a plurality of areas in the content distribution network and forming an intelligent virtual network based on the existing Internet, the content distribution network can guide a terminal request to the cache node closest to the terminal in real time according to the acquired comprehensive information, wherein the comprehensive information can comprise network flow, connection and load conditions of each node, distance between the terminal and the comprehensive information, response time and the like. The terminal can obtain the required network resources nearby, thereby solving the phenomenon of congestion and blockage of the internet and improving the response speed when the terminal accesses the website. The content distribution network may include a source station, which may be a service server integrating the overall network resources, and several caching nodes located in multiple regions. Multiple levels of caching can be performed in several caching nodes, for example, the multiple levels of caching can further include a first level cache, a second level cache, and the like.

The resource quality parameter may be a parameter representing quality of a network resource, and the resource quality parameter may include multiple resource quality quantum parameters, for example, the resource quality parameter may include a resource download speed parameter, a resource play fluency parameter, and the like. In this embodiment, the resource quality parameter may be a parameter for measuring the quality of network resources in an area in the content distribution network, and the resource quality parameter may include a video downloading speed, an online video playing fluency, and the like.

In practical application, in order to replace the area where the terminal resource access fails to access the resource in time so that the terminal can normally access the resource, the current area of the terminal in the target network and the current resource quality parameter corresponding to the current area can be obtained when the terminal fails to access the resource of the target network. For example, when it is detected that the user cannot normally play or download a video, it may be considered that the terminal where the user is located fails to access network resources in the current area in the content distribution network, at this time, the current area where the terminal is located in the content distribution network may be obtained, and current resource quality parameters corresponding to the current area may be obtained, where the current resource quality parameters may include parameters such as a current video download speed of the current area and a current online video play fluency.

In an embodiment, the server may receive an information acquisition request from the terminal, where it may be described that an abnormality occurs when the terminal where the user is located accesses the current area of the content distribution network, and the server may acquire the current area where the terminal is located in the content distribution network and a current resource quality parameter corresponding to the current area according to the information acquisition request, so as to perform an area selection step according to the current resource quality parameter.

202. And acquiring resource quality parameters corresponding to a plurality of candidate areas in the target network.

In practical application, in order to obtain a plurality of candidate regions of a target network conveniently, resource quality parameters are better than quality candidate regions of a current region, and resource quality parameters corresponding to the plurality of candidate regions in the target network can be obtained. For example, a plurality of candidate areas included in the content distribution network and the resource quality parameter corresponding to each candidate area may be acquired, and since the content distribution network is configured by arranging node servers at various places in the network, the resource quality parameters corresponding to the plurality of candidate areas of the content distribution network are different.

203. And selecting a target area from the candidate areas according to the current resource quality parameter and the resource quality parameter corresponding to the candidate area.

In practical application, in order to meet the requirement that the terminal normally accesses network resources, a target region may be selected from a plurality of candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the candidate region. For example, because the access of the terminal to the network resource in the current area is abnormal, the server may obtain resource quality parameters corresponding to multiple candidate areas in the content distribution network, so as to compare the resource quality parameters corresponding to the candidate areas with the current resource quality parameters corresponding to the current area, and further select a resource quality parameter superior to the current resource quality parameter from the resource quality parameters corresponding to the multiple candidate areas, thereby achieving the purpose of selecting a target area from the multiple candidate areas.

In an embodiment, in order to enable the terminal to normally access network resources in a target area in a target network, a quality candidate area whose resource quality parameters meet a standard may be selected first, and then the target area selection step is performed, so as to improve the accuracy of target area selection. Specifically, the step of "selecting a target region from a plurality of candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the candidate region" may include:

selecting a quality candidate region from a plurality of candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the candidate region;

and selecting a target area from the quality candidate areas.

In practical application, a quality candidate region may be selected from the multiple candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the candidate region, and a target region may be selected from the quality candidate region. For example, a region of the multiple candidate regions in which the resource quality parameter is better than the current resource quality parameter may be used as a quality candidate region, where the quality candidate region may be a unique region, and at this time, the unique quality candidate region may be used as a target region; when there are multiple quality candidate regions, the target region may be selected from the multiple quality candidate regions according to information such as a value of the resource quality parameter or a distance between the quality candidate region and the current region.

In an embodiment, the resource quality parameters may include a plurality of resource quality sub-parameters, so that by obtaining a parameter relationship between a plurality of resource quality sub-parameters corresponding to the resource quality parameters and a plurality of original resource quality sub-parameters corresponding to the original resource quality parameters, which resource quality parameters are better solutions may be defined, and further, a quality candidate region may be selected from the candidate regions. Specifically, the step of "selecting a quality candidate region from a plurality of candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the candidate region" may include:

acquiring a parameter value relation between a resource quality sub-parameter corresponding to the candidate region and a current resource quality sub-parameter;

and selecting a quality candidate region from the plurality of candidate regions according to the parameter value relation.

In practical application, the parameter value relationship between the resource quality sub-parameter corresponding to the candidate region and the current resource quality sub-parameter can be obtained, and the quality candidate region is selected from the multiple candidate regions according to the parameter value relationship. For example, the resource quality parameter may include a plurality of resource quality sub-parameters, such as video download speed, online video playing fluency, and the like. The larger the value of the video downloading speed is, the faster the video downloading speed can be shown, and the larger the value of the online video playing fluency is, the smoother the video playing can be shown. Therefore, when the resource quality parameters comprise two resource quality sub-parameters of video downloading speed and online video playing fluency, the areas with the video downloading speed higher than the original video downloading speed and the online video playing fluency higher than the original online video playing fluency can be obtained, and the resource quality of the areas is better than that of the current area, so that the area can be used as a quality candidate area.

If the value of the video downloading speed is greater than the original video downloading speed, but the value of the online video playing fluency is not greater than the original online video playing fluency, the candidate area is not considered to be the quality candidate area; correspondingly, if the value of the video downloading speed is not greater than the original video downloading speed, but the value of the online video playing fluency is greater than the original online video playing fluency, the candidate area can also be considered as not being the quality candidate area.

In an embodiment, when a plurality of quality candidate regions are obtained, a region with the optimal quality of resources in a target network can be obtained by fusing a plurality of resource quality quantum parameters, so that a user can normally access network resources, and the accuracy of obtaining the target region is improved. Specifically, the step of "selecting a target region from the quality candidate regions" may include:

fusing a plurality of resource quality quantum parameters corresponding to the quality candidate region to obtain fused resource quality information corresponding to the quality candidate region;

and selecting a target area from the quality candidate areas according to the quality information of the fusion resources.

In practical application, a plurality of resource quality quantum parameters corresponding to the quality candidate regions can be fused to obtain fusion resource quality information corresponding to the quality candidate regions, and a target region is selected from the quality candidate regions according to the fusion resource quality information. For example, when the resource quality parameter includes a plurality of resource quality quantum parameters, each resource quality quantum parameter may be given a weight, and then the plurality of resource quality quantum parameters are fused according to the weight corresponding to each resource quality quantum parameter, so as to obtain fused resource quality information corresponding to the resource quality parameter. After acquiring the fusion resource quality information corresponding to each quality candidate region, the quality candidate region with the largest value may be selected from the multiple pieces of fusion resource quality information as the target region. Therefore, the user can acquire the area with the optimal resource quality and access the network resources.

In an embodiment, in the content distribution network, the closer the network resource to the user is, the better the resource access effect is for the user, so that after a plurality of quality candidate areas are obtained, the accuracy of target area selection can be improved by calculating the separation distance. Specifically, the step of "selecting a target region from the quality candidate regions" may include:

obtaining the region interval distance between the region key point of each quality candidate region and the region key point of the current region;

and selecting a target area from the quality candidate areas according to the area spacing distance.

The area key point may be a key point representing an area position, and there may be a plurality of methods for selecting the area key point, for example, an area center point of the area may be used as the area key point, and for example, a position point where a content distribution network is deployed in the area and a cache server is located may be used as the area key point, and the like.

In practical application, the region interval distance between the region key point of each quality candidate region and the region key point of the current region can be obtained, and the target region is selected from the quality candidate regions according to the region interval distance. For example, after a plurality of quality candidate regions are obtained, a region key point corresponding to each quality candidate region and a region key point corresponding to the current region may be obtained, then, a region interval distance between the region key point corresponding to each quality candidate region and the region key point corresponding to the current region is calculated, where the region interval distance may be a straight-line distance between two region key points, and then, the quality candidate region with the shortest region interval distance may be selected as a target region, so that a user may access network resources in a region as close as possible to the user among the quality candidate regions.

In an embodiment, to avoid the problem of poor effect of accessing network resources by a user due to too far distance between a target area and a current area, a distance candidate area may be selected from a plurality of candidate areas of a target network, and then the target area may be selected from the distance candidate areas according to a resource quality parameter. Specifically, the resource access method may further include:

obtaining a distance candidate region in a target network, wherein the region interval distance between the target network and the region key point of the current region is within a preset distance range;

and selecting a target area from the plurality of distance candidate areas according to the current resource quality parameters and the resource quality parameters corresponding to the distance candidate areas.

In practical application, a distance candidate region in which the region interval distance between the target network and the region key point of the current region is within a preset distance range can be obtained, and the target region is selected from the multiple distance candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the distance candidate region. For example, a distance candidate region having a region separation distance from a region key point of the current region within a preset distance range may be first obtained, and the distance candidate region may satisfy a requirement of the terminal for the distance. Then, each resource quality sub-parameter corresponding to the distance candidate region may be given a corresponding weight, and fusion resource quality information corresponding to the distance candidate region may be calculated, and the target region may be set as the region having the largest value of the fusion resource quality information in the distance candidate region.

In an embodiment, if at least one distance candidate region cannot be acquired within a preset distance range, the preset distance range may be adjusted to acquire the target region. When only one distance candidate region is acquired within a preset distance range, the only distance candidate region may be used as a target region. In this way, the user can be enabled to access the network resource with relatively optimized resource quality within the distance allowable range.

204. And generating proxy server link information of the proxy server corresponding to the target area.

In practical applications, in order to enable the terminal to access network resources through the proxy server, proxy server link information of the proxy server corresponding to the target area may be generated. For example, after the target area is obtained, the proxy server corresponding to the target area may be determined, the area address corresponding to the target area and the server identifier corresponding to the proxy server are obtained, and the area address and the proxy server identifier are fused to obtain the link information of the proxy server.

In an embodiment, in order to enable the terminal to access the network resource in the target area in the target network through the proxy server, the proxy server link information may include an area address corresponding to the target area and a server identifier corresponding to the proxy server, so that accuracy of resource access is improved. Specifically, the step of "generating proxy link information of a proxy server corresponding to the target area" may include:

acquiring a regional proxy server mapping set, wherein the regional proxy server mapping set comprises mapping relations between a plurality of candidate regions in a target network and a proxy server;

determining a proxy server corresponding to the target area according to the area proxy server mapping set;

acquiring the area address of the target area and the server identification of the proxy server corresponding to the target area;

and generating proxy server link information of the proxy server corresponding to the target area according to the area address and the server identifier.

In practical applications, for example, a regional proxy mapping set including relationships between a plurality of candidate regions and proxy servers in a content distribution network may be first obtained, a proxy server corresponding to a target region may be determined according to the regional proxy mapping set, a region code of the target region, a region address of the target region, and a server domain name of the proxy server corresponding to the target region may then be obtained, and proxy link information may then be generated according to the obtained region code, region address, server domain name, and the like, where the proxy link information may be expressed as https:// proxy domain name? The area code XXX & CDN address XXX.

In an embodiment, after obtaining a plurality of quality candidate areas from a plurality of candidate areas of a target network, a plurality of candidate proxy server link information may be generated respectively and sent to a terminal, so that the terminal may select the target area according to a selection operation of a user. Specifically, after the step "selecting a quality candidate region from a plurality of candidate regions according to the current resource quality parameter and the resource quality parameter corresponding to the candidate region", the method may further include:

generating candidate proxy server link information of a proxy server corresponding to the quality candidate area;

and sending the candidate proxy server link information to a terminal.

In practical application, candidate proxy server link information of the proxy server corresponding to the quality candidate area can be generated, and the candidate proxy server link information is sent to the terminal. For example, after a plurality of quality candidate areas are acquired, candidate proxy server link information of a proxy server corresponding to each quality candidate area may be generated, and the candidate proxy server link information may be sent to the terminal, so that the terminal may select a target area according to a selection operation of a user.

205. And sending the link information of the proxy server to the terminal so that the terminal can access resources according to the link information of the proxy server.

In practical application, the proxy server link information may be sent to the terminal, so that the terminal performs resource access according to the proxy server link information. For example, the server may send the proxy server link information to the terminal, and the terminal may replace the content distribution network link of the current area according to the proxy server link information, so that the terminal performs access to the network resource.

In an embodiment, as shown in fig. 7, for example, a user a located in a user area a may successfully access a network resource in a content delivery network, but a user B located in a user area B may not normally access the network resource in the content delivery network, at this time, the user B may connect to a proxy server, so that the proxy server accesses the CDN of a target area, and then the user B may normally access the network resource.

As can be seen from the above, in the embodiment of the present application, when a terminal fails to access resources of a target network, a current area of the terminal in the target network and current resource quality parameters corresponding to the current area are obtained, resource quality parameters corresponding to a plurality of candidate areas in the target network are obtained, according to the current resource quality parameters and the resource quality parameters corresponding to the candidate areas, a target area is selected from the candidate areas, proxy server link information of a proxy server corresponding to the target area is generated, and the proxy server link information is sent to the terminal, so that the terminal accesses the resources according to the proxy server link information. According to the scheme, the terminal and the target area in the target network can be automatically matched, and the terminal in the current area in the abnormal state is proxied to the target area in the normal state for resource access in a proxy mode, so that the content availability problem of the candidate area in the abnormal state in the target network can be solved without participation of a website operator, the operation quality of a website and the resource access experience of a user are improved, and meanwhile, the initiative of a browser platform for controlling the operation quality of the website can be enhanced through the resource access method.

The method described in the foregoing embodiment will be described in further detail below by way of example in which the resource access device is specifically integrated in a network device.

Referring to fig. 3, a specific process of the resource access method according to the embodiment of the present application may be as follows:

301. and when the terminal fails to access the network resources in the current area in the content distribution network, sending an information acquisition request to a background server.

In practical applications, for example, as shown in fig. 6, when a user fails to play a video or download a video, it is indicated that an abnormality occurs when a terminal where the user is located accesses a network resource in a current area in a content distribution network, at this time, the terminal may send an information acquisition request to a background server, and query the background server through the information acquisition request whether a candidate area corresponding to a resource quality parameter better than a current resource quality parameter in the current area exists.

In an embodiment, for example, as shown in fig. 5, when a user successfully plays a video or successfully downloads a video, the terminal may obtain a current resource quality parameter corresponding to a current area where the terminal is located, and information such as a current exit gateway, where the current resource quality parameter includes a video downloading speed and an online video playing fluency. When the user finishes playing the video or downloading the video, the obtained information of the current resource quality parameter, the current exit gateway and the like can be reported to the background server, and after the background server obtains the reported information, the information of the resource address, the current region, the current resource quality parameter and the like corresponding to the current resource quality parameter can be stored, and the history stored information is updated according to the newly obtained information.

302. And the background server acquires the current area of the terminal in the content distribution network and the current resource quality parameter corresponding to the current area according to the information acquisition request.

In practical applications, for example, the background server may obtain a current area where the terminal is located in the content distribution network according to an information obtaining request sent by the terminal, and obtain current resource quality parameters corresponding to the current area, where the current resource quality parameters may include parameters such as a current video downloading speed of the current area and a current online video playing fluency.

303. The background server acquires resource quality parameters corresponding to a plurality of candidate areas in the content distribution network.

In practical applications, for example, the background server may obtain a plurality of candidate areas included in the content distribution network and resource quality parameters corresponding to each candidate area according to an information obtaining request sent by the terminal, and since the content distribution network is formed by arranging node servers at various places in the network, the resource quality parameters corresponding to the plurality of candidate areas of the content distribution network are different.

304. And the background server selects a target area from the candidate areas according to the current resource quality parameters and the resource quality parameters corresponding to the candidate areas.

In practical application, the background server may select a target area with better resource quality than a current area from a plurality of candidate areas in the content distribution network. For example, the background server may select, from a plurality of candidate areas of the content distribution network, an area in which the video download speed is higher than the original video download speed and the online video play fluency is higher than the original online video play fluency as the quality candidate area. When the quality candidate region is a unique region, the unique quality candidate region may be taken as a target region; when there are a plurality of quality candidate regions, a region separation distance between each quality candidate region and the current region may be calculated, and the quality candidate region in which the region separation distance is the smallest may be taken as the target region.
