Background
With the rapid development of science and technology, people use intelligent terminal devices more and more frequently, and users can acquire various resources such as video files, audio files and the like through various intelligent terminal devices such as mobile phones, computers, intelligent televisions and the like to download or cache. When a user needs to acquire resources, a request for acquiring the resources is sent to a Content Delivery Network (CDN) system through an intelligent terminal device, so that the CDN system pushes the resources to the user through an edge node of the CDN system according to the request for acquiring the resources.
However, when pushing resources to a user via an edge node, a fee is needed for use, and the main fee is a usage fee of bandwidth, and the higher the utilization rate of the bandwidth, the higher the cost is. Bandwidth charges in most cases are generated substantially during periods of high bandwidth utilization, such as 11:00-14:00 pm peak periods and 18:00-23:00 late peak periods.

S102: detecting whether a preset data resource corresponding to the resource information and sent by a Content Delivery Network (CDN) system is cached in the front-end caching device or not;
in the embodiment of the present invention, after the front-end caching device obtains the resource information corresponding to the resource request, it is detected whether the intelligent caching device has cached the data resource corresponding to the resource information. The cached data resources corresponding to the resource information are data resources sent to the pre-caching device for caching by the Content Delivery Network (CDN) system.
S103: if the data resource corresponding to the resource information and sent by the CDN system is cached in the preposed caching equipment, pushing the data resource corresponding to the resource information to the user;
in the embodiment of the present invention, the pre-caching device detects whether the data resource corresponding to the resource information is cached according to the resource information. And if the data resource is cached, pushing the data resource corresponding to the resource information to the user.
When it is required to be noted, the data resource may be a movie resource, a text resource, a photo resource, and other data resources.
S104: if the data resources corresponding to the resource information and sent by the CDN system are not cached in the front-end cache device, sending the resource information to the CDN system, and triggering the CDN system to search resources according to the resource information;
in the embodiment of the present invention, if the data resource corresponding to the resource information is not cached in the pre-cache device. The front-end cache device sends a request message for acquiring data resources to the CDN system, and sends the resource information to the CDN system so that the CDN system searches resources according to the resource information sent by the front-end cache device.
S105: and when receiving the data resource corresponding to the resource information fed back after the resource search is performed by the CDN system, storing the data resource corresponding to the resource information, and pushing the data resource to the user.
In the embodiment of the present invention, after the CDN system searches according to the resource information, the data resource corresponding to the resource information is fed back to the pre-cache device. The front-end cache device can send the data resource corresponding to the resource information to the user according to the data resource fed back by the CDN system.
It should be noted that the pre-cache device stores the data resource corresponding to the resource information sent by the CDN system, and when the user requests to obtain the same data resource again, the pre-cache device may push the data resource to the user according to the cached data resource without passing through the CDN system, thereby reducing the bandwidth utilization.
In the method provided by the embodiment of the invention, the preposed cache equipment receives the resource request sent by the user. And acquiring resource information corresponding to the resource request according to the resource request sent by the user. And according to the resource information, the preposed cache equipment detects whether the data resource corresponding to the resource information is cached or not. And if the preposed caching equipment caches the data resource corresponding to the resource information, sending the data resource corresponding to the resource information to the user. The cached data resources corresponding to the resource information are data resources sent to the pre-cache device by the CDN system before the user sends the resource request to the pre-cache device, and the pre-cache device may cache various data resources sent by the CDN system. And if the data resource corresponding to the resource information is not cached in the front-end cache device, the front-end cache device sends the resource information to the CDN system, and the CDN system searches the resource according to the resource information sent by the front-end cache device. When the front-end cache device receives the data resource corresponding to the resource information and fed back by the CDN system after searching the resource, the front-end cache device stores the data resource corresponding to the resource information and sent by the CDN system, and meanwhile, the data resource is pushed to the user.
It should be noted that, when the pre-caching device has cached the data resource required by the user, the pre-caching device may directly push the data resource to the user, and the pre-caching device does not need to push the data resource through network communication in the process of pushing the data resource to the user. When the communication is unstable or the CDN system is abnormal, the pre-caching device can still push the cached data resource to the user in time, so as to greatly improve the experience of the user in obtaining the data resource and further reduce the bandwidth utilization.
Optionally, when the front-end cache device does not cache the data resource corresponding to the resource information, the resource information is sent to the CDN system, and after the CDN system performs resource search according to the resource information sent by the front-end cache device to obtain the data resource corresponding to the resource information, the searched data resource may be directly sent to the user, and at this time, the front-end cache device is not needed.
The resource pushing method provided by the embodiment of the invention can be applied to various fields, for example, in the field of video pushing, and can be used for pushing video resources to videos which are required to be watched by users. By applying the method provided by the embodiment of the invention, the front-arranged cache equipment acquires the video information corresponding to the video resource request after receiving the video resource request sent by the user. And detecting whether video resources corresponding to the video information are cached in the front cache equipment or not according to the video information. And if the video information is cached, pushing the video resource corresponding to the video information to the user. And if the video information is not cached, sending the video information to the CDN system, and searching resources by the CDN system according to the video information. And if the CDN system searches the video resource corresponding to the video information, sending the video resource to the front-end cache device, and storing the video resource by the front-end cache device and pushing the video resource to the user.
By applying the method provided by the embodiment of the invention, the preposed cache equipment can cache the data resource in advance, when the resource request is received, the preposed cache equipment pushes the data resource to the user without pushing the data resource to the user by the CDN system, so that the utilization rate of the bandwidth is reduced and the bandwidth cost is saved during the peak time period of the bandwidth use.
In the method provided in the embodiment of the present invention, based on step S102, after the pre-cache device obtains the resource information corresponding to the resource request, it needs to detect whether the pre-cache device has cached the data resource corresponding to the resource information sent by the CDN system, and a specific detection process is shown in fig. 2 and specifically includes:
s201: acquiring a resource name contained in the resource information;
in the embodiment of the present invention, the resource information corresponding to the resource request sent by the user includes the resource name corresponding to the resource required by the user.
S202: detecting whether a data resource name corresponding to the resource name exists in the preposed cache equipment or not;
in the embodiment of the present invention, the pre-cache device detects whether a data resource name corresponding to the resource name exists according to the resource name included in the resource information.
Note that the data resource name corresponding to the resource name means that the resource name coincides with the data resource name. The resource name is a resource name included in the resource information when the user sends the resource request, and the data resource name is a data resource name corresponding to the data resource cached in the pre-caching device.
S203: when a data resource name corresponding to the resource name exists in the pre-caching device, determining that a data resource corresponding to the resource information and sent by the CDN system is cached in the pre-caching device;
in the embodiment of the present invention, when the data resource name of one data resource existing in the pre-caching device is consistent with the resource name included in the resource information, that is, when the data resource name corresponding to the resource name exists in the pre-caching device, it is determined that the data resource corresponding to the resource information is cached in the pre-caching device. The data resource is a data resource which is sent to the preposed cache device by the CDN system in advance.
S204: when the data resource name corresponding to the resource name does not exist in the pre-caching device, determining that the data resource corresponding to the resource information and sent by the CDN system is not cached in the pre-caching device.
In the embodiment of the present invention, when the data resource name of one data resource does not exist in the pre-caching device is consistent with the resource name included in the resource information, that is, when the data resource name corresponding to the resource name does not exist in the pre-caching device, it is determined that the data resource corresponding to the resource information is not cached in the pre-caching device.
In the resource pushing method provided in the embodiment of the present invention, the pre-caching device first obtains the resource name included in the resource information, and detects whether the data resource name corresponding to the resource name exists according to the resource name. If the data resources exist, the prepositive caching device is proved to have cached the data resources which are sent by the CDN system in advance and correspond to the resource information, so that the prepositive caching device can push the cached data resources to the user; if the data resource does not exist, the prepositive caching device is proved not to cache the data resource which is sent by the CDN system in advance and corresponds to the resource information, so that the prepositive caching device obtains the data resource which corresponds to the resource information through the CDN system, caches the data resource and pushes the data resource to the user.
By applying the method provided by the embodiment of the invention, whether the preposed cache equipment caches the data resource corresponding to the resource information is detected through the resource name, so that the preposed cache equipment can more accurately acquire the data resource required by the user and push the data resource to the user, thereby reducing the utilization rate of bandwidth and reducing the cost of the bandwidth.
In the method provided in the embodiment of the present invention, based on step S104, when the pre-cache device does not cache the data resource corresponding to the resource information, the pre-cache device sends the resource information to the CDN system, which specifically includes:
judging whether the front-end cache device has a connection right for establishing communication connection with the CDN system;
when the pre-cache device has the connection right for establishing communication connection with the CDN system, establishing the communication connection between the pre-cache device and the CDN system, and sending the resource information to the CDN system;
when the pre-cache device does not have the connection right for establishing communication connection with the CDN system, sending a prompt message for requesting communication connection with the CDN system to the user;
and if an authorization message which is given by the user to establish communication connection with the CDN system according to the prompt message feedback and is granted to the front-end cache device is received, establishing communication connection with the CDN system, and sending the resource information to the CDN system.
In the resource caching method provided by the embodiment of the invention, when the pre-caching device sends the resource information to the CDN system, whether the pre-caching device has the connection right for communication connection with the CDN system is judged. When the connection right for communication connection with the CDN system is provided, when the resource information is sent to the CDN system, communication connection with the CDN system is established, and after the communication connection, the resource information is sent to the CDN system. The current cache device does not have the connection permission for communication connection with the CDN system, a prompt message for requesting to establish communication connection with the CDN system is sent to a user, and the user selects whether to grant the permission for communication connection between the current cache device and the CDN system. When the pre-cache system receives an authorization message which is sent by a user and is in communication connection with the CDN system, communication connection is established with the CDN system according to the authorization message, and resource information is sent to the CDN system.
Optionally, when the pre-cache device receives an authorization rejection message sent by the user and communicatively connected to the CDN system, the pre-cache device may not send the resource information to the CDN system, but directly feed back a prompt message indicating that the resource acquisition has failed to the user, so that the user grants the pre-cache device to establish a communication connection with the CDN system again or the user directly sends a resource request to the CDN system.
It should be noted that a communication connection also needs to be established between the user and the pre-cache system, after the communication connection is established, the user may send the resource request to the pre-cache device, otherwise, the user directly sends the resource request to the CDN system.
By applying the method provided by the embodiment of the invention, the communication connection between the preposed cache device and the CDN system is established, so that the data resource required by the user can be obtained from the CDN system when the preposed cache device does not cache the data resource corresponding to the resource information, and the experience of the user is improved.
In the method provided in the embodiment of the present invention, based on step S103, when detecting that the data resource corresponding to the resource information is cached, the pre-caching device pushes the data resource to the user. Fig. 3 shows a process of caching, by the pre-cache device, the data resource corresponding to the resource information, which specifically includes:
s301: acquiring a resource request record, wherein the resource request record comprises received historical resource requests;
in the embodiment of the present invention, a resource request record in the pre-caching device is obtained, where the resource request record includes each received historical resource request.
It should be noted that the historical resource requests in the resource request record may be all resource requests sent by the user within a preset period of time.
It should be noted that the pre-caching device has pushed the data resource corresponding to each historical resource request to the user.
S302: determining resource information corresponding to each historical resource request according to the resource request records, and acquiring resource types contained in the resource information corresponding to each historical resource request;
in the embodiment of the present invention, the pre-cache device determines each historical resource request according to the resource request record, obtains resource information corresponding to each historical resource request, and obtains a resource type included in the resource information corresponding to each historical resource request.
It should be noted that each resource information includes a resource type in addition to a corresponding resource name.
S303: sending each resource type to the CDN system, and triggering the CDN system to search resources according to each resource type;
in the embodiment of the invention, the front-end cache device sends the resource types corresponding to the acquired historical resource requests to the CDN system, and the CDN system searches resources according to the resource types.
S304: when receiving each data resource associated with each resource type fed back by the CDN system within a preset bandwidth idle time period, caching each data resource associated with each resource type.
In the embodiment of the present invention, the CDN system sends each data resource associated with each resource type that has been searched to the pre-caching device within a preset idle time period. After receiving the data resources associated with the resource types fed back by the CDN system, the pre-caching device caches the data resources associated with the resource types.
In the resource pushing method provided by the embodiment of the invention, the preposed cache device records the resource request each time after receiving the resource request each time. And acquiring each resource information corresponding to the historical resource request according to the resource request record, and acquiring the resource type contained in each resource information. And sending each resource type to the CDN system, searching resources by the CDN system according to each resource type, sending each searched data resource to the preposed cache device in a bandwidth idle time period, and caching each data resource sent by the CDN system by the preposed cache device. For example, when the historical resource request is a resource request of each video file, each video type corresponding to each video file is sent to the CDN system to perform resource search. If each video type comprises a travel comprehensive art and a gun battle type TV series, the CDN system searches video files corresponding to all the travel comprehensive art and the gun battle type TV series, sends the searched video files to the front-end cache device within the bandwidth idle time period, and the front-end cache device stores all the video files sent by the CDN.
The history resource request does not include the resource request in step S101. Before the above step S101, the data resources associated with the resource types corresponding to the historical resource requests are cached in the front-end caching device.
By applying the method provided by the embodiment of the invention, each resource type favored by the user is determined according to the historical request record, and each resource type is sent to the CDN system so as to obtain each data resource which is fed back by the CDN system after resource search and is associated with each resource type in a bandwidth idle time period, and each data resource is cached. If the user needs the cached data resource, the preposed cache system can directly push the data resource needed by the user to the user, thereby avoiding the overhigh bandwidth utilization rate in the bandwidth peak period and reducing the bandwidth cost.
In the method provided in the embodiment of the present invention, based on step S303, before the pre-caching device sends each resource type to the CDN system, the method may further include:
detecting the current bandwidth utilization rate between the preposed cache equipment and the CDN system in real time, and judging whether the current bandwidth utilization rate is lower than a preset bandwidth utilization threshold value or not;
and if the current bandwidth utilization rate is lower than a preset bandwidth utilization threshold value, sending each resource type to the CDN system, and triggering the CDN system to search according to each resource type.
In the resource pushing method provided in the embodiment of the present invention, after acquiring each resource type included in each resource information corresponding to a historical resource request, the pre-cache device may directly send each resource type to the CDN system, or specifically, may detect a bandwidth utilization rate between the pre-cache device and the CDN system in real time, and determine whether a current bandwidth utilization rate is lower than a preset bandwidth utilization threshold, and when the bandwidth utilization rate is lower than the preset bandwidth utilization threshold, prove that the current time period is not a peak time period, the pre-cache device may send each resource type to the CDN system, and trigger the CDN system to perform resource search according to each resource type.
It should be noted that, after the CDN system completes searching for the data resource associated with each resource type, each data resource associated with each resource type may be sent to the pre-cache device within the bandwidth idle time period, and the pre-cache device caches each data resource sent by the CDN system.
Optionally, after the CDN system searches for the data resource associated with each resource type, if the current bandwidth utilization is lower than the preset bandwidth utilization threshold, the CDN system may also send the data resource associated with each resource type to the pre-cache device in the current time period.
By applying the method provided by the embodiment of the invention, when the bandwidth utilization rate is lower than the bandwidth utilization threshold, each resource type is sent to the CDN system, so that the use of the bandwidth in the bandwidth peak time period is avoided, the bandwidth utilization rate in the bandwidth time period is reduced, and the bandwidth cost is reduced.
In the method provided in the embodiment of the present invention, the caching of the data resource by the pre-caching device specifically further includes:
receiving high-heat data resources pushed to the resource cache equipment by the CDN system according to the heat of the resources of the whole network within a preset bandwidth idle time period, and caching the high-heat data resources;
and when receiving a resource request sent by the user and corresponding to the high-heat data resource, pushing the high-heat data resource to the user.
In the method provided by the embodiment of the invention, the CDN system may analyze the resource heat of each data resource in the whole network, determine the resource request frequency corresponding to each data resource in the whole network, and determine that the data resource is a high-heat data resource when the resource request and frequency corresponding to any one data resource exceed the preset high-heat request frequency. And in a preset bandwidth idle time period, the CDN system can send the high-heat data resources to the front-end cache device, and the front-end cache device caches the high-heat data resources. When the front-end caching device receives a resource request which is sent by a user and corresponds to the high-heat data resource, the front-end caching device pushes the cached high-heat data resource to the user.
By applying the method provided by the embodiment of the invention, the preposed cache equipment can receive the high-heat resource sent by the CDN system in the bandwidth idle time period and cache the high-heat resource. When a user requests to acquire high-heat resources, the high-heat resources are directly pushed to the user by the front-end cache device, so that the current bandwidth utilization rate is reduced, and the bandwidth cost is reduced.
