Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In order to improve P2P sharing efficiency of media resources, an embodiment of the present application provides a resource obtaining method based on a PCDN, referring to fig. 2, the method is applied to an initial resource node, where the initial resource node may be any resource node sender in the PCDN, and the method may include:
step S100: resource service data is determined based on the historical resource acquisition requests.
The historical resource acquisition request may be each resource request from the client peer received by the initial resource node in a historical manner, the initial resource node may count and record the resource requests, and determine resource service data according to the historical resource acquisition request, where the resource service data refers to data related to the service capability of the initial resource node occupied by each resource stored in the initial resource node.
It should be noted that, the method for requesting resources by the client peer may specifically be that the client peer obtains the resource list to be obtained from the resource connection server tracker, and then requests corresponding data from the resource node peer, and the method for requesting resources by the client peer may refer to the prior art, which is not described herein in detail.
In an alternative implementation, step S100 may include the steps of:
step S101: and determining the target resource and the identification information of the target resource according to the historical resource acquisition request.
The history resource obtaining request includes a target resource of the history request and identification information of the target resource, and it should be noted that the identification information of the target resource is used for uniquely identifying the target resource, and the identification information may be determined according to an MD5 value of an information abstraction algorithm of a resource storage path.
Step S102: obtaining service resource usage data corresponding to a target resource in a preset period, wherein the service resource usage data comprises: resource access amount duty ratio data and resource bandwidth occupation data.
After the initial resource node responds to the historical resource obtaining request, relevant information of the target resource corresponding to the request, such as identification information of the target resource, file size information of the target resource, transmission rate condition of the target resource and the like, is recorded correspondingly. The initial resource node may acquire service resource usage conditions corresponding to the target resource in the preset period, including, for example, resource access amount occupation ratio data and resource bandwidth occupation data. It should be noted that the preset period is set by a technician as required, and as an option, the preset period may be set to 30 seconds.
It can be understood that the resource access amount duty ratio data refers to data of all resource access amounts of the initial resource node with the target resource access amount, the resource bandwidth occupied data refers to data of total transmission loans of the initial resource node with the target resource access amount, and the service resource use condition is recorded by the initial resource node according to the related information.
Step S103: and associating the identification information of the target resource with service resource use data corresponding to the target resource to obtain resource service data.
Specifically, the corresponding service resource use data are associated according to the identification information of the resources, so that each resource corresponds to the corresponding service resource use data one by one, and the hot spot resources are convenient to determine according to the service resource use data.
Step S200: and determining the hot spot resources according to the resource service data in response to the bandwidth utilization of the initial resource node exceeding a preset threshold.
In the embodiment of the application, when the bandwidth utilization rate of the initial resource node exceeds a preset threshold, the hot spot resource is determined according to the resource service data. It will be appreciated that when the bandwidth usage of a resource node exceeds a preset threshold, it is stated that certain resource data in that resource node is densely requested by clients at the current time node.
In an alternative implementation, step S200 may include: determining the hot spot resources according to the resource service data and preset hot spot conditions in response to the bandwidth utilization rate of the initial resource node exceeding a preset threshold; the preset hot spot conditions comprise: the resource access amount occupied data is larger than a preset occupied threshold value, and the resource bandwidth occupied data is larger than a preset occupied threshold value.
Specifically, in the embodiment of the present application, whether a resource is a hot spot resource is determined by the resource service data and the preset hot spot condition, specifically, whether the resource access amount occupation data corresponding to the resource is greater than the preset occupation threshold value and whether the resource bandwidth occupation data is greater than the preset occupation threshold value are determined, if both the two are the same, the resource may be determined to be the hot spot resource.
It may be understood that, in the embodiment of the present application, the resource service data is counted according to a preset period (for example, 30 seconds), and accordingly, the judgment of the hotspot resource may be synchronous with the preset period, or may be set as required, and the time span should be greater than the preset period, for example, one minute, two minutes, or the like.
In an alternative implementation, the resource data in the resource node server in the embodiment of the present application may be stored in the form of a multi-level directory file.
Specifically, one target resource corresponds to one streaming media resource, and one streaming media resource can include streaming media sub-resources with various code rates and various resolutions, for example: the same video resource comprises streaming media sub-resources with multiple code rates and multiple resolutions, each streaming media sub-resource in one streaming media resource can be segmented by using a protocol of a slice file and a slice directory file, such as HLS (HTTP Live Streaming) or DASH (Dynamic Adaptive Streaming over HTTP), and the streaming media sub-resources are stored in the directory file in a multi-layer directory file mode, so that each streaming media sub-resource included in one streaming media resource is issued as a whole, a client peer requests a corresponding slice file from the directory file when requesting the resource, and therefore, as the multimedia heat is related to content, all the media with the code rates share one heat calculation, so that the heat information of the resource is counted according to one streaming media resource, and the follow-up transverse expansion is convenient. And in addition, unlike the mode that the common P2P uses the data block as a sharing unit, the sharing among peers is performed by using the slice file as a unit, so that the blocking checking overhead is reduced, and the data acquisition efficiency is improved.
It can be understood that, since each streaming media sub-resource included in one streaming media resource is issued as a whole and stored in the form of a multi-level directory file, the granularity of subsequent judgment on the hot spot file can be set by a technician, which is specifically as follows.
The method comprises the following steps: the method comprises the steps of uniformly judging each streaming media sub-resource in one streaming media resource, namely uniformly judging the heat of resources with different code rates and different resolutions in one video resource, and subsequently transversely expanding the whole video resource, for example: the video A comprises sub-videos with four resolutions, the four sub-videos are regarded as a total resource to carry out heat judgment, and after the video A is judged to be a hot spot resource, the video A comprising the four sub-videos is transversely expanded. The second mode is as follows: and (3) carrying out independent heat judgment on the streaming media sub-resources with each code rate and each resolution, and subsequently carrying out transverse expansion on the streaming media sub-resources which are determined to be hot spot resources. For example: the video A comprises sub-videos with four resolutions, wherein the four resolutions are respectively: and performing heat calculation on the four sub-videos corresponding to the four resolutions independently, and performing transverse expansion on the sub-video of the first resolution if the sub-video of the first resolution is determined to be a hot spot resource. In the embodiment of the application, the resource is stored in a multi-level directory file mode, so that the judgment granularity of the hot spot files can be adjusted and set according to the needs, and the determination modes of the two hot spot resources can be selected according to the actual conditions of bandwidth capacity, storage space, resource size and the like of the resource nodes.
In practical application, the storage example of the HLS slice file used by the streaming media sub-resource in the form of a multi-level directory file is as follows, the HLS slice uses an index file in m3u8 format, multi-level index can be used in multi-parameter, and the lower level index file comprises a plurality of secondary index files of audio and video parameters, and the code is as follows:
#EXTM3U
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="aac",NAME="English", \
default=yes, auto=yes, language= "en", secondary index description
Uri= "main/englist-audio.m3u8" \secondary index address
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="aac",NAME="Deutsch", \
Default=no, autoselect=yes, language= "de", \secondary index description
Uri= "main/german-audio.m3u8" \secondary index address
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="aac",NAME="Commentary", \
Default=no, autoselect=no, language= "en", secondary index description
Uri= "comment/audio-only.m3u8" \secondary index address
In practical application, storage examples of streaming media sub-resources in the form of multi-level directory files are as follows, and DASH slices use XML files in mpd format, and files use hierarchical structures to store different contents, and the codes are as follows:

Step S300: and sending the identification information of the hot spot resource to a resource node manager, so that the resource node manager forwards the identification information of the hot spot resource to a newly-added resource node, and the newly-added resource node acquires the hot spot resource according to the identification information of the hot spot resource.
Specifically, the initial resource node sends the identification information of the hot spot resource determined to the resource node manager, the resource node manager is used for managing, for example expanding capacity, cleaning and the like, the resource node manager sends the identification information of the hot spot resource to the newly-added resource node after receiving the identification information of the hot spot resource, and the newly-added resource node can obtain the hot spot resource based on the identification information of the hot spot resource, so that the transverse expansion of the hot spot resource is realized. It should be noted that, the identification information of the hot spot resource is determined according to the MD5 value of the resource storage path of the hot spot resource, and the identification information of the hot spot resource is used to uniquely identify the hot spot resource.
In a specific implementation manner, the obtaining, by the newly added resource node, the hot spot resource according to the identification information of the hot spot resource includes: the newly added resource node sends the identification information of the hot spot resource to the resource connection server, and the resource connection server feeds back the initial resource node address with the hot spot resource to the newly added resource node based on the identification information of the hot spot resource, and the newly added resource node downloads the hot spot resource according to the identification information of the hot spot resource and the initial resource node address.
In an alternative implementation manner, the newly added resource node in the embodiment of the present application is determined by the resource node manager from the candidate resource node library according to the historical service quality or the resource service requirement, where the resource service requirement includes the service requirement of the operator and the service resource regional requirement.
Specifically, the candidate resource node library includes a plurality of standby resource nodes, and the resource nodes may be used resource nodes, i.e. resource nodes which have provided the resource acquisition service, or resource nodes which are newly added into the PCDN, i.e. resource nodes which have not provided the resource acquisition service. The resource node manager may consider and select when determining the newly added resource node based on historical service quality (including bandwidth capability, storage space, etc. as provided by history) or resource service requirements (including service requirements of an operator and regional requirements of service resources) of the standby resource node. The operator service demand is selected based on statistics of the client's network service provider ISP, such as mobile, corporate, or telecommunications, and the service resource regional demand is selected based on statistics of the client's regional distribution, such as south-China, middle-China, or north-China.
In an optional implementation manner, in the embodiment of the present application, when the resource service data of the hot spot resource in the hot spot resource no longer meets the preset hot spot condition in the preset time period, the newly added resource node cleans the hot spot resource.
It can be understood that the hot spot resource is time-efficient, and when the heat of the hot spot resource is lower than the threshold value, capacity expansion cleaning work is performed, so that the system is more flexible.

It should be noted that, the number of the initial resource nodes, the newly added resource nodes, the clients, the resource connection servers and the resource node manager is not limited in the present application.
