The following first describes a video processing method provided in an embodiment of the present invention from the perspective of a distributed storage system.

The video processing method provided by the embodiment of the invention is applied to a distributed storage system, wherein the distributed storage system comprises a push server and edge equipment. Fig. 1 is a flowchart of a video processing method according to an embodiment of the present invention. Referring to fig. 1, the video processing method may include the steps of:

s10: the method comprises the steps that when a downloading task does not exist, the edge device sends an information pushing request to a pushing server; the information push request carries equipment information of the edge equipment;

s20: the push server searches storage position information of a target video to be pushed to the edge device based on the device information;

s30: the push server sends a push message carrying the storage position information to the edge device;

s40: and the edge device responds to the push message, downloads the target video according to the storage position information and stores the target video.

In this way, the edge device can download and store the target video, so that the target video can be stored by the edge server and the edge device outside the central server, and the storage pressure of the edge server for storing the target video is shared. In addition, by applying the video processing mode, a large number of edge server devices are not required to be added to store the video, so that the cost for deploying the edge server is reduced. Moreover, when the user equipment sends a video access request aiming at the target video, the target video can be downloaded from the edge equipment without downloading the target video from the server side, so that the data transmission distance is shortened, and the speed of acquiring the target video is improved. In addition, the idle bandwidth resources of the user side can be fully utilized, the use of the bandwidth resources of the server side is reduced, and the bandwidth cost of the server side is reduced.

Fig. 2 is a flowchart of another video processing method according to an embodiment of the present invention. Referring to fig. 2, the video processing method applied to the distributed storage system may include:

the edge device is a near-user side device and can be continuously and always in a power-on state. For example, the edge device may be a router or a NAS (Network Attached Storage) device, but is not limited thereto.

It is understood that a router is a gateway device dedicated to connecting multiple logically separate networks, and a NAS device is a device with data storage capabilities connected to a network.

In addition, it is understood that the edge device may send an information push request to the push server when detecting that there is no download task of the edge device itself, or when detecting that the processor resources of the edge device are sufficient. In addition, it is also reasonable that the ue sends an information push request to the push server every preset time interval. Wherein the predetermined period of time includes, but is not limited to, 2 minutes.

Since the information push request carries the device information of the edge device, the edge device may report the device information of the edge device to the push server. The device information of the ue may include the geographical location information of the edge device, and may also include the storage capacity and the remaining storage capacity of the edge device, and preset file size information corresponding to the download rate of the edge device, which is not limited to this. For example, the geographical location information may be: and A is omitted.

S21: the push server searches storage position information which has a mapping relation with the geographic position information of the edge equipment from the stored push table to be used as target storage position information; wherein, the push table records: mapping relation of geographic position information, storage position information of the video to be pushed and file size information of the video to be pushed;

s22: the push server searches file size information which has a mapping relation with the target storage position information from the push table;

s23: the push server takes the target storage position information corresponding to the target file size information in the file size information as the storage position information of the target video to be pushed to the edge device; the size information of the target file is less than or equal to the storage capacity of the edge device;

for example, the push table records: the mapping relation of the storage position information of videos a1, a2, a3 and the like to be pushed and the file size information of videos a1, a2, a3 and the like to be pushed in province A; b province, storage location information of videos to be pushed B1, B2, B3 and the like, and file size information of videos to be pushed B1, B2, B3 and the like, and the like.

Assuming that the geographical location information of the edge device is a province, the push server may find, in the push table, storage location information of videos to be pushed, such as a1, a2, and a3, which have a mapping relationship with the a province, and use the found storage location information as target storage location information. Then, the push server may find in the push table: and the file size information of the videos to be pushed, such as a1, a2 and a3, which have a mapping relation with the target storage position information. Then, the push server may use the target storage location information corresponding to the target file size information in the file size information as the storage location information to be pushed to the edge device.

In one implementation, the size information of the target file is: file size information less than or equal to the storage capacity of the edge device. In this way, the push server may determine the storage location information of the target video to be pushed to the edge device according to the geographical area where the edge device is located and the storage capacity of the edge device.

In another implementation manner, the target file size information is: and the file size information is less than or equal to the residual storage capacity of the edge device and less than or equal to the file size information of the preset file size information corresponding to the downloading rate of the edge device. In this way, the push server may determine the storage location information of the target video to be pushed to the edge device according to the geographic area where the edge device is located, the remaining storage capacity, and the preset file size information corresponding to the download rate of the edge device.

Of course, the push server may also arbitrarily select one or more videos to be pushed as target videos to be pushed to the edge device. Then, it is also reasonable to use the target storage location information of the target video as the storage location information of the target video to be pushed to the edge device.

After obtaining the storage location information of the target video to be pushed to the edge device, the push server may send a push message carrying the storage location information to the edge device. Further, the edge device may download the target video according to the storage location information and store the target video in response to the push message.

Specifically, the edge device may detect whether a processor resource of the edge device is greater than a preset threshold. When detecting that the processor resource of the edge device is greater than the preset threshold, the edge device may download the target video according to the storage location information and store the target video. Thus, the edge device can smoothly process the service to be processed by the edge device.

For the edge device, since there is no process other than implementing its function to read the storage space of the edge device. Thus, when software is deployed on the edge device to implement the video caching function, the storage space can be made fully controllable without concern for affecting the use of other processes. And, since the edge device is a stable online device that can be continuously and always on, the edge device can provide stable downloads at various periods of time after storing video with the edge device.

In addition, because the number of edge devices such as a router or an NAS device is very large, when the edge devices are used for storing videos, the storage pressure and the access pressure of the existing edge server can be relieved, and a large number of edge server devices are not required to be added for storing videos, so that the cost for deploying the edge server is reduced.

In addition, because the distance between the edge device and the user device is short, when the user device and the edge device perform data interaction, the transmission channel distance of the data interaction is short. Therefore, the network delay is smaller, and the data interaction speed is improved. And, idle bandwidth resources near the user side can be utilized, thereby reducing bandwidth costs.

Wherein the user equipment includes but is not limited to: desktop computers, notebook computers, smart televisions, and smart phones.

The distributed storage system may include a scheduling server in addition to the push server and the edge device.

Fig. 3 is a flowchart of another video processing method according to an embodiment of the present invention. Referring to fig. 3, the video processing method applied to the distributed storage system may include the steps of:

s51: before the push server executes step S21, the scheduling server counts the number of access requests of the user equipment to each video within a preset time period;

the scheduling server may count the number of times of access requests of the user equipment to each video in a preset time period. Wherein the preset time period may be 00: the time period of 00 to 24:00 is, of course, not limited thereto. For example, the scheduling server may schedule 24: and the number of requested accesses of the video A is counted to 10000 at the time of 00.

It is understood that it is also reasonable that the scheduling server may count the number of requested accesses to each video requested to be accessed by the user equipment within a preset time period and located in a preset geographical area.

S52: the scheduling server takes the videos with the access request times larger than the preset access times as videos to be pushed;

the video with the larger access amount can be used as the video to be pushed, because the video with the larger access amount generally has a higher access rate in a future period of time.

For example, the number of requested accesses of the target video in 7 months and 1 day is 10000, the preset number of accesses is 5000, and it is seen that the number of requested accesses is greater than the preset number of accesses, which indicates that the target video has a higher access rate, i.e., a higher heat. And, in a normal case, the target video will have a higher access rate in 7 months and 2 days. That is, the target video is likely to be requested to be accessed by the user on day 7, month 2. Therefore, in order that the user equipment can quickly access the target video subsequently, the scheduling server can take the target video as the video to be pushed.

S53: the scheduling server sends the storage position information, the file size information and the geographical position information corresponding to the storage position information of the video to be pushed to the pushing server;

s54: and the push server constructs a push table by using the storage position information, the file size information and the geographical position information corresponding to the storage position information of the video to be pushed.

After determining the video to be pushed, the scheduling server may send the storage location information, the file size information, and the geographic location information corresponding to the storage location information of the video to be pushed to the pushing server. In turn, the push server may build a push table based on the content sent by the scheduling server. Thereby, the push server can subsequently push to the edge device based on the push table: and the push message carries the storage position information of the video to be pushed.

It is understood that the above steps S51 to S54 may be executed before step S10, or may be executed after step S10, which is all reasonable.

Wherein, in the step S30: before the push server sends the push message carrying the storage location information to the edge device, the following operations may also be included:

the scheduling server sends the number of times of access requests of the user equipment to the video to be pushed to the pushing server within a preset time period;

the method comprises the steps that a push server searches for a preset number of push copies corresponding to the number of access requests of videos to be pushed aiming at the videos to be pushed corresponding to each piece of geographic position information; obtaining the number of the to-be-pushed videos in a geographic area corresponding to the geographic position information by multiplying the preset number of the to-be-pushed videos by a weighting coefficient corresponding to the geographic position information;

the method comprises the steps that a pushing server judges whether the number of pushed copies of target pushing messages which are historically pushed to edge equipment in a geographic area is smaller than the number of copies to be pushed; the target push message carries storage position information of the target video;

and if the pushed number of copies is smaller than the number of copies to be pushed, the pushing server triggers the operation of sending the pushing message carrying the storage position information to the edge equipment, and adds one to the pushed number of copies.

For example, the push server may search, for a video K to be pushed corresponding to the northwest region, a preset number of pushed copies 1000 corresponding to a number of requested accesses 10000 of the video K to be pushed. Since the network quality in the northwest area is poor, in order to ensure that the user can quickly access the video K to be pushed, the push server may multiply the preset number of pushed copies 1000 by the weighting coefficient 2 corresponding to the northwest area, so as to obtain the number of pushed copies 2000 of the video K to be pushed in the geographic area corresponding to the northwest area.

Moreover, the push server may further determine whether the number of pushed copies of the target push message historically pushed to the edge device in the northwest area is less than 2000 to-be-pushed copies. The target push message carries storage position information of the video K to be pushed. If the pushed number of copies is less than 2000, it indicates that the pushed number of copies cannot meet the access requirement, and at this time, the push server may trigger step S30 and add one to the pushed number of copies. If the number of pushed copies is equal to the number of to-be-pushed copies, it indicates that the number of pushed copies can satisfy the access requirement, and the push server may abort triggering step S30.

Therefore, the number of the to-be-pushed videos to be pushed to the geographic area can be determined based on the number of access requests of the to-be-pushed videos and the geographic position information of the geographic area to which the to-be-pushed videos are to be pushed, so that the pushing message carrying the storage position information of the to-be-pushed videos can be sent to the geographic area, and the to-be-pushed videos of the number of the to-be-pushed videos can be stored in the geographic area.

And in order that the user equipment can access the target video from the edge equipment more quickly when the edge equipment is used as an access source of the target video, the edge equipment can also send registration information to the scheduling server after downloading the target video according to the storage position information and storing the target video. Wherein the registration information is used to: indicating that the edge device has downloaded and stored the target video.

Thus, the scheduling server may store the registration information after receiving the registration information. In this way, the scheduling server can determine the edge device storing the target video based on the registration information when receiving the video access request of the user device for the target video. Further, the scheduling server may send the storage address information of the edge device to the user device, so that the user device accesses the target video based on the storage address information.

In addition, it is understood that the scheduling server may also send the stored registration information to the push server after storing the registration information. In this way, before sending the push message carrying the storage location information to the edge device, the push server may first detect whether the edge device stores the target video according to the received registration information. If the target video is not stored in the edge device, the push server may trigger an operation of sending a push message carrying the storage location information to the edge device. If the target video is stored in the edge device, the push server may give up triggering an operation of sending a push message carrying storage location information to the edge device. In this way, pushing duplicate target videos to the edge device may be prevented.

In summary, by applying the video processing method provided by the embodiment of the present invention, the edge device may download and store the target video, so that the target video may be stored by the edge server and the edge device other than the central server, and the storage pressure of the edge server for storing the target video is shared. In addition, by applying the video processing mode, a large number of edge server devices are not required to be added to store the video, so that the cost for deploying the edge server is reduced. Moreover, when the user equipment sends a video access request aiming at the target video, the target video can be downloaded from the edge equipment without downloading the target video from the server side, so that the data transmission distance is shortened, and the speed of acquiring the target video is improved. In addition, idle bandwidth resources of the user side can be fully utilized, the use of the bandwidth resources of the server side is reduced, and the bandwidth cost of the server side is reduced.

The following describes a video processing method provided by an embodiment of the present invention from the perspective of a push server.

Fig. 4 is a flowchart illustrating a video processing method according to an embodiment of the present invention. Referring to fig. 4, the method may include:

s401: receiving an information push request sent by edge equipment; the information push request carries equipment information of the edge equipment;

s402: searching storage position information of a target video to be pushed to the edge device based on the device information;

s403: sending the push message carrying the storage position information to the edge device; wherein the push message is used to: and indicating the edge device to download the target video according to the storage position information and store the target video.

In the embodiment of the present invention, the push server may receive an information push request sent by the edge device. The information push request carries device information of the edge device. Then, based on the device information, the storage location information of the target video to be pushed to the edge device can be searched. The push message carrying the storage location information may then be sent to the edge device. Wherein the push message is used for: and instructing the edge device to download the target video according to the storage position information and store the target video.

In this way, the target video can be stored by the edge server and the edge device outside the central server, and the storage pressure of the edge server for storing the target video is shared. In addition, because a large number of edge server devices are not required to be added for storing the video, the cost for deploying the edge server can be reduced. Moreover, when the user equipment sends a video access request aiming at the target video, the target video can be downloaded from the edge equipment without downloading the target video from the server side, so that the data transmission distance is shortened, and the speed of acquiring the target video is improved. In addition, the idle bandwidth resources of the user side can be fully utilized, the use of the bandwidth resources of the server side is reduced, and the bandwidth cost of the server side is reduced.
