Background
Because the resource file has a high heat after being released, a large number of user devices request a Content Delivery Network (CDN) server to download the resource file in a short time after being released. The access pressure of the CDN server is large, and the CDN server needs to push a file to be pushed to a large number of user devices at the same time.
In order to relieve the access pressure of the CDN server, in the related art, a resource file with a higher degree of popularity in the CDN server is pushed to a part of the terminals, and then a Peer-to-Peer (P2P) network is used, so that the terminal can obtain the resource file from the terminal that has pushed the resource file with the higher degree of popularity.

It should be noted that, in the embodiment of the present invention, the number of each device included in the file pushing system shown in fig. 1 is merely an example, and is not used to limit the number of each device in the embodiment of the present invention.
Referring to fig. 2, a file pushing method provided in an embodiment of the present invention may be applied to a file pushing system including a pushing server, an edge device, a node distribution server, and a terminal shown in fig. 1, where the method includes:
step 201, when detecting that there is a file to be pushed, the push server selects a target edge device from the edge devices connected to the push server, and pushes the file to be pushed to the target edge device.
Step 202, the target edge device acquires and stores the file to be pushed, which is pushed by the push server.

The obtaining request is used for requesting to obtain the identification of the file to be pushed.
And 204, the pushing server receives the acquisition request and sends the identifier of the file to be pushed to the terminal.
In step 205, the terminal receives the identifier of the file to be pushed, queries address information corresponding to the identifier of the file to be pushed from the node distribution server, and downloads the file to be pushed from the target edge device corresponding to the address information.
The embodiment of the invention at least comprises the following beneficial effects: the online state of the target edge device can be controlled, the target edge device can be stably in the online state, and other downloading tasks except for downloading the file pushed by the pushing server can not exist, so that the probability of interruption in the process of pushing the file to be pushed to the target edge device is low, and the file to be pushed can be pushed to a large number of target edge devices in a short time no matter in a peak time period or an off-peak time period. The embodiment of the invention can also push the file to be pushed in the target edge device to the terminal. Compared with the mode of downloading the file to be pushed from the CDN server by using the terminal in the prior art, the method and the device have the advantages that the number of the pushed files is more in the same time period, and the file pushing speed in the peak period is increased.
Referring to fig. 3, an embodiment of the present invention provides a file pushing method, which can be applied to the file pushing system shown in fig. 2, and is executed in a pushing server of the file pushing system, where the method includes the following steps:
step 301, when detecting that there is a file to be pushed, selecting a target edge device from the edge devices connected to the push server, and pushing the file to be pushed to the target edge device.
In one embodiment, the push server may select edge devices with a network health degree greater than a preset threshold value from among the edge devices with which the long connection is established, as target edge devices, and push a file to be pushed to the target edge devices.
Optionally, the download instruction may include an identifier of one or more files to be pushed. The downloading instruction may further include a storage location of the file to be pushed. For example, the storage location may be a Uniform Resource Locator (URL) of the file to be pushed.
Step 302, receiving an acquisition request sent by a terminal. The obtaining request is used for requesting to obtain the identification of the file to be pushed.
It can be understood that, when the terminal is in an online and idle state, the terminal may send an acquisition request to the push server. For example, the terminal may be a Personal Computer (PC), a smart television, or the like. When the terminal does not have the tasks of uploading or downloading other files except the file to be pushed, or the task quantity of uploading or downloading other files is smaller than the preset task quantity, the terminal can be considered to be in an idle state.
Step 303, sending the identifier of the file to be pushed to the terminal, so that the terminal receives the identifier of the file to be pushed, querying address information corresponding to the identifier of the file to be pushed from the node distribution server, and downloading the file to be pushed from the target edge device corresponding to the address information.
For example, the address information may be a URL of the file to be pushed in the edge device.
Optionally, the terminal may send an inquiry request to the node distribution server, where the inquiry request carries an identifier of the file to be pushed. And when receiving the query request, the node distribution server searches the address information corresponding to the identifier of the file to be pushed. When a plurality of address information corresponding to the identifier of the file to be pushed exists, the node allocation server may screen out, from the plurality of address information, address information corresponding to the edge device closest to the terminal, and send the screened address information to the terminal. After receiving the address information, the terminal may download the file to be pushed from the target edge device corresponding to the address information.
The embodiment of the invention at least comprises the following beneficial effects: the online state of the target edge device can be controlled, the target edge device can be stably in the online state, and other downloading tasks except for downloading the file pushed by the pushing server can not exist, so that the probability of interruption in the process of pushing the file to be pushed to the target edge device is low, and the file to be pushed can be pushed to a large number of target edge devices in a short time no matter in a peak time period or an off-peak time period. The embodiment of the invention can also push the file to be pushed in the target edge device to the terminal. Compared with the mode of downloading the file to be pushed from the CDN server by using the terminal in the prior art, the method and the device have the advantages that the number of the pushed files is more in the same time period, and the file pushing speed in the peak period is increased.
Optionally, referring to fig. 4, before the target edge device is selected in step 301, an embodiment of the present invention may further detect a file to be pushed, including the following steps:
step 401, detecting whether the specified file source includes file information.
The files corresponding to the file information comprise files with online duration less than preset duration and/or files with download amount within unit time greater than preset download amount. It should be noted that the file corresponding to the file information may also include other files, and the present invention is not limited in this respect.
For example, the file with the online time less than the preset time may be a newly online video, such as a new tv show, a new movie, and the like. The files with the download amount larger than the preset download amount in the unit time can be popular videos such as popular television dramas and popular movies.
Optionally, the file information includes an identifier of the file and a storage location of the file.
Step 402, when detecting that the designated file source includes file information, determining a file corresponding to the file information in the designated file source as a file to be pushed.
The embodiment of the invention also has the following beneficial effects: the push server in the embodiment of the invention can detect the file to be pushed from the specified file source, and the push server can detect the file to be pushed in the specified file source in time and push the file in time. Since the specified file source includes: the embodiment of the invention can also distribute the new drama in time, has higher push speed and improves the push efficiency of the new drama.
Optionally, the manner of selecting the target edge device in step 301 may further include: the method comprises the steps of obtaining attribute information of each edge device connected to a push server, and then selecting the edge device of which the attribute information meets preset conditions from the edge devices as a target edge device.
For example, the push server may establish a long connection with each edge device through a full duplex communication protocol (websocket), and each edge device may send its own attribute information to the push server at specified time intervals. Or, the push server may send an attribute information upload instruction to each edge device when detecting that the file to be pushed exists, and each edge device sends its own attribute information to the push server when receiving the attribute information upload instruction.
Optionally, the attribute information includes a network health level. The network health degree may include: network speed, network bandwidth utilization, etc.
In an embodiment, for each to-be-pushed area, a specified number of edge devices with a network health degree greater than a preset threshold may be selected as target edge devices from the edge devices with geographical locations located in the to-be-pushed area, where the specified number is a product of a total number of terminals in the to-be-pushed area and a preset ratio.
As can be understood, the total number of the terminals in the area to be pushed can reflect the reading requirement of the user in the area to be pushed on the file to be pushed, and the more the total number of the terminals is, the higher the reading requirement of the user in the area to be pushed on the file to be pushed is; the less the total number of the terminals is, the lower the reading requirement of the user on the file to be pushed in the area to be pushed is. For example, the preset ratio may be 1/2.
The embodiment of the invention also has the following beneficial effects: according to the embodiment of the invention, the edge device with the network health degree greater than the preset threshold can be selected as the target edge device, and the target edge device has higher network health degree relative to other edge devices, so that the downloading speed is higher, and the file pushing efficiency is improved.
Optionally, the manner of pushing the file to be pushed to the target edge device in step 301 includes: and sending a downloading instruction to the target edge device, wherein the downloading instruction comprises an identifier of the file to be pushed, so that the target edge device downloads the file to be pushed corresponding to the identifier from the CDN server.
The method for downloading the file to be pushed corresponding to the identifier from the CDN server includes: the target edge device sends a downloading request to the CDN server, wherein the downloading request comprises an identifier of a file to be pushed, so that after the CDN server receives the downloading request, the file to be pushed corresponding to the identifier is obtained and sent to the target edge device, and the target edge device receives and stores the file to be pushed sent by the CDN server.
Optionally, the download instruction may also be sent discretely to the target edge device.
For example: the target edge devices may be grouped into N groups and the download instructions sent to a group of target edge devices at intervals in the order of the groups. The time for each group of target edge devices to receive the downloading instruction is different, and the time for each group of target edge devices to request the CDN server to download the file to be pushed is also different.
The embodiment of the invention also has the following beneficial effects: if the downloading instruction is sent to each target edge device at the same time, the target edge device can be stably in an online state and does not include downloading tasks of other files except the file to be pushed, so that the target edge device can timely request the CDN server to download the file to be pushed after receiving the downloading instruction, the CDN server can receive a large number of downloading requests in a short time, and the access pressure of the CDN server is high.
The embodiment of the invention can discretely send the downloading instruction to the target edge device, so that the edge device has different time for receiving the downloading instruction and different time for requesting the CDN server to download the file to be pushed, thereby reducing the condition that the CDN server receives a large number of downloading requests in a short time, and reducing the access pressure of the CDN server.
Referring to fig. 5, a file pushing method provided in an embodiment of the present invention may be applied to the file pushing system shown in fig. 2, and is executed in an edge device of the file pushing system, where the method includes the following steps:
step 501, acquiring and storing a file to be pushed, pushed by a push server.
Step 502, when a download request sent by the terminal is received, searching for a file to be pushed corresponding to the identifier of the file to be pushed, and sending the file to be pushed to the terminal.
The downloading request comprises an identifier of the file to be pushed, and the downloading request is used for requesting to download the file to be pushed.
The embodiment of the invention at least comprises the following beneficial effects: the online state of the edge device can be controlled, the edge device can be stably in the online state, and other downloading tasks except for downloading the file pushed by the pushing server can not exist, so that the probability of interruption in the process of pushing the file to be pushed by the edge device is low, and the file to be pushed can be pushed to a large number of edge devices in a short time no matter in a peak time period or an off-peak time period. The embodiment of the invention can also push the file to be pushed in the target edge device to the terminal. Compared with the mode of downloading the file to be pushed from the CDN server by using the terminal in the prior art, the method and the device have the advantages that the number of the pushed files is more in the same time period, and the file pushing speed in the peak period is increased.
Optionally, the edge device in the embodiment of the present invention may further send attribute information of itself to the push server, where the attribute information includes: and sending the attribute information of the edge equipment to a push server at a specified time interval. Or when receiving an attribute information uploading instruction sent by the push server, sending the attribute information of the edge device to the push server.
Wherein the attribute information includes a network health level. Optionally, the attribute information may further include its own resource utilization rate (e.g., memory occupancy rate, Central Processing Unit (CPU) occupancy rate).
The embodiment of the invention also has the following beneficial effects: because the target edge device can send its own attribute information to the push server, the push server can select, from the edge devices, an edge device whose network health degree is greater than a preset threshold and whose resource utilization rate is less than an assigned threshold as the target edge device, so that the speed of downloading the file to be pushed from the CDN server by the selected target edge device is faster, and the push efficiency of the file to be pushed is higher.
Optionally, the manner of acquiring and storing the file to be pushed in step 501 includes: and receiving a downloading instruction sent by the push server, and then downloading and storing the file to be pushed corresponding to the identifier of the file to be pushed from the CDN server. And the downloading instruction comprises an identifier of the file to be pushed. The downloading instruction may further include a storage location of the file to be pushed.
Optionally, after the edge device obtains and stores the file to be pushed, the edge device may register the file stored in the edge device with the node distribution server, where the method includes: and sending a registration instruction to the node distribution server, wherein the registration instruction comprises the identification of the file to be pushed and the address information of the file to be pushed in the edge device. So that the node distribution server correspondingly stores the identifier of the file to be pushed and the address information.
The embodiment of the invention also has the following beneficial effects: the edge device can send the identifier of the file to be pushed and the address information of the file to be pushed in the edge device to the node distribution server, so that the identifier of the file to be pushed and the address information of the file to be pushed in the edge device are correspondingly stored in the node distribution server. Therefore, after receiving the identifier of the file to be pushed sent by the push server, the terminal can search the address information corresponding to the identifier from the node distribution server, and obtain the file to be pushed from the edge device corresponding to the address information. Compared with the mode that the terminal acquires the file to be pushed from the CDN server, the terminal in the embodiment of the invention can acquire the file to be pushed from the edge device without acquiring the file to be pushed from the CDN server, thereby reducing the access pressure and bandwidth cost of the CDN server.
In addition, after the file to be pushed is pushed, the device which needs to acquire the file to be pushed can acquire the file from the edge device or the terminal by using a Peer-to-Peer (P2P) network, so that the situation that the device which needs to acquire the file to be pushed acquires the file to be pushed from the CDN server is reduced, the P2P traffic is improved, and the access pressure of the CDN server is reduced.
In order to more clearly explain the file pushing method provided by the embodiment of the present invention, referring to fig. 6, the file pushing method provided by the embodiment of the present invention includes the following steps:
step 601, the push server establishes long connection with each edge device.
Step 602, each edge device sends attribute information of the edge device to the push server at specified intervals. Wherein the attribute information includes a network health level of the edge device.
Step 603, when the push server detects that the file to be pushed exists, according to the network health degree and the geographical position of each edge device connected to the push server, for each area to be pushed, selecting a specified number of edge devices with the network health degree greater than a preset threshold value from the edge devices with the geographical positions located in the area to be pushed as target edge devices.
In step 604, the push server sends a download instruction to the target edge device.
Step 605, the target edge device responds to the downloading instruction, and downloads the file to be pushed from the CDN server.
Step 606, the target edge device sends the identifier of the file to be pushed and the address information of the file to be pushed in the target edge device to the node distribution server.
In one embodiment, the edge device may send its Internet Protocol (IP) address, a geographic location, an identifier of the file to be pushed, and a URL address of the file to be pushed to the node distribution server.
Step 607, the node distribution server receives and correspondingly stores the identifier of the file to be pushed sent by the target edge device and the address information of the file to be pushed in the target edge device.
Optionally, the node distribution server may further receive and correspondingly store the IP, the geographic location, the identifier of the file to be pushed, and the URL of the file to be pushed, which are sent by the target edge device.
In step 608, the push server receives the acquisition request sent by the terminal, and sends the identifier of the file to be pushed to the terminal in response to the acquisition request.
Step 609, the terminal receives the identifier of the file to be pushed, and requests the address information corresponding to the identifier of the file to be pushed from the node distribution server.
Step 610, the terminal receives the address information of the file to be pushed sent by the node distribution server, and downloads the file to be pushed from the edge device corresponding to the address information.
Compared with the mode that the push server indicates the terminal to download the file to be pushed from the CDN server, the embodiment of the invention also has the following beneficial effects:
1. in this way, the terminal can only download the file to be pushed from the CDN server, so that the CDN server bandwidth requirement and bandwidth cost are high. In the embodiment of the invention, the file to be pushed in the CDN server can be pushed to the target edge device first, and the terminal can obtain the file to be pushed from the target edge device when needing to obtain the file to be pushed, so that the access pressure on the CDN server when a new drama is pushed is reduced, and the bandwidth requirement and the bandwidth cost of the CDN server are reduced.
2. Because the push server passively pushes the file to be pushed to the terminal (that is, the push server sends the identifier of the file to be pushed to the terminal when receiving the acquisition request sent by the terminal, so that the terminal acquires the file to be pushed according to the identifier), and the number of terminals requesting to push the file to be pushed in each area to be pushed is different, there may be a large number of terminals requesting to push the file to be pushed in some areas to be pushed, and the access demand of users in the areas to be pushed for the file to be pushed is small, which causes the waste of storage resources. There may also be some areas to be pushed that require fewer terminals to be pushed for files to be pushed, and users in the area have a large access demand for files to be pushed, so that the pushed number of files to be pushed is not enough to meet the access demand for files to be pushed, and the user equipment still needs to obtain the files from the CDN server when accessing the files to be pushed. The embodiment of the invention can push the file to be pushed to the target edge device, and the target edge device can be passively distributed with the file to be pushed, so that the quantity of the file to be pushed in each area to be pushed is controllable. The access pressure of the CDN server can be reduced on the basis of saving resources.
3. Due to the fact that the online state of the terminal is not controllable, the user equipment needing to acquire the file to be pushed cannot acquire the file to be pushed from the offline terminal. The embodiment of the invention can push the file to be pushed to the target edge device, the online state of the target edge device is controllable, the target edge device can be stably in the online state and has larger storage space, and the user equipment needing to acquire the file to be pushed can acquire the file to be pushed from the target edge device at any time.
