Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a schematic structural diagram of a file downloading system according to an embodiment of the present invention. The file download system shown in fig. 1a comprises a server, a plurality of edge devices and a terminal. The server stores an object file to be downloaded by the terminal, and the object file can be a file in any format, such as a database logic file, a database physical file, a video file, a music file, and the like. The server is communicatively connected to a plurality of edge devices, including but not limited to intelligent routers, smart stereos, Network Attached Storage (NAS), webcams, and Storage-capable Network devices like guest clouds. The edge device is closer to the terminal than the server, and the target file segment can be stored in different edge devices for the terminal to download from the edge device.
Fig. 1b is a flowchart of a file downloading method according to an embodiment of the present invention, where the embodiment is applicable to a case where a server pushes segment data to an edge device and provides a downloading manner for a terminal. The method can be executed by a file downloading device, which can be formed by hardware and/or software and is generally integrated in a server, and specifically comprises the following operations:
and S110, pushing the plurality of sections of the target file to a plurality of edge devices.
In this embodiment, the server stores a plurality of files to be downloaded, obtains the heat of each file, and sequentially pushes the segment data of each file to the plurality of edge devices according to the sequence from high to low of the heat. For convenience of description and distinction, a file to be downloaded is taken as a target file, and the file push method provided by the embodiment is explained in detail.
Firstly, the server segments the target file into a plurality of segmented data according to a segmentation rule, wherein the segmentation rule comprises a size rule and a quantity rule of the segmented data. The size rules and the number of pieces of segmentation data may then be determined based on the size of the target document and the number of edge devices. For example, the larger the size of the target file, the larger the size of the segment data may be to ensure that the number of segments is unchanged. And the number of segments can be greater than or equal to the number of edge devices to fully utilize the storage space of each edge device.
Then, the plurality of pieces of segment data are pushed to the plurality of edge devices. Optionally, the same segmented data is pushed to more than two edge devices for backup storage.
And S120, receiving the information of the downloaded segmented data uploaded by each edge device.
Each edge device downloads at least one piece of segment data of the target file from the server and uploads information of the downloaded segment data to the server. The information of the segment data includes the number of the segment data, the hash value of the segment data, and the like. And the server receives the information of the downloaded segmented data uploaded by each edge device.
And S130, summarizing the information of the downloaded segment data uploaded by each edge device, and generating a segment data storage list.
Wherein the segment data storage manifest includes: the edge device information includes, but is not limited to, a Media Access Control (MAC) address of the edge device, a name and a version number of the edge device. For example, the edge device 1 uploads the information of the downloaded segment data 1-10, the edge device 2 uploads the information of the downloaded segment data 5-20, and the edge device 3 uploads the information of the downloaded segment data 21-100. The server aggregates the resulting segment data 1-4 to be stored in edge device 1, segment data 5-10 to be stored in edge device 1 and edge device 2, segment data 11-20 to be stored in edge device 2, and segment data 21-100 to be stored in edge device 3.
And S140, responding to a target file downloading request of the terminal, and sending the segment data storage list to the terminal so that the terminal can download the segment data from the edge equipment according to the segment data storage list and synthesize the segment data into the target file.
When a terminal needs to download a target file, a target file downloading request is sent to a server; and the server responds to the target file downloading request and sends the segment data storage list to the terminal. The terminal respectively sends a segment data downloading request to each edge device corresponding to each edge device information according to the segment data storage list; and receiving the fragment data returned by each edge device and synthesizing the fragment data into the target file.
Specifically, the terminal acquires, from the segment data storage list, the edge device information in which each segment data of the target file is stored, for example, segment data 1 to 4 are stored in the edge device 1, segment data 5 to 10 are stored in the edge device 1 and the edge device 2, segment data 11 to 20 are stored in the edge device 2, and segment data 21 to 100 are stored in the edge device 3. Then, a download request of the segment data 1 to 4 is sent to the edge device 1, a download request of the segment data 5 to 10 is sent to the edge device 1 or 2, a download request of the segment data 11 to 20 is sent to the edge device 2, and a download request of the segment data 21 to 100 is sent to the edge device 3.
Then, the edge device responds to the segment data downloading request of the terminal, and pushes the corresponding segment data to the terminal. And the terminal receives the segment data returned by each edge device and synthesizes the segment data into the target file.
Optionally, the terminal receives the segmented data returned by each edge device according to the network protocol supported by the edge device, and synthesizes the received segmented data into the target file according to the network protocol. Network protocols include, but are not limited to, Peer-to-Peer (P2P) protocols, hypertext Transfer Protocol (HTTP), and the like. Taking the P2P protocol as an example, the terminal is installed with a file downloading application program supporting the P2P protocol, the file downloading application program is started to download the segment data from the edge device, and the segment data are synthesized according to the sequence of the segment data.
In the embodiment of the invention, the server pushes a plurality of segmented data of the target file to a plurality of edge devices, and the segmented storage mode can improve the security of the file; the quantity of the pushed files is increased, so that the coverage rate of the files is increased by times; if the number of the edge devices is increased, the pushing speed can be multiplied; the server receives the information of the downloaded segment data uploaded by each edge device, summarizes the information of the downloaded segment data uploaded by each edge device, and generates a segment data storage list, so that the edge device information of each segment data of the target file stored in the edge device information is obtained, and the storage condition of the edge device is convenient to maintain; and when the terminal downloads the target file, the segment data storage list can be provided for the terminal so that the terminal can download the target file according to the list in a targeted manner, thereby saving network resources and improving the file downloading efficiency and the file downloading reliability.
At present, the cost of an edge device is lower than that of a Content Delivery Network (CDN), and in a scene in which a CDN Network storage manner is applied, the edge device may be used to shunt CDN nodes, so as to reduce CDN traffic and reduce Network cost. Based on this, in an optional embodiment, pushing a plurality of pieces of data of the target file to a plurality of edge devices includes: and pushing a plurality of sections of data of the target file to a plurality of edge devices in a bandwidth low peak period or a traffic cost low peak period.
Optionally, the bandwidth and the traffic cost of the network are counted at different time periods, and the time period of the bandwidth peak period and the traffic cost peak period is determined according to the bandwidth peak period and the traffic cost peak period, so that the plurality of segmented data of the target file are pushed to the plurality of edge devices.
In an optional implementation manner, the sending the segment data storage list to the terminal in response to a target file downloading request of the terminal includes: responding to a target file downloading request of a terminal, and judging whether the current moment is in a bandwidth peak period or a cost peak period; and if the current time is in the bandwidth peak period or the cost peak period, sending the segment data storage list to the terminal.
Optionally, the period of the bandwidth peak period or the cost peak period is determined according to the bandwidth and traffic cost of the network counted in different periods. And responding to the target file downloading request, judging whether the current moment is in a time period range of a bandwidth peak period or a cost peak period, and if so, sending the segment data storage list to the terminal. The terminal requests the segment data of the edge device immediately after receiving the segment data storage list. If not, the segmented data storage list can be sent to the terminal, or the target file is directly sent to the terminal through the CDN node.
In the two optional embodiments, the segmented data is pushed to the edge device in the bandwidth peak period or the cost peak period, and the segmented data is downloaded in the bandwidth peak period or the cost peak period, so that the data volume pushed to the CDN node is reduced, and the CDN cost and flow are reduced; meanwhile, network congestion is reduced, the pushing efficiency is improved, and the pushing cost is reduced.
Example two
The present embodiment is further optimized based on various optional implementation manners of the above embodiment. Optionally, the step of "pushing a plurality of pieces of segment data of the target file into a plurality of pieces of edge equipment" is refined to "sending the segment information of the plurality of pieces of segment data into the plurality of pieces of edge equipment, so that the edge equipment downloads and stores the corresponding piece of segment data according to the segment information; receiving actually received segmentation information fed back by the edge device, and determining unreceived segmentation information according to the actually received segmentation information; and sending the segmentation information which is not received to other edge devices so that the other edge devices can download and store the corresponding segmentation data according to the segmentation information, and improving the success rate and the efficiency of pushing the segmentation data by synchronizing the segmentation information and redistributing the segmentation information which is not received.
Fig. 2 is a flowchart of a file downloading method according to a second embodiment of the present invention. As shown in fig. 2, the method provided by the present embodiment includes the following operations:
s210, sending the segmentation information of the plurality of segment data to a plurality of edge devices, so that the edge devices can download and store the corresponding segment data according to the segmentation information.
The segmentation information includes, but is not limited to, an offset, size information, and identification of the segmented data. The identification is, for example, a number, hash value, etc. of the segmented data for uniquely identifying the segmented data.

After receiving the segmentation information, the edge device downloads and stores the corresponding segment data from the server according to the segmentation information. On the other hand, the actually received segment information is fed back to the server. This is because the originally delivered segment information is not successfully received by the edge device due to network failure or edge device failure. The edge device is required to feed back the segmentation information actually received. The server compares the actually received segmentation information with the originally issued segmentation information to determine the segmentation information which is not received.
And S230, sending the segmentation information which is not received to other edge devices, so that the other edge devices can download and store the corresponding segmentation data according to the segmentation information.
The other edge devices refer to devices other than the edge device to which the unreceived segment information is originally sent, among the plurality of edge devices. Optionally, a suitable edge device is determined according to the non-received segmentation information and current performance, current storage space and current bandwidth of other edge devices, for example, the current storage space is larger than the segmentation data corresponding to the non-received segmentation information, and the current performance is normal and the current bandwidth is larger than the bandwidth threshold.
And S240, receiving the information of the downloaded segment data uploaded by each edge device.
After downloading the segment data corresponding to the complete partial segment information or in the process of downloading the segment data, the edge device uploads the information of the downloaded segment data to the server.
And S250, summarizing the information of the downloaded segment data uploaded by each edge device, and generating a segment data storage list.
And S260, responding to a target file downloading request of the terminal, and sending the segment data storage list to the terminal so that the terminal can download the segment data from the edge equipment according to the segment data storage list and synthesize the segment data into the target file.
In this embodiment, by receiving actually received segment information fed back by the edge device, determining unreceived segment information according to the actually received segment information, and sending the unreceived segment information to other edge devices, synchronization of the segment information is achieved, and the unreceived segment information is redistributed, so that the success rate and efficiency of segment data pushing are improved, and further, the efficiency and reliability of file downloading are improved.
