File transmission method and device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for file transmission.
Background
With the rapid development of internet technology, the data volume of network information is also becoming larger, and the requirement of enterprises for storing mass data is becoming more important. The conventional file storage system has the problems of limited disk space, insufficient processing capacity and the like, and cannot meet the high-capacity storage requirement of users.
One existing solution is to upload files to be stored by a user to a plurality of node servers in a distributed storage manner, so as to meet the high-capacity storage requirement of the user. For example, if a distributed method is adopted, 500GB of files can be stored in the node server a, and another 500GB of files can be stored in the node server B. However, since the files are distributed in different node servers, when the user manages the files, it is necessary to manage part of the files stored in the node server a and the files stored in the node server B at the same time, so that the requirement of centralized management of the user cannot be satisfied.
Another solution is to use a centralized cloud storage service to centrally upload the files to be stored by the user into the cloud storage device. However, although this method can meet the requirement of the user for centralized management of the files, because the uploading rate that can be provided by the cloud storage device is limited, the method cannot meet the requirement of the user for uploading the files rapidly and concurrently when the data volume of the files is excessive.
Based on this, a file transmission method is needed at present, which is used for solving the problem that in the prior art, quick uploading and centralized management cannot be considered in the file transmission process.

It should be noted that the client device in the present application may be various types of devices, for example, a notebook computer, a smart phone, a tablet computer, a smart television, and the like, which is not limited in particular.
Embodiment one:
based on the system architecture shown in fig. 1, fig. 2 schematically shows a flow diagram corresponding to a file transmission method according to an embodiment of the present invention, which specifically includes the following steps:
step 201, a node server receives an uploading file sent by any client device in a client cluster; the uploading files are files in an uploading file set sent by the client cluster, and all the files in the uploading file set correspond to the same data body.
Step 202, the node server generates meta information of the uploading file, wherein the meta information comprises a data main body to which the uploading file belongs.
And 203, the node server sends the uploaded file and the meta information to the cloud storage device.
In step 204, the cloud storage device receives the upload file sent by the node server and meta information of the upload file.
In step 205, the cloud storage device determines a target storage area of the uploaded file according to the meta information and a preset correspondence between the data entity and the storage area.
In step 206, the cloud storage device stores the uploaded file and the meta information in the target storage area.
It should be noted that, the steps 201 to 203 may be performed by any node server in the node server cluster 102 shown in fig. 1, for example, may be performed by the node server 1021 shown in fig. 1; the above steps 204 to 206 may be performed by the cloud storage apparatus 101 shown in fig. 1.
Therefore, aiming at the service with large data volume and transmission delay requirement, on one hand, a plurality of client devices in the client cluster can simultaneously send the uploading file set of the same data body to the node server cluster, and a plurality of node servers in the node server cluster provide available bandwidths to receive the uploading file set sent by the client cluster, so that the purpose of rapid file transmission can be realized, and the file transmission rate is improved; on the other hand, in order to ensure convenience in post management of the data of the service, after each node server receives the uploading file sent by the client device, the uploading file of the same data main body can be synchronously stored in the cloud storage device. According to the analysis, the data uploading service meeting the transmission delay requirement can be provided for the same data body, and the requirement of centralized storage can be met.
Specifically, before step 201 is performed, the communication relationship between the client and the node server includes various types, for example, the node server may receive an upload file sent by any client device in the client cluster, and in one example, the node server may receive an upload file sent by the client device 1031 shown in fig. 1, may receive an upload file sent by the client device 1032, and may also receive an upload file sent by the client device 1033.
In another example, the node server may also receive the upload files transmitted by the client devices designated in the client device 1031, the client device 1032, and the client device 1033 shown in fig. 1. For example, the client device may send the upload file to the designated node server according to its own location information. For example, as shown in fig. 3, a flowchart of a method for determining, by a client device, a node server corresponding to an upload file according to an embodiment of the present invention is provided, where the method may be performed by the client device 1031 shown in fig. 1, and includes the following steps:
in step 301, a client device sends an upload request to a DNS server, the upload request including location information of the client device.
The location information of the client device may refer to an IP address of the client device, or may refer to a geographic location of the client device. As shown in table 1, is one example of location information of a client device. As can be seen from the contents shown in table 1, each client device has a corresponding geographical location, and taking the client device 1 shown in table 1 as an example, the IP address corresponding to the client device 1 is: 222.64.232.189, the corresponding geographic locations are: the location information of other client devices in the Shanghai Mincing area may be referred to in particular by means of a table, which will not be described in detail here.
Table 1: one example of location information for a client device
Changes in client devices IP address Geographic location
Client device 1 222.64.232.189 Shanghai Min Shengzhan
Client device 2 220.155.1.196 Haidian District, Beijing
Client device 3 112.10.39.255 Shou mountain region of Hangzhou city
Client device 4 221.226.140.255 Nanjing's Xuan Wu Ou
Client device 5 218.82.20.255 Shanghai city still district
In step 302, the dns server determines, from the node server cluster, the target node server according to the location information of the client device.
In the embodiment of the invention, the DNS server can be used for providing a corresponding node server for any client device in the client cluster. As shown in fig. 4, another system architecture schematic diagram provided in an embodiment of the present invention, where the system architecture 100 includes a cloud storage device 101, a node server cluster 102, a client cluster 103, and a DNS server 104. The DNS server 104 is connected to the client cluster 103 and the node server cluster 102, so that the DNS server 104 can determine a corresponding node server (such as the node server 1021) from the node server cluster 102 according to the location information of any client device (such as the client device 1031) in the client cluster 103, and further, the client device 1031 can communicate with the node server 1021.
For example, taking the client device 1 shown in table 1 as an example, the location information corresponding to the client device is a Shanghai city Min line area, the DNS server may screen out the node server cluster that both the location information is a Shanghai city Min line area, and use this node server as the node server corresponding to the client device 1.
In step 303, the dns server sends a response message for the upload request to the client device, where the response message includes location information of the target node server.
In step 304, the client device receives a response message of the upload request sent by the DNS server.
In step 305, the client device sends the upload file to the target node server according to the location information of the target node server.
It should be noted that the methods described in steps 301 to 305 are only examples, and in other possible examples, those skilled in the art may determine the target node server according to experience and actual situations, for example, may determine the target node server according to load information of the node servers in the node server cluster, which is not limited in particular.
In step 201, for a client cluster, all files uploaded by the client cluster may be regarded as an uploaded file set, and the files uploaded by each client in the client cluster are files in the uploaded file set, and each file in the uploaded file set corresponds to the same data body.
The data body may refer to a type corresponding to each file, such as a company type, an industry type, etc., and may be determined by a person skilled in the art according to actual situations. For example, if the uploading file 1 is a file of company a, the data entity corresponding to the uploading file 1 may be company a; the uploading file 2 is a file in the B domain, and the data entity corresponding to the uploading file 2 may be the B domain.
In step 202, the meta information is generated according to the upload file, and the meta information may include a data body to which the upload file belongs, or may include an upload file identifier, or may include location information of the node server, which is not specifically limited.
In the implementation process, the node server can directly take the data main body to which the uploading file belongs, the uploading file identifier and the position information of the node server as meta information; alternatively, the node server may encrypt the data body to which the uploaded file belongs, the uploaded file identifier, and the location information of the node server, and use the encrypted information as meta information, which is not specifically limited.
In step 203, the node server may directly send the uploaded file and the meta information to the cloud storage device together; or the node server can send the meta information to the cloud storage device first and then send the uploading file to the cloud storage device; the node server may also send the uploaded file to the cloud storage device within a set time after receiving the uploaded file. Specifically, as shown in fig. 5, a flow chart corresponding to a method for synchronizing files by a node server according to an embodiment of the present invention includes the following steps:
In step 501, a node server sends a synchronization request to a cloud storage device, the synchronization request including meta-information.
In step 502, the cloud storage device receives a synchronization request sent by a node server.
In step 503, after determining that there is available transmission bandwidth, the cloud storage device returns a response message of the synchronization request to the node server.
Before the cloud storage device returns the response message of the synchronization request to the node server, the cloud storage device can also judge whether available transmission bandwidth exists, and return the response message to the node server under the condition that the available transmission bandwidth exists, so that the rate of the node server sending the uploaded file to the cloud storage device can be improved.
And step 504, after receiving the response message of the synchronization request, the node server sends an uploading file to the cloud storage device.
Therefore, the node server can send the meta-information to the cloud storage device, and the meta-information is smaller than the uploaded file, so that the meta-information can be quickly transmitted to the cloud storage device, and the uploaded file is retransmitted under the condition that the bandwidth is enough, so that the file transmission efficiency is improved.
After executing step 204, the node server may also delete the uploaded file and meta information, so that the storage burden of the node server can be reduced, and the problem of duplication of file contents stored in the cloud storage device and the node server is avoided.
Embodiment two:
based on the system architecture shown in fig. 1, fig. 6 illustrates a flow diagram corresponding to another file transmission method according to an embodiment of the present invention, which specifically includes the following steps:
in step 601, the client device sends a download request to the cloud storage device, where the download request includes a target file identifier.
In step 602, the cloud storage device receives a download request sent by the client device.
In step 603, if the cloud storage device determines that the target file corresponding to the target file identifier is not stored, determining the location information of the target node server according to the correspondence between the file identifier and the location information of the node server.
In step 604, the cloud storage device sends a response message of the download request to the client, where the response message includes location information of the target node server.
Step 605, the client device receives a response message of the download request sent by the cloud storage device, and obtains the target file from the target node server according to the location information of the target node server included in the response message.
It should be noted that, the above-mentioned step 601 and step 605 may be performed by any client device in the client cluster 103 shown in fig. 1, for example, may be performed by the client device 1031 shown in fig. 1; the above steps 602 to 604 may be performed by the cloud storage apparatus 101 shown in fig. 1.
Therefore, when the client device downloads the target file, if the file is not synchronously stored in the cloud storage device, the client device can still download the target file from the corresponding node server, so that the situation that the file is not synchronous or the client device cannot download the target file in the file synchronization process is avoided.
Specifically, in step 603 and step 604, if the cloud storage device determines that the target file corresponding to the target file identifier is stored, the target file may be directly sent to the client, so that when the client device downloads the target file, if the file is already stored in the cloud storage device synchronously, the client device may directly obtain the target file.
In other possible embodiments, any information related to the target file identifier may not be stored in the cloud storage device, in other words, there is no target file corresponding to the target file identifier in the cloud storage device, and no node server corresponding to the target file identifier, so that information that the file does not exist may be returned to the client device.
In the specific implementation process, the client can be set to be directly connected with the cloud storage device when the downloading function is started; when the cloud storage device determines that the target file is not stored, the management server can also determine the position information of the target node server corresponding to the target file.
In order to more clearly describe the file transfer method, the flow involved in the second embodiment of the present invention will be described in detail with reference to fig. 7. As shown in fig. 7, the following steps may be included:
in step 701, a client device sends a download request to a cloud storage device, where the download request includes a target file identifier.
In step 702, the cloud storage device receives a download request sent by the client device.
Step 703, the cloud storage device determines whether a target file corresponding to the target file identifier is stored according to the target file identifier, and if so, executes step 704; if not, step 706 is performed.
In step 704, the cloud storage device sends the target file to the client.
In step 705, the client device receives the target file sent by the cloud storage device.
Step 706, the cloud storage device determines whether there is a target node server corresponding to the target file identifier according to the correspondence between the file identifier and the location information of the node server, and if so, executes step 707; if not, step 710 is performed.
In step 707, the cloud storage determines location information of the target node server.
In step 708, the cloud storage device sends a response message of the download request to the client, where the response message includes location information of the target node server.
In step 709, the client device receives a response message of the download request sent by the cloud storage device, and obtains the target file from the target node server according to the location information of the target node server included in the response message.
In step 710, the cloud storage device returns information that the file does not exist to the client device.
It should be noted that the above step numbers are only exemplary representations of one execution flow, and the sequence of each step is not specifically limited in this application. For example, in the above steps 703 and 706, the cloud storage device may determine whether there is a target node server corresponding to the target file identifier according to the correspondence between the file identifier and the location information of the node server, and then determine whether there is a target file corresponding to the target file identifier according to the target file identifier, which is not particularly limited.
