Description

Cross-local area network file storage method and system, storage medium and terminal

Technical Field

The invention relates to the technical field of data circulation, in particular to a cross-local-area-network file storage method and system, a storage medium and a terminal.

Background

With the continuous development of ethernet technology and Internet (Internet, also called Internet) services, various file storage systems are continuously developed to adapt to file uploading and downloading under different network scenes.

The existing file storage system is designed to take high performance and high reliability as the primary targets for realization. When the file storage system is constructed, a designer can directly connect the file storage system with an application server or can interconnect the file storage system with an application user in a local area network through a network topology structure.

The existing file storage system does not support the operations of file storage, safety control and the like across the local area network area. Under certain specific network structures, in order to meet the requirement that users in an intranet and an extranet of a part of files can upload and download, the file storage system is placed in an internal subnet area. In order to ensure the safety protection requirement of the internal subnet, the connection route only opens a fixed network port to an external network. Therefore, when a user in a network area different from the file storage system acquires a file, a large amount of file transmission flow can be generated on a connection route leading to the file storage system, the network load of the subnet is increased, the abnormal flow behavior detection of the subnet is influenced, and potential safety hazards are generated.

If the file storage system is arranged in an external subnet, an intranet user can acquire a file with authority given by the intranet user only by accessing the external subnet through network routing, so that the uploading and downloading processes of the file server and part of sensitive storage files do not accord with the requirement of intranet safety risk.

Therefore, for a file storage system user in a cross-local area network environment, the existing file storage system function cannot simultaneously meet the requirements of the user on high performance, high availability, network security and file privacy sensitivity.

Specifically, after the file requested to be uploaded by the user is stored in the local network area, the file is synchronized to other network areas in the plurality of network areas, so that the file storage across the network areas is possible. Further, the synchronization operation described in this embodiment is also beneficial to implement disaster recovery backup of files in different network areas to a certain extent.

Further, for each network area, since the file uploaded to any network area of the plurality of network areas is synchronized to each network area in advance, in the downloading stage, the user in any network area can download the required file from the local network area without connecting to other network areas to download the file. Therefore, according to the scheme of the embodiment, the user basically does not perceive the cross-network-area limitation of the file operation.

Compared with the existing file storage system only built in a single network area, the file storage system of the embodiment builds the file storage module and the control scheduling module in each network area, the control scheduling module of each network area controls the respective file storage module to synchronously store the files of the other party, and users in different network areas access the own control scheduling module and the file storage module to acquire the files uploaded by the network area or synchronously sent by other network areas. Therefore, the embodiment provides the lightweight file storage system which can simultaneously meet the requirements of high performance, high availability, network security and file privacy sensitivity for the heterogeneous network environment meeting the specific security access requirement.

Furthermore, the scheme of the embodiment can realize the functions of controllable uploading and downloading of users in the intranet zone with higher network security requirements, controllable uploading and downloading of users in the extranet zone with lower security requirements and controllable uploading and downloading in the cross-network zone after the permission verification.

Further, the modules in the file storage system are separated and decoupled, and the file storage system is light in weight and easy to deploy and maintain.

Taking a cross-local-area-network environment including an extranet and an intranet as an example, a file uploaded by an extranet user is stored in the extranet and synchronized to the intranet, and similarly, a file uploaded by an intranet user is stored in the intranet and synchronized to the extranet. The extranet user can directly acquire the file uploaded by the intranet user in the extranet without being connected to the intranet for file downloading, and the access burden of the intranet and an externally connected port is reduced. Similarly, an intranet user can directly acquire a file uploaded by an extranet user in an intranet, and the requirement of the intranet user on network security and file privacy sensitivity is met as the downloading operation is completed in an intranet environment.

Detailed Description

As background, for file storage system users in a cross-LAN environment, the existing file storage system functions cannot simultaneously satisfy the requirements of such users on high performance, high availability, network security, and sensitivity to file privacy.

The inventor of the application discovers, through analysis, that the existing file storage system is only established in a single network area and cannot give consideration to high performance, high availability and network security. Specifically, the file storage system established in the intranet zone greatly increases the load of the connection route when receiving the access of an external user, and the file storage system established in the extranet zone cannot meet the requirement of intranet security risk.

To solve the foregoing technical problem, an embodiment of the present invention provides a method for storing a file across a local area network, including: receiving an uploading request and a file to be stored, wherein the uploading request comprises storage information and synchronous information of the file to be stored; storing the file to be stored in a local network area according to the uploading request; sending a synchronization instruction to other network areas according to the synchronization information, wherein the synchronization instruction comprises the file to be stored and the storage information of the file to be stored; and receiving synchronization completion information, wherein the synchronization completion information is used for indicating that the file to be stored is stored in the other network areas.

According to the scheme, the lightweight file storage under the cross-local area network environment can be realized, the high availability and the network security are both considered, and the requirement of a user on the privacy sensitivity of the file is met. Specifically, after the file requested to be uploaded by the user is stored in the local network area, the file is synchronized to other network areas in the plurality of network areas, so that the file storage across the network areas is possible. Further, the synchronization operation described in this embodiment is also beneficial to implement disaster recovery backup of files in different network areas to a certain extent.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a block diagram of a file storage system across a local area network according to an embodiment of the present invention.

Specifically, the cross-local area network refers to file storage and downloading in a plurality of network areas, and the network areas may refer to local area networks or other similar network areas. The file uploaded to the specific network area is synchronized to other network areas, so that users with corresponding rights in other network areas can also acquire the file. Further, with the file storage system according to this embodiment, when downloading the file uploaded to the specific network area, other network areas do not need to be connected to the specific network area, but can complete the downloading operation in the current network area.

The plurality of mesh zones may include an outer mesh zone and an inner mesh zone. Wherein, the extranet area may be: and the local area network is connected with the wide area network, provides network service for external users, and can bear local area network subnets with higher bandwidth. The intranet zone may be: the local area network subnet has high safety protection requirements and strict traffic access monitoring. The internal network area can carry out limited network communication with the external network area, and the bearable bandwidth is lower.

In a specific implementation, referring to fig. 1, the file storage system 1 across the local area network (hereinafter referred to as the file storage system 1) according to this embodiment may include: the system comprises a first network area control scheduling module 10, a first network area file storage module 11, a second network area control scheduling module 12 and a second network area file storage module 13.

The first network area control scheduling module 10 and the first network area file storage module 11 are arranged in the first network area 14. The second network area control scheduling module 12 and the second network area file storage module 13 are arranged in the second network area 15. In other words, in terms of system architecture, the file storage system 1 in this embodiment deploys a set of control scheduling module and a set of file storage module in the first network area 14 and the second network area 15, respectively. According to the user requirements, each module supports high-performance deployment and expansion.

One of the first and second mesh zones 14, 15 may be the outer mesh zone and the other may be the inner mesh zone.

In one specific implementation, the file storage system 1 may further include a connection route 16, and the first network area control scheduling module 10 and the second network area control scheduling module 12 may communicate through the connection route 16. Specifically, the connection route 16 may be a gateway route that performs connection control between the first network area 14 and the second network area 15. Further, the file storage system 1 realizes a cross-network-area file synchronization function through a connection route 16 port.

Therefore, the scheme of the embodiment provides the file storage system 1 in the cross-local area network environment, and users in different network areas can obtain high-performance file services by deploying the file storage system 1.

In a specific implementation, the first network area control scheduling module 10 and the first network area file storage module 11 are decoupled separately, and similarly, the second network area control scheduling module 12 and the second network area file storage module 13 are decoupled separately, which is beneficial to adjusting or expanding functions of each module according to user requirements in actual use. For example, the first network area control module 10 and the first network area file storage module 11 may be respectively deployed in different servers. Similarly, the second network area control scheduling module 12 and the second network area file storage module 13 may also be deployed in different servers respectively.

The following is a detailed description of the file uploading process initiated by the user in the first network zone 14.

In one implementation, referring to fig. 1 and 2, a user 17 located in the first network area 14 (hereinafter referred to as a first network area user) may perform operation s1 to send an upload request and a file to be stored to the first network area control scheduling module 10 located in the same network area.

The upload request may include an upload permission authentication, and the control scheduling module receiving the upload permission authentication may verify whether the user sending the upload request has a permission to upload a file using the current interface.

The upload request may further include storage information of the file to be stored, and the file storage system 1 may determine a storage location of the file to be stored according to the storage information. For example, the storage information of the file to be stored may include: the accessible user permission type of the file to be stored and the type of the file to be stored. Wherein, the accessible user permission category can be related to a specific file storage path; the category to which the file to be stored belongs may include information such as a file attached directory to indicate a scene classification required by the user who sends the upload request.

The upload request may further include synchronization information of the file to be stored, so as to indicate whether the file to be stored needs to be synchronized in multiple network areas.

In one implementation, with continued reference to fig. 1 and 2, the first network zone control scheduling module 10 may include an authority verification unit (not shown), and in response to receiving the upload authority authentication, the authority verification unit of the first network zone control scheduling module 10 may perform operation s2 to verify whether the user sending the upload request has the upload authority according to the upload authority authentication.

For example, the upload authority authentication may be carried in the form of a token (token), and the first network area control scheduling module 10 may store tokens of all users having upload authority in the first network area 14. In response to receiving the upload request sent by the first network area user 17, the authority verification unit may compare the token in the upload request with all pre-stored tokens of users having the upload authority to determine whether the first network area user 17 has the upload authority.

And if the token in the uploading request is matched with one of the pre-stored tokens of all the users with the uploading authority, the verification is passed.

In one implementation, the first network area control scheduling module 10 may include: a buffer unit (not shown) configured to buffer a received file to be stored locally in the first network area control scheduling module 10.

For example, when the verification passes, the caching unit of the first network area control scheduling module 10 may perform operation s3 to cache the file to be stored to the local after receiving the file to be stored, so as to generate a temporary file.

In one specific implementation, the first network area control scheduling module 10 may further perform operation s4 to call the first network area file storage module 11 to store the file to be stored according to the upload request.

Specifically, the first network area control scheduling module 10 may include a file access task scheduling unit (not shown), and the operation s4 may specifically include: the file access task scheduling unit sends the file to be stored and the storage information of the file to be stored to the first network area file storage module 11. In response to receiving the file to be stored and the storage information thereof, the first network area file storing module 11 may execute operation s5 to store the file to be stored in the first network area 14 according to the storage information of the file to be stored.

For example, the first network area file storage module 11 may determine a storage path of the file to be stored in the first network area 14 according to the accessible user permission category and the category to which the file to be stored belongs, and store the file to be stored according to the determined storage path in the first network area 14.

In one embodiment, the first network area file storage module 11 may perform a small file merging operation on the files stored in the first network area 14 according to the storage condition thereof and the related configuration. Therefore, the problem that the number of files stored in a single server is limited can be solved.

For example, when storing, a plurality of files are spliced to form a large file, and when a user needs to download a certain file, the large file is disassembled to restore to a plurality of original small files.

In a specific implementation, the first network area file storage module 11 may perform the same file deduplication operation on the files stored in the first network area 14 according to the storage condition of the first network area file storage module and the related configuration, so as to achieve storage optimization.

In a specific implementation, after the file to be stored is stored in the first network area 14 according to the storage information of the file to be stored, the first network area file storage module 11 may further update the meta information of the file to be stored to a file meta information table, where the file meta information table is used to record the identifier and the meta information of the file stored in the local network area, and an association relationship between the identifier and the meta information.

In particular, the file meta-information table may also be referred to as a file meta-information key-value lookup table.

For example, the file meta information table may record the identification, meta information and association relationship between the two of each file stored in the first network area 14 in the form of key value pairs. Wherein, the key is the identification of the file, and the value is the meta information of the file. A single key may correspond to multiple value fields.

The identification of the file is unique and can be used for uniquely determining the file. For example, the identification of the file may be a hash value generated based on a full path of the file. In practical applications, the identifier of the file may also be generated or determined in other manners.

The meta information of the file may include: the storage path of the file, whether the file needs to be synchronized, the authority of an accessible user of the file, the verification information of the file, the statistical information corresponding to the file, and the like.

The file meta information table may be stored in the first network area control scheduling module 10, or may be stored in the first network area file storage module 11. Alternatively, the file meta information table may also be stored in an external server, and the first network area file storage module 11 may access the external server to obtain and update the file meta information table.

In a specific implementation, the first network area file storage module 11 may be deployed in a server cluster, and for a server that receives a file to be stored and storage information thereof sent by the file access task scheduling unit, after the server completes a storage operation, the server may trigger high-availability synchronization of the same network area for physically storing the file to be stored, so as to perform a synchronization operation in the first network area 14.

In one embodiment, after completing the storage task, the first network area file storing module 11 may execute operation s6 to send confirmation information and file obtaining manner information of the file to be stored in the first network area 14.

Specifically, the file obtaining manner information may include: the full path of the file to be stored in the first network area 14, the identifier of the file to be stored, the uploading time of the file to be stored, and the like.

The confirmation information may be used to inform the first network area control scheduling module 10 that the file to be stored is stored in the first network area 14.

In response to receiving the confirmation information, the file access task scheduling unit may record the current storage operation and trigger a checking operation s7 to check whether the file to be stored needs to be synchronized across network zones.

Specifically, in response to that the file to be stored is stored in the first network area 14, the first network area control scheduling module 10 may execute operation s8 to send a synchronization instruction according to the synchronization information, where the synchronization instruction includes the file to be stored and the storage information of the file to be stored.

For example, when the synchronization information indicates that the file to be stored needs to be synchronized across network zones, the first network zone control scheduling module 10 may generate the synchronization instruction according to the temporary file cached in operation s3 and the storage information of the temporary file except the synchronization information through the connection route 16, and send the synchronization instruction to the second network zone control scheduling module 12.

The synchronization information of the file to be stored is not sent to prevent two network areas from circularly synchronizing the same file.

In a specific implementation, the second network area control scheduling module 12 receives the synchronization instruction, and calls the second network area file storage module 13 to store the file to be stored according to the synchronization instruction.

Further, the second network area file storage module 13 stores the file to be stored in the second network area 15 according to the storage information of the file to be stored.

The specific structure of the second network area control scheduling module 12 may be the same as that of the first network area control scheduling module 10. The synchronization command may be regarded as a phase-change upload request, and the second network partition control scheduling module 12 receiving the synchronization command may execute the upload file storage logic with reference to the operations s3 to s6 to call the second network partition file storage module 13 to synchronously store the file to be stored indicated by the synchronization command in the second network partition 15.

In response to that the file to be stored is stored in the second network area 15, the second network area control scheduling module 12 may execute operation s9 to send synchronization completion information, where the synchronization completion information is used to indicate that the file to be stored is stored in the second network area 15.

In response to receiving the synchronization completion information, the first network area control scheduling module 10 may perform operation s10 to update the file meta information table, and update the synchronization status of the file to be stored to be synchronized.

In one specific implementation, in response to receiving the synchronization completion information, the first network area control scheduling module 10 may execute operation s11 to send upload success information to the user sending the upload request (i.e., the first network area user 17), where the upload success information includes file obtaining manner information of the file to be stored in the first network area 14.

In a variation, the first network area control scheduling module 10 performs synchronization check on the synchronization completion information, and if the check result indicates that the synchronization is failed, the first network area control scheduling module 10 may wait for a preset time and then execute the operation s9 again until the synchronization is successful.

Therefore, the file uploaded by the user in the first network area 14 is synchronously stored in the second network area 15, so that the user with corresponding authority in the two network areas can acquire the file in the network area of the user without crossing to another network area for file downloading operation.

The following is a specific description taking an example of a file downloading process initiated by a user in the second network area 15.

In one implementation, referring to fig. 1 and 3, a user (hereinafter referred to as a second network area user) 18 located in the second network area 15 may perform an operation sa to send a download request to the second network area control scheduling module 12 located in the same network area.

The download request may include a download right authentication, and similar to the upload right authentication, the control scheduling module receiving the download right authentication may verify whether the user sending the download request has the right to download the file using the current interface.

The download request may further include file acquisition mode information of the file requested to be downloaded by the second network area user 18. The file acquisition mode information may be selected from: the storage path of the file pointed by the download request, the identification of the file pointed by the download request, the accessible user permission category of the file pointed by the download request and the category to which the file pointed by the download request belongs.

The second network area user 18 may obtain the file obtaining mode information of the file from the user who uploaded the file, or through other means.

In response to receiving the download request, the second network area control scheduling module 12 may perform operation sb to invoke its permission verification unit to verify whether the user sending the download request (i.e., the second network area user 18) has the download permission according to the download permission authentication.

When the verification is passed, the second network area control scheduling module 12 may search in a local cache unit according to the file obtaining mode information of the file requested to be downloaded, and if the temporary file of the file can be obtained, directly obtain the file from the cache unit and return the file to the second network area user 18.

In a specific implementation, the meta information of the file may record statistical information of the download frequency of the file, and the scheduling control module may determine a lifetime of the temporary file corresponding to the file in the local cache according to the download frequency of each file.

If the cache unit does not have the file pointed by the download request, the file access task scheduling unit of the second network area control scheduling module 12 may obtain the file pointed by the download request from the associated file storage module. The associated file storage module is a file storage module in the same network area as the control scheduling module that receives the download request, in the embodiment, the second network area file storage module 13, of the first network area file storage module 11 and the second network area file storage module 13.

Specifically, the file storage module may execute an operation sc to send the received file obtaining manner information of the file requested to be downloaded to the second network area file storage module 13.

The second network file storage module 13 may execute operation sd to determine the file pointed by the download request and/or the storage path of the file pointed by the download request according to the received file obtaining manner information. According to the determined information, the second network file storage module 13 may obtain the physical storage location of the file, and further obtain the file pointed by the download request.

Further, the second network area file storage module 13 may execute operation se to transmit the acquired file back to the second network area control scheduling module 12.

In response to receiving the file, the second network area control scheduling module 12 may execute operation sf to call the file access scheduling unit to record the file download event.

Further, the second network area control scheduling module 12 may perform an operation sg to send the file to the second network area user 18.

In this embodiment, the file pointed by the download request may be a file uploaded to the local network area or a file synchronized to the local network area by another network area, where the local network area refers to a network area where the control scheduling module receiving the download request is located.

In this way, no matter the user in the current network area uploads the file in the current network area or the user in another network area uploads the file in another network area, because the file storage system of this embodiment synchronizes the files in different network areas in a plurality of network areas, the user in the current network area can obtain the file uploaded by the user in another network area without crossing the network areas.

Therefore, the control scheduling module can realize the control of uploading requests, downloading requests and whether to perform cross-network-area synchronization of files. The control scheduling module can also realize a file access task scheduling function, and the function can initiate tasks of storing and downloading files to the file storage module, so that the overall reliability of the file storage system 1 is improved. The control scheduling module can also realize the function of scheduling the file synchronization task, and the function can initiate the cross-network file synchronization task. The overall reliability of the file storage system 1 is improved. The control scheduling module can also realize the state management function of the file storage element information in the local network area, and the function can establish a key value table for the files stored in the file storage system 1, manage the storage state of the files through the key value table, and optimize uploading, downloading, checking and error correction of the files. The control scheduling module can also realize a synchronous check function, which can enable the file storage system 1 to initiate synchronous check on cross-network area synchronous files in idle time, repair synchronous abnormal files and alarm abnormal. The control scheduling module can also realize a file access record analysis function, which can record the uploading and downloading operations of the files and set the effective time for updating the file cache according to the service state, the downloading frequency and the like.

The file storage module can realize duplicate removal and small file combination of the same file to realize a series of functions such as storage optimization, load balancing, multi-machine synchronization in the same network area of the file, key value updating and searching of file meta information and the like.

By adopting the scheme of this embodiment, the file storage system 1 establishes the file storage module and the control scheduling module in each network area, the control scheduling module of each network area controls the respective file storage module to store the file of the other party synchronously, and the users in different network areas access the control scheduling module and the file storage module of the own party to acquire the file uploaded by the local network area or synchronously sent by other network areas. Therefore, the embodiment provides the lightweight file storage system which can simultaneously meet the requirements of high performance, high availability, network security and file privacy sensitivity for the heterogeneous network environment meeting the specific security access requirement.

Furthermore, the scheme of the embodiment can realize the functions of controllable uploading and downloading of users in the intranet zone with higher network security requirements, controllable uploading and downloading of users in the extranet zone with lower security requirements and controllable uploading and downloading in the cross-network zone after the permission verification.

Further, the modules in the file storage system are separated and decoupled, and the file storage system is light in weight and easy to deploy and maintain.

Taking a cross-local-area-network environment including an extranet and an intranet as an example, a file uploaded by an extranet user is stored in the extranet and synchronized to the intranet, and similarly, a file uploaded by an intranet user is stored in the intranet and synchronized to the extranet. The extranet user can directly acquire the file uploaded by the intranet user in the extranet without being connected to the intranet for file downloading, and the access burden of the intranet and an externally connected port is reduced. Similarly, an intranet user can directly acquire a file uploaded by an extranet user in an intranet, and the requirement of the intranet user on network security and file privacy sensitivity is met as the downloading operation is completed in an intranet environment.

By the file storage system 1 in this embodiment, on the premise of ensuring the security requirement, the user can perform controllable recorded high-performance file uploading, file downloading, and file synchronization in both the intranet zone and the extranet zone.

By analyzing the access records of the file storage system 1, the business level optimization for the file service can be realized. And realizing the disaster recovery backup of files in different network areas to a certain extent.

According to the scheme of the embodiment, decoupling separation of file authority authentication, file storage optimization, file synchronization functions and the like in the file storage system 1 is achieved, and subsequent modularized function replacement and upgrading of the file storage system 1 are facilitated.

In a variation of this embodiment, the step s3 may be omitted, that is, the uploaded file to be stored may be stored directly by the first network file storage module 11 without being cached.

Correspondingly, in the downloading stage, the control scheduling module receiving the downloading request can directly obtain the file pointed by the downloading request from the associated file storage module.

In a variation, the step s2 may be omitted, that is, the control scheduling module may perform the storage operation on the received file to be stored without verifying the user authority.

Correspondingly, in the downloading stage, the control scheduling module receiving the downloading request also directly sends the file requested to be downloaded by the user to the user without verifying the authority of the user.

In this variation, the authority of the user sending the upload request and/or the download request may implicitly realize the verification through the message sending behavior of the user. For example, the file storage system 1 only allows users with corresponding permissions to access the control scheduling module in the network area where the users are located, and only users with uploading permissions and/or downloading permissions can send uploading requests and/or downloading requests to the control scheduling module in the network area where the users are located.
