Method embodiment

FIG. 1 is a flow chart of a virtual network hard disk mounting method applied to a local area network server according to an embodiment of the present invention. The embodiment of the present invention provides a virtual network hard disk mounting method, which is applied to a local area network server and a user terminal through a local area network server. The mount request is received and judged whether the user terminal can be mounted, and the virtual network hard disk is locally mapped and generated on the user terminal after the mount is allowed. The method includes:

Step 101: Receive a mount request sent by the first user terminal in the local area network.

Here, in the local area network, the local area network server and the user terminal may adopt a private protocol including a control channel and a data channel, and the control channel is connected by a binary message transmission control protocol (Tcp), and the data channel is connected by a binary coded http message. The LAN server receives the mount request sent by the user terminal through the control channel. The first user terminal here represents the user terminal currently requested to be mounted.

Step 102: Determine, according to the mount request, whether the first user terminal is allowed to be mounted.

Step 103: When the first user terminal is allowed to be mounted, generate a first virtual network hard disk for the first user terminal mapping, wherein one virtual network hard disk can only be mounted on one user terminal at the same time.

Here, when the local area network server allows the user terminal to mount, the corresponding data file on the local area network server is mapped locally on the user terminal to generate a virtual network hard disk, so that the virtual network hard disk is formed by the hard disk locally in the user terminal, so that the user can be at the user terminal. Directly perform local operations on the data in the virtual network hard disk, that is, each time the user reads and writes data, it is completed locally. Of course, the actual mount action is implemented by the bus driver. The LAN server transmits data to the virtual network hard disk generated by mapping on the user terminal through the data channel. Include the actual data storage bit in the LAN server Set, the size of the allocated space, the registered terminal information, the current virtual network disk status and other information. It should be noted that a plurality of virtual network hard disk files are stored on the local area network server, and each virtual network hard disk file can be attributed to multiple users, and each user can log in online at multiple different user terminals, but only allowed at the same time. A user successfully mounts the corresponding virtual network hard disk file on a user terminal, and maps to generate a virtual network hard disk. That is, a virtual network hard disk can only be mounted on one user terminal at the same time, thereby performing data on the virtual network hard disk. Read and write operations. In this way, to ensure that user access does not conflict, and also ensure that the data after the user changes and updates the data of the virtual network hard disk is consistent.

As an optional implementation manner of the present invention, in step 102, the step of determining whether to allow the first user terminal to be mounted according to the mount request includes:

Here, when the local area network server determines whether the user terminal is allowed to perform the mount, that is, whether the other user terminal is currently mounted, the local area network server determines that the user terminal is allowed to be mounted after determining that no other user terminal is currently mounted.

As an optional implementation manner of the present invention, in step 102, the step of determining whether to allow the first user terminal to be mounted according to the mounting request may further include:

When other user terminals are currently mounted, the first uninstall request is sent to other user terminals, and when the other user terminals successfully uninstall according to the uninstall request, it is determined that the first user terminal is allowed to be mounted.

Here, when other user terminals are mounted in the local area network, the local area network server sends the MAC (Medium/Media Access Control) address of the already installed user terminal to all the currently online user terminals including the first user terminal, and simultaneously An unloading request is sent to the user terminal that has been mounted, indicating that the currently online user terminal has a user terminal being mounted, and when no user is mounted, the MAC address is empty. Here, the already mounted user terminal judges based on the working state of the current virtual network hard disk, wherein the working state of the virtual network hard disk includes idle, reading, and writing. When the virtual network hard disk of the already mounted user terminal is in an idle state, the local area network server receives the accepting offload response sent by the local area network server, and when the already mounted user terminal successfully uninstalls according to the uninstall request, the local area network server determines to allow the first The user terminal is mounted. When the virtual network hard disk of the already mounted user terminal is in the non-idle state, the local area network server receives the response rejecting the uninstallation, and the local area network server sends a response to the first user terminal that the mount request failed, so that the first user terminal gives up. Mount.

As a further embodiment of the embodiment of the present invention, after the first user terminal is successfully mounted and the local read/write operation is completed, the method may further include:

Receiving a second uninstall request sent by the first user terminal.

Here, after the user terminal is successfully mounted, and the user completes the read/write operation locally at the user terminal, the user issues a second uninstall request through the user terminal, and the local area network server receives the second uninstall request of the user terminal through the control channel. Here, the second offload request is an offload request issued by the user terminal to distinguish the first offload request issued by the local area network server in the foregoing embodiment.

And according to the second uninstall request, causing the first user terminal to upload the current modified data to the local area network server, and determining to allow the first user terminal to uninstall.

Here, in order to ensure the consistency of data in the local area network server after the data in the current virtual network hard disk is modified, the local area network server synchronizes the current modified data to the local area network server after receiving the second unloading request sent by the user terminal.

As an optional implementation manner of the present invention, after the first user terminal is configured to be configured to generate the first virtual network hard disk for the first user terminal, the method may further include:

It is determined whether the data on the first virtual network hard disk has a cache on the first user terminal.

Here, the virtual network hard disk mounted on the user terminal includes several types, such as a network disk, a half-cache network disk, and a full-cache network disk. When the virtual network disk belongs to a half-cache network disk or a full-cache network disk type, the user terminal There is data cache in the memory and local hard disk; when the virtual network disk belongs to the full cache network disk type, it can be used offline on the user terminal; and when the virtual network disk belongs to the network disk type, it is read and written every time on the user terminal. Need to consume network traffic.

When the judgment result is yes, the data of the local area network server is synchronously updated to the first user terminal.

Here, when it is determined that the virtual network hard disk belongs to the half-cache network disk or the full-cache network disk, the data of the local area network server needs to be synchronously updated to the user terminal when used on the user terminal to ensure data consistency.

Preferably, in the above embodiment, the step of synchronously updating data of the local area network server to the user terminal includes:

It is determined whether the master boot record (MBR) of the first virtual network hard disk is empty, and when the MBR data is not empty, the data of the local area network server is updated to the user terminal.

Here, since the virtual network hard disk is the virtualization of the entire hard disk, the MBR data of the virtual network hard disk is judged. When the MBR data data is empty, that is, the data of the local area network server is not modified and updated, the local area network server does not need to be on the user terminal. The data is updated, and when the MBR data is not empty, the data of the LAN server is updated to the user terminal to ensure the consistency of the data.

The virtual network hard disk mounting method of the embodiment of the present invention as shown in FIG. 2 is applied to the flow chart of the user terminal, and the embodiment of the present invention further provides a method corresponding to the virtual network hard disk mounting method applied to the local area network server. A virtual network hard disk mounting method is applied to a user terminal, and the method includes:

Step 201: Send a mount request to the local area network server, so that the local area network server determines whether the user terminal is mounted according to the mount request.

Here, in the local area network, the local area network server and the user terminal may adopt a private protocol including a control channel and a data channel, and the control channel is connected by a binary message transmission control protocol Tcp, and the data channel is connected by a binary coded http message, and the user terminal passes the control channel. Send a mount request to the LAN server.

Step 202: Receive a mount request response that the local area network server allows to mount.

Here, the user terminal receives the mount request response sent by the local area network server through the control channel.

Step 203: Generate a virtual network hard disk according to the local mapping in response, wherein one virtual network hard disk can only be mounted on one user terminal at the same time.

Here, the user terminal receives a MAC address sent by the local area network server, and determines whether the MAC address is the MAC address of the local end of the user terminal. When the determination is yes, the user terminal performs mounting, and generates a virtual network hard disk locally, so that the user The data in the virtual network hard disk can be directly operated locally on the user terminal, that is, each time the user reads and writes data, it is completed locally. It should be noted that a plurality of virtual network hard disk files are stored on the local area network server, and each virtual network hard disk file can be attributed to multiple users, and each user can log in online at multiple different user terminals, but only allowed at the same time. A user successfully mounts the corresponding virtual network hard disk file on a user terminal, and maps to generate a virtual network hard disk. That is, a virtual network hard disk can only be mounted on one user terminal at the same time, thereby performing data on the virtual network hard disk. Read and write operations. In this way, to ensure that user access does not conflict, and also ensure that the data after the user changes and updates the data of the virtual network hard disk is consistent.
