Description

Technical Field

[0001] The present disclosure relates to the technical field of data transmission, and in particular to a data transmission method, a first virtual machine, a virtual desktop management server and a system. Background Art

[0002] The basic structure of the existing VDI system can be referred to Figure 1 .like Figure 1 As shown, the VDI system is based on the Wanxiang VGTP image transmission protocol, and mainly includes a zero terminal (built-in VGTP-R terminal, referred to as R terminal) and a cloud server terminal (built-in VGTP-S terminal, referred to as S terminal). Among them, the R terminal is used to receive images from the cloud desktop, and at the same time transmit the local mouse and keyboard information back to the cloud, and the cloud is injected into the cloud desktop corresponding to the current R terminal. The cloud desktop is generated by the virtual machine / physical machine (VM / PM) assigned by the cloud server to the current zero terminal; the S terminal is an image acquisition and encoding unit running in the cloud virtual OS, and is also responsible for the injection function of user input data. The cloud server is generally based on the IAAS architecture and is a server with a strong virtual host. It can provide management functions for multiple virtual machines through the hypervisor and provide a hardware environment for VM / PM to run.

[0003] The above VDI system has been widely used in fields such as office and games.

[0004] In some scenarios, a virtual machine user needs to transfer files to another virtual machine user. In the prior art, for such scenarios, the sending virtual machine generally sends the file to be transferred to the receiving virtual machine through instant messaging software. For example, when virtual machine A needs to send a file to virtual machine B, it needs to first obtain information such as the IP port of virtual machine B from the communication software, and then virtual machine A determines the location of B through routing calculation, and then transmits it through the file transfer protocol. This method is relatively traditional and does not take into account the characteristics of the cloud desktop architecture itself. Summary of the invention

[0100] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0101] Figure 1 A flowchart of a data transmission method provided by an embodiment of the present disclosure. Figure 1 As shown, the method is applied to a first virtual machine, and includes:

[0102] Step 101: Send a query request to a virtual desktop management server, wherein the query request is used to request the virtual desktop management server to send current status information of a second virtual machine to a first virtual machine; the virtual desktop management server stores current status information of at least one virtual machine;

[0103] In this step, a virtual desktop management client can be installed on the first virtual machine. The virtual desktop management client can realize functions such as status viewing, instant messaging, file transfer, voice call, screen sharing, remote guidance, etc. between virtual machine users.

[0104] After the virtual desktop management client establishes a connection with the virtual desktop management server, communication and other related functions can be realized.

[0105] Exemplarily, the virtual desktop management tool in the embodiment of the present disclosure can be regarded as QQ software, the virtual desktop management client is QQ downloaded and installed on each desktop, and the virtual desktop management server is the Tencent computer room, which is responsible for the corresponding virtual desktop management client.

[0106] It should be noted that there is a one-to-one binding relationship between the virtual desktop management clients installed on the virtual machines, and the status information of the local virtual machines can be displayed.

[0107] The current status information includes the virtual machine running status, connection status, current user status and the receiving end status of the current virtual machine; wherein,

[0108] The operating status includes booting, suspended, shutting down or unknown;

[0109] The connection status includes: connecting, not connected or unknown;

[0110] The user status includes: logged in, offline, unknown, busy or busy;

[0111] The receiving end status includes: connection status, device type or physical location, etc.

[0112] Step 102: receiving the current status information of the second virtual machine obtained by the virtual desktop management server according to the query request;

[0113] For example, when user A (first user) queries the status of user B (second user), the user (first user) sends a query request to the virtual desktop management server, and the virtual desktop management server responds to the request and sends the status of user B (second user) to user A (first user).

[0114] Step 103: Send a data transmission request to the virtual desktop management server, where the data transmission request is used to request the virtual desktop management server to send a target transmission path to the first virtual machine;

[0115] Step 104: obtaining a target transmission path returned by the virtual desktop management server according to the data transmission request;

[0116] In this step, when the virtual desktop management server receives a data transmission request sent by the first virtual machine, the virtual desktop management server selects the optimal transmission path as the target transmission path according to the locations of the first virtual machine and the second virtual machine, and sends the target transmission path to the first virtual machine.

[0117] Specifically, the virtual desktop management server can obtain the specific location from the management server, and of course the most optimal transmission route can be obtained. For example, knowing the location from A to B, the transmission speed of multiple messages can be tested, and the fastest one can be selected and recorded as the optimal transmission path, and this path can be used when transferring files.

[0118] Step 305: Send target data to the second virtual machine according to the current state information of the second virtual machine and the target transmission path.

[0119] In this step, when performing file transfer or other communication operations, the virtual desktop management server selects the optimal transmission path for file transfer according to the locations of the two virtual machines.

[0120] In one embodiment, Figure 2 As shown, sending the target data to the second virtual machine according to the current state information of the second virtual machine and the target transmission path includes:

[0121] Step 1051: If the user status in the current status information of the second virtual machine is offline, the target transmission path and the target data are sent to the virtual desktop management server;

[0122] Step 1052: instruct the virtual desktop management server to receive the target data and the target transmission path, and monitor whether the user status in the current status information of the second virtual machine is online;

[0123] In one embodiment, instructing the virtual desktop management server to receive the target data and the target transmission receiving path, and monitoring whether the user status in the current status information of the second virtual machine is online includes:

[0124] Instructing the virtual desktop management server to receive the target data and store the target data in an offline file storage area in a file storage server of the virtual desktop management server;

[0125] Instructing the virtual desktop management server to determine whether the user status in the current status information of the second virtual machine is an online state;

[0126] If the user status in the current status information of the second virtual machine is an online state, and the virtual desktop management server receives a request for obtaining target data sent by the second virtual machine, at least the virtual desktop management server sends the target data to the second virtual machine according to the target transmission path, including:

[0127] If it is monitored that the user status in the current status information of the second virtual machine is an online state, instruct the virtual desktop management server to detect whether a request for obtaining the target data sent by the second virtual machine is received;

[0128] If the virtual desktop management server receives the request sent by the second virtual machine to obtain the target data, the virtual desktop management server is instructed to send the target data to the second virtual machine according to the target transmission path.

[0129] In this embodiment, after the virtual desktop management server receives the file, it actually stores the file in the file storage server of the virtual desktop management server. The file storage server includes two parts: an offline file storage area and a general file storage area. In terms of process, when a user sends information or a file to an offline address, the information and the file will be saved in this offline file storage area. The application for distribution will be made after the receiving user comes online. Specifically, the user can query the offline data once after coming online. If there is data to be received, the application for distribution can be made directly.

[0130] It should be noted that the offline file storage area is used to store offline files. Files are not saved indefinitely, but only data within a certain period of time (this time can be set, such as 30 days). Therefore, when storing offline files, time tags are required. The general file storage area is used to store sent or received files, similar to DingTalk. Users can download sent or received files within a limited time range.

[0131] Step 1053: If it is monitored that the user status in the current status information of the second virtual machine is online, and the virtual desktop management server receives a request for obtaining target data sent by the second virtual machine, instruct the virtual desktop management server to send the target data to the second virtual machine according to the target transmission path.

[0132] In this embodiment, when the receiving end virtual machine (second virtual machine) is offline, the virtual desktop management server receives the file, and then receives the file through application after the receiving end virtual machine (second virtual machine) comes online.

[0133] In one embodiment, before instructing the virtual desktop management server to receive the target data and the target transmission path and determining whether the user status in the current status information of the second virtual machine is an online state, the method further includes:

[0134] Instructing the virtual desktop management server to set a tag for the target data, wherein the tag carries user information;

[0135] Instructing the virtual desktop management server to receive the target data and the target transmission path, and determining whether the user status in the current status information of the second virtual machine is an online state includes:

[0136] If the user status in the current status information of the second virtual machine is an offline state, instruct the virtual desktop management server to determine whether the target user is online in the third virtual machine according to the user information carried in the tag;

[0137] If the virtual desktop management server determines that the target user is online on the third virtual machine according to the user information carried in the tag, the virtual desktop management server is instructed to send the target data to the third virtual machine.

[0138] In this embodiment, a label is added to the offline data, which contains user information. That is to say, if the user logs in on a different virtual machine (the third virtual machine), the application can also be received. As for the file storage server, it can be located on the management server, on a cluster, or on cluster servers distributed at corresponding locations (there may be more data interactions based on the same location).

[0139] Optionally, before sending the query request to the virtual desktop management server, the method further includes:

[0140] Send current status information to the virtual desktop management server in real time or at a scheduled time;

[0141] The virtual desktop management server is instructed to integrate the current status information of each virtual machine to form an information list.

[0142] In this embodiment, the virtual desktop management server may integrate the above status information for unified management and display through the UI of the virtual desktop management client side.

[0143] In one embodiment, sending the current status information to the virtual desktop management server in real time or periodically includes:

[0144] Sending JSON data to the virtual desktop management server, wherein the JSON data carries the current status information of the corresponding virtual machine;

[0145] The instructing the virtual desktop management server to integrate the current status information of each virtual machine to form an information list includes:

[0146] Instruct the virtual desktop management server to receive the JSON data, store the JSON data in a database, and update the data in the database.

[0147] In this embodiment, a json data can be used to briefly explain which user is currently connected to the virtual machine, the R terminal status, etc. This json data is sent to the virtual desktop management server and can be stored in the database, updated in real time according to the newly received data, and when this information needs to be queried, the latest information is also queried in real time from the database; and the data from the virtual machine to the virtual desktop management server can be implemented in a similar way to the heartbeat connection, such as sending a packet every 10 seconds. If it is not refreshed, the flag parameter is 0, and if it is refreshed, the flag parameter is 1, and the refreshed content is included; if the virtual machine is offline, the virtual desktop management server does not receive the information within a certain period of time (the setting itself is that the virtual machine sends the information to the virtual desktop management server through the virtual desktop management client), it is determined that the virtual machine is offline or unresponsive.

[0148] The data transmission method provided by the embodiment of the present disclosure can select the optimal path for file transfer between two virtual machines through the virtual desktop management server. In addition, the selection of the optimal path is more convenient than the prior art because the virtual desktop management server is located on the management server. When the management server directly uses the existing proxy server in the prior art, since the proxy server itself can obtain the location information of all virtual machines registered thereon, in this case, it is also very convenient for the virtual desktop management server to obtain the location information of each virtual machine. In addition, the method for determining the optimal path of the present disclosure is designed in consideration of the characteristics of the VDI system itself.

[0149] It should be noted that the virtual machine in the embodiment of the present disclosure refers to the cloud desktop management server responsible for managing all cloud desktops and users.

[0150] Specifically, if the two virtual machines are on the same server, there is no need to go through the network, and an internal data exchange can be performed based on the location of the data; if the two virtual machines are not on the same server, the virtual machines directly transmit data based on the peer information obtained from the virtual desktop management server.

[0151] Figure 3 A flowchart of a data transmission method provided by an embodiment of the present disclosure. Figure 3 As shown, the method is applied to a virtual desktop management server, and includes:

[0152] Step 301: Obtain a query request sent by a first virtual machine, wherein the query request is used to request a virtual desktop management server to send current status information of a second virtual machine to the first virtual machine; the virtual desktop management server stores current status information of at least one virtual machine;

[0153] Step 302: Send the current state information of the second virtual machine to the first virtual machine according to the query request;

[0154] Step 303: Obtain a data transmission request sent by the first virtual machine, where the data transmission request is used to request the virtual desktop management server to send a target transmission path to the first virtual machine;
