Cloud desktop, also known as desktop virtualization, cloud computers, is a typical application in the cloud computing era. The cloud desktop performs virtualization processing on various physical devices by using a virtualization technology, so that the utilization rate of resources is effectively improved, and in practice, after the cloud desktop is adopted, components such as a CPU (Central Processing Unit, a central processing unit), a memory, a hard disk and the like contained in a host can be virtualized in a server at the rear end. In a use scenario of cloud desktops, users typically implement a shared desktop through third party software. However, the third party software cannot be guaranteed in terms of convenience and safety of use.
Next, embodiments of the present specification will be described in detail.
As shown in fig. 1, fig. 1 is a flowchart of a desktop sharing method according to an exemplary embodiment, where the method is applied to a target cloud desktop client, and the method includes:
step 101, after a cloud desktop is successfully logged in, a sharing request is sent to the cloud desktop server, so that the cloud desktop server authenticates the sharing request;
the cloud desktop architecture generally comprises a cloud desktop server, a cloud desktop client and other components, wherein the cloud desktop server is deployed on a server, and an administrator can perform configuration management on cloud desktop business through the cloud desktop server; the cloud desktop client is a client program connected with the cloud desktop and deployed on user equipment, and a user can access a virtual machine host on a server through the cloud desktop client to realize interactive operation.
The target cloud desktop client in this embodiment is a cloud desktop client corresponding to an initiator of desktop sharing, and the device where the cloud desktop client is located may be any one of a PC (Personal Computer ), a thin terminal, and the like. After the cloud desktop client is installed, the device can log in the cloud desktop through the cloud desktop client, specifically, a user can input information such as an account number and a password in a login interface displayed by the cloud desktop client, and if the input information is legal, the user can successfully log in the cloud desktop to enter a cloud desktop system for use. The legal information can be information acquired during user registration, and the information can be pre-stored in the cloud desktop client by the user, so that the cloud desktop client can automatically log in the cloud desktop by using the information after being started.
When a user initiates a shared desktop, the target cloud desktop client may send a sharing request to the cloud desktop server, and the cloud desktop server may authenticate the sharing request, thereby determining whether the sharing request is sent by a legitimate user. In some examples, when the target cloud desktop client successfully logs in the cloud desktop, the target cloud desktop client may acquire credentials for authentication issued by the cloud desktop server. The credential may be a Token (Token) that serves as an identification of the target cloud desktop client during desktop sharing. The credential may be a string of characters randomly generated by the cloud desktop server, or may be generated by the cloud desktop server according to at least one of information such as an account number, a device number, a Mac address of a device, a login time, and the like of the cloud desktop client. The specific credential generation manner may also be selected according to requirements of a specific service scenario, which is not described herein. In this way, the credentials may be carried in the sharing request sent by the target cloud desktop client, so that the cloud desktop server may authenticate the sharing request according to the credentials.
To reduce the probability of cracking the credential by an illegitimate user, in some examples, the credential is time-efficient, that is, the credential has a life cycle, that is, a valid time, during which the target cloud desktop client may use the credential to send a request related to the desktop sharing service to the cloud desktop server, and if the valid time is exceeded, the credential fails. Accordingly, when the certificate meets the preset failure condition, the target cloud desktop client in the embodiment can request a new certificate to the cloud desktop server, so that the certificate is dynamically refreshed. Whether the certificate meets the preset invalidation condition can be judged according to the remaining effective time of the certificate, for example, the preset invalidation condition can be that the ratio of the remaining effective time of the certificate to the total effective time is smaller than or equal to a preset ratio, taking the effective time of the certificate as an example, if the preset ratio is 25%, when the remaining effective time of the certificate is smaller than or equal to 15 minutes, the certificate is considered to meet the preset invalidation condition; or, the preset failure condition may be that the remaining valid time of the certificate is less than or equal to the preset remaining time, and also taking the valid time of the certificate as an example, if the preset remaining time is 20 minutes, when the remaining valid time of the certificate is less than or equal to 20 minutes, the certificate is considered to satisfy the preset failure condition. Of course, in other embodiments, the preset failure condition may also be set according to the requirements of a specific scenario, which is not limited in this specification. Therefore, as each certificate is kept valid only in a certain time, the cracking difficulty of illegal users is increased, the information security is improved to a certain extent, and for legal users, before the certificate is invalid, the cloud desktop client can acquire new certificates in time, thereby ensuring the usability of the certificates and not affecting normal use.
In addition, on one side of the cloud desktop server, after issuing the certificate, the cloud desktop server can store the information of the certificate to a designated position, such as a designated list, so that when a sharing request of a target cloud desktop client is received, the cloud desktop server can match the certificate carried in the sharing request with the information recorded in the designated list, and if the matching is successful, the authentication is determined to be successful. Of course, in the case where the credentials are time-efficient, the cloud desktop server may delete the information of the expired credentials from the specified list.
102, establishing connection based on a specified protocol with the cloud desktop server;
because the target cloud desktop client is a sharing request sent to the cloud desktop server under the condition of successfully logging in the cloud desktop, when the cloud desktop server receives the sharing request, the user corresponding to the target cloud desktop client can be determined to belong to a legal user, so that authentication success is determined.
In this embodiment, when authentication is successful, the target cloud desktop client may use a specific protocol to establish a connection with the cloud desktop server, where the specific protocol may be a specific cloud desktop protocol, and is a set of rules for specifying how to exchange "control information" and "data information" between the cloud desktop server and the cloud desktop client. That is, after establishing the connection based on the specified protocol, the cloud desktop client may transmit the desktop data to the cloud desktop server based on the specified protocol, and the cloud desktop server may also transmit the desktop data to the cloud desktop client based on the specified protocol. Accordingly, the connection may be considered a specific connection dedicated to transmitting desktop data and other related information. Because connection based on the specified protocol can be realized on the basis of successful authentication, and the condition that the cloud desktop client successfully logs in the cloud desktop is required to be satisfied, the scheme of the embodiment actually opens the cloud desktop protocol and the account system of the public cloud, thereby realizing rapid and convenient sharing of the cloud desktop.
Step 103, acquiring cloud desktop instances distributed by the cloud desktop server, and transmitting desktop data to the cloud desktop instances through the connection, so that the cloud desktop server distributes the desktop data to other cloud desktop clients.
The cloud desktop instance mentioned in the step can be a storage resource allocated by the cloud desktop server according to the sharing request of the cloud desktop client, and the storage resource can be obtained by abstracting and displaying a storage hardware resource on the server. The cloud desktop instance runs on a server to provide a virtual cloud desktop session, and each cloud desktop client connected to the cloud desktop instance is actually connected to the same virtual cloud desktop session, that is, desktop data can be transferred between a cloud desktop server and each cloud desktop client connected to the cloud desktop instance through the cloud desktop instance, and the desktop data can comprise at least one of data such as documents, videos, audios, images, keyboard and mouse inputs, other peripheral inputs and the like. Specifically, after the target cloud desktop client obtains the cloud desktop instance, the desktop data can be transferred to the cloud desktop instance, so that the cloud desktop server can distribute the desktop data to other cloud desktop clients connected with the cloud desktop instance except the target cloud desktop client through the cloud desktop instance. It should be noted that, the manner in which other cloud desktop clients join the virtual cloud desktop session may be to accept the invitation of the target cloud desktop client, or may be to select from a cloud desktop instance list provided by the cloud desktop server, or may also be to search a session number corresponding to the cloud desktop instance, and so on. The specific adding mode can be adjusted according to the requirements of the service scene, and the specification is not limited to the specific adding mode.
According to the scheme, after the target cloud desktop client successfully logs in the cloud desktop, a sharing request is sent to the cloud desktop server so that the cloud desktop server can authenticate, when authentication is successful, connection based on a specified protocol is established between the target cloud desktop client and the cloud desktop server, and cloud desktop instances distributed by the cloud desktop server are obtained, so that desktop sharing is achieved. Therefore, the appointed protocol and the cloud desktop account system are communicated, so that the whole process does not need complicated setting, the method is more convenient and quick, and the method has higher safety.
In some embodiments, after obtaining the cloud desktop instance allocated by the cloud desktop server, the target cloud desktop client may further include: and sending a control instruction to the cloud desktop server, wherein the control instruction is used for controlling the running state of the cloud desktop instance. Specifically, the cloud desktop server may include a component for controlling the cloud desktop instance, where the component may execute a corresponding control operation according to a control instruction sent by the target cloud desktop client. The running state of the cloud desktop instance may include a state of starting, suspending, stopping, etc. of the cloud desktop instance, may also include a user state of connecting to the cloud desktop instance, or may also include a related state of desktop data in the cloud desktop instance, etc. That is, the cloud desktop client that initiated the sharing request, i.e., the sharer, may have control over the cloud desktop instance, e.g., before starting sharing, the sharer may invite a specified user to connect to the cloud desktop instance to make the specified user a sharee; after the shared desktop data is ready, the sharer can control to start sharing so that the sharee can acquire the shared desktop data; at the end, the sharer may control the sharing to be turned off so that the sharee cannot continue to acquire the desktop data of the sharer. Therefore, the initiator sharing the desktop can have a certain dominant right, and the convenience in use is better ensured.
Further, in some embodiments, the aforementioned control instructions may include instructions to control input sources of cloud desktop instances, including input sources provided by a target cloud desktop client, and input sources provided by other cloud desktop clients connected to the cloud desktop instance other than the target cloud desktop client. Specifically, the sharer may selectively open whether to allow the sharee to provide an input source according to a setting of the sharee, where the input source may include at least one of various peripherals such as a keyboard, a mouse, and a headset. For example, in a meeting, a conference moderator may act as a sharer to share desktop data with other users logged into the same virtual cloud desktop meeting, and during the meeting, the sharer may control a designated one of the other users to be turned on to provide keyboard and mouse input to select and/or edit the shared desktop data by the designated user. Therefore, richer application scenes are facilitated to be realized, and in an ideal state, the participants sharing the desktop can have experience as if the participants are all in front of the same computer.
In addition, in some scenes, the number of participants sharing the desktop is large, and resources required to be consumed by the cloud desktop server side when the traffic forwarding is realized are correspondingly large. Accordingly, some embodiments of the present description provide the following improvements: the cloud desktop client connected to the cloud desktop instance comprises a first cloud desktop client, and after receiving desktop data distributed by the cloud desktop server, the first cloud desktop client can transmit the desktop data to a second cloud desktop client which is under the same local area network as the first cloud desktop client in a multicast mode. The first cloud desktop client may include a target cloud desktop client, that is, for a scenario in which the sharer and a part of the sharees are in the same local area network, the part of the sharees may directly receive desktop data transmitted by the sharer in a multicast manner, without being pulled from a server; the first cloud desktop client may also include other cloud desktop clients, that is, for a scenario in which at least two sharees are in the same local area network, one sharee may pull desktop data from a server, and then the sharee may transmit the desktop data to other sharees under the local area network in a multicast manner. Therefore, the transmission of desktop data is realized by utilizing the multicasting of the two-layer network, and the traffic of the public network is saved.
Further, in some examples, the aforementioned specified protocol may be used to pass desktop data from a target cloud desktop client to other cloud desktop clients connected to the cloud desktop instance in addition to the target cloud desktop client. That is, after the cloud desktop client initiating the sharing request transmits the desktop data to the cloud desktop server through the specified protocol, the cloud desktop server may also transmit the desktop data to other cloud desktop clients through the specified protocol. Accordingly, the connection between the cloud desktop server and other cloud desktop clients based on the specified protocol may be established if authentication of the other cloud desktop clients is successful. Because the whole sharing process is realized based on the appointed protocol, the sharees cannot directly touch the data of the sharers, thereby ensuring the information security of the sharers.
As shown in fig. 2, fig. 2 is a flowchart of another desktop sharing method according to an exemplary embodiment of the present disclosure, where the method is applied to a cloud desktop server, and the method includes:
step 201, after a target cloud desktop client successfully logs in a cloud desktop, receiving a sharing request sent by the target cloud desktop client, and authenticating the sharing request;
step 202, establishing connection based on a specified protocol with the target cloud desktop client;
step 203, a cloud desktop instance is allocated to the target cloud desktop client, and when the target cloud desktop client transmits desktop data to the cloud desktop instance through the connection, the desktop data is distributed to other cloud desktop clients.
As shown in fig. 3, fig. 3 is a schematic diagram of a desktop sharing system according to an exemplary embodiment of the present disclosure, where the system includes a cloud desktop server 31 and a cloud desktop client 32; in this embodiment, the cloud desktop client 321 is a target cloud desktop client, and the cloud desktop client 322 is another cloud desktop client except the target cloud desktop client; wherein:
the cloud desktop server 31 is configured to receive a sharing request sent by the cloud desktop client 321 after the cloud desktop client 321 successfully logs in a cloud desktop, and authenticate the sharing request; establishing a connection based on a specified protocol with the cloud desktop client 321; distributing cloud desktop instances to the cloud desktop client 321, and distributing desktop data to the cloud desktop client 322 when the cloud desktop client 321 transmits the desktop data to the cloud desktop instances through the connection;
the cloud desktop client 321 is configured to send a sharing request to the cloud desktop server 31, and transmit desktop data of a device currently located to a cloud desktop instance allocated by the cloud desktop server 31; the cloud desktop client 322 is configured to obtain the desktop data through the cloud desktop instance.
The embodiments shown in fig. 2 and fig. 3 correspond to the previous embodiments shown in fig. 1, and thus, the implementation process of each step in the embodiment of fig. 2 and the implementation process of the functions and roles of each unit in the embodiment of fig. 3 may refer to the implementation process of the corresponding step in the embodiment of fig. 1, which is not repeated herein.
For a more detailed description of the desktop sharing scheme of the present disclosure, a specific embodiment is described below:
