FIG. 2 shows a block diagram of a computing device 200, according to one embodiment of the invention. It should be noted that the computing device 200 shown in fig. 2 is only an example, and in practice, the computing device for implementing the switching method of the virtual desktop display protocol of the present invention may be any type of device, and the hardware configuration thereof may be the same as that of the computing device 200 shown in fig. 2 or different from that of the computing device 200 shown in fig. 2. In practice, the computing device for implementing the switching method of the virtual desktop display protocol according to the present invention may add or delete hardware components of the computing device 200 shown in fig. 2, and the present invention does not limit the specific hardware configuration of the computing device.
As shown in FIG. 2, in a basic configuration 202, a computing device 200 typically includes a system memory 206 and one or more processors 204. A memory bus 208 may be used for communication between the processor 204 and the system memory 206.
Depending on the desired configuration, the processor 204 may be any type of processing, including but not limited to: a microprocessor (μ P), a microcontroller (μ C), a digital information processor (DSP), or any combination thereof. The processor 204 may include one or more levels of cache, such as a level one cache 210 and a level two cache 212, a processor core 214, and registers 216. Example processor cores 214 may include Arithmetic Logic Units (ALUs), Floating Point Units (FPUs), digital signal processing cores (DSP cores), or any combination thereof. The example memory controller 218 may be used with the processor 204, or in some implementations the memory controller 218 may be an internal part of the processor 204.
Depending on the desired configuration, system memory 206 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. The physical memory in the computing device is usually referred to as a volatile memory RAM, and data in the disk needs to be loaded into the physical memory to be read by the processor 204. System memory 206 may include an operating system 220, one or more applications 222, and program data 224. In some implementations, the application 222 can be arranged to execute instructions on the operating system with the program data 224 by the one or more processors 204.

It will be appreciated by those skilled in the art that the application 222 may include other applications 226 for implementing other functions in addition to instructions for performing the switching method 300 of the virtual desktop display protocol.
FIG. 3 illustrates a flow diagram of a method 300 for switching virtual desktop display protocols, the method 300 being suitable for execution in a computing device (e.g., the computing device 200 shown in FIG. 3), according to one embodiment of the invention.
The computing device stores an association table of usage scenarios and display protocols of applications. The display protocols comprise rdp protocol, spice protocol and vnc protocol, and the use scenario of the application and the association table of the display protocols can be obtained by a theoretical analysis method. For example, the rdp display protocol cannot display the BIOS screen, but it performs well in terms of color, audio, and usb transmissions, whereas users are working with office software, which involves much interaction with small data volumes, and the user's screen content typically varies little. Therefore, when a user uses the office software for office work, it is more appropriate to use the rdp display protocol, and the office scene of the office application can be associated with the rdp display protocol. Of course, in order to ensure the accuracy of the obtained usage scenario and display protocol association table of the application, after obtaining the usage scenario and display protocol association table of the application through theoretical analysis, the usage scenario and display protocol association table of the application may be further revised through experimental tests. The present invention is not limited in particular to the method for obtaining the association table of the usage scenario and the display protocol of the application.
In addition, it is explained here that, since there are a plurality of usage scenarios for some applications and the display protocol suitable for each usage scenario is different, the present invention stores the association table of the usage scenarios and the display protocols of the applications. For example, the love art audio and video software has two use scenes. When a user browses on the interface of the Aiqiyi audio-visual software, the browsing scene of the Aiqiyi application is used, the protocol is suitable for rdp display, and when the user watches videos on the Aiqiyi audio-visual software, the watching scene of the Aiqiyi application is used, and the protocol is suitable for spice display. Therefore, the invention associates the browsing scene of the Aichi art application with the rdp display protocol and associates the viewing scene of the Aichi art application with the spice display protocol.
As shown in fig. 3, the method 300 for switching the virtual desktop display protocol starts at step S310. In step S310, load data of an application corresponding to the current virtual desktop and load data of the server side are obtained based on the trigger condition. The load data of the application comprises data which can represent the process characteristics of the application, such as the CPU utilization rate, the memory utilization rate, the network utilization rate, the disk utilization rate, the number of file handles held by the process of the application and the like of the process of the application. The server-side load data includes, but is not limited to, CPU usage, memory usage, network usage, and disk usage of the system.
According to an embodiment of the present invention, the trigger condition may be that a variation value of the load data on the server side at a certain time is larger than a first predetermined value. The method comprises the steps of monitoring load data of a server side in real time, and acquiring the load data of an application corresponding to a current virtual desktop and the load data of the server when a change value of the load data of the server side at a certain moment is larger than a first preset value. And acquiring the load data of the application corresponding to the current virtual desktop and the load data of the server as long as the change value of any load data at the server side at a certain moment is greater than a first preset value. For example, if the network usage rate of the server side at a certain time is suddenly increased compared to the previous time, and the change value is greater than the first predetermined value, the load data of the application corresponding to the current virtual desktop and the load data of the server are obtained. The value of the first predetermined value is not particularly limited. In the specific embodiment, a person skilled in the art can set the setting according to actual needs.
For convenience, the trigger condition may be set to a predetermined time, that is, the load data corresponding to the current virtual desktop and the load data on the server side may be acquired once every predetermined time. The triggering condition may be set by a person skilled in the art according to actual needs, and the present invention is not limited to this.
It should be noted that, the virtual desktop can be displayed on the client device, which shows that a corresponding application program is running on the server side. Thus, each virtual desktop necessarily corresponds to an application, and the current virtual desktop corresponds to the application to which the current active window corresponds.
And then, the process goes to step S320, and the trained scene recognition model is used to recognize the usage scene of the application according to the load data of the application and the load data of the server side. The scene recognition model may adopt a decision tree model. When the decision tree model is adopted, a training sample set is obtained firstly, each sample in the training sample set is load data of an application and load data of a server side, and a label of the sample is a use scene of the application. And then, training a decision tree by using the acquired sample set to obtain a trained scene recognition model. According to an embodiment of the present invention, the load data of the application includes a CPU usage rate, a memory usage rate, a network usage rate, a disk usage rate of the process of the application, and the number of file handles held by the process of the application, and the load data of the server side includes a CPU usage rate, a memory usage rate, a network usage rate, and a disk usage rate of the system. It should be noted that other models may be used as the scene recognition model, and the present invention is not limited in this respect.
The generation of the scene recognition model file is described below with a specific example. Scenario a of a known application is first run on a development machine. Then, the load data of the development machine (i.e., the load data of the system) and the load data of the application are collected, and the collected result is recorded to the file a. And analogizing in sequence, collecting system load data and application load data under various application scenes on a development machine, and sequentially recording the system load data and the application load data to the files B, C and D. Finally, the load data files (A, B, C, D,...) under various scenes of various applications are trained into model files, namely scene recognition model files (namely scene recognition models), through a development library related to a machine learning decision tree.
Obviously, after the trained scene recognition model is obtained, the obtained load data of the application corresponding to the current virtual desktop and the obtained load data of the server side are input into the trained scene recognition model, so that the use scene of the application corresponding to the current virtual desktop can be obtained. As an example, assuming that the current virtual desktop displays a frame of a video being played by the aitchicraft software, that is, the user is currently watching the video using the aitchicraft software, the load data of the aitchicraft software playing the video (i.e., the load data of the current active window) and the load data of the system loading the video at that time (i.e., the load data of the server at that time) are input into the trained scene recognition model, so that the watching scene currently used by the aitchicraft application can be recognized.
And then, the step S330 is carried out, and the display protocol matched with the current virtual desktop is determined according to the application use scene and the association table. After the use scene of the application is obtained, the display protocol associated with the use scene of the application can be obtained by comparing the use scene with the stored association table, that is, the display protocol associated with the use scene of the application corresponding to the current virtual desktop is obtained, so that the display protocol is the display protocol matched with the current virtual desktop.
And then, step S340 is performed, and the actual display protocol is switched according to the determined display protocol matched with the current virtual desktop and the actual display protocol of the current virtual desktop. Specifically, whether the determined display protocol matched with the current virtual desktop is consistent with the actual display protocol of the current virtual desktop is judged. And when the determined display protocol matched with the current virtual desktop is inconsistent with the actual display protocol of the current virtual desktop, switching the actual display protocol of the current virtual desktop into the display protocol matched with the current virtual desktop.
In order to prevent the display protocol from being jammed during switching and affecting the user experience, according to an embodiment of the present invention, the actual display protocol of the current virtual desktop may be switched to the display protocol matching the current virtual desktop based on the device lock mechanism.
Specifically, when desktop display protocols such as rdp, spice, vnc and the like are analyzed on the client side, the desktop display protocols are uniformly analyzed into standard local device instructions which can be displayed by the display device, then the device instructions obtained through analysis are pressed into a cache queue, and locking and unlocking are set for pressing and popping of the cache queue.
When the determined display protocol matched with the current virtual desktop is inconsistent with the actual display protocol of the current virtual desktop, locking the client side (which can be considered as locking the cache queue) first, and monitoring the cache queue on the client side for storing the display protocol decoded content (i.e. the content decoded by the display protocol). Then, when the buffer queue is empty, the actual display protocol of the current virtual desktop is switched to the display protocol matched with the current virtual desktop, and the client is unlocked (it can be considered as unlocking the buffer queue).
Therefore, when the display protocol is determined to be switched, the display device is locked firstly. And then, switching the display protocol when the buffer queue is empty. And finally, unlocking the display equipment after the display protocol is switched. The switching of the display protocol is completed through the three steps, so that the smooth transition of the display protocol can be realized, and the consistency of the display picture of the client is ensured.
When the determined display protocol matched with the current virtual desktop is consistent with the actual display protocol of the current virtual desktop, the display protocol of the current virtual desktop is not adjusted, and the actual display protocol of the current virtual desktop is continuously used.
In addition, it is described herein that the switching method of the virtual desktop display protocol according to the present invention can be executed on both the client side and the server side. When the virtual desktop is operated on the client side, the load data of the application corresponding to the current virtual desktop and the load data of the server side are sent to the client side by the server. And when the display protocol switching is determined to be performed, the client side sends a protocol switching instruction to the server side, namely, the client and the server both switch the currently used display protocol to the display protocol matched with the current virtual desktop. The transmission of the load data and the protocol switching instruction is carried out in a self-established private network channel of the server and the client, and the channel and the display protocol channel are not interfered with each other. Similarly, when the client side operates on the server side and determines to switch the display protocol according to the load data, the server side also sends a protocol switching instruction to the client side, so that the client side and the server both switch the currently used display protocol to the display protocol matched with the current virtual desktop.
Fig. 4 shows a block diagram of a switching apparatus 400 for a virtual desktop display protocol according to an embodiment of the present invention, which is suitable for residing in a computing device 200, wherein an association table of a display protocol and a usage scenario of an application is stored in the computing device. As shown in fig. 4, the switching apparatus 400 of the virtual desktop display protocol includes an obtaining module 410, an identifying module 420, a determining module 430, and a switching module 440.
The obtaining module 410 is adapted to obtain load data of an application corresponding to the current virtual desktop and load data of the server side based on the trigger condition.
And the recognition module 420 is adapted to recognize the usage scenario of the application by using the trained scenario recognition model according to the load data of the application and the load data of the server side.
And the determining module 430 is adapted to determine a display protocol matched with the current virtual desktop according to the application use scene and the association table.
The switching module 440 is adapted to switch the actual display protocol according to the determined display protocol matched with the current virtual desktop and the actual display protocol of the current virtual desktop.
The details of the switching device 400 for the virtual desktop display protocol according to the present invention are disclosed in detail in the description based on fig. 1 and fig. 3, and are not described herein again.
According to the switching method of the virtual desktop display protocol, firstly, based on the trigger condition, the load data of the application corresponding to the current virtual desktop and the load data of the server side are obtained. And then, according to the load data of the application and the load data of the server side, using the trained scene recognition model to recognize the use scene of the application. And finally, determining a display protocol matched with the current virtual desktop according to the application use scene and the association table. And when the determined display protocol matched with the current virtual desktop is inconsistent with the actual display protocol of the current virtual desktop, switching the actual display protocol of the current virtual desktop into the display protocol matched with the current virtual desktop. Therefore, when a user accesses a virtual machine in a server through terminal equipment or a personal PC to display a virtual desktop, the method and the system can identify the use scene of the current desktop (namely the scene of the currently used application) in real time based on the load data of the application corresponding to the virtual desktop and the load data of the server side, and provide a display protocol which is most matched with the currently used application scene for the user. Obviously, the switching method of the virtual desktop display protocol can give full play to the efficiency of various display protocols, thereby improving the experience of users and reducing the consumption of bandwidth resources.
In addition, the display protocol is switched based on the equipment locking mechanism, and the actual display protocol of the current virtual desktop is switched to the display protocol matched with the current virtual desktop only when the buffer queue is empty, so that the continuity of the display picture of the client can be ensured, and the user experience is further improved.
