Description

[0001] The present invention relates to a virtualization client capable of controlling multiple screens in a virtual operating system environment,

The present invention relates to a virtualization client capable of multi-screen control in a virtual operating system environment, and more particularly, to a virtualization client that uses a plurality of virtual operating systems to allocate a plurality of display devices for different operating systems, And controlling the command to be transmitted to an operating system used in a selected one of the plurality of display apparatuses.

PCs, which are a necessity for the enterprise, are not only costly to initialize, but also costly to manage software upgrades, security patches and hardware maintenance. For businesses, PCs have become a top priority for business efficiency and cost savings. In addition, the security problem that the important information is leaked by the hacking after the staff has stored the important data in the PC is also a big problem.

To address this, PC virtualization (or desktop virtualization) has been proposed. Desktop virtualization is a type of server based computing (SBC) that allows users to connect to a virtual desktop virtual machine in a data center server using a local device such as a thin client to access data, Technology. In other words, virtualization technology is used to build dozens of computers (desktops) on one central server, and users can connect to servers by using only terminals and peripherals to support their work as if they are using personal PCs. In a desktop virtualization system, a virtual desktop environment is created by combining a personalized user environment setting, an operating system, and an application according to a user's request, and the image is provided to the user through a browser.

In the desktop virtualization environment, the power consumption of the terminal is lower than that of the existing desktop environment, and various costs such as the software cost to be installed for each PC can be reduced, so that it is efficient in maintenance and management. Can be avoided.

Meanwhile, as a client for desktop virtualization (hereinafter referred to as a "virtualization client"), in addition to a thin client that greatly simplifies the function of a PC, all essential elements such as a hard disk are also removed, And the PC is used as a zero client which performs only the role of a terminal connecting the server.

Meanwhile, a virtualization apparatus has been proposed in which a plurality of display devices are connected to one virtualization client or a plurality of operating systems are connected and used. FIG. 1 is a block diagram illustrating an example of such a conventional system for desktop virtualization.

A plurality of virtualization clients 10 are connected to the virtualization server 20 through a network. A plurality of virtual operating systems may be operated in the virtualization server 20 for each virtualization client 10. Many virtual operating systems may be different operating systems, such as Windows and Mac OS, or they may have different security settings for the same operating system. For example, the first operating system may be a Windows operating system having a security level capable of accessing an intranet, and the second operating system may be a Windows operating system having a security level that can access the Internet but can not access the in-house network. By virtualizing and operating an operating system having a different security level, it is possible to prevent a virus program infiltrating from the Internet from hacking information in the internal network.

The virtualization client 10 may be connected to one or more display devices. 1 shows an embodiment in which two display devices 31 and 32 are connected to a virtualization client 10. [ The virtualization client 10 may also be connected to one or more input devices 41, 42 such as a keyboard, a mouse, a touchpad, and the like. In addition, a sound device 50 such as a microphone, a speaker, etc. for inputting and outputting sound can also be connected to the virtualization client 10. Depending on the embodiment, it may not support the connection of the audio equipment 50.

2 is a conceptual diagram illustrating a method of supporting a plurality of operating systems in a conventional virtualization client.

2, the connection selection block 11 of the virtualization client 10 can simultaneously access a plurality of operating systems supported by the virtualization server 20, but only one of the operating systems selected from the connected operating systems can be connected to one or more display devices (31, 32). Also, the input devices 41, 42 and the sound device 50 operate on the selected operating system.

In order to select one of a plurality of operating systems in the conventional virtualization client 10, if a list of connected operating systems is displayed after clicking a separate function button, a desired operating system is selected. Then, the virtualization client 10 fetches the screen for the selected operating system from the virtualization server 20 and displays it on the display devices 31 and 32. [ In addition, the input devices 41 and 42 and the audio device 50 also operate on the selected operating system.

However, in a conventional desktop virtualization system supporting a plurality of operating systems, only one operating system can be displayed on the screen at the same time, which is inconvenient to use. Also, the procedure for selecting a desired operating system from among a plurality of operating systems is inconvenient, and it takes a long time to load a screen for the selected operating system.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a virtualization client capable of simultaneously displaying a plurality of operating system screens.

3 and 4 are conceptual diagrams for explaining a method of supporting a plurality of virtual operating systems in a virtualization client according to the present invention, in which a first connection is activated, and FIG. 4 is a diagram illustrating a state in which a second connection is activated It shows the state of the case.

In the present invention, screen data of each virtual operating system to which the virtualization client 100 is connected is stored in the frame buffers 130a, 130b, .., 130n. A frame buffer may be allocated to a virtual operating system that is not currently displayed on the display device. The display devices 31 and 32 display a screen of the designated virtual operating system, respectively. 3, a screen of the first virtual OS is displayed (indicated by a dashed line) on the first display device 31, and a screen of the second virtual OS is displayed on the second display device 32 (indicated by a dotted line) . Meanwhile, although FIG. 3 shows the connection of two display devices, more display devices may be connected.

The OS selection unit 120 determines which virtual operating system the commands input from the input devices 41 and 42 are to be delivered to. 3 shows that a first connection is activated and a command input from the input devices 41 and 42 is transferred to the first connection (indicated by a dashed line). 4, a second connection is activated and a command input from the input devices 41 and 42 is transmitted to the second connection (indicated by a dotted line). In addition, acoustical instrument 50 is also connected for active connection.

Hereinafter, a virtual operating system to which an input command is transmitted is referred to as an " active operating system ". You can use the keyboard or mouse to select the active operating system.

The multi-OS processing unit 110 transmits screen data of each virtual operating system stored in the frame buffers 130a, 130b, ..., 130n to a display device designated by the connection profile. In addition, input data such as a keyboard input and a mouse input input from the input device 41 42 are transferred to a virtual operating system (active operating system) determined by the OS selecting unit 120. FIG. 3 shows a state in which the first operating system is activated. In this case, the input data input from the input device 41 42 is transmitted to the virtualization server 20 through the connection with the first operating system (first connection) . The transmitted input is processed in the first operating system, and the processed screen is transmitted to the virtualization client 100 through the first connection, and the virtualization client 100 displays the processed screen on the first display device 31. According to an embodiment, the multi-OS processing unit 110 outputs the sound data received through the connection to the active operating system to the audio device port, and transmits the sound input through the audio device port to the virtualization server Lt; / RTI > The multi-OS processing unit 110 may also display an icon, character, or the like indicating an active operating system at a predetermined position on the screen in order to indicate that the display device displays the active operating system in the display device on which the active operating system is displayed.

On the other hand, if the user changes the active operating system using a keyboard or a mouse, then the input data input from the input device 41 42 is transmitted to the changed operating system. Procedures for changing the active operating system using a keyboard or mouse are described below.

Next, the internal configuration of the virtualization client according to an embodiment of the present invention will be described with reference to FIG. 5 is a block diagram illustrating an internal configuration of a virtualization client according to an embodiment of the present invention.

The virtualization client has a plurality of display ports for connecting a plurality of display devices and one or more input device ports for connecting one or more input devices. According to an embodiment of the present invention, a sound device port for connecting a sound device such as a speaker or a microphone may be further provided.

The virtualization server connection unit 140 accesses the virtualization server 20 according to the contents described in the connection profile 150 to receive a screen of the designated virtual operating system and transmits a command inputted by the user through the input devices 41, To the server (20).

The connection profile 150 may include information (e.g., an access protocol, a server IP address, an ID, a password, and the like) necessary for server connection for each virtual operating system to which the virtualization client 100 is connected, Information (eg, screen output port, output priority, keyboard shortcut, output resolution, default mouse position, etc.). That is, information for the first connection is stored in the first connection profile 150a, information for the second connection is stored in the second connection profile 150b, and information for the nth connection is stored in the nth connection profile 150n . When the user changes the display device allocation information for a specific connection, the changed information is stored in the corresponding connection profile.

Meanwhile, according to an exemplary embodiment of the present invention, not only the profile of the currently connected virtual operating system but also the profile of all accessible virtual operating systems may be stored. In addition, information related to the entire connection, for example, the default active operating system that is activated when the virtualization client 100 is initialized, and the virtualization client password when the virtualization client 100 itself is password-protected May be defined in the connection profile 150.

The virtualization server connection unit 140 stores the screen data received through each connection in the frame buffer 130. One frame buffer is provided for each connection. That is, the first frame buffer 130a is provided for the first connection, the second frame buffer 130b for the second connection, and the nth frame buffer 130n for the n-th connection. Also, a frame buffer may be provided for a virtual operating system that is not currently displayed on the display device. Each frame buffer stores screen data sent from the corresponding operating system, regardless of whether or not the virtual operating system to which the frame buffer is connected is activated.

The multi-OS processing unit 110 transmits screen data of each operating system stored in the frame buffers 130a, 130b, ..., 130n to a display device designated by the connection profile. For example, if the first display device is designated in the first connection profile, the multi-OS processing unit 110 outputs the screen data stored in the first frame buffer 130a to the first display device. In addition, the multi-OS processing unit 110 transfers input data such as a keyboard input and a mouse input input from the input device 41 42 to the active OS. Depending on the embodiment, sound data may also be received from each operating system, and the multi-OS processing unit 110 outputs the sound data received from the active operating system to the sound device 50.

The OS selection unit 120 selects an active OS. When the virtualization client 100 is initialized, the default active operating system defined in the connection profile is selected as the active operating system. Thereafter, the OS selecting unit 120 selects an active operating system according to the operation of the input devices 41 and 42 of the user. Some examples of how to select an active operating system are described below.

1. Selection using hot keys

In the connection profile 150, a shortcut key for selecting each connection is defined. For example, if Shift-Alt-1 is a shortcut key for selecting a first connection, Shift-Alt-2 is a shortcut key for selecting a second connection, if the user presses Shift-Alt-1 on the keyboard, the OS selection unit 120 ) Selects the virtual operating system of the first connection as the active operating system regardless of the current active operating system. Accordingly, the cursor and the mouse pointer are activated in the display device assigned to the first connection. When two or more display devices are allocated to one connection, the mouse pointer is activated in the display device corresponding to the basic mouse position defined in the connection profile for the connection. When a hot key for selecting a virtual operating system is pressed, the corresponding key operation is not transmitted to the virtualization server 20 but is used only for selecting a virtual operating system.

2. Select using the mouse (for horizontal monitor placement)

When a user places a display device (hereinafter, referred to as a monitor) horizontally, if the user moves the mouse to the left or the right beyond the horizontal range of the current monitor, the operating system displayed on the monitor of the moved location is the active operating system do. To this end, each connection profile stores information about the resolution of the monitor assigned to the connection. When the mouse is moved, the OS selection unit 120 determines whether the horizontal movement range of the mouse from the current mouse position deviates from the horizontal resolution boundary of the current monitor. If the horizontal movement range is out of the horizontal resolution boundary, As the active operating system. For example, if the mouse is moved to the left to go beyond the horizontal resolution boundaries of the current monitor, the operating system assigned to the monitor located on the left side of the current monitor is selected as the active operating system. Of course, if there is no monitor currently on the left side of the monitor, the current monitor will remain intact and the mouse pointer will stay at the left end of the current monitor.

3. Select using the mouse (for vertical positioning of the monitor)

Even when the user places the display device, that is, the monitor vertically, it operates in the same manner as in the case No. 2. In other words, if you move the mouse up or down beyond the vertical range of the current monitor, the operating system displayed on the moved monitor becomes the active operating system. The operation in the case of the vertical arrangement is the same as in the case of the horizontal arrangement, and thus a detailed description thereof will be omitted.

The present invention can also be applied to more complex monitor layouts. For example, even when a monitor is arranged vertically at the center and a monitor is arranged at the left and right of the central lower monitor, an active operating system can be selected by moving the mouse. The monitor arrangement can be defined in a connection profile or in a separate profile, and the OS selection unit 120 can select the active OS using the monitor arrangement information and the resolution information of each monitor.

3 to 5 illustrate the case where two or three display devices are used, the present invention is not limited to the specific number of display devices. It is also possible to configure the number of connections currently maintained to match the number of displays. Although a keyboard and a mouse have been described as input devices, various input devices such as a touch pad and a touch screen may be used. For example, in embodiments where each monitor includes a touch screen, an active operating system may be selected by touching the touch screen.
