Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a web virtualization system according to an embodiment of the present invention.

Examples of the client 100 are an Internet access device such as a personal computer, a laptop computer, a personal digital assistant (PDA), a cellular telephone, a mainframe computer, a mini computer and a Web TV.

Further, the client 100 preferably is equipped with web browser software such as MICROSOFT INTERNET EXPLORER, MOZILLAFIREFOX, etc. and is connected to the network 300 using any known data communication networking technology.

In a desktop virtualization environment, a remote desktop client may correspond to the client 100. [ The host computer 200 is a server for establishing a virtual environment and providing the virtual environment to the client 100. It is possible to efficiently operate various applications of different guest OS 210 such as Windows and Linux on one system physically.

The client 100 is equipped with a web browser 101, and the web browser 101 is responsible for distinguishing between the Internet and a PC. Historically, the function of the early browser was poor, so it only received and displayed data from the Internet, and encryption and video playback were impossible. We have developed a plug-in to extend the functionality of these browsers. A plug-in is an extension program that is installed to solve an operation that can not be handled by the application itself. Active X, developed by Microsoft Corporation, is a plug-in for web browsers. It is used to use contents downloaded from WWW by applying Component Object Model and Object Linking (OLE). While plug-ins allow access to the system, the problem is that if a website becomes heavy and an Internet program can touch a PC through a web browser, the security measures become ineffective.

The web browser 101 according to the present invention preferably supports the HTML5 standard. Recently, the W3C has changed the web application 1.0 standard to the HTML5 standard, and the HTML5 standard has become the official standard. In HTML5, all kinds of work such as internet banking, e-government, video streaming, web hard, game can be processed by all web browsers without installing plug-in, and user's convenience can be achieved.

Accordingly, in the HTML5 environment according to an embodiment of the present invention, it is not necessary to install a plug-in such as a separate Active X or security program in the Web browser 101 of the client 100, .

The host computer 200 includes a hypervisor, one or more guest virtual machines (not shown) and a guest OS 210, and provides web services to the client 100.

A hypervisor is a logical platform for simultaneously executing a plurality of operating systems in the host computer 200 and is a kind of middleware between the central processing unit and the OS. It is also called a virtual machine monitor (VMM for short).

Guest virtual machine " refers to a computer logically created by software on a real host computer 200 for an individual guest user. Such as a central processing unit (CPU), an input / output device (I / O), and the like, and it is possible to connect a plurality of users' clients 100 on one computer to operate a plurality of systems. Guest OS 210 is an operating system running on the guest virtual machine and may be any operating system such as CP / M, MS-DOS, Windows, Unix, Linux, VMS, OS /

It also includes a system API (Application Program Interface), which is a set of subroutines or functions that can be called when an application or web application that is an individual application program running on the guest OS 210 needs to use the basic functions of the system .

A web application refers to an application that provides services through a connection between users in a web environment connected to the Internet. When a service is requested using the address bar of the web browser of the client 100, the hyper link, or the submit button, the request information is processed and sent to the web browser 101 of the client 100 in HTML5 format. 1, the listener 211 and the web socket 212 are shown.

A listener 211 is a special type of web application that is automatically executed while monitoring a specific event occurring on the guest OS 210. The client 100 is executed upon connection to the host computer 200 so that the client 100 can exchange communication with the web socket 212. [

A Web Socket 212 enables full-duplex communication between the Web browser and the Web server. Since the Web socket 212 can solve the disadvantage of the XML Http Request, the XML Http Request, which is a core technology of the existing Ajax (Asynchronous Java Script + XML), is a means for receiving a data transmission request from the browser side to the server, It is difficult to push data to the client browser. This makes it difficult to support Ajax applications that frequently exchange data between the server and the client. In addition, the Comet technology allows for push from the server side, but resets the TCP handshaking whenever communication is needed for bidirectional communication However, the web socket 212 can perform all necessary communication based on a web socket dedicated protocol on the connection after the server and the client once connect to each other using HTTP. The connection time can be maintained for a long time, and the communication loss is small because a lightweight protocol is used unlike HTTP. Also, since all data can be sent and received through one connection, it is less influenced by other applications connected to the same server.

The communication network 300 refers to a connection means capable of providing a connection between the client 100 and the host computer 200. A wide area network (WAN), a local area network (LAN), an intranet, a Code Division Multiple Access (CDMA), a Wideband Code Division Multiple Access (WCDMA) , Global System for Mobile Communications (GSM), and Long Term Evolution (LTE), or any type of network to be implemented in the future regardless of its name.

2 is a diagram illustrating a virtual desktop access page according to an embodiment of the present invention.

When the client 100 accesses the virtual desktop environment of the host computer 200, the listener 211 is executed and the environment setting page shown in Fig. 2 is displayed on the client 100. [ Select the configuration menu, write the VDI server IP and port, select the connection test menu to confirm normal operation, and then save the configuration.

After setting up the environment, enter the user ID and password from the login menu and use the web service in the virtual desktop environment.

Unlike the conventional method in which a virtualization client program is installed for a virtualization service and then connected to the virtualization service, a virtual environment can be used by directly logging in the web browser 101 of the client 100 without installing a virtualization client program Give.

3 is a view illustrating a virtual desktop screen transmitted to a web browser according to an exemplary embodiment of the present invention.

Referring to FIG. 3, a screen value executed in a virtual desktop environment is transmitted as a screen value to a virtualization area, which is a part of the web browser 101.

FIG. 4 is a diagram illustrating a web virtualization service method according to an embodiment of the present invention.

When the Web browser 101 of the client 100 attempts to access the host computer 200 in step S401, the listener 211 is driven to display the environment setting page of FIG. 2 on the Web browser 101, And requests socket information to the web socket 212 (S403).

The web socket 212 delivers the socket information to the listener 211 (S405), and the listener 211 returns the socket information to the web browser 101 (S407).

The web browser 101 writes an ID and a password in accordance with the received socket information and logs in and tries to access the web socket 212 in step S409 and the web socket 212 sends the login information to the guest OS 210 .

The guest OS 210 returns the connection result to the web socket 212 (S413), and the web socket 212 delivers the connection result to the web browser 101 (S415).

In the case of normal login and connection, a command for web service is transmitted (S417, S419) in a virtualized environment through the web browser 101, data is returned through the guest OS 210, and the web service is provided S421, and S423).

4, steps S401 to S421 are sequentially executed. However, this is merely an exemplary description of the technical idea of the present embodiment, and it will be understood by those skilled in the art that, It is to be understood that various changes and modifications may be made by practicing the method of the present invention by changing the order described in FIG. 5 or by executing at least one of steps S401 to S421 in parallel without departing from the essential characteristics. But is not limited thereto.
