There is this. As a result, there are a limited number of applications that can be executed on clients connected to the server, and it is impossible to use applications that require high resolution.

In addition, due to the limitation of the resolution that can be expressed in the client, the video cannot be represented properly, so the client has to be limited. In addition, the number of clients that can access a single server is limited to less than 20, the operating system also has the disadvantage that only Win2000.

Finally, the resource allocation system between server and client using RDP protocol cannot use client's peripherals (CD-ROM, FDD, printer, etc.). Has a fatal drawback of being down.

An object of the present invention is to implement the resource allocation of the server in hardware in the form of ENS card in order to improve the speed, the limitation of remote control and the limitation of the utilization of the application, which is a disadvantage of resource allocation by the conventional software method. .

Another object of the present invention is to provide a remote control function and a security function between a server and a client by using an ENS card for resource allocation.

Now, the resource allocation mechanism between the server 10 and the client 30 _i according to the present invention will be described. First, the client 30 _i transmits a resource allocation request signal to the socket module of the ENS card of the server 10 through the socket module of the ENS card 20 mounted on the client. When the client transmits such a resource allocation request signal to the server 10, the ENS stream, which is the driving engine of the resource allocation system of the present invention installed in the server, responds to the memory of the ENS card 20 mounted in the server 10. Through the file module of the controller 24, the resource allocation information previously designated to the server in the form of a database is transmitted to the client 30 _i .

In the existing software resource allocation system, the server generally transmits image data in response to a resource allocation request signal from a client. However, the transmission of such image data is slow because a large amount of information is transmitted to the client, and there is a fatal weakness that the resource allocation system itself is down when resource allocation information is concentrated on the server. .

However, in the resource allocation system through the ENS card of the present invention, in response to the resource allocation request signal from the client, the server 10 transmits information in a database format instead of an image format, thereby making it possible to reduce the load on the server. do. The data transmitted to the client 30 _i by such a database method is converted from the virtual CD back to the virtual image by the ENS card, so that the minimum amount of data is transferred between the server and the client according to the present invention. The speed drop, which is a problem of the system, is fundamentally prevented.

On the other hand, when a plurality of clients simultaneously request resource allocation information to the server, a problem may occur that the overall resource allocation speed is reduced due to a load on the server. However, the resource allocation system according to the present invention uses a thread module of the memory controller 24 of the ENS card 20 on the server 10 side when a plurality of clients request resource allocation information from the server. The plurality of clients requesting the resource allocation information are subdivided into a predetermined unit and timed to transmit the resource allocation information to the plurality of clients. Therefore, even if a plurality of clients request resource allocation information from the server, the problem of speed decrease does not occur.
