Abstract

A client-server-communication system comprises

• • a public network (1), especially the Internet,
  • a server computer (2)
    • running at least one server application which provides a graphical user interface,
    • wherein the server application creates basic GUI data to be processed by a graphics processing unit (7) for controlling said graphical user interface, which basic GUI data at least include a set of geometric basic primitives, and
  • a client computer (3)
    • including a graphics processing unit (7),
    • connectable to the server computer (2) via the public network (1), and
    • running a browser program (5) which is HTML5 capable,
    • in which browser program (5) a client-side-script-program (9) including a WebSocket protocol (10) is running, which receives and interprets the basic GUI data and from these basic GUI data renders drawing instructions as graphics content for being processed by the graphics processing unit (7) of the client computer (3).

Claims

1. A client-server-communication system comprising

a public network (1), especially the Internet,

a server computer (2)

running at least one server application which provides a graphical user interface,

wherein the server application creates basic GUI data to be processed by a graphics processing unit (7) for controlling said graphical user interface, which basic GUI data at least include a set of geometric basic primitives, and

a client computer (3)

including a graphics processing unit (7),

connectable to the server computer (2) via the public network (1), and

running a browser program (5) which is HTML5 capable,

in which browser program (5) a client-side-script-program (9) including a WebSocket protocol (10) is running, which receives and interprets the basic GUI data and from these basic GUI data renders drawing instructions as graphics content for being processed by the graphics processing unit (7) of the client computer (3).

2. A client-server-communication system according to claim 1, wherein the graphics content is passed to the browser program (5) with displaying server application data in a display area of the browser program (5).

3. A client-server-communication system according to claim 1, wherein the basic GUI data are at least one of Primitives, OpenGL/GDI and DirectX commands which if necessary are emulated by the client-side-script-program (9).

4. A client-server-communication system according to claim 1, wherein I/O channel (15) data are handled by the client-side-script-program (9).

5. A client-server-communication system according to claim 1, wherein the client-side-script-program (9) handles the data transfer including the basic GUI data (13) or I/O channel (15) data over the WebSocket protocol (10) in a compressed form, and in particular over a Special Remote Desktop Protocol (12).

6. A client-server-communication system according to claim 1, wherein the client-side-script-program (9) further on provides for one or more of following functionalities:

handling bitmaps data (14), especially compressed bitmaps data (14),

applying raster operations onto the basic GUI data (13),

obtaining drawing contexts and creating Canvas or WebGL elements (17) and updating same.

7. A client-server-communication system according to claim 1, comprising a gateway program (4) running on the server computer (2) or on a separate computer.

8. A client-server-communication system according to claim 7, wherein the gateway program (4) receives at least basic GUI data from the server computer (2).

9. A client-server-communication system according to claim 7, wherein the gateway program (4) provides for a decryption and decompression functionality (18) of data received from the server computer (2).

10. A client-server-communication system according to claim 7, wherein the gateway program (4) provides a splitter and filter operation functionality (19) selecting between different types of data stream channels, like basic GUI data (13), bitmaps (14) or I/O data (15) channels.

11. A client-server-communication system according to claim 7, wherein the gateway program (4) performs a Special Remote Desktop Protocol (12s).

12. A client-server-communication system according to claim 14 wherein the Special Remote Desktop Protocol (12s) is designed to transport the data streams of separated channels (13s, 14s, 15s) of GUI data, bitmaps or I/O data to the client computer (3) over a WebSocket protocol (10s, 10c) and a HTTP/HTTPS protocol (11s, 11c) over the public network (1).

13. A client-server-communication system according to claim 11, wherein the Special Remote Desktop Protocol (12s, 12c) is providing a flow control related to that protocol layer.

14. A client-server-communication system according to claim 10, wherein the gateway program (4) further performs a Special Remote Desktop Protocol (12s).
