Abstract

A system and method for transmitting the same data to more than one client node or from an application to at least two client nodes. The method includes connecting a first client node and a first client protocol stack and connecting the application and the first client protocol stack; associating a first minimal communications protocol stack with the first client protocol stack; providing a connection between the application and the first minimal communications protocol stack and between a second client node and a second client protocol stack; associating a second minimal communications protocol stack with the second client protocol stack; providing a connection between the first minimal protocol stack and the second minimal protocol stack; and between the second minimal protocol stack and said the client protocol stack. Data is then transmitted from the application program to the first client protocol stack and the first minimal protocol stack substantially simultaneously.

Claims

1. A method for displaying application output on a client node, the method comprising:

providing, by a server to a browser application executing on a client node, a data file comprising remote application parameters and instructions for generating, by the browser application, a first window;

establishing a communication channel between a client process executing on the client node and the server;

executing an application on the server responsive to receiving a request from the client process, via the communication channel, the request comprising the remote application parameters; and

transmitting, via the communication channel, output produced by the application executing on the server to the client process for display in a second window on the client node, the second window generated by the client process as a child of the first window of the browser application.

2. The method of claim 1, wherein executing the application further comprises executing the application responsive to executing of a JAVA applet on the client node.

3. The method of claim 1, wherein executing the application further comprises executing the application responsive to input received from an HTML page displayed by the browser application.

4. The method of claim 3, wherein executing the application further comprises executing the application responsive to selecting a tag displayed in the HTML page.

5. The method of claim 1, wherein establishing a communication channel further comprises establishing a data pipe between the client process and the application executing on the server.

9. The method of claim 1, wherein transmitting output produced by the application executing on the server to the client process for display in a second window on the client node comprises transmitting output to the client process for display in the second window, the second window generated as a child of the first window responsive to the client process receiving a window handle of the first window from the browser application.

6. A system for displaying application output on a client node, the system comprising:

a server configured to;

provide a data file to a client node, the data file comprising remote application parameters and instructions for generating, by a browser application executed by the client node, a first window;

execute an application, responsive to receiving a request from a client process executed by the client node, the request comprising the remote application parameters, and the application generating application output; and

transmit the application output to the client process for display in a second window on the client node, the second window generated by the client process as a child of the first window of the browser application.

7. The system of claim 6 wherein the application executes on the server responsive to output generated by a page displayed within the browser application executing on the client node.

8. The system of claim 7, wherein the client process transmits the page output to the server.

10. A method for displaying application output on a client node, the method comprising:

receiving from a server, by a first client process comprising a browser application executing on a client node, a data file comprising remote application parameters and instructions for generating a first window;

generating, by the first client process, responsive to the received instructions, a first window comprising a first window handle;

executing, by the client node, responsive to the remote application parameters, a second client process;

receiving, by the second client process from the first client process, the remote application parameters and the first window handle; and

generating, by the second client process responsive to receiving the first window handle, a second window as a child of the first window.

11. The method of claim 10, wherein generating a second window as a child of the first window comprises generating the second window over the first window.

12. The method of claim 10, further comprising:

scrolling, by a graphical user interface of the client node, the second window, responsive to a user command to scroll the first window.

13. The method of claim 10, further comprising:

transmitting, by the second client process via a communications channel established between the second client process and the server, the remote application parameters;

receiving, by the second client process via the communications channel, application output of an application executed by the server responsive to receiving the remote application parameters; and

displaying, by the second client process, the received application output in the second window.

14. The method of claim 13, further comprising:

receiving, by the second client process, input from a user in the second window; and

transmitting, by the second client process via the communications channel, the received input to the application executed by the server.
