Abstract

A method for establishing a dedicated session for a member of a common frame buffer group includes the step of transmitting, by a server agent, via at least one frame buffer channel, a first frame buffer update to each generated by one of the plurality of associated clients. The method includes the step of detecting an event generated by one of the plurality of associated clients. The method includes the step of removing, by the server agent, the one of the plurality of associated clients, from the plurality of associated clients. The method includes the step of establishing, by the server agent, a second frame buffer channel between the removed one of the plurality of associated clients and the server agent. The method includes the step of transmitting a second frame buffer update, by the server agent, to the removed one of the plurality of associated clients via the second frame buffer channel.

Claims

1. A method for establishing a dedicated session for a member of a common frame buffer group, the method comprising the steps of:

(a) transmitting, by a server agent, via at least one frame buffer channel, a first frame buffer update of frame buffer updates to each of a plurality of associated clients of a common frame buffer group receiving the frame buffer updates from a shared application executing on the server;

(b) detecting an event representative of a user interaction via one of a click or keyword input to the shared application and generated by one of the plurality of associated clients, wherein the event triggers generation of a second frame buffer update;

(c) removing, by the server agent responsive to detection of the event, the one of the plurality of associated clients from the plurality of associated clients of the common frame buffer group receiving frame buffer updates from the at least one frame buffer by resetting an attribute of the one of the plurality of associated clients to block the one of the plurality of associated clients from receiving frame buffer updates transmitted to the common frame buffer group via the at least one frame buffer channel;

(d) establishing, by the server agent responsive to detection of the event, a new second frame buffer channel between the removed one of the plurality of associated clients and the server agent by addressing one of a unique internet protocol (IP) address or device identifier of the removed one of the plurality of associated clients, the second frame buffer channel providing a dedicated session between the removed one of the plurality of associated clients and the shared application; and

(e) transmitting, by the server agent, to the removed one of the plurality of associated clients, via the second frame buffer channel, the second frame buffer update that provides an update from the shared application to only the one of the plurality of associated clients based on the user interaction of the one of the plurality of associated clients.

2. The method of claim 1 further comprising the steps of:

(f) adding, the removed one of the plurality of associated clients, to the plurality of associated clients; and

(g) transmitting a third frame buffer update to the plurality of associated clients via the at least one frame buffer channel.

3. The method of claim 1, wherein step (a) further comprises multicasting, by a server agent, via at least one frame buffer channel, a first frame buffer update to each of a plurality of associated clients.

4. The method of claim 1, wherein step (a) further comprises transmitting, by the server agent, via a plurality of frame buffer channels, the first frame buffer update to each of the plurality of associated clients, each of the plurality of frame buffer channels established between one of the plurality of associated clients and the server agent.

5. The method of claim 1 further comprising the step of transmitting, by the server agent, to each of the plurality of associated clients, via the at least one frame buffer channel, a frame buffer update representative of a paging event.

6. The method of claim 5, wherein step (b) further comprises detecting a first event comprising a response to the paging event.

7. The method of claim 1, wherein step (c) further comprises removing an Internet protocol address associated with the removed one of the plurality of associated clients from a multicast Internet protocol address.

8. The method of claim 1 further comprising the step of receiving, by the server agent, a frame buffer update generated by an application in communication with the server agent, the frame buffer update representative of output data generated by the application.

9. The method of claim 1 further comprising the step of modifying a frame panel associated with each of the plurality of associated clients, responsive to the detection of the event.

10. The method of claim 9 further comprising the step of generating the second frame buffer update representative of the modified frame panel.

11. The method of claim 1 further comprising the step of generating, by an application in communication with the server agent, the second frame buffer update, responsive to the detected event.

12. The method of claim 1 further comprising the step of receiving, by the server agent, an event representative of user interaction with one of the plurality of associated clients.

13. The method of claim 1, further comprising the steps of:

(f) executing, by each of the plurality of associated clients, a frame buffer client;

(g) generating a display with the frame buffer client; and

(h) updating the display, responsive to receiving, from the server agent, a frame buffer update.

14. The method of claim 1 further comprising the step of transmitting, by the server agent, to an application, an event generated by a client in the plurality of associated clients via a frame buffer channel between the server agent and the application.

15. A system for establishing a dedicated session for a member of a common frame buffer group comprising:

a processor;

a server agent executing on the processor to perform;

establishing at least one frame buffer channel with each of a plurality of associated clients of a common frame buffer group receiving frame buffer updates from a shared application executing on the server;

transmitting via the at least one frame buffer channel, a first frame buffer update of the frame buffer updates to each of the plurality of associated clients of the common frame buffer group receiving the frame buffer updates from the shared application executing on the server;

detecting an event representative of a user interaction via one of a click or keyword input to the shared application and generated by one of the plurality of associated clients, wherein the event triggers generation of a second frame buffer update;

removing, responsive to detection of the event, the one of the plurality of associated clients from the plurality of associated clients of the common frame buffer group receiving frame buffer updates from the at least one frame buffer by resetting an attribute of the one of the plurality of associated clients to block the one of the plurality of associated clients from receiving frame buffer updates transmitted to the common frame buffer group via the at least one frame buffer channel;

establishing, responsive to detection of the event, with the removed one of the plurality of associated clients, a new second frame buffer channel, addressing one of a unique internet protocol (IP) address or device identifier of the removed one of the plurality of associated clients, the second frame buffer channel providing a dedicated session between the removed one of the plurality of associated clients and the shared application; and

transmitting, via the second frame buffer channel, the second frame buffer update providing a frame buffer update from the shared application to only the one of the plurality of associated clients based on the user interaction of the one of the plurality of associated clients.

16. The system of claim 15, wherein the server agent executes on an application gateway.

17. The system of claim 15, wherein the server agent executes on a server.
