Abstract

An improved networked computer communications system handles arbitrary streams of data, and transports at varying speeds those streams where intermediate updates can be dropped if they are obsoleted by later arriving data updates, optimizing the utilization of network and node resources. Complex buffering by system server software allows distributed, parallel, or redundant processing, transmission, and storage for performance, reliability, and robustness. Various parameters of the system can be monitored, and the system can be reconfigured automatically based on the observations. Varied techniques reduce the perceived end-to-end latency and take advantage of software and hardware capabilities that assets connected to the system may possess. One conferencing system allows conference participants to share all or a portion of the display seen on their computer screens. The conferees may be at sites removed from each other, or may view a recorded presentation or archived conference at different times. Conference participants are either “presenters” who can modify the display or “attendees” who cannot modify the display. A pointer icon, which can be labeled to identify the conferee, is displayed on the shared image area Each conferee can modify the position of his or her own pointer, even when not presenting, so that every participant can see what each conferee is pointing to, should a conferee choose to point to an element of the display. These and other features apply to other data streams shared in the conference or in meetings where there is no shared-image data stream.

Claims

1. A conferencing system comprising:

a conference server;

at least one client the at least one client including a web browser; and

at least one network connection coupling the conference server and the at least one client, the conference server providing conferencing data to the at least one client via the at least one network connection after the client-server connection is established, the client-server connection established via the web browser at the at least one client having been navigated to a Universal Resource Locator associated with a conference, and wherein one or more characteristics of the provided conferencing data are based on current capabilities of the at least one client validated after establishing the client-server connection but prior to the at least one client joining the conference.

2. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises a size of at least part of the conferencing data.

3. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least some contents within the conferencing data.

4. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least some information about at least part of the conferencing data.

5. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least one source of at least part of the conferencing data.

6. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least one destination of at least part of the conferencing data.

7. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises a rate of reception of at least part of the conferencing data.

8. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises a rate of transmission of at least part of the conferencing data.

9. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises hardware involved in processing at least part of the conferencing data.

10. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises software involved in processing at least part of the conferencing data.

11. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least one protocol used in processing at least part of the conferencing data.

12. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least one modification to a conference environment originated by the server.

13. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises at least one modification to a conference environment originated by at least one client.

14. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises a quantity of reception of at least part of the conferencing data.

15. The conferencing system of claim 1, wherein one characteristic of the provided conferencing data comprises a quantity of transmission of at least part of the conferencing data.

16. The system of claim 1, wherein the at least one client is configured to negotiate with the conference server as to the current capabilities of the at least one client after establishing the client-server connection but prior to the at least one client joining the conference.

32. The system of claim 1, wherein the at least one client is configured to provide the conference server with a key prior to joining the conference, the key identifying one or more privileges of the at least one client during the conference.

33. The system of claim 32, wherein the one or more privileges includes entering the conference.

34. The system of claim 32, wherein the one or more privileges includes being a presented during the conference.

35. The system of claim 32, wherein the one or more privileges includes access to information about another attendee in the conference.

36. The system of claim 32, wherein the one or more privileges includes changing a conference setting.

17. A method for conferencing between a server and at least one client in a conferencing system, the method comprising:

establishing a network connection between the server and the at least one client, the network connection established via a web browser at the at least one client having been navigated to a Universal Resource Locator associated with a conference;

determining one or more characteristics of conferencing data for delivery during the conference, the determination based on current capabilities of the at least one client validated after establishing the client-server connection but prior to the at least one client joining the conference; and

providing the conferencing data from the server to the at least one client after establishing the network connection between the server and the at least one client and validating the current capabilities of the at least one client, the provided conference data based on the current capabilities of the at least one client.

18. The method of claim 17, wherein one characteristic comprises a size of at least part of the conferencing data.

19. The method of claim 17, wherein one characteristic comprises at least some contents within the conferencing data.

20. The method of claim 17, wherein one characteristic comprises at least some information about at least part of the conferencing data.

21. The method of claim 17, wherein one characteristic comprises at least one source of at least part of the conferencing data.

22. The method of claim 17, wherein one characteristic comprises at least one destination of at least part of the conferencing data.

23. The method of claim 17, wherein one characteristic comprises a rate of reception of at least part of the conferencing data.

24. The method of claim 17, wherein one characteristic comprises a rate of transmission of at least part of the conferencing data.

25. The method of claim 17, wherein one characteristic comprises hardware involved in processing at least part of the conferencing data.

26. The method of claim 17, wherein one characteristic comprises software involved in processing at least part of the conferencing data.

27. The method of claim 17, wherein one characteristic comprises at least one protocol used in processing at least part of the conferencing data.

28. The method of claim 17, wherein one characteristic comprises at least one modification to a conference environment originated by the server.

29. The method of claim 17, wherein one characteristic comprises at least one modification to a conference environment originated by at least one client.

30. The method of claim 17, wherein one characteristic comprises a quantity of reception of at least part of the conferencing data.

31. The method of claim 17, wherein one characteristic comprises a quantity of transmission of at least part of the conferencing data.
