The present invention is directed to methods and computer program products for communicating real time data streams between a plurality of virtual meeting attendees over a digital data network. One exemplary method of the invention includes the steps of receiving a plurality of real time data streams from each of a plurality of virtual meeting attendees, of linking a first and a second of the real time data streams from each of the attendees to a first network interface, of linking only the first data stream from each of the attendees to a second network interface, and of linking only the second data stream from each of the attendees to a third network interface.

4. A method as defined by claim 2 wherein the step of recording said usage includes recording the amount of data consumed by said requestor.

5. A method as defined by claim 1 wherein said first real time data stream is audio data and said second real time data stream is video data.

6. A method as defined by claim 1 wherein said plurality of real time data streams further includes a third real time data stream, and further including the step of linking said third real time data stream from each of said plurality of virtual meeting attendees to a third network interface.

7. A method as defined by claim 6 wherein said plurality of real time data streams includes a total of n streams, and further including the step of linking each of said n streams from each of said virtual meeting attendees to one of n network interfaces, where n is any positive integer.

8. A method as defined by claim 7 wherein said first real time data stream from said n streams is video data, wherein said second real time data stream from said n streams is audio data, wherein said third real time data stream from said n streams is application data, and wherein a fourth real time data stream from said n streams is auxiliary data.

9. A method as defined by claim 1 wherein said first and second network interfaces are within a bridge.

10. A method as defined by claim 1 wherein said first and second interfaces are each one port.

11. A method as defined by claim 1 wherein said first and second interfaces are each a plurality of ports.

12. A method as defined by claim 1 wherein each of said plurality of real time data streams are encoded in a packet based protocol that includes a discrete control portion and a discrete data portion, wherein said first network interface includes a first port linked to said first real time data stream data portion to and a second port linked to said first real time data stream control portion to, and wherein said second interface includes a first port linked to said second real time data stream data portion to and a second port linked to said second real time data stream control portion to

13. A method as defined by claim 1 wherein said plurality of virtual meeting attendees are a first plurality of virtual meeting attendees at a first virtual meeting, and wherein the method further includes the steps of:

receiving a second plurality of real time data streams from each of a second plurality of attendees of a second virtual meeting, said second plurality of real time data streams from each of said second plurality of virtual meeting attendees including a first and a second real time data stream;

linking only said first real time data stream from said second plurality of data streams from each of said second plurality of second virtual meeting attendees to a third network interface; and

,

linking only said second real time data stream from each of said second plurality of second virtual meeting attendees to a fourth network interface.

14. A method as defined by claim 13 wherein said first real time data streams from each of said first plurality of first virtual meeting attendees and said first real time data streams from each of said second plurality of second virtual meeting attendees are video data streams, and wherein said second real time data streams from each of said first plurality of first virtual meeting attendees and said second real time data streams from each of said second plurality of second virtual meeting attendees are audio data streams.

15. A method as defined by claim 1 wherein said plurality of virtual meeting attendees are physically present in a plurality of conference rooms, each of said conference rooms having a plurality of cameras for communicating a plurality of real time video streams.

16. A method as defined by claim 1 and further including the step of designating at least one of said first and second network interfaces as a high bandwidth interface, and of connecting the highest bandwidth data stream from said plurality of real time data streams to said high bandwidth interface.

17. A method as defined by claim 1 wherein at least one of said first and second network interfaces is an interface between unicast and multicast communications.

18. A method as defined by claim 1 and further including the preliminary step of querying each of said plurality of virtual meeting attendees to identify said first and second real time data streams.

19. A method for linking data communications between a plurality of users in a virtual meeting on a data network, the method comprising the steps of:

designating a first network interface for communicating real time video data streams;

designating a second network interface for communicating real time audio data streams;

querying the plurality of users to determine what types of real time data streams each of said plurality of users will communicate to and from the network, said types of data including at least video and audio data; and

,

linking each individual of said plurality of users to one or both of said first and second network interfaces depending on what types of data said each individual of said plurality of users selected.

20. A method as defined by claim 19 and further including the steps of recording the usage by each of said users of each of said first, second, third or fourth network interfaces.

21. A method as defined by claim 20 wherein the step of recording said usage includes recording the duration time that each of said users is linked to each of said first, second, third or fourth interfaces, and further including the step of multiplying said duration time by a respective per-unit time fee for said interface to calculate a fee for each of said plurality of users.

24. A computer program product for linking data communications between a plurality of users in each of a plurality of virtual meetings on a data network, the program product comprising computer executable instructions stored on a computer readable medium that when executed cause one or more computers to:

A computer program product as defined by claim 24 wherein the program instructions further cause the one or more computers to assign an identifier to each of said first, second, third and fourth interfaces, said identifier having inherent knowledge that describes the content of the data streams linked thereto.

26. A computer program product as defined by claim 24 wherein the program instructions further cause the one or more computers to assign identifiers to each of said network interfaces, said identifier for said first network interface including A and X, said identifier for said network second interface including A and Y, said identifier for said third network interface including B and X, and said identifier for said fourth network interface including B and Y, where A is an identifier for said first virtual meeting, B is an identifier for said second virtual meeting, X is an identifier for an interface having only video data, and Y is an identifier for an interface having only audio data.
