Abstract

A system and method for better bandwidth utilization in a network system, comprising a proxy, a server and a client. The proxy receives a data stream from the server, splits it into multiple data streams and transmits them to the client. The clients merges the multiple data streams into one stream. Multiple embodiments for both multicast and unicast streams are disclosed.

Claims

1. A network system comprising:

a plurality of computers;

a first one of the computers acting as an intermediary node in a transmission of a data stream from a second computer to a third computer;

said first computer having;

(a) means for receiving said data stream;

(b) means for splitting said data stream into a plurality of data streams;

(c) means for transmitting said plurality of data streams to said third computer;

and said third computer having;

(a) means for receiving said plurality of data streams;

(b) means for merging said plurality of data streams into one data stream.

2. The system of claim 1 wherein said first computer and said third computer communicate over IP protocol and at least two streams of said plurality of data streams have different IP route preferences.

3. The system of claim 1 wherein said first computer further contains means for adding informational redundancy into said plurality of data streams.

4. The system of claim 1 wherein User Datagram Protocol (UDP) is used for transmission of said plurality of data streams.

5. The system of claim 1 wherein Real Time Transmission Protocol (RTP) is used for transmission of said plurality of data streams.

6. The system of claim 1 wherein Transmission Control Protocol (TCP) is used for transmission of said plurality of data streams.

7. The system of claim 1 wherein at least one stream of said plurality of data streams has priority different from the priority of others of the plurality of data streams.

8. The system of claim 1, wherein multicast is used for transmission of said plurality of data streams.

9. The system of claim 8, wherein said third computer is enabled to dynamically change its subscription to at least one of the multicast groups, receiving said plurality of data streams.

10. The system of claim 1, further comprising a fourth computer and means for transmitting the merged data stream from said third computer to said fourth computer.

11. A method for improved bandwidth utilization in a network system providing a plurality of computers wherein a first one of the computers acts as an intermediary node in a transmission of a data stream from a second one of the computers to a third one of the computers, the method comprising the steps of:

(a) sending a data stream from a second one of said computers;

(b) receiving said data stream in said first one of said computers;

(c) splitting said data stream into a plurality of data streams in said first one of said computers;

(d) transmitting said plurality of data streams from said first one of said computers to said third one of said computers;

(e) receiving said plurality of data streams in said third one of said computers; and

(f) merging said plurality of data streams into one data stream in said third one of said computers.

12. The method of claim 11 wherein said first one of said computers actively creates a separate connection to said third one of said computers for every one of said plurality of data streams.

13. The method of claim 11 wherein said third one of said computers actively creates multiple connections to said first one of said computers in order to accommodate the plurality of data streams.

14. The method of claim 11 further comprising the steps of providing a fourth one of said computers and transmitting the data stream from said third one of said computers to said fourth one of said computers.

15. The method of claim 11 further comprising the step of enabling said third one of said computers to merge the plurality of data streams into one data stream.

16. The method of claim 11 further comprising the step of adding informational redundancy into said plurality of data streams.

17. The method of claim 11 wherein said first one of said computers and said third one of said computers communicate over IP protocol and at least two of the streams of said plurality of data streams have different IP route preferences.

18. The method of claim 11, wherein said plurality of data streams is transmitted using User Datagram Protocol (UDP).

19. The method of claim 11 wherein said plurality of data streams is transmitted using Real Time Transmission Protocol (RTP).

20. The method of claim 11 wherein said plurality of data streams is transmitted using Transmission Control Protocol (TCP).

21. The system of claim 11 wherein at least one stream of said plurality of data streams has a priority different from the priority of the remainder of said plurality of data streams.

22. The method of claim 11 wherein at least one of the data streams of said plurality of data streams is multicasted.

23. The method of claim 22 further comprising the step of dynamically changing a subscription to at least one of the multicast groups for receiving said plurality of data streams in the third one of said computers.
