Abstract

Certain embodiments of the present invention provide for a system and method for preserving bandwidth in data networks. The method includes determining whether to perform functional redundancy processing for a current data set. Determining whether to perform functional redundancy processing for a current data set may be conducted according to redundancy rules. In performing functional redundancy processing, the method includes receiving a first data set and a second data set and storing the first data set in a queue. The method may also include determining whether the content of the first data set is functionally redundant to the content of said second data set. If the contents of the first data set are functionally redundant to the contents of the second data set, the method includes transmitting the first data set and dropping the second data set. Functionally redundant messages are dropped prior to transmission, optimizing bandwidth.

Claims

1. A method for controlling the quality of service for data communication, the method comprising:

receiving a first data set and a second data set;

storing said first data set in a queue;

determining whether the content of said first data set is functionally redundant to the content of said second data set; and

,

transmitting said first data set and dropping said second data set if the contents of said first data set are functionally redundant to the contents of said second data set.

2. The method of claim 1, further including, prior to determining whether the content of the first data set is functionally redundant to the content of said second data set, determining whether to perform functional redundancy processing for said second data set based on redundancy rules, said redundancy rules being controlled by a selected mode.

3. The method of claim 2, wherein said selected mode is selected by a user.

4. The method of claim 2, wherein said selected mode is selected dynamically based on network conditions.

5. The method of claim 2, wherein said redundancy rules determine whether to perform functional redundancy processing based on information contained in the header of data in the second data set.

6. The method of claim 2, wherein said redundancy rules determine whether to perform functional redundancy processing based on information contained in the payload of the second data set

7. The method of claim 2, wherein said redundancy rules determine whether to perform functional redundancy processing based on the source node of the second data set.

8. The method of claim 1, wherein said step of determining whether the content of the first data set is functionally redundant to the content of said second data set further includes searching said queue for said first data set and comparing the contents of said first data set with the contents of said second data set based on said redundancy rules.

9. The method of claim 1, wherein said second data set is received later in time than said first data set.

10. A computer-readable medium having a set of instructions for execution on a processing device, said set of instructions comprising:

a receiving routine for receiving a first data set and a second data set;

a storing routine for storing said first data set in a queue;

a redundancy routine for determining whether the content of said first data set is functionally redundant to the content of said second data set; and

,

a transmitting routine for transmitting said first data set and dropping said second data set if the contents of said first data set are functionally redundant to the contents of said second data set.

11. The set of instructions of claim 10, further including, prior to the redundancy routine, a determining routine for determining whether to perform functional redundancy processing for said second data set based on redundancy rules, said redundancy rules being controlled by a selected mode.

12. The set of instructions of claim 11, wherein said selected mode is selected by a user.

13. The set of instructions of claim 11, wherein said selected mode is selected dynamically based on network conditions.

14. The set of instructions of claim 11, wherein said redundancy rules determine whether to perform functional redundancy processing based on information contained in the header of data in the second data set.

15. The set of instructions of claim 11, wherein said redundancy rules determine whether to perform functional redundancy processing based on information contained in the payload of the second data set

16. The set of instructions of claim 11, wherein said redundancy rules determine whether to perform functional redundancy processing based on the source node of the second data set.

17. The set of instructions of claim 10, wherein said redundancy routine further includes a searching routine for searching said queue for said first data set and comparing the contents of said first data set with the contents of said second data set based on said redundancy rules.

18. A method for data communication, the method comprising:

receiving a first data set;

storing said first data set in a queue;

receiving a second data set;

determining whether to perform functional redundancy processing for said second data set based on redundancy rules, said redundancy rules being controlled by a selected mode;

searching said queue for said first data set and determining whether said first data set is functionally redundant to said second data set based on said redundancy rules; and

,

if said first data set is functionally redundant to said second data set, dropping said second data set.

19. The method of claim 18, wherein said redundancy rules determine that the first data set is functionally redundant to said second data set by comparing the content of the first data set and the content of the second data set.

20. The method of claim 19, wherein said content of said first data set and the content of said second data set includes audio content.
