Abstract

Certain embodiments relate to systems and methods for managing congestion notification and control across a network. In certain aspects, a protocol for managing sender and receiver-based congestion control is provided using a format for streaming parameters, such as the Session Description Protocol format. In certain aspects, a system and method for operating an interworking gateway between different user devices is provided.

Claims

1. A communications device to control data congestion comprising:

a computer system configured to;

receive an session description protocol (SDP) offer, the offer specifying one of sender-driven or receiver-driven congestion control;

generate an SDP answer, the answer specifying one of sender-driven or receiver-driven congestion control; and

send the SDP answer, the SDP answer comprising a plurality of parameters, wherein one or more of the plurality of parameters indicates congestion control information.

2. The communications device of claim 1, wherein the SDP offer specifies receiver driven congestion control.

3. The communications device of claim 2, the computer system further configured to send media under receiver driven congestion control.

4. The communications device of claim 1, wherein the SDP offer specifies sender driven congestion control.

5. The communications device of claim 4, wherein the computer system is further configured to send media under sender driven congestion control.

6. The communications device of claim 1, wherein the communications device is capable of operating in sender-driven or receiver-driven congestion control.

7. The communications device of claim 1, wherein the computer system is further configured to determine a first congestion control for a first direction of flow and a second congestion control for a second direction control, the first congestion control different from the second congestion control.

8. The communications device of claim 1, wherein the congestion control information of the one or more of the plurality of parameters in the SDP answer indicates receiver-driven congestion control.

9. The communications device of claim 1, wherein the congestion control information of the one or more of the plurality of parameters in the SDP answer indicates sender-driven congestion control.

10. A method of controlling data congestion comprising:

receiving a session description protocol (SDP) offer, the offer specifying one of sender-driven or receiver-driven congestion control;

generating an SDP answer, the answer specifying one of sender-driven or receiver-driven congestion control; and

sending the SDP answer, the SDP answer comprising a plurality of parameters, wherein one or more of the plurality of parameters indicates congestion control information,

the method implemented on a communications device.

11. The method of claim 10, wherein the SDP offer specifies receiver driven congestion control.

12. The method of claim 11, further comprising sending media under receiver driven congestion control.

13. The method of claim 10, wherein the SDP offer specifies sender driven congestion control.

14. The method of claim 13, further comprising sending media under sender driven congestion control.

15. The method of claim 10, wherein the communications device is capable of operating in sender-driven or receiver-driven congestion control.

16. The method of claim 10, further comprising determining a first congestion control for a first direction of flow and a second congestion control for a second direction control, the first congestion control different from the second congestion control.

17. The method of claim 10, wherein the congestion control information of the one or more of the plurality of parameters in the SDP answer indicates receiver-driven congestion control.

18. The method of claim 10, wherein the congestion control information of the one or more of the plurality of parameters in the SDP answer indicates sender-driven congestion control.

19. A non-transitory computer-readable medium having stored thereon instructions configured to cause one or more computer systems in a device to control data congestion to:

receive a session description protocol (SDP) offer, the offer specifying one of sender-driven or receiver-driven congestion control;

generate an SDP answer, the answer specifying one of sender-driven or receiver-driven congestion control; and

send the SDP answer, the SDP answer comprising a plurality of parameters, wherein one or more of the plurality of parameters indicates congestion control information.

20. The non-transitory computer-readable medium of claim 19, wherein the SDP offer specifies receiver driven congestion control.

21. The non-transitory computer-readable medium of claim 19, wherein the SDP offer specifies sender driven congestion control.

22. The non-transitory computer-readable medium of claim 19, the instructions further causing the device to determine a first congestion control for a first direction of flow and a second congestion control for a second direction control, the first congestion control different from the second congestion control.

23. The non-transitory computer-readable medium of claim 19, wherein the congestion control information of the one or more of the plurality of parameters in the SDP answer indicates receiver-driven congestion control.

24. The non-transitory computer-readable medium of claim 19, wherein the congestion control information of the one or more of the plurality of parameters in the SDP answer indicates sender-driven congestion control.
