Abstract

Systems and methods for a VoIP session controller product that combines high performance packet processing throughput with low cost, based on a design that dynamically moves packet processing between user space and kernel based on individual call parameters.

Claims

1. A method for dynamically routing, by a session controller associated with an operating system, the handling of a stream of data packets passed between a first network and a second network comprising:

(a) intercepting, by a session controller that connects a first network and a second network, a stream of data packets traveling from the first network to the second network;

(b) processing, by the session controller, the stream of data packets; and

(c) forwarding the stream of data packets to a specified destination.

2. The method of claim 1 wherein processing, by the session controller, the stream of data packets further comprises applying data packet recognition to detect a preselected data packet from the stream of data packets.

3. The method of claim 1 wherein dynamically changing the path of the stream of data packets through the operating system and at least one of a device driver comprises optimizing the path of the stream of data packets through use of a kernel of the operating system.

4. The method of claim 1, wherein dynamically changing the path of the stream of data packets through the operating system and at least one of a device driver comprises forwarding the stream of data packets to its final destination.

5. The method of claim 1, wherein dynamically changing the path of the stream of data packets through the operating system and at least one of a device driver comprises routing the stream of data packets to a processor for further processing.

6. The method of claim 1, wherein dynamically changing the path of the stream of data packets through the operating system and at least one of a device driver comprises discarding the stream of data packets.

7. The method of claim 1, further comprising forking the stream of data packets to two or more than specified destinations.

8. The method of claim 1, wherein the stream of data packets comprise audio signals.

9. A system for dynamically routing, by a session controller associated with an operating system, a stream of data packets passed from a first network to a second network comprising:

(a) a session controller connected to both a first network and a second network for intercepting a stream of data packets traveling from the first network to the second network; and

(b) a processor associated with the session controller and an operating system of the session controller, processing the stream of data packets;

(c) the session controller dynamically changing the path of the stream of data packets by the session controller through an operating system of the session controller and a device driver; and

(d) the session controller forwarding the stream of data packets to a specified destination.

10. The system of claim 9 wherein the session controller applies data packet recognition to detect a preselected data packet from the stream of data packets.

11. The system of claim 9 wherein a kernel of the operating system associated with the session controller and a device driver optimize the path of the stream of data packets.

12. The system of claim 9 wherein the specified destination includes a final destination,

13. The system of claim 9 wherein a processor associated with both the operating system and the session controlled further processes the stream of data packets.

14. The system of claim 9 wherein the session controller forwarding the stream of data packets to a specified destination comprises discarding the stream of data packets.

15. The system of claim 9 wherein the session controller forks the stream of data packets to two or more specified destinations.

16. The system of claim 9 wherein the stream of data packets comprise audio signals.

17. A method for routing a stream of data packets in a communications system, the method comprising:

(a) intercepting, by a kernel module of the session controller, a stream of data packets traveling from an origin to a predetermined destination;

(b) processing, by the kernel module of the session controller, the stream of data packets; and

(c) forwarding the stream of data packets to the predetermined destination upon completion of the processing.

18. The method of claim 17 further comprising forwarding a portion of the stream of data packets to an application executing on the session controller for processing by the application prior to forwarding the stream of data packets to the predetermined destination.

19. The method of claim 17 further comprising forwarding a portion of the stream of data packets to a hardware device in communication with the session controller for processing by the hardware device prior to forwarding the stream of data packets to the predetermined destination.

20. The method of claim 19 wherein the hardware device is a field programmable gate array.
