Abstract

A system and method for a hybrid dynamic communication routing device is disclosed. The HDCR device monitors the condition of communication paths in a TDM network and in a packet based network. The HDCR adjusts a communication route between a first device and a second device based on the condition of the communication paths.

Claims (26)

1. A communication system comprising:

a time division multiplex (TDM) network having TDM communication paths between a first device and a second device;

a packet network having packet communication paths between the first device and the second device; and

wherein the TDM network and the packet network have hybrid communication paths through both the TDM network and the packet network between the first device and the second device;

a hybrid dynamic communication routing (HDCR) device configured to monitor a set of conditions for the TDM communication paths, the packet communication paths, and the hybrid communication paths, and configured to process communication path requirements and the set of conditions to select one of the TDM communication paths, the packet communication paths, and the TDM communication paths to transfer communications between the first device and the second device, wherein the set of conditions comprise TDM trunk occupancy and packet latency.

2. The communication system of claim 1 wherein the first device comprises a telephone.

3. The communication system of claim 1 wherein the second device comprises a gateway.

4. The communication system of claim 1 further comprising transferring the communications over the selected communication path between the first device and the second device.

5. The communication system of claim 1 wherein the communication path requirements favor the TDM communication paths.

6. The communication system of claim 1 wherein the communication path requirements favor the packet communication paths.

7. The communication system of claim 1 wherein the communication path requirements favor the hybrid communication paths.

8. The communication system of claim 1 wherein the communication path requirements favor a communication network type if the first device and the second device use the communication network type.

9. The communication system of claim 1 wherein the conditions further comprise switch occupancy in the TDM network.

10. The communication system of claim 1 wherein the conditions further comprise hop count and port utilization in the packet network.

11. A method of operating a communication system, the method comprising:

monitoring a set of conditions for a plurality of communication paths between a first device and a second device wherein the plurality of communication paths comprise at least a time division multiplex (TDM) communication path through a TDM network, a packet communication path through a packet network, and a hybrid communication path through both the TDM network and the packet network, and wherein the set of conditions comprise TDM trunk occupancy and packet latency;

processing the set of conditions and communication path requirements, and in response, selecting one of the plurality of communication paths between the first device and the second device based on the set of conditions and the communication path requirements.

12. The method of claim 11 wherein the first device comprises a telephone.

13. The method of claim 11 wherein the second device comprises a gateway.

14. The method of claim 11 further comprising transferring communications over the selected communication path between the first device and the second device.

15. The method of claim 11 wherein the communication path requirements favor the TDM communication path.

16. The method of claim 11 wherein the communication path requirements favor the packet communication path.

17. The method of claim 11 wherein the communication path requirements favor the hybrid communication path.

18. The method of claim 11 wherein the communication path requirements favor a communication network type if the first device and the second device use the communication network type.

19. The method of claim 11 wherein the conditions further comprise switch occupancy in the TDM network.

20. The method of claim 11 wherein the conditions further comprise hop count and port utilization in the packet network.
