Abstract

The present invention includes a network telephone having a microphone coupled to provide voice data to a network, a speaker coupled to facilitate listening to voice data from the network, a dialing device coupled to facilitate routing of voice data upon the network, a first port configured to facilitate communication with a first network device, a second port configured to facilitate communication with a second network device and a prioritization circuit coupled to apply prioritization to voice data provided by the microphone.

Claims

1. A controller for communicating a data packet over a network, comprising:

a switch engine queuing manager configured to classify the data packet as a first type or a second type and to prioritize a first type data packet according to a first priority and a second type data packet according to a second priority, the first priority being higher than the second priority; and

a packet buffer including a first queue and a second queue, the switch engine queuing manager being further configured to queue the first type data packet into the first queue and the second type data packet into the second queue.

2. The controller of claim 1, wherein the packet buffer is further configured to dequeue the first type data packet from the first queue ahead of the second type data packet from the second queue.

3. The controller of claim 1, wherein the switch engine queuing manager is further configured to queue the first type data packet into the first queue in an order the first type data packet was transmitted.

4. The controller of claim 3, wherein the switch engine queuing manager is further configured to queue an earlier transmitted first type data packet before a later transmitted first type data packet when the later transmitted first type data packet is received before the earlier transmitted first type data packet.

5. The controller of claim 3, wherein the switch engine queuing manager is further configured to delete an earlier transmitted first type data packet.

6. The controller of claim 1, wherein the packet buffer further includes a plurality of first queues and a plurality of second queues, the first queue and the second queue being from among the plurality of first queues and the plurality of second queues, respectively, each of the plurality of first queues and a corresponding one of the plurality second queues being associated with a destination of the first type data packet and the second type data packet from among a plurality of destinations.

7. The controller of claim 6, further comprising:

an address lookup engine configured to determine the destination of the first type data packets and the second type data packets, and

wherein the switch engine queuing manager is further configured to queue the first type data packet into the first queue associated with its respective destination and the second type data packet into the second queue associated with its respective destination.

8. The controller of claim 7, wherein the first type data packet from the first queue is associated with its respective destination ahead of when the second type data packets from the second queue is associated with its respective destination.

9. A controller for communicating a data packet over a network, comprising:

means for determining whether the data packet is a first type data packet or a second type data packet;

means for prioritizing the first type data packet according to a first priority and the second type data packet according to a second priority, the first priority being higher than the second priority; and

means for queuing the first type data packet into a first queue and the second type data packet into a second queue.

10. The controller of claim 9, further comprising:

means for dequeuing the first type data packet from the first queue ahead of the second type data packet from the second queue.

11. The controller of claim 9, wherein the means for queuing is configured to queue the first type data packet into the first queue in an order the first type data packet was transmitted.

12. The controller of claim 11, wherein the means for queuing is configured to queue an earlier transmitted first type data packet before a later transmitted first type data packet when the later transmitted first type data packet is received before the earlier transmitted first type data packet.

13. The of claim 11, further comprising:

means for deleting an earlier transmitted first type data packet.

14. The controller of claim 9, wherein the first queue is selected from among a plurality of first queues, and wherein the second queue is selected from among a plurality of second queues, each of the plurality of first queues and a corresponding one of the plurality of the second queues being associated with a destination of the first type data packet and the second type data packet from among a plurality of destinations.

15. The controller of claim 14, further comprising:

means for determining the destination of the first type data packet and the second type data packet from among the plurality of destinations, and

wherein the means for queuing is configured to queue the first type data packet into the first queue associated with its respective destination and the second type data packet into the second queue associated with its respective destination.

16. The controller of claim 15, further comprising:

means for dequeuing the first type data packet from the first queue associated with its respective destination ahead of the second type data packet from the second queue associated with its respective destination.

17. A method for communicating a data packet over a network, comprising:

determining, by a controller, whether the data packet is a first type data packet or a second type data packet;

prioritizing, by the controller, the first type data packet according to a first priority and the second type data packet according to a second priority, the first priority being higher than the second priority; and

queuing, by the controller, the first type data packet into a first queue and the second type data packet into a second queue.

18. The method of claim 17, farther comprising:

dequeuing the first type data packet from the first queue ahead of the second type data packet from the second queue.

19. The method of claim 17, wherein the first queue is selected from among a plurality of first queues, and wherein the second queue is selected from among a plurality of second queues, each of the plurality of first queues and a corresponding one of the plurality of second queues being associated with a destination of the first type data packet and the second type data packet from among a plurality of destinations, the method farther comprising:

determining the destination of the first type data packet and the second type data packet from among the plurality of destinations, and

Wherein the queuing comprises;

queuing the first type data packet into the first queue associated with its respective destination and the second type data packet into the second queue associated with its respective destination.

20. The method of claim 19, further comprising:

dequeuing the first type data packet from the first queue associated with its respective destination ahead of the second type data packet from the second queue associated with its respective destination.
