Abstract

A system and method for implementing telephony devices in a distributed network environment is disclosed. The present invention provides for voice transmissions to be given a dedicated virtual local area network (“VLAN”) for packet transmission and reception to prevent poor quality of service. Non-voice data packets are transmitted on a separate VLAN.

Claims

1. A method, comprising:

receiving a request for configuration of a first endpoint;

determining, using a processor, a first virtual local area network associated with voice data packets, wherein a first virtual local area network identifier is associated with the first virtual local area network;

determining, using the processor, a second virtual local area network associated with non-voice data packets, wherein a second virtual local area network identifier is associated with the second virtual local area network;

storing, at a memory, the first virtual local area network identifier and the second virtual local area network identifier, wherein the first virtual local area network identifier is associated with voice data packets and the second virtual local area network identifier is associated with non-voice data packets; and

communicating, to the first endpoint, a first virtual local area network identifier associated with the first virtual local area network, wherein the first endpoint is operable to transmit data packets comprising the first virtual local area network identifier if the data packets are voice data packets.

2. The method of claim 1, further comprising:

receiving voice data packets and non-voice data packets;

communicating the voice data packets to the first virtual local area network;

communicating the non-voice data packets to the second virtual local area network.

3. The method of claim 1, wherein communicating, to the first endpoint, a first virtual local area network identifier comprises communicating the first virtual local area network identifier in a discovery protocol message.

4. The method of claim 1, wherein the first endpoint comprises a telephony device.

5. The method of claim 1, further comprising receiving data packets from the first endpoint, wherein data packets comprise the first virtual local area network identifier if the data packets are voice data packets.

6. The method of claim 5, further comprising communicating an instruction to the first endpoint to verify that the data packets comprise the first virtual local area network identifier, wherein the first endpoint is operable to change the first local area network identifier to the second virtual local area network identifier if the data packets are non-voice data packets.

7. A non-transitory computer readable medium comprising logic, the logic, when executed, operable to:

receive a request for configuration of a first endpoint;

determine a first virtual local area network associated with voice data packets, wherein a first virtual local area network identifier is associated with the first virtual local area network;

determine a second virtual local area network associated with non-voice data packets, wherein a second virtual local area network identifier is associated with the second virtual local area network;

store the first virtual local area network identifier and the second virtual local area network identifier, wherein the first virtual local area network identifier is associated with voice data packets and the second virtual local area network identifier is associated with non-voice data packets; and

communicate a first virtual local area network identifier associated with the first virtual local area network, wherein the first endpoint is operable to transmit data packets comprising the first virtual local area network identifier if the data packets are voice data packets.

8. The non-transitory computer readable medium of claim 7, the logic further operable to:

receive voice data packets and non-voice data packets;

communicate the voice data packets to the first virtual local area network;

communicate the non-voice data packets to the second virtual local area network.

9. The non-transitory computer readable medium of claim 7, wherein communicating, to the first endpoint, a first virtual local area network identifier comprises communicating the first virtual local area network identifier in a discovery protocol message.

10. The non-transitory computer readable medium of claim 7, wherein the first endpoint comprises a telephony device.

11. The non-transitory computer readable medium of claim 7, the logic further operable to receive data packets from the first endpoint, wherein data packets comprise the first virtual local area network identifier if the data packets are voice data packets.

12. The non-transitory computer readable medium of claim 11, the logic further operable to communicate an instruction to the first endpoint to verify that the data packets comprise the first virtual local area network identifier, wherein the first endpoint is operable to change the first local area network identifier to the second virtual local area network identifier if the data packets are non-voice data packets.

13. A network switch, comprising:

an interface operable to receive a request for configuration of a first endpoint;

a processor operable to;

determine a first virtual local area network associated with the voice data packets, wherein a first virtual local area network identifier is associated with the first virtual local area network;

determine a second virtual local area network associated with non-voice data packets, wherein a second virtual local area network identifier is associated with the second virtual local area network;

a memory operable to store the first virtual local area network identifier and the second virtual local area network identifier, wherein the first virtual local area network identifier is associated with voice data packets and the second virtual local area network identifier is associated with non-voice data packets; and

wherein the network switch communicates, to the first endpoint, a first virtual local area network identifier associated with the first virtual local area network, wherein the first endpoint is operable to transmit data packets comprising the first virtual local area network identifier if the data packets are voice data packets.

14. The network switch of claim 13, wherein the interface is operable to:

receive voice data packets and non-voice data packets;

communicate the voice data packets to the first virtual local area network;

communicate the non-voice data packets to the second virtual local area network.

15. The network switch of claim 13, wherein communicating, to the first endpoint, a first virtual local area network identifier comprises communicating the first virtual local area network identifier in a discovery protocol message.

16. The network switch of claim 13, the interface further operable to receive data packets from the first endpoint, wherein data packets comprise the first virtual local area network identifier if the data packets are voice data packets.

17. The network switch of claim 16, the interface further operable to communicate an instruction to the first endpoint to verify that the data packets comprise the first virtual local area network identifier, wherein the first endpoint is operable to change the first local area network identifier to the second virtual local area network identifier if the data packets are non-voice data packets.
