Abstract

A method includes receiving, on a first network device, an announcement message from an endpoint device connected to the first network device via a network connection. The announcement message, which includes at least one connection criteria, is transmitted to one or more downstream network devices.

Claims

1. A method comprising:

receiving, on a first network device, an announcement message from an endpoint device connected to the first network device via a first network connection, wherein the announcement message includes at least one connection criteria;

modifying the announcement message to include information associated with the first network device;

configuring at least one traffic policy of the first network device in accordance with the at least one connection criteria, wherein the at least one traffic policy is associated with a second network connection; and

transmitting the modified announcement message to one or more downstream network devices.

2. The method of claim 1 wherein the endpoint device is a VoIP telephony endpoint device.

3. The method of claim 1 wherein the announcement message is in conformance with an 802.1AB link layer discovery protocol.

4. The method of claim 1 further comprising:

processing the modified announcement message received by the one or more downstream network devices; and

configuring at least one traffic policy of the one or more downstream network devices in accordance with the at least one connection criteria.

5. The method of claim 1 wherein the first network device is chosen from the group consisting of:

a switching device;

a routing device;

a bridge;

a gateway;

an access point;

a repeating device;

a signal forwarding device;

a packet forwarding device; and

a server.

16. The method of claim 1 wherein the information associated with the first network device includes one or more of:

configuration information, status information, and policy information.

17. The method of claim 1 wherein the information associated with the first network device further includes one or more of:

network configuration information and network status information.

18. The method of claim 1 further comprising:

forwarding packets based, at least in part, upon the at least one traffic policy.

6. An apparatus comprising an integrated circuit, wherein the integrated circuit is capable of:

receiving, on a first network device, an announcement message from an endpoint device connected to the first network device via a first network connection, wherein the announcement message includes at least one connection criteria;

modifying the announcement message to include information associated with the first network device;

configuring at least one traffic policy of the first network device in accordance with the at least one connection criteria, wherein the at least one traffic policy is associated with a second network connection; and

transmitting the modified announcement message to one or more downstream network devices.

7. The apparatus of claim 6 wherein the endpoint device is a VoIP telephony endpoint device.

8. The apparatus of claim 6 wherein the announcement message is in conformance with an 802.1AB link layer discovery protocol.

9. The apparatus of claim 6 wherein the integrated circuit is further capable of:

processing the modified announcement message received by the one or more downstream network devices; and

configuring at least one traffic policy of the one or more downstream network devices in accordance with the at least one connection criteria.

10. The apparatus of claim 6 wherein the first network device is chosen from the group consisting of:

a switching device;

a routing device;

a bridge;

a gateway;

an access point;

a repeating device;

a signal forwarding device;

a packet forwarding device; and

a server.

19. The apparatus of claim 6 wherein the information associated with the first network device includes one or more of:

configuration information, status information, and policy information.

20. The apparatus of claim 6 wherein the information associated with the first network device further includes one or more of:

network configuration information and network status information.

21. The apparatus of claim 6 wherein the integrated circuit is further capable of:

forwarding packets based, at least in part, upon the at least one traffic policy.

22. The computer program product of claim 21 wherein the information associated with the first network device includes one or more of:

configuration information, status information, and policy information.

23. The computer program product of claim 21 wherein the information associated with the first network device further includes one or more of:

network configuration information and network status information.

24. The computer program product of claim 21 further comprising instructions for:

forwarding packets based, at least in part, upon the at least one traffic policy.

11. A computer program product residing on a computer readable medium having a plurality of instructions stored thereon which, when executed by the processor, cause that processor to:

receive, on a first network device, an announcement message from an endpoint device connected to the first network device via a first network connection, wherein the announcement message includes at least one connection criteria;

modify the announcement message to include information associated with the first network device;

configure at least one traffic policy of the first network device in accordance with the at least one connection criteria, wherein the at least one traffic policy is associated with a second network connection; and

transmit the modified announcement message to one or more downstream network devices.

12. The computer program product of claim 11 wherein the endpoint device is a VoIP telephony endpoint device.

13. The computer program product of claim 11 wherein the announcement message is in conformance with an 802.1AB link layer discovery protocol.

14. The computer program product of claim 11 further comprising instructions for:

processing the modified announcement message received by the one or more downstream network devices; and

configuring at least one traffic policy of the one or more downstream network devices in accordance with the at least one connection criteria.

15. The computer program product of claim 11 wherein the first network device is chosen from the group consisting of:

a switching device;

a routing device;

a bridge;

a gateway;

an access point;

a repeating device;

a signal forwarding device;

a packet forwarding device; and

a server.
