Abstract

A method provided in one embodiment includes determining a first resource indicator indicative of a first resource capability of a first network element, determining a second resource indicator indicative of a second resource capability of the first network element, determining a third resource indicator indicative of a third resource capability of the first network element, and sending the first resource indicator, the second resource indicator, and the third resource indicator to a second network element. The second network element is configured to determine a first metric value for the first network element based upon the first resource indicator, the second resource indicator, and the third resource indicator. The second network element is further configured to utilize the first metric value to determine a list of one or more acceptable network elements for a wireless device to establish a connection therewith.

First claim

What is claimed is:

1. A method, comprising:
determining a first resource indicator indicative of a first resource capability of a first network element, wherein the first resource indicator is indicative of an additional number of wireless devices that the first network element can support in a predetermined time interval;
determining a second resource indicator indicative of a second resource capability of the first network element, wherein the second resource indicator is indicative of a hardware load of the first network element at a predetermined time;
determining a third resource indicator indicative of a third resource capability of the first network element; and
sending the first resource indicator, the second resource indicator, and the third resource indicator to a second network element, wherein the second network element is configured to determine a first metric value for the first network element based upon the first resource indicator, the second resource indicator, and the third resource indicator, and wherein the second network element is further configured to utilize the first metric value to determine a list of one or more acceptable network elements for a wireless device to establish a connection therewith.

2. The method of claim 1 , wherein the second resource indicator includes a value indicative of either a low hardware load, a medium hardware load, or a high hardware load upon the first network element.

3. The method of claim 1 , wherein the third resource indicator is indicative of a fraction of flows traversing the first network element for which a quality of service (QoS) requirement was violated.

4. The method of claim 1 , wherein sending one or more of the first resource indicator, the second resource indicator, and the third resource indicator to the second network element includes including one or more of the first resource indicator, the second resource indicator, and the third resource within a Constrained Application Protocol (CoAP) protocol message.

5. The method of claim 4 , wherein the CoAP protocol message is a CoAP Observe message.

6. The method of claim 4 , wherein at least one of the first resource indicator, the second resource indicator, and the third resource indicator are included in an option field of the CoAP protocol message.

7. The method of claim 1 , further comprising:
receiving the list of one or more network elements; and
sending the list of one or more acceptable network elements to the wireless device.

8. The method of claim 7 , wherein sending the list of one or more acceptable network elements includes sending the list of one or more acceptable network elements within at least one of a WiFi beacon message, a WiFi probe response message, or a cellular random access procedure message.

9. The method of claim 1 , wherein the first network element includes a wireless access point.

10. The method of claim 1 , wherein the second network element includes a server.

11. Logic encoded in one or more non-transitory media that includes code for execution and when executed by a processor operable to perform operations comprising:
determining a first resource indicator indicative of a first resource capability of a first network element, wherein the first resource indicator is indicative of an additional number of wireless devices that the first network element can support in a predetermined time interval;
determining a second resource indicator indicative of a second resource capability of the first network element, wherein the second resource indicator is indicative of a hardware load of the first network element at a predetermined time;
determining a third resource indicator indicative of a third resource capability of the first network element; and
sending the first resource indicator, the second resource indicator, and the third resource indicator to a second network element, wherein the second network element is configured to determine a first metric value for the first network element based upon the first resource indicator, the second resource indicator, and the third resource indicator, and wherein the second network element is further configured to utilize the first metric value to determine a list of one or more acceptable network elements for a wireless device to establish a connection therewith.

12. The logic of claim 11 , wherein the second resource indicator includes a value indicative of either a low hardware load, a medium hardware load, or a high hardware load upon the first network element.

13. The logic of claim 11 , wherein the third resource indicator is indicative of a fraction of flows traversing the first network element for which a quality of service (QoS) requirement was violated.

14. The logic of claim 11 , further comprising:
receiving the list of the one or more acceptable network elements; and
sending the list of one or more acceptable network elements to the wireless device.

15. A first network element, comprising:
a memory element configured to store electronic code;
a processor operable to execute instructions associated with the electronic code; and
a module coupled to the memory element and the processor, wherein the first network element is configured for:
determining a first resource indicator indicative of a first resource capability of the first network element, wherein the first resource indicator is indicative of an additional number of wireless devices that the first network element can support in a predetermined time interval;
determining a second resource indicator indicative of a second resource capability of the first network element, wherein the second resource indicator is indicative of a hardware load of the first network element at a predetermined time;
determining a third resource indicator indicative of a third resource capability of the first network element; and
sending the first resource indicator, the second resource indicator, and the third resource indicator to a second network element, wherein the second network element is configured to determine a first metric value for the first network element based upon the first resource indicator, the second resource indicator, and the third resource indicator, and wherein the second network element is further configured to utilize the first metric value to determine a list of one or more acceptable network elements for a wireless device to establish a connection therewith.

16. The first network element of claim 15 , wherein the second resource indicator includes a value indicative of either a low hardware load, a medium hardware load, or a high hardware load upon the first network element.

17. The first network element of claim 1 , wherein the third resource indicator is indicative of a fraction of flows traversing the first network element for which a quality of service (QoS) requirement was violated.

18. The first network element of claim 15 , wherein the first network element is configured for:
receiving the list of the one or more acceptable network elements; and
sending the list of one or more acceptable network elements to the wireless device.

19. The first network element of claim 15 , wherein the first network element includes a wireless access point.
