Abstract

A wireless network device that assigns priorities to communications in a network has a first circuit for receiving wireless messages from remote wireless network devices and a second circuit operable to send wireless messages to the remote wireless network devices. A third circuit makes a determination of the relative priorities of the remote wireless network devices. The wireless network device is operable to form a message to the remote wireless network devices, where the message is used to set a backoff time in the remote wireless network devices. The backoff time sent to the remote wireless network device is related to the relative priority of the remote wireless network device.

Claims

1. A wireless network device comprising:

a first circuit for receiving wireless messages from remote wireless network devices;

a second circuit for sending wireless messages to the remote wireless network devices;

a third circuit for monitoring and analyzing the nature of network traffic between the wireless network device and each of the remote wireless devices;

a fourth circuit for making a determination of the relative priorities of the various remote wireless network devices, the fourth circuit determining the priority of one of the remote wireless network devices based at least in part on the volume of network traffic between the wireless network device and the one of the remote wireless network devices, wherein the fourth circuit increases the priority of the one remote wireless device to a higher priority in response to the third circuit determining that the volume of network traffic has increased beyond a predetermined threshold;

a fifth circuit for forming a message to the remote wireless network devices, the message operable to set a backoff time in the one remote wireless network device, the backoff time related to the relative priority of the one remote wireless network device; and

the second circuit operable to send the message from the fifth circuit to the one remote wireless network device.

2. The device of claim 1, further comprising a sixth circuit for allowing operator input information into the wireless network device, wherein the fourth circuit further determines priority based at least in part on the information input at the sixth circuit, as well as any network traffic increase.

3. The device of claim 1, wherein the fourth circuit further determines priority based at least in part on receiving a request from one of the remote wireless devices for a change in priority level for that remote wireless device.

4. The device of claim 3, wherein the fourth circuit determines whether to accept the request for a change in priority, and if accepted, whether the change is to be accepted in whole or in part.

5. The device of claim 4, wherein there are multiple levels of priority, wherein the request for a change in priority is for more than one level in priority, and wherein the request accepted in part is a change in priority to fewer levels than that requested.

6. The device of claim 1, wherein the relative priority determined at the fourth circuit is assigned to only specific data streams transmitted to one of the remote wireless devices.

7. The device of claim 1, wherein the third circuit is responsive to a newly detected remote network device, and wherein the fifth circuit forms a message to the newly detected remote device assigning a relative priority to the newly detected remote device.
