Abstract

A traffic management system for managing communication traffic on wireless local area networks (WLAN)s. The traffic management system comprises: a traffic aggregator and a traffic prioritizer. The traffic aggregator is configured to aggregate traffic management parameters from neighboring ones of the WLANs which share a selected communication channel with one another for communication links between their associated wireless access point (WAP) node and station nodes. The traffic prioritizer is coupled to the traffic aggregator and configured to prioritize the communication traffic of the neighboring ones of the WLANs using the aggregated traffic management parameters; thereby avoiding impediments to high priority communication traffic on a one of the neighboring networks resulting from a lack of prioritization coordination with an other of the neighboring networks.

First claim

What is claimed is:

1. A traffic management system for managing communication traffic on wireless local area networks (WLAN)s each including a wireless access point (WAP) supporting wireless communications with associated stations on a selected one of a plurality of communication channels, and the traffic management system comprising:
a traffic aggregator to aggregate traffic management parameters from neighboring ones of the WLANs which share the selected communication channel with one another and to determine if available airtime for communication traffic on the neighboring ones of the WLANs falls below a threshold level;
a traffic prioritizer coupled to the traffic aggregator and responsive to a determination by the traffic aggregator of available airtime below the threshold level, to prioritize communication traffic on the neighboring ones of the WLANs using the aggregated traffic management parameters; thereby avoiding impediments to high priority communication traffic on a one of the neighboring networks resulting from a lack of prioritization coordination with an other of the neighboring networks.

2. The traffic management system of claim 1 , further comprising:
the traffic prioritizer further configured to detect an absence of a highest priority type of communication traffic on the neighboring ones of the WLANs and responsive thereto, to elevate a quality of service (QOS) and reduce the backoff times associated with transmitting remaining communication traffic.

3. A traffic management system for managing communication traffic on wireless local area networks (WLAN)s, and the traffic management system comprising:
a traffic aggregator configured to aggregate traffic management parameters from neighboring ones of the WLANs which share a selected communication channel with one another for communication links between their associated wireless access point (WAP) node and station nodes; and further to determine available unused airtime for communication traffic on the neighboring ones of the WLANs; and
a traffic prioritizer coupled to the traffic aggregator and configured to prioritize communication traffic on the neighboring ones of the WLANs using the aggregated traffic management parameters; thereby avoiding impediments to high priority communication traffic on a one of the neighboring networks resulting from a lack of prioritization coordination with an other of the neighboring networks, and further to limit prioritization of communication traffic to neighboring ones of the WLANs having available airtime below a threshold level.

4. The traffic management system of claim 1 , further comprising:
the traffic prioritizer further configured to accord distinct priorities to communication traffic on the neighboring ones of the WLANs, based on differences in WLAN subscriber service types between the neighboring ones of the WLANs.

5. A method for communication traffic management on wireless local area networks (WLAN)s each including a wireless access point (WAP) supporting wireless communications with associated stations on a selected one of a plurality of communication channels, and the method comprising:
aggregating traffic management parameters from neighboring ones of the WLANs which share the selected communication channel with one another;
determining if available airtime for communication traffic on the neighboring ones of the WLANs falls below a threshold level, based on the traffic management parameters aggregated in the aggregating act;
prioritizing communication traffic on the neighboring ones of the WLANs using the aggregated traffic management parameters; responsive to a determination in the determining act that available airtime on the neighboring ones of the WLANs falls below a threshold level; thereby avoiding impediments to high priority communication traffic on a one of the neighboring networks resulting from a lack of prioritization coordination with an other of the neighboring networks.

6. The method of claim 5 , wherein the prioritizing act, further comprises:
detecting an absence of a highest priority type of communication traffic on the neighboring ones of the WLANs; and responsive to the detecting act;
elevating a quality of service (QOS) associated with remaining communication traffic; and
reducing backoff times associated with transmitting the remaining communication traffic.

7. A method for communication traffic management on wireless local area networks (WLAN)s, and the method comprising:
aggregating traffic management parameters from neighboring ones of the WLANs which share a selected communication channel with one another for communication links between their associated wireless access point (WAP) node and station nodes;
determining available unused airtime for communication traffic on the neighboring ones of the WLANs;
prioritizing communication traffic on the neighboring ones of the WLANs using the aggregated traffic management parameters; thereby avoiding impediments to high priority communication traffic on a one of the neighboring networks resulting from a lack of prioritization coordination with an other of the neighboring networks; and
limiting prioritization of communication traffic to neighboring ones of the WLANs having available airtime below a threshold level.

8. The method of claim 5 , wherein the prioritizing act, further comprises:
according distinct priorities to communication traffic on the neighboring ones of the WLANs, based on differences in WLAN subscriber service types between the neighboring ones of the WLANs.
