Abstract

An information handling system operating a mesh network link aggregation optimization system may comprise a plurality of mesh access points, and one or more client devices connected via a plurality of wireless links forming a mesh wireless network. A processor may execute code instructions to generate a congestion score for each of the links based on measured traffic and quality of service of each of the links, determine the congestion score for a congested link does not meet a preset congestion threshold value, determine a location within the mesh wireless network in which to aggregate links between two mesh access points, based on availability of one or more radios, and transmit an instruction to one of the plurality of mesh access points to aggregate two or more links at the network layer at the determined location for simultaneous transmission on a single band.

receive measured traffic and quality of service of each of the plurality of links;

generate a congestion score for each of the plurality of wireless links based on the measured traffic and quality of service of each of the plurality of links;

determine the congestion score for a congested one of the plurality of wireless links does not meet a preset congestion threshold value;

determine a location within the mesh wireless network in which to aggregate links between two of the plurality of mesh access points, based on availability of one or more radios at one or more of the plurality of mesh access points; and

transmit a command to a first one of the plurality of mesh access points to aggregate two or more links at a network layer at the determined location for simultaneous transmission on a single band to a second one of the plurality of mesh access points such that each of the plurality of links has a congestion score that meets or exceeds the preset congestion threshold value.

2. The information handling system of claim 1 , wherein the single band on which the two or more links are aggregated is the 5 GHz band.

3. The information handling system of claim 1 , wherein the single band on which the two or more links are aggregated is the 2.4 GHz band.

4. The information handling system of claim 1 , wherein the single band on which the two or more links are aggregated is the 60 GHz band.

5. The information handling system of claim 1 further comprising:

determining a first of the one or more client devices is not operating as an access point within the mesh wireless network to transmit or receive data to or from a plurality of access points or other client devices; and

instructing the first one of the one or more client devices not operating as an access point to act as a mesh access point to transmit or receive data to or from a plurality of access points or other client devices.

6. The information handling system of claim 5 further comprising:

a processor of the first of the one or more client devices instructed to operate as a mesh access point aggregating the two or more links for simultaneous transmission on the single band.

7. The information handling system of claim 5 further comprising:

the processor executing code instructions of an ad-hoc routing algorithm to determine optimal link configurations between each of the plurality of mesh access points, and the one or more client devices.

8. A method of optimizing links aggregated at the network layer across a wireless mesh network comprising:

measuring via a process traffic and quality of service of each of a plurality of links routed by a plurality of antenna front ends between a plurality of mesh access points, and one or more client devices within a mesh wireless network;

generating a congestion score for each of the plurality of wireless links based on the measured traffic and quality of service of each of the plurality of links;

determining the congestion score for a congested one of the plurality of wireless links does not meet a preset congestion threshold value;

determining a first one of the one or more client devices is not operating as an access point within the mesh wireless network to transmit or receive data to or from a plurality of access points or other client devices;

determining a location within the mesh wireless network in which to aggregate links between two of the plurality of mesh access points based on usage at one or more of the plurality of mesh access points of a radio sharing method; and

aggregating two or more links at the determined location for simultaneous transmission on a single band via a front end of a first one of the plurality of mesh access points to a second one of the plurality of mesh access points such that each of the plurality of links has a congestion score that meets or exceeds the preset congestion threshold value.

9. The method of claim 8 further comprising:

performing an ad-hoc routing algorithm to determine optimal link configurations between each of the plurality of mesh access points, and the one or more client devices.

10. The method of claim 9 further comprising:

determining a preset optimization timer has elapsed;

repeating the ad-hoc routing algorithm; and

repeating the method of optimizing links aggregated at the network layer across a wireless mesh network.

11. The method of claim 8 further comprising:

determining a preset optimization timer has elapsed; and
