Abstract
A load balancer is provided for balancing distribution of wireless clients among wireless access points. The load balancer includes a tracking implementation for tracking at least one telemetry parameter of each wireless client's wireless link with each respective wireless access point. A goal implementation is included for comparing one or more telemetry parameter against at least one predetermined goal to obtain a fitness measure. A control implementation is also provided for varying the operation of at least one of the respective wireless access points and wireless clients in response to the fitness measure, so as to balance the distribution of load among the respective wireless access points.
Claims19
An apparatus, comprising:
- a tracking device configured for tracking processor performance for a wireless plurality of access points;
- and
- a control device configured for varying the operation of at least one of the plurality of access points to provide balanced access point digital processing performance;
- wherein the control device is operable to perform at least one control action to provide balanced access point digital processing performance;
- and
- wherein the at least one control action is selected from a group consisting of admission control, and varying the signal power of at least one of the plurality of wireless access points.
A method, comprising:
- tracking processor performance for a plurality of access points;
- and
- performing at least one control action that varies the operation of at least one of the plurality of access points to provide balanced access point digital processing performance;
- wherein the at least one control action is selected from a group consisting of admission control, and varying the signal power of at least one of the plurality of wireless access points.
An apparatus, comprising:
- a tracking device configured for tracking processor performance for a plurality of access points having wireless links with a plurality of wireless clients;
- and
- a control device configured for varying the operation of at least one of the plurality of wireless clients to provide balanced access point digital processing performance;
- wherein the control device is operable to perform at least one control action to provide balanced access point digital processing performance;
- and
- wherein the at least one control action is selected from a group consisting of wireless client admission control, changing operating frequency of at least one of the plurality of wireless clients.
An apparatus, comprising:
- a tracking device configured for tracking multipath for each wireless link for a plurality of wireless access points;
- and
- a control device for varying the operation of at least one of the plurality of wireless access points so as to minimize multipath for a wireless link of the at least one of the plurality of wireless access point;
- wherein the control device is operable to perform at least one control action to vary the operation of the at least one of the plurality of wireless access points;
- and
- wherein the at least one control action is selected from a group consisting of admission control, and varying the signal power of the at least one of the plurality of wireless access points.
A method, comprising:
- tracking multipath for each wireless link for a plurality of wireless access points;
- and
- varying the operation of at least one of the respective wireless access points so as to minimize multipath for at least one wireless link for the at least one of the plurality of wireless access points;
- wherein varying the operation is selected from a group consisting of admission control, and varying the signal power of at least one of the plurality of wireless access points.
An apparatus, comprising:
- a tracking device configured for tracking multipath for a plurality of wireless clients;
- and
- a control device for varying the operation of at least one of the wireless clients so as to minimize multipath for at least one wireless client's wireless link;
- wherein the control device is operable to perform at least one control action to vary the operation of at least one of the plurality of wireless clients;
- and
- wherein the at least one control action is selected from a group consisting of client admission control, and varying the signal power of at least one of the plurality of wireless clients.
