Abstract

A system is configured to provide a self-healing-based auto radio resource management (RRM) tuning of a network that allows for a closed-loop and domain specific transition from steady state, or a maintenance, mode to a startup, or a configuration, mode depending on the health score of the network. The ability to switch between network state modes seamlessly upon determining when a startup mode is necessary to improve performance based on the monitoring of a health score, through the monitoring and tracking of the overall network health and performance.

Claims (48)

1 . A method for triggering a reconfiguration of a Wi-Fi network using an aggressive convergence radio resource management (RRM) mode in a previously configured Wi-Fi network, the method comprising:

detecting that a reconfiguration threshold has been reached for at least a portion of the Wi-Fi network, the reconfiguration threshold indicating that configurations of a significant number of access points in the at least the portion of the Wi-Fi network are below a defined health-score value, to obtain a detection result; and

switching, based on the detection result, to the aggressive convergence RRM mode from a conservative convergence RRM mode, wherein the aggressive convergence RRM mode comprises performing configuration cycles without waiting for a predefined maintenance interval, and wherein the conservative convergence RRM mode comprises performing configuration cycles only at predefined maintenance intervals.

2 . The method of claim 1 , wherein the aggressive convergence RRM mode is characterized by a low hysteresis parameter, wherein the conservative convergence RRM mode is characterized by a high hysteresis parameter, and wherein hysteresis parameters function to discourage updates to access point reconfigurations such that when a hysteresis parameter is high, less reconfigurations are made to the access points.

3 . The method of claim 1 , wherein the reconfiguration threshold is based on an aggregate health score for the access points in the at least the portion of the Wi-Fi network, the reconfiguration threshold being a percentage reduction in the aggregate health score for the access points in the at least the portion of the Wi-Fi network.

4 . The method of claim 1 , wherein the reconfiguration threshold is based on an increase in a number of channel changes or power level changes by the access points in the at least the portion of the Wi-Fi network, the reconfiguration threshold being a percentage increase in the number of the channel changes or the power level changes.

5 . The method of claim 1 , wherein the aggressive convergence RRM mode comprises:

determining first configuration recommendations based on information descriptive of the access points in the at least the portion of the Wi-Fi network;

instructing the access points in the at least the portion of the Wi-Fi network to undergo a first reconfiguration based on the first configuration recommendations;

receiving first telemetry from the access points in the at least the portion of the Wi-Fi network that are configured based on the first configuration recommendations;

determining second configuration recommendations based on the first telemetry and the information descriptive of the access points;

instructing the access points in the at least the portion of the Wi-Fi network to undergo a second reconfiguration based on the second configuration recommendations; and

determining a number of changes in the second configuration recommendations.

6 . The method of claim 5 , further comprising

repeating a cycle of the determining second configuration recommendations and the instructing the access points in the at least the portion of the Wi-Fi network to undergo the second reconfiguration, when the determined number of changes in the second configuration recommendations is above a threshold.

7 . The method of claim 5 , further comprising returning to the conservative convergence RRM mode when the determined number of changes in the second configuration recommendations is below a threshold.

8 . The method of claim 5 , wherein the number of changes in the second configuration recommendations is a number of channel changes, channel width changes, or transmission power changes.

9 . A network device comprising:

one or more memories having computer-readable instructions stored therein; and

one or more processors configured to execute the computer-readable instructions to:

detect that a reconfiguration threshold has been reached for at least a portion of a Wi-Fi network, the reconfiguration threshold indicating that configurations of a significant number of access points in the at least the portion of the Wi-Fi network are below a defined health-score value, to obtain a detection result; and

switch, based on the detection result, to an aggressive convergence radio resource management (RRM) mode from a conservative convergence RRM mode, wherein the aggressive convergence RRM mode comprises performing configuration cycles without waiting for a predefined maintenance interval, and wherein the conservative convergence RRM mode comprises performing configuration cycles only at predefined maintenance intervals.

10 . The network device of claim 9 , wherein the aggressive convergence RRM mode is characterized by a low hysteresis parameter, wherein the conservative convergence RRM mode is characterized by a high hysteresis parameter, and wherein hysteresis parameters function to discourage updates to access point reconfigurations such that when a hysteresis parameter is high, less reconfigurations are made to the access points.

11 . The network device of claim 9 , wherein the reconfiguration threshold is based on an aggregate health score for the access points in the at least the portion of the Wi-Fi network, the reconfiguration threshold being a percentage reduction in the aggregate health score for the access points in the at least the portion of the Wi-Fi network.

12 . The network device of claim 9 , wherein the reconfiguration threshold is based on an increase in a number of channel changes or power level changes by the access points in the at least the portion of the Wi-Fi network, the reconfiguration threshold being a percentage increase in the number of the channel changes or the power level changes.

13 . The network device of claim 9 , wherein the aggressive convergence RRM mode comprises:

determine first configuration recommendations based on information descriptive of the access points in the at least the portion of the Wi-Fi network;

instruct the access points in the at least the portion of the Wi-Fi network to undergo a first reconfiguration based on the first configuration recommendations;

receive first telemetry from the access points in the at least the portion of the Wi-Fi network that are configured based on the first configuration recommendations;

determine second configuration recommendations based on the first telemetry and the information descriptive of the access points;

instruct the access points in the at least the portion of the Wi-Fi network to undergo a second reconfiguration based on the second configuration recommendations; and

determine a number of changes in the second configuration recommendations.

14 . The network device of claim 13 , wherein the instructions further configure the network device to:

repeat a cycle of the determining second configuration recommendations and the instructing the access points in the at least the portion of the Wi-Fi network to undergo the second reconfiguration, when the determined number of changes in the second configuration recommendations is above a threshold.

15 . The network device of claim 13 , wherein the instructions further configure the network device to return to the conservative convergence RRM mode when the determined number of changes in the second configuration recommendations is below a threshold.

16 . A non-transitory computer-readable medium comprising computer-readable instructions, which when executed by one or more processors of a network appliance, cause the network appliance to:
