Abstract

Disclosed are systems and methods that provide a computerized network management framework that adaptively configures a network at a location to ensure connectivity and/or network services are maintained. The disclosed framework enables the implementation of multi-link operation (MLO) functionality within WiFi 7 enabled networks to implement non-disruptive channel availability check (CAC) capabilities. The framework can utilize MLO backup/redundant links that can mitigate network disruptions in service/connectivity for client devices that are WiFi 7 capable and utilize MLO functionality by diverting network traffic to an activated MLO link while an available channel/radio (e.g., 5 GHz) is used to perform the CAC operations.

First claim

What is claimed is:

1 . A method comprising:
identifying, over a network, a multi-link operation (MLO) network connection between a set of devices, the set of devices comprising at least one client device and an access point (AP) device connected over the network via first link of the MLO network connection; determining to perform channel availability check (CAC) operations for the network connection; activating, based on the CAC operations determination, a second link of the MLO connection, the second link being a dormant MLO link prior to the activation; offloading, over the network, network traffic between the at least one client device and the AP device to the second link of the MLO connection; and execute, upon the offloading of the network traffic, the CAC operations on the first link of the MLO network connection.

2 . The method of claim 1 , further comprising:
determining completion of the CAC operations on the first link of the MLO network connection; and re-routing, based on the determined completion of the CAC operations, the network traffic back to the first link of the MLO network connection.

3 . The method of claim 2 , further comprising:
rendering the second link of the MLO network connection dormant upon performance of the re-routing of the network traffic back to the first link of the MLO network connection.

4 . The method of claim 2 , wherein the re-routing is performed in accordance with regulatory compliance associated with a location of the network.

5 . The method of claim 1 , further comprising:
monitoring, over the network, the network connection based on at least one criteria; and performing, based on the monitoring, the determination to perform the CAC operations.

6 . The method claim 1 , wherein the first link of the MLO network connection corresponds a 5 GHz frequency band.

7 . The method of claim 1 , wherein the second link of the MLO network connection corresponds to a 2.4 GHz frequency band.

8 . The method of claim 1 , wherein the second link of the MLO network connection corresponds to a 6 GHz frequency band.

9 . The method of claim 1 , wherein the CAC operations are performed upon initiation of the MLO network connection of the at least one client device.

10 . The method of claim 1 , wherein the network is a Wireless Fidelity (WiFi) 7 network at a location, the WiFi 7 network provided via the AP device.

11 . A system comprising:
a processor configured to:
identify, over a network, a multi-link operation (MLO) network connection between a set of devices, the set of devices comprising at least one client device and an access point (AP) device connected over the network via first link of the MLO network connection;
determine to perform channel availability check (CAC) operations for the network connection;
activate, based on the CAC operations determination, a second link of the MLO connection, the second link being a dormant MLO link prior to the activation;
offload, over the network, network traffic between the at least one client device and the AP device to the second link of the MLO connection; and
execute, upon the offloading of the network traffic, the CAC operations on the first link of the MLO network connection.

12 . The system of claim 11 , wherein the processor is further configured to:
determine completion of the CAC operations on the first link of the MLO network connection; and re-route, based on the determined completion of the CAC operations, the network traffic back to the first link of the MLO network connection.

13 . The system of claim 12 , wherein the processor is further configured to:
render the second link of the MLO network connection dormant upon performance of the re-routing of the network traffic back to the first link of the MLO network connection.

14 . The system of claim 12 , wherein the re-routing is performed in accordance with regulatory compliance associated with a location of the network.

15 . The system of claim 11 , wherein the processor is further configured to:
monitor, over the network, the network connection based on at least one criteria; and perform, based on the monitoring, the determination to perform the CAC operations.

16 . A non-transitory computer-readable storage medium tangibly encoded with computer-executable instructions that when executed by a processor, perform a method comprising:
identifying, over a network, a multi-link operation (MLO) network connection between a set of devices, the set of devices comprising at least one client device and an access point (AP) device connected over the network via first link of the MLO network connection; determining to perform channel availability check (CAC) operations for the network connection; activating, based on the CAC operations determination, a second link of the MLO connection, the second link being a dormant MLO link prior to the activation; offloading, over the network, network traffic between the at least one client device and the AP device to the second link of the MLO connection; and execute, upon the offloading of the network traffic, the CAC operations on the first link of the MLO network connection.

17 . The non-transitory computer-readable storage medium of claim 16 , further comprising:
determining completion of the CAC operations on the first link of the MLO network connection; and re-routing, based on the determined completion of the CAC operations, the network traffic back to the first link of the MLO network connection.

18 . The non-transitory computer-readable storage medium of claim 17 , further comprising:
rendering the second link of the MLO network connection dormant upon performance of the re-routing of the network traffic back to the first link of the MLO network connection.

19 . The non-transitory computer-readable storage medium of claim 17 , wherein the re-routing is performed in accordance with regulatory compliance associated with a location of the network.

20 . The non-transitory computer-readable storage medium of claim 16 , further comprising:
monitoring, over the network, the network connection based on at least one criteria; and performing, based on the monitoring, the determination to perform the CAC operations.
