Abstract: Implementations of the present disclosure relate to automatic AP failure recovery with assistance of a neighbor AP. A method includes detecting, by a first access point (AP), a failure at the first AP. The method further includes transmitting, by the first AP to a second AP, a query about an operating status of the second AP. The first AP then receives, from the second AP, a response to the query, the response indicating the operating status of the second AP. The method also includes determining, by the first AP and based at least in part on the operating status of the second AP, that the failure is not indicative of an event also impacting the second AP. The method further includes utilizing, by the first AP, the second AP to assist with recovery from the failure.

Abstract: Implementations of the present disclosure relate to setting a system time of an access point (AP) for server certificate validation. A method comprises obtaining a default time as a system time of the AP after an AP boots up. The method also comprises obtaining a memory time from a flash memory of the AP. The method also comprises updating the system time with the memory time obtained from the flash memory. The method also comprises validating a server certificate received from an authentication server based on the system time. The system time is synchronized with a network time if the server certificate is successfully validated based on the system time. The synchronized system time is then written into the flash memory. In this way, the authentication can be performed based on a reasonable system time even if the AP reboots.

Abstract: Systems and methods are provided for a computing system for managing a mesh network deployment that includes a memory storing machine-executable instructions, and a processor configured to access the memory and execute the machine executable instructions to receive, link performance measurements from a plurality of access points in a mesh network, and determining a topology of the mesh network by: determining a first node competition index (NCI) for each interfering access point of the plurality of access points in the mesh network; comparing the NCI for each interfering access point to determine a maximum transmission time for each mesh link; and altering the network topology by assigning an active or backup mesh link to each access point based on the maximum transmission time for each mesh link.

Abstract: Implementations of the present disclosure relate to dynamic mesh service set identifiers (SSIDs). In the implementations, a first AP broadcasts a probe request including a first identifier and a first random number. The first AP receives a probe response including a second identifier and a second random number from a second AP. The first AP generates a first SSID based on the first identifier, the first random number, the second identifier and the second random number. The first AP transmits an authentication request including the first SSID to the second AP. The first AP receives an authentication response to the authentication request from the second AP. In this way, the mesh SSIDs associated with different mesh links are different so that other mesh APs would not be attacked even if a mesh SSID of one mesh AP in the same mesh cluster is exposed.

Abstract: In implementations of the present disclosure, there is provided a method for access point (AP) validation. The method comprises detecting a trigger event for validating a network including a plurality of APs, and selecting a target AP from the plurality of APs based on a neighbor table of an AP associated with the detected trigger event. The method further comprises determining a validation case corresponding to the detected trigger event from a knowledge base. The method further comprises sending the validation case to the target AP, and, receiving a result of performance of the validation case from the target AP in response to the validation case being performed. Implementations of the present disclosure can validate whether the network change takes effect in the network automatically, and can improve the validation efficiency of the network changes.
