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: 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: 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.

Abstract: In embodiments of the present disclosure, there is provided an approach for connecting an access point (AP) to a mesh network. According to embodiments of the present disclosure, an AP in a recovery mode transmits its identity information to a mesh portal (MPP) in the mesh network via an unsecured connection between the AP and the MPP. Upon a successful verification by the MP, the AP establishes a secured connection with a trusted server to obtain configuration information. The configuration information is used by the AP to establish a mesh link with an MPP or MP in the mesh network automatically. Accordingly, the AP switches from the recovery mode to a normal mode. Embodiments of the present disclosure provide an effective way for deploying and/or recovering an AP in a mesh network, which is more secure and requires no manual operation.

Abstract: In embodiments of the present disclosure, there is provided an approach for power saving in a mesh network. According to embodiments of the present disclosure, a mesh portal transmits, to a mesh point in a sleep mode, a packet for waking up the mesh point during a predetermined time period. The mesh point in the sleep mode detects the packet during the predetermined time period. In accordance with a determination that the mesh point is waked up, the mesh portal establishes a mesh link with the mesh point. Embodiments of the present disclosure provide an effective way for power saving in a mesh network.
