Abstract
Systems and methods are provided for performing live upgrading of Access Points (APs) in WiFi-7. A method of upgrading an AP having Multi-Link Operation (MLO) and a Multi-Link Device (MLD) comprising a UMAC sublayer (MLD UMAC) and an LMAC sublayer (MLD LMAC), includes determining whether the MLD is in tunnel mode, and when the MLD is not in tunnel mode, switching the MLD to tunnel mode. Contents of the MLD UMAC are transferred to a controller; and contents of the MLD LMAC, comprising one or more MLD links, are transferred to one or more neighbor APs. Live upgrade of the upgrading AP is performed, after which the upgrading AP is rebooted. The MLD links previously transferred to the one or more neighbor APs are transferred back to the upgraded AP, and the contents of the MLD UMAC are copied from the controller to the UMAC of the upgraded AP.
