Abstract: In one example a computer implemented method comprises receiving, at an access point of a wireless network, a multicast/broadcast frame which identifies one or more stations associated with the access point as a recipient for the multicast/broadcast frame, and in response to a determination that at least one station of the one or more stations identified as a recipient for the multicast/broadcast frame is in an inactive state, determining a beacon slot time for a transmission of the multicast/broadcast frame from the access point, in response to a determination that at least one of the one or more stations in an inactive state will miss the beacon signal, converting the multicast/broadcast frame to a unicast frame, and holding a copy of the unicast frame to be transmitted to the at least one of the one or more stations in an inactive state that will miss the beacon signal.

Abstract: In one example a computer implemented method comprises estimating, in a processor communicatively coupled to a wireless client of a composite device, a first transmission time for an uplink beacon from a first access point communicatively coupled to the wireless client, scheduling, in the processor, a second transmission time for a beacon from a local access point of the composite device, and defining a scan window during which scan operations for the wireless client of the composite device and the local access point of the composite device are to occur, the scan window offset from the second transmission time by a first time buffer.

Abstract: An example of controlling a network of wireless access points (APs) to detect that a client device associated with the network is stationary in an AP-overlap area, and in response to the detection that the client device is stationary in the AP-overlap area, assigning one of the APs to be a preferred AP for the client device. The APs are to avoid connecting with any client devices that have been assigned another AP as a preferred AP. Thus, the stationary client device in the overlap area may be prevented from undesired roaming.

Abstract: Systems are methods are provided for implementing load balancing of IPsec security associations (SAs) SAs between different heterogeneous cores, for example in a multiple controller systems. The balancing of IPsec SAs are performed using software implementations of IPsec offloading and/or hardware implementations of IPsec offloading. By balancing the processing functions related to orchestration of IPsec SAs between hardware (e.g., IPsec hardware accelerator) and software (e.g., IPsec software accelerator), the methods realize increased optimization, improved user experience, and enhanced product performance in networks using IPsec. For example, an IPsec session is initiated, and it is determined whether a resource limitation for a hardware-based IPsec accelerator has been reached. If the limitation for the hardware-based IPsec accelerator has been reached, processing for the IPsec SA for the initiated IPsec session is offloaded to a software-based IPsec accelerator.

Abstract: In embodiments of the present disclosure, a method is provided for managing an AP position for an access point. In the method, a magnetic distribution map is obtained for an indoor area, the magnetic distribution map representing a plurality of reference magnetic values that are collected at a plurality of reference positions in the indoor area. A plurality of magnetic measurements are received, here the plurality of magnetic measurements are respectively collected at a plurality of access point (AP) positions at which a plurality of APs are deployed within the indoor area, and the plurality of AP positions are unknown. The plurality of AP positions are mapped to a portion of the plurality of reference positions based on the plurality of magnetic measurements and the plurality of reference magnetic values. The plurality of AP positions are determined based on the portion of the plurality of reference positions. Therefore, AP positions may be determined accurately and effectively in an indoor environment.

Abstract: Examples described herein relate to deferred authentication in secure boot systems. An untrusted component is identified in a boot sequence in a trusted execution environment. A secure boot authentication of the untrusted component is deferred for a predetermined period and access to hardware resources is restricted. An image digest and privilege rights including access to hardware resources associated with the untrusted component is obtained in an untrusted execution environment. A request including the image digest and the privilege rights is sent to a central node over a secure connection. A response including a signature based on image digest and approved privileges is received from the central node. The untrusted component is authenticated in the trusted execution environment using the signature before expiry of the predetermined period. Access to the hardware resources is provided to the untrusted component in the trusted execution environment based on the approved privileges.

Abstract: Examples of techniques for optimizing Neighbour Report (NR) are disclosed. In an example, a first virtual access point (VAP) operating in a 2.4 Giga Hertz (GHz) or 5 GHz band may determine a first Service Set Identifier (SSID) of the first VAP operating in a 2.4 GHz or 5 GHz band. The first VAP may identify a set of co-located VAPs operating in a 6 GHz band. The first VAP may filter the set of co-located VAPs to obtain a neighbour list comprising a second VAP, from the set, having a second SSID identical to the first SSID. Using the neighbour list, the first VAP may generate a Neighbour Report.
