Abstract: An example method of controlling a wireless access point may include associating accumulated-channel-resource-consumption variables with, respectively, resource consumers of the wireless access point. The method may further include, for wireless communications of the wireless access point determining a number of spatial streams effectively consumed by the respective wireless communication; determining an operational bandwidth effectively consumed by the respective wireless communication; determining a duration of the respective wireless communication; determining a channel-resource-consumption amount for the respective wireless communication based on the number of spatial streams effectively consumed by the respective wireless communication, the operational bandwidth effectively consumed by the respective wireless communication, and the duration of the respective wireless communication; and determining values for the accumulated-channel-resource-consumption variables by accumulating the channel-resource-consumption amounts per resource consumer. The method may further include determining whether to impose channel access restrictions on the resource consumers based on their respective accumulated-channel-resource-consumption variables.

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: 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: In implementations of the present disclosure, there is provided an approach for transmitting multicast frames. A method comprises obtaining a multicast frame in a wireless local area network (WLAN), where the WLAN includes a plurality of sub-networks with a same service set identifier (SSID). Then, a target sub-network of the plurality of sub-networks for receiving the multicast frame is determined based on the multicast frame and a unique group temporal key (GTK) for the target sub-network is obtained based on the target sub-network. Next, the multicast frame is encrypted using the obtained unique GTK for the target sub-network, and the encrypted multicast frame is transmitted to one or more client devices in the target sub-network. Implementations of the present disclosure can help the AP to reduce leakage of multicast frames to all client device by using the GTK corresponding the target sub-network.

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.
