Abstract: Embodiments herein describe segmenting a Wi-Fi network into different groups. The embodiments herein assign a user, a client device, or a traffic flow originating from a client device to a group. For example, all the client devices for a particular user can be assigned to the same group tag, or each traffic flow in the client device may be assigned to different groups. Each group corresponds to a group key which can be transmitted to the client device when the device associates to an access point (AP). As such, within the same service set identifier (SSID), there can be multiple groups, and thus, client devices can use different group keys to communicate with other client devices associated to the same SSID. Put differently, rather than all devices connected the same SSID being assigned to the same group, the client devices can be assigned in different groups.

Abstract: The present disclosure provides techniques for handling MAC address collision within an ESS comprising at least one wireless station and at least one access point (AP). A wireless station selects a first Identifiable Random Media Access Control (MAC) (IRM) address, and sends the IRM address to the AP during execution of a handshake protocol. The wireless station receives a message from the AP indicating the selected IRM address is allocated for use by another wireless station. Responsive to the message, the wireless station selects a second IRM address different from the first IRM address, and transmits the second IRM address to the AP after execution of the handshake protocol. The wireless station uses the second IRM address in a subsequent association with the wireless AP or any other AP in a same extended service set (ESS) of the wireless AP.

Abstract: Techniques for facilitating client mobility without performing re-association are described. An example technique includes receiving, from a first access point (AP), an indication of at least one second AP neighboring the first AP. A multi-link association is performed. The multi-link association includes establishing a first link with the first AP and pre-establishing a second link with the second AP. After performing the multi-link association, the first AP is communicated with at a first instance in time via the first link.

Abstract: The present disclosure describes a system and method for deconflicting locally administered medium access control addresses (LAMAs). An apparatus includes a memory and a processor communicatively coupled to the memory. The processor receives a request for a client device to use a locally administered medium access control address (LAMA) and determines that the LAMA is in use or reserved for future use by an access point that is out of range of the client device. Prior to the client device roaming to the access point, the processor transmits to the client device a message denying connectivity to the client device using the LAMA. The message indicates a LAMA that the client device is prohibited from selecting.

Abstract: The present disclosure provides techniques for handling MAC address collision within an ESS comprising at least one wireless station and at least one access point (AP). An AP receives a first IRM address during execution of a handshake protocol between the AP and a wireless station. The AP determines that the first IRM address is allocated for use by another wireless station and then transmits a message to the wireless station. The AP receives a first wireless action frame transmitted by the wireless station after execution of the handshake protocol, where the wireless action frame includes a second IRM address selected by the wireless station. The AP establishes a wireless connection with the wireless station in a subsequent association with the wireless station using the second IRM.

Abstract: A client device may receive, from a computing device, a message indicating that a session duration of a current session is nearly over. The client device may close the current session as soon as the client device is idle for more than a configurable interval. A new session may be started with the computing device by the client device.
