Abstract: Certain embodiments disclose systems and methods for creating a user private network (UPN) based on 11ay technology. Methods of the present disclosure include creating a personal basic service set (PBSS) having a service device and one or more 11ay devices, the service device configured to wirelessly communicate with the one or more 11ay devices in the PBSS, creating a UPN having an access point located in communicative proximity with the service device, and associating at least one 11ay device of the one or more 11ay devices with the UPN, wherein the at least one 11ay device is configured to establish a wireless connection with the one or more 11ay devices using the service device when within a coverage area of the PBSS, and to establish a wireless connection with the one or more 11ay devices using the access point when outside the coverage area of the PBSS.

Abstract: A method is provided to anonymize the media access control (MAC) address of a client device. The method involves generating a plurality of media access control (MAC) addresses for use by a client device in a network. Policies are defined that determine which one of the plurality of MAC addresses is to be used by the client device. The plurality of MAC addresses allocated for use by the client device are registered with a management entity in the network.

Abstract: In one embodiment, a method is performed. An interworking module of a wireless local access network (LAN) controller may receive a non-access stratum (NAS) message from an access point (AP) device using a control and provisioning of wireless access protocols (CAPWAP) tunnel. The NAS message may be translated to a WiFi service layer message. The WiFi service layer message may be sent to a wireless control plane module of the wireless LAN controller.

Abstract: A network management center includes a Dynamic Host Configuration Protocol (DHCP) server. The network management center obtains from an identity server, client information indicating authentication of a client device in a wireless network that is connected to a network fabric. The network management center obtains from an edge node in the network fabric an Internet Protocol (IP) address request for the client device. The IP address request including a fabric domain identifier associated with the edge node. The network management center allocates an IP address for the client device based on the client information obtained from the identity server and the fabric domain identifier contained in the IP address request obtained from the edge node. The network management center provides to the edge node an Identifier Locator Addressing (ILA) address based on the IP address.

Abstract: Embodiments are presented for collaborative device address generation between a wireless client device and a network infrastructure component, such as a wireless access point. The wireless client device and network infrastructure component share information to facilitate collaborative generation of a sequence of device addresses. This shared information includes, in some embodiments, key information and moving factor information. The key information and moving factor information is used to generate a token. A sequence of tokens is generated by updating the moving factor as each token is generated. A corresponding sequence of device addresses are then derived based on the sequence of tokens. Since the wireless client device and the network infrastructure device apply equivalent methods to generate respective sequences of addresses, the network infrastructure is able to efficiently identify a source wireless client device when observing a new device address on a wireless network.

Abstract: In one embodiment, dynamic user private networks are virtually segmented within a shared virtual network. A network control system maintains the dynamic logical segmentation of the shared virtual network. User entities (e.g., user devices and/or services) are communicatively coupled to respective personal virtual networks via endpoints of access devices. Each of these endpoints is associated with a corresponding user private network. Responsive in real-time to automated processing of a received electronic particular user request, the network control system automatically modifies the dynamic logical segmentation of the shared virtual network to move a particular user entity on the shared virtual network to newly being on the first dynamic user private network without being disconnected from the shared virtual network. One embodiment uses different user private network identifiers (UPN-IDs) associated with endpoints and received packets to identify their respective user private network.
