Abstract: A wireless client device communicates, to an access point over a secure channel, a mapping of a dynamic device address to a stable device address. By communicating the mapping, the access point is able to determine that packets received from two different device addresses originate from a common device. The access point is then able to maintain an association between the originating device and other network resources assigned or allocated to the originating device, such as IP addresses or infrastructure station address, which is used to identify the originating device to other devices outside the network in some embodiments.

Abstract: A user device connected to a wireless network maintains session persistence through a MAC address change of a user device. The user device establishes a multi-path communication session including a first subflow associated with a first MAC address for the user device. When the user device changes from the first MAC address to a second MAC address. the user device establishes a second subflow of the multi-path communication session. The second subflow is associated with the second MAC address. After establishing the second subflow associated with the second MAC address, the user device ends the first subflow associated with the first MAC address.

Abstract: A wireless infrastructure that communicates with a DHCP server and a wireless client that rotates its MAC address performs a method including: upon receiving, from the wireless client, a first request with a first MAC address, creating a session context including the first MAC address and a stable identifier, and relaying the first request to the DHCP server; relaying, from the DHCP server to the wireless client, a first DHCP reply that includes an Internet Protocol (IP) address bound to the stable identifier; upon receiving, from the wireless client, a second request with the IP address and a second MAC address, merging the second MAC address and the IP address into the session context, and relaying, to the DHCP server, the second request including the stable identifier; and relaying, from the DHCP server to the wireless client, a second DHCP reply including the IP address bound to the stable identifier.

Abstract: The present technology pertains to identifying one or more sub-components of one or more network devices in a network environment; disaggregating the one or more sub-components from corresponding network devices of the one or more network devices; monitoring one or more functional flows across the one or more sub-components on a sub-component basis to generate functional flow data associated with the one or more sub-components; and generating analytics of the network environment on a sub-component basis from the functional flow data.
