Abstract: A system and a method to dynamically reprovision network devices may include a first network device configured to reprovision a second network device in accordance with a specific location of the second network device in a predefined area. The first network device may be configured to sense the second device at the specific location in the predefined area, identify reprovisioning parameters associated with the specific location, and provide the reprovisioning parameters to the second network device. In turn, the second network device may be configured to perform one or more roles associated with the specific location in the predefined area based at least in part upon information in the reprovisioning parameters.

Abstract: A system and method are provided for allocating bandwidth and metering data flows within a wireless mesh-tree network. The network includes a wireless LAN controller (WLC), a root access point (RAP), and mesh access points (MAPs), which are arranged in respective hop levels corresponding to the number of links a given MAP is removed from the RAP. The WLC allocates available data rates (ADRs) to the respective MAPs, and each MAP then apportions its ADR among various origination types of data flowing through the given MAP (e.g., backhaul, ethernet-bridged, and client data types). The MAPs can use a token bucket filter (TBF)-like mechanism to enforce this apportionment. WiFi multi-media (WMM) based access classes can be used to shape the data flows (e.g., an NC access class assigned to topology maintenance traffic ensures it is fed directly into a WMM queue).

Abstract: In one embodiment, a mobile system scans wireless channels for any upcoming access points using a dedicated monitor radio of the mobile system. The mobile system identifies a particular wireless channel in use by an upcoming access point. The mobile system notifies a second radio of the mobile system of the particular wireless channel. The mobile system performs a handoff between a current access point and the upcoming access point in part by switching the second radio of the mobile system to the particular wireless channel of the upcoming access point.

Abstract: A method of updating map server entries may include generating a map server database (DB) at a map server. The map server DB may include a plurality of relational fields for a plurality of entries. The method may further include, based at least in part on a first entry of the plurality of entries being updated including a change to a first network location of the first entry, updating a second network location of a second entry of the plurality of entries that has a relation with the first entry based on the relational fields.

Abstract: Radio discovery for a mesh Access Point (AP) may be provided. Topology information associated with a first network may be received wherein the first network may comprise a mesh network. A Topology Descriptor Message (TDM) may then be created based on the topology information. The TDM may then be transmitted by a first Access Point (AP).

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: In one embodiment, a networking device receives packets of a traffic flow destined for a mobile system. The networking device sends a first flowlet of the traffic flow towards the mobile system via a first wireless access point. The networking device determines an idle time between the first flowlet and a second flowlet of the traffic flow. The networking device sends, based on the idle time, the second flowlet towards the mobile system via a second wireless access point.

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.
