摘要： 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.

摘要： In one embodiment, a network device along a path in a network receives a schedule that controls when the networking device is to insert telemetry data into data traffic passing through the networking device. The networking device generates the telemetry data for insertion into the data traffic passing through the networking device. The networking device inserts, according to the schedule, the telemetry data into a particular packet of the data traffic passing through the networking device. The networking device sends the particular packet to a next hop along the path in the network.

摘要： A method is provided in a wireless local area network controller in a wireless communication network. The wireless communication network includes one or more virtual networks identified with virtual network IDs, VNIDs. A request is received from a wireless client to onboard onto the network and the wireless client is mapped to an onboarding VNID. The onboarding VNID is associated with an onboarding virtual network that does not require an authentication of the wireless client. An Internet Protocol address assignment is forwarded to the wireless client. The wireless client is remapped from the onboarding VNID to the destination VNID after authenticating the wireless client. The wireless client maintains the assigned IP address after moving from the onboarding VNID to the destination VNID. Access to the wireless client on a virtual network identified by the destination VNID is provided via the assigned IP address.

摘要： 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.

摘要： 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.

摘要： 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.
