    Abstract: A network controller provides proactive notification of a wireless client device's address rotation to layer 2 (L2) and/or layer 3 (L3) devices. Traditional methods of device address discovery rely on broadcasting of address queries across a plurality of links until a path to a device having the queried address responds. As device address changes become more frequent in an effort to improve user privacy, traditional methods of address discovery impose a large burden on networks, reducing their performance and efficiency. By proactively propagating address changes to upstream devices, the need for broadcast oriented address discovery techniques is reduced, resulting in improved network performance.

    Abstract: In one embodiment, a device determines a hierarchy of layers of a network comprising a plurality of networking devices. The device configures, in response to a request by a client to access remotely a particular endpoint in the network, a proxy chain of remote access agents executed by a plurality of networking devices in the network to allow the client to access remotely the particular endpoint. Each of those networking devices proxies traffic between different layers of the hierarchy. The device determines an access policy for the particular endpoint indicative of which commands may be sent to the particular endpoint by the client, based in part on where the particular endpoint is in the hierarchy. The device controls, based on the access policy, whether a command sent by the client is transmitted via the proxy chain to the particular endpoint.

    Abstract: Various embodiments herein disclose coordinating neighbor discovery between access points (APs) with auxiliary radios and APs without auxiliary radios. A corresponding wireless controller comprises a processor and a memory storing instructions that, when executed, cause the controller to perform operations. The operations comprise grouping APs into a first group of more flexible APs and a second group of less flexible APs and querying the second group of APs for a corresponding broadcast interval. The operations further comprise identifying when the second group of APs is scheduled to broadcast parameters, and a broadcast interval for each AP of the second group of APs and generating a schedule based on the scheduled broadcast and the broadcast interval for each AP of the second group of APs. The operations additionally comprise providing the generated schedule to the first group of APs and the second group of APs.

    Abstract: Presented herein are techniques to optimize wireless local area network access point beam settings. A method includes, during a survey period, causing a first access point and a second access point in a wireless local area network, to simultaneously transmit survey transmissions according to a predetermined sequence of transmission states, receiving, from a survey station that received the survey transmissions during the survey period, telemetry associated with the survey transmissions, the telemetry including a location of the survey station when the survey station received the survey transmissions, and after the survey period, controlling, based on the telemetry associated with the survey transmissions, the first access point to operate according to a first transmission state from among the transmission states and the second access point to operate according to a second transmission state from among the transmission states.

    Abstract: A method comprises, at a wireless network controller of wireless access points through which wireless client devices that are wireless communicate with the controller: upon receiving, from a wireless client device, a dynamic host configuration protocol (DHCP) request having a media access control (MAC) address, determining whether the wireless client device rotated its MAC address from a previous MAC address to the MAC address; when the wireless client device rotated its MAC address, forwarding, to a DHCP service, the DHCP request with a notification of a MAC address rotation to cause the DHCP service to reassign a previously assigned Internet Protocol (IP) address to the wireless client device; and upon receiving, from the DHCP service, a DHCP offer asserting the previously assigned IP address, forwarding the DHCP offer to the wireless client device.

    Abstract: In one embodiment, a method includes receiving energy efficiency data from a plurality of nodes within a network. The method also includes determining an energy efficiency node quotient for each of the plurality of nodes within the network to generate a plurality of energy efficiency node quotients and determining an energy efficiency path quotient for each of a plurality of paths within the network to generate a plurality of energy efficiency path quotients. The method further includes determining one or more policies associated with the plurality of paths and selecting a path from the plurality of paths based at least on the plurality of energy efficient path quotients and the one or more policies.

    CPC classification number: H04W16/10

    Abstract: A method for adaptive presence-based radio configuration of access points in a venue includes defining a number of regions in the venue in which access points are deployed, each region having a center point, and assigning a first access point to a first region, positioned at the center of the first region. The method also includes affecting a first energy level in the first region, which corresponds to a power of a transmit signal emitted by the first access point, and assigning to the first region a configurable capacity value that determines an acceptable overlap constraint between the first energy level of the first region and an energy level of a neighboring region. The method further includes generating data describing a tessellation graph in which a possible map of the access points is formed using an iterative descent process based on the first energy level and the overlap constraint.
