Abstract: In one embodiment, a method includes: transmitting a message to a first end point that includes an instruction to initiate a communication type, wherein the communication type includes sharing a randomization token between the first and second end points; obtaining a first communication report from the first end point and a second communication report from the second end point in response to initialization of a communication based on the communication type between the first end point and the second end point across the network, wherein the first and second communication reports respectively include a first and second hash that corresponds to a function of the randomization token and identity information; determining whether the first hash matches the second hash; generating a value that correlates the first and second end points with the communication across the network in response to determining that the first hash matches the second hash.

Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A location server can estimate a coarse location of a mobile device using a localization technique other than a UWB localization technique. The localization technique can involve multiple wireless access points or other radio devices. The location server can define an area around the coarse location to identify a set of candidate anchors for UWB ranging. The set of candidate anchors can be disposed within the area and include at least a subset of the radio devices. The location server can modify the set of candidate anchors to create a modified set of candidate anchors that includes only UWB-enabled devices. The location server can select a primary anchor from the modified set of candidate anchors and send a command to cause a UWB ranging procedure to be initiated between the primary anchor and the mobile 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.

Abstract: Best links for wireless clients may be provided. A computing device may receive, from a client device, a request to join a network. Then, in response to receiving the request to join the network, initial characteristics of the client device may be evaluated. Next, an initial plurality of links list may be provided to the client device in response to evaluating the initial characteristics of the client device. Subsequent characteristics of the client device may then be evaluated. An updated plurality of links list may be provided to the client device in response to evaluating the subsequent characteristics of the client device.

Abstract: Correlating devices and clients across addresses may be provided. A first address associated with a client device may be received. When the client device is not connected to a network, first location data associated with the first address may be obtained using a passive technique. A second address and second location data associated with the second address may then be obtained using an active technique. It may then be determined that the first location data and the second location data correlate. In response to determining that the first location data and the second location data correlate, it may be determined that the client device has changed from the first address to the second address.

Abstract: Techniques for utilizing a cloud service to compute an end-to-end SLA-aware path using dynamic software-defined cloud interconnect (SDCI) tunnels between a user device and an access point-of-presence (POP) node and inter-POP tunnels of the SDCI. The cloud service may include a performance aware path instantiation (PAPI) component including a POP database for storing performance metrics associated with the POPs of the SDCI, an enterprise policy database for storing user specific policies, and/or a path computation component. The path computation component may compute the path, based on the user specific policies, performance metrics associated with the POP nodes, and/or real-time contextual data associated with the user device and/or destination device. The path may include a first tunnel between the user device and the most optimal access POP node of the SDCI and a second tunnel between the access POP node, through the internal POP nodes, and to the destination device.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable media for using a sponsor as a proxy for multi-factor authentication of a first user account for a first user when a primary multi-factor authentication mechanism is unavailable to the first user account, comprising registering the sponsor in a multi-factor authentication chain of trust associated with the first user account; requesting verification of an identity of the first user from the sponsor; receiving, from the sponsor, a verification of the identity of the first user; and granting access to a service to the first user account.

Abstract: According to one or more embodiments of the disclosure, a device receives data regarding wireless communications between a wireless access point and a client. The device evaluates, based on the data, motion of the client relative to the wireless access point. The device makes, based on the motion of the client relative to the wireless access point, a determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point. The device adjusts the wireless communications, based on the determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point.

Abstract: In one embodiment, a first device coordinates probing of network paths that extend between an edge device and a data collection point via a plurality of points of presence. The first device receives a set of probing results that are indicative of one or more performance metrics associated with the network paths. The first device selects, based on the set of probing results, a particular point of presence from among the plurality of points of presence through which the edge device should send traffic to the data collection point. The first device instructs the edge device to send traffic to the data collection point via the particular point of presence.

Abstract: Access Point (AP) placement using Fine Time Measurement (FTM) may be provided. First, a plurality of Time-of-Flight (ToF) values between a first service end point and a second service end point may be determined. Each one of the plurality of ToF values may be derived from packets transmitted via different beamforming vector patterns at the first service end point and the second service end point. Then a minimum ToF value of the plurality of ToF values may be determined. Next, a distance between the first service end point and the second service end point may be determined based on the minimum ToF value.
