Abstract: In one embodiment, a service maintains a plurality of machine learning-based client behavioral models. Each behavioral model models wireless client behavior of a particular client type and configuration. The service selects one or more of the behavioral models to emulate the modeled one or more wireless client behaviors in a wireless network. The service controls, by using the selected one or more behavioral models, one or more emulation points in the wireless network to generate wireless client traffic in the wireless network that exhibits the modeled one or more wireless client behaviors. The service obtains performance metrics from the wireless network associated with the generated wireless client traffic.

Abstract: Embodiments for selective optimized roaming include receiving an indication that a connected device is at a cell edge of a first network. When an alternate access point cannot provide an alternate connection for the connected device, connections to other networks are assessed. This assessment includes receiving radio frequency (RF) signals for a second network and determining, from received RF signals, that the second network provides a better network connection. When the second network can provide a better network connection the connection to the first network is terminated.

Abstract: In one example embodiment, a first path computation element of a first segment routing domain includes a plurality of path computation clients. The first path computation element obtains, from at least one path computation client of the plurality of path computation clients, telemetry data indicating network traffic congestion for the at least one path computation client. Based on the telemetry data, the first path computation element determines that the at least one path computation client is experiencing at least a predetermined amount of network traffic congestion. In response to determining that the at least one path computation client is experiencing at least the predetermined amount of network traffic congestion, the first path computation element sends, to a second path computation element of a second segment routing domain, an indication of the network traffic congestion for the at least one path computation client.

Abstract: In one embodiment, a supervisory device in a network forms a first virtual access point (VAP) for a first node in the network. A plurality of access points (APs) in the network are mapped to the first VAP as part of a VAP mapping and the first node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device determines a communication schedule for the first node based on a radio chain of at least one of the APs in the VAP mapping for the first VAP being shared by the first VAP and a second VAP for a second node in the network. The supervisory device, according to the communication schedule for the first node, causes one or more of the APs in the VAP mapping for the first VAP to instruct the first node to stop transmitting for a period of time.

Abstract: A wireless access point that serves one or more wireless client devices in a wireless network determines that at least one particular client device that is associated to the wireless access point should not be associated to the wireless access point. The wireless access point transmits frames so that they are received at the particular client device with reduced strength so as to provoke the particular client device to transition from the wireless access point.

Abstract: Various implementations disclosed herein enable transforming mutable wireless coverage areas using network coverage vehicles (NVCs) that are orchestrated by a network coverage controller. In various implementations, the method includes receiving coverage area performance characterization values from NCVs configured to provide a plurality of mutable wireless coverage areas. In various implementations, an arrangement of the mutable wireless coverage areas mutably defines the service area, which changes in accordance with changes to the arrangement of the mutable wireless coverage areas. In various implementations, the method also includes determining NCV operation adjustments for some of the NCVs based on the received coverage area performance characterization values in accordance with a service performance metric; and, altering an arrangement of one or more of the plurality of mutable wireless coverage areas within the service area by providing the NCV operation adjustments to some of the NCVs.
