Abstract: A method includes obtaining client information from a set of access points. The client information indicates client devices detected by each access point in the set of access points. In some implementations, the method includes grouping the set of access points into a plurality of access point groups based on the client information. The grouping allows each client device to associate with an access point from at least two different access point groups. The method includes, for a first access point group of the plurality of access point groups, migrating the client devices associated with access points in the first access point group to access points in a second access point group of the plurality of access point groups. In some implementations, the method includes configuring the access points in the first access point group while maintaining configuration of the access points in the second access point group.

Abstract: Systems, methods, and computer-readable media for dynamically controlling an RxSOP threshold of an access point. In some examples, a current RxSOP threshold of an access point of a plurality of access points in a network environment providing wireless access to network services is determined. Wireless characteristics of one or more clients and the plurality of access points associated with the access point can be identified. Specifically, wireless characteristics of the one or more client and the plurality of access points in wirelessly providing and accessing the network services through the network environment are identified. The current RxSOP threshold of the access point can be dynamically modulated based on the wireless characteristics of the one or more clients and the plurality of access points.

Abstract: Systems, methods, and computer-readable media for reducing latency in TCP connections that utilize loss insensitive congestion control mechanisms. In some examples, packet arrival times for one or more TCP packets of a TCP connection are analyzed and based on the analysis, it is determined whether the packet arrival times are constantly spaced over a period of time. Whether a TCP control mechanism for the TCP connection is loss insensitive is identified based on whether the packet arrival times are constantly spaced over time. If it is determined that the TCP control mechanism is loss insensitive, then a total number of acknowledgement packets transmitted during the TCP connection and associated with transmission of the one or more TCP packets in the TCP connection is reduced.

Abstract: A method is performed by a first access point (AP) of a plurality of access points (APs). The first AP includes a non-transitory memory and one or more processors coupled with the non-transitory memory. In some implementations, the method includes determining traffic information for a first set of client devices that are being served by the first AP. In some implementations, the method includes obtaining traffic information for a second set of client devices that are being served by a second AP of the plurality of APs. In some implementations, the method includes synthesizing a unified traffic indicator map (TIM) based on the traffic information for the first set of client devices and the traffic information for the second set of client devices. In some implementations, the method includes transmitting the unified TIM to the plurality of APs. In some implementations, the unified TIM satisfies a network performance criterion.

Abstract: A wireless network system that provides for seamless roaming of client devices is described. The wireless network system includes a plurality of access points. One access point is designated as the primary access point that is responsible for handling encrypted communication with the client device. The primary access point has access to the necessary encryption key(s) for encrypted communication. The primary access point receives broadcast updates from the other access points that includes connection scores. When a connection score for a second access point exceeds the connection score of the current primary access point, the current primary access point designates the second access point as the new primary access point and sends the new primary access point the encryption key(s) for encrypted communication. The handoff is seamless and does not require a new handshake between the new primary access point and the client device.

Abstract: A dynamic channel selection approach for wireless communication networks is provided by measuring an ineffective communication metric on a currently-used channel. The network can switch channels if the ineffective communication metric from a device on the network satisfies a channel selection condition. To change the wireless communication network to the new channel, all network devices in the wireless communication network are instructed to switch to the new channel. As network communications start on the new channel, the ineffective communication metric measurements begin again on the new channel. Communications on the new channel continue until the channel selection condition is satisfied on the new channel, at which point another random selection of a channel is executed. The process continues in such iterations during the operation of the network and its network devices.

Abstract: Energy efficient transmission of content can be provided using a variety of techniques. In an example technique, portions of content can be transmitted from a first computing device to a second computing device for display. A wireless radio of the first computing device can be placed into a low power mode between transmissions of the portions of content. In another example technique, one or more portions of content can be decoded, displayed, encoded, and transmitted by a first computing device for mirroring on a second computing device. One or more other portions of the content can be transmitted in encoded format to the second device without being decoded and displayed by the first device. In another example technique, a wireless radio of a first device can be placed into a low power mode in between transmission of commands to a second computing device to control content.
