Abstract: Techniques for improved networking are provided. An access point (AP) determines an AP duty cycle based at least in part on transmission activity of a station (STA) associated to the AP. The AP duty cycle is signaled via one or more beacon frames transmitted by the AP. The AP exchanges data in accordance with the AP duty cycle, comprising exchanging data with the STA during one or more active periods indicated by the AP duty cycle, and sleeping during one or more inactive periods indicated by the AP duty cycle.

Abstract: A method includes receiving, at a home controller of a home domain and from a first device in the home domain, a first message concerning a user device that is anchored to the home domain and that has roamed from the home domain to a visitor domain. The method also includes, in response to determining that the first device is a router, opening a tunnel between the home controller and a visitor controller of the visitor domain and communicating the first message to the user device through the tunnel. The method further includes receiving, at the home controller and from a second device in the home domain, a second message concerning the user device and in response to determining that the second device is not a router, communicating, to the second device, a proxy response to the second message.

Abstract: Protocol independent signal slotting and scheduling is provided by receiving a frame including a header and a payload for transmission; in response to determining that the frame matches a rule identifying the frame as part of a control loop, compressing the header according to the rule to produce a compressed packet of a predefined size that includes the compressed header and the payload; scheduling transmission of the compressed packet; and transmitting the compressed packet to a receiving device. In some embodiments, before compressing the frame, in response to determining that a size of the payload does not match a predefined size threshold: the payload is fragmented into a plurality of portions, wherein each portion satisfies the predefined size threshold, or the compressed packet is padded to the predefined size threshold via forward error correction padding information.

Abstract: Systems and techniques for dynamically optimizing a wireless network topology to minimize energy consumption while preserving user quality of experience (QoE) are described. An example technique includes determining a set of applications that have a target service level agreement (SLA). Network traffic is monitored from the set of applications being executed by one or more client STAs within a network. A topology of the network is dynamically adapted to reduce an amount of energy consumption in the network while maintaining a threshold amount of the network traffic that satisfies the target SLA, based on monitoring the network traffic.

Abstract: A source access network device multicasts copies of a packet to multiple core switches, for switching to a same target access network device. The core switches are selected for the multicast based on a load balancing algorithm managed by a central controller. The target access network device receives at least one of the copies of the packet and generates at least metric indicative of a level of traffic congestion at the core switches and feeds back information regarding the recorded at least one metric to the controller. The controller adjusts the load balancing algorithm based on the fed back information for selection of core switches for a subsequent data flow.
