Abstract: Disclosed is a method includes treating, at an access point, a data flow between a first station and a second station during a first period of time as a non-fast flow. After a condition is met, the method includes marking the data flow as a fastACK flow during a second period of time and during the second period of time, storing data frames in the data flow at the access point to yield stored data frames. Next, the method includes generating a spoofed TCP acknowledgment signal on behalf of the first station and associated with the stored data frames and transmitting the spoofed TCP acknowledge signal to the second station.

Abstract: Systems, methods, and computer-readable media are disclosed for remotely managing and correcting implementation of configuration settings at network devices operating in the network. In one aspect of the present disclosure, a method includes transmitting, by a controller, a request to a network device of the network for a status of operation of the network device with respect at least one configuration setting available at the network device; determining, by the controller, whether the status matches an operation status provided by the at least one configuration setting; and performing, by the controller, a recovery process to adjust the implementation of the at least one configuration setting when the determining determines that the status does not match the operation status.

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: Disclosed is a system and method of a switchable, oscillating near-field and far-field antenna that may be used in access control systems. A controller is coupled to a transceiver, wherein the transceiver comprises an antenna module that includes both a near-field antenna and a far-field antenna. The near-field antenna is a subset of the far-field antenna, and the controller is adapted to cause the antenna module to oscillate between a near-field configuration and a far-field configuration while, for example, scanning an RFID tag of a wireless asset and receiving one or more return signals from the RFID tag, in order to determine a location of the wireless asset based on the one or more return signals.

Abstract: Systems, methods, and computer-readable media for steering authorized wireless clients to preferred or restricted wireless networks. In some examples, an access point associated with a preferred wireless network and a non-preferred wireless network can receive one or more probe requests from a wireless client. The access point can withhold a response to the one or more probe requests from the wireless client until a probe response triggering event is detected. In response to detecting the probe response triggering event, the access point can steer the wireless client towards the wireless network by sending, to the wireless client, a first probe response associated with the preferred wireless network and withholding a second probe response associated with the non-preferred wireless network.

Abstract: Systems, methods, and computer-readable storage media for automatic link security. A cloud controller can receive a signal indicating that an unauthenticated device is requesting private network resources, establish a connection between the unauthenticated device and the cloud controller, and determine that the unauthenticated device is associated with a private network. The cloud controller can facilitate the negotiation of security material between the device and the network and automatically establish a secure link between the device and the private network. The cloud controller can cause the security material to be sent to the device and can transmit a policy instruction that is effective to cause a switch port to automatically bypass a default access policy and automatically adopt a trusted policy for device to access the private network.

Abstract: Systems, methods, and computer-readable storage media for load-balancing are disclosed. An access point receives a communication request and an identifier from a wireless device. The access point determines a plurality of potential endpoints and selects at least one preferred potential endpoint for the wireless device, based on the identifier and the plurality of potential endpoints. The access point establishes a tunnel between the access point and the preferred endpoint for routing traffic associated with the wireless device.
