Abstract: Aspects of the disclosed technology address the problems of calculating and performing channel assignments for access points (APs) in a wireless network. In some aspects, a process for performing channel assignment can include steps for identifying multiple APs in a network, each of the wireless APs being associated with an initial channel assignment, selecting an AP from among the wireless APs in the network, determining a channel quality for the initial channel assignment associated with the AP, and selecting a new channel for the AP based on the channel quality. In some aspects, the process further includes steps for selecting a second AP, determining a channel quality for the initial channel assignment associated with the second AP, and selecting a new channel for the second AP based on the channel quality. Systems and machine-readable media are also provided.

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 storage media for automatic port identification. The present technology can involve determining that a wireless device has connected to a network device on a network, and determining which of the ports on the network device the wireless device has connected to. The determining the port connected to the wireless device can involve determining respective traffic patterns to be provided to selected ports on the network device, determining a traffic pattern transmitted by the wireless device, determining that the traffic pattern transmitted by the wireless device has a similarity to a traffic pattern from the respective traffic patterns, and based on the similarity, determining that a port associated with the traffic pattern is connected to the wireless device. The present technology can also involve selecting a port policy for the port.

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 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 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.

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.
