Abstract: A disclosed method is performed at an access point including a processor and non-transitory memory. The method includes receiving a request message from a client device, where the request message includes a request for an allocation of a wireless channel for the client device from the access point. The method further includes exchanging candidate and load information with a plurality of other access points. The method additionally includes selecting a preferred access point from the access point and the plurality of other access points based on the candidate and load information exchanged with the plurality of other access points. The method also includes facilitating the allocation of the wireless channel for the client device from the preferred access point.

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: 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.
