Abstract: Embodiments are directed to a fast path for acknowledgement frames in wireless networks. An embodiment of a storage medium includes instructions for operations including receiving frames at a network device via a wireless communication channel, each frame including a sequence number; holding the received frames in a reorder buffer to be reordered according to the sequence numbers of the received frames, wherein a frame is to be removed from the reorder buffer for delivery to a next process upon the sequence number of the frame equaling an expected next sequence number or upon expiration of a reordering timeout period for the frame; and, upon receiving an acknowledgment (ACK) frame, the ACK frame containing no data and having a sequence number that is later than any ACK frame that has been previously processed at the network device bypassing the reorder buffer for the ACK frame, and delivering the ACK frame to the next process, and maintaining an order position for the ACK frame in the reorder buffer until the reordering timeout period expires for the ACK frame.

Abstract: Techniques and systems perform link aggregation and fault tolerance across a wireless link connecting two wired networks. In a first example, a wireless networking device includes first radio and a second radio communicatively coupled to a wired network communication interface. The first and second radios have different operational parameters for bandwidth of transmission and other factors. The wireless networking device may include a processing device to cause the wireless networking device to establish a single data communication channel via the first radio; determine throughput of communication has been affected by an impact condition causing communication via the first radio to be impacted negatively and the second radio impacted positively. Based on that determination the single data communication channel may be transitioned to be received via the second radio. Each radio may maintain an active/backup status or perform load balancing to provide transmission of the single data communication channel.

Abstract: An example network device may include a processor to receive information of a set of devices including at least one network device; estimate interferences of available basic service set (BSS) color values in a specified channel, based on the received information; and select one BSS color value with the interference lower than others from the available BSS color values.

Abstract: An example method of controlling a wireless access point may include causing the wireless access point to identify any groupings of contiguous non-protocol FFT bins of a wireless channel in which all of the non-protocol FFT bins in the grouping have respective signal strength values exceeding a first threshold, and a bandwidth of the grouping does not exceed a second threshold. The method may also include causing the wireless access point to identify any resource units of the wireless channel that overlap with any of the identified groupings. The method may also include causing the wireless access point to, in allocating the resource units to client devices for an OFDMA communication, skip the identified resource units.
