摘要： Methods, devices, and machine readable media are provided for wireless client authentication and assignment. Some examples can include a network device with a processing resource and a memory resource storing instructions executable by the processing resource to act as a default gateway and present a web portal for logon in response to a request from a wireless client prior to authentication of the wireless client, to send a dissociation command for the wireless client in response to an initial authentication of the wireless client, and to assign traffic to a local virtual local area network (VLAN) defined on an access point (AP) associated with the wireless client in response to a subsequent authentication of the wireless client. Some examples can include assigning the wireless client to an isolation VLAN that is tunneled via the network device prior to dissociation, where the local VLAN is not tunneled via the network device.

摘要： A system enhances communications security in a wireless local area network (WLAN). The system includes a multiple antenna array arranged to transmit and receive signals; and a transmitter/receiver coupled to the multiple antenna array and configured to transmit and receive the signals. The transmitter/receiver includes a beamformer, which in turn includes a signal processor component that generates a signal beam for transmission to an intended user, and a blinding component that computes one or more blinding beams using only channel state information of the intended user. The blinding beams have a zero inter-user interference condition with the signal beam. The transmitter/receiver transmits the signal beam and the blinding beams simultaneously

摘要： Forwarding a flow in a network includes receiving the flow at a switch, determining an optimized priority queue level of the flow at the switch, and forwarding the flow via the switch using an optimized priority queue level of the flow at the switch. The flow passes through a plurality of switches, including the switch, in the network, and the optimized priority queue level of the flow at the switch is different from a priority queue level of the flow at a second switch of the plurality of switches. The second switch routes the flow at the second switch using the different priority queue level for the flow.

摘要： A wireless node receives a beacon from a wireless access point. The beacon includes a wireless protocol time synchronization function (TSF) timestamp generated with reference to a global clock for a network. The wireless node synchronizes a counter according to the TSF timestamp. The wireless node receives a global timing offset (GTO) packet from the wireless access point and combines the GTO packet with a counter value to generate a global timestamp.

摘要： Expected channel occupancy time is a wireless link metric determined based on a transmission protocol to be used for transmitting data in a wireless network. The wireless link metric may be used for routing or other network management functions. For determining the wireless link metric, an overhead is determined for one or more of accessing and releasing a channel to transmit a burst, including at least one frame, in the wireless network using the transmission protocol. An expected burst transmission time is calculated based at least on the overhead. The expected channel occupancy time is determined from the expected burst transmission time and an estimation of a number of frames to be successfully delivered during the burst.
摘要翻译：期望的信道占用时间是基于用于在无线网络中传输数据的传输协议确定的无线链路度量。无线链路度量可以用于路由或其他网络管理功能。为了确定无线链路度量，确定了使用传输协议在无线网络中访问和释放信道以发送包括至少一个帧的突发的一个或多个的开销。至少基于开销来计算预期的突发传输时间。期望的信道占用时间是根据预期的突发传输时间和在突发期间要成功传送的帧的数量的估计来确定的。
