    摘要： The present disclosure is directed to networks having reduced power consumption characteristics and associated methods. In one aspect, a method for reducing power consumption in a multi-hop network can include receiving data at a plurality of primary nodes in a multi-hop network and transmitting the data from the plurality of primary nodes to a plurality of secondary nodes. Individual primary nodes have nearest neighbors at a defined distance and the secondary nodes are spaced at a distance that is greater than the defined distance away from individual primary nodes. Data is transmitted from a given primary node to a secondary node by skipping at least one intervening node and reducing power consumption of the wireless network.

    摘要： Methods, devices, and machine readable media are provided for transmission in a network with active and sleeping clients. Some examples can include transmitting a first multicast stream of data in response to an active wireless client being associated with the wireless network device at a particular time. The method can include transmitting a second multicast stream of the data after the first multicast stream in response to a sleeping wireless client being associated with the wireless network device at the particular time and in response to a delivery traffic indication message count expiring. The first and/or second multicast streams of the data can be retransmitted a number of times (e.g., at different data rates). An active/sleep status can be maintained for the wireless clients. A unicast stream can be transmitted when the number of clients does not exceed a threshold.

    摘要： A priority queue assignment technique for quality-of-service (“QoS”) network flows in a network is provided. A network path is determined for an incoming flow including a plurality of network switches associated, with a plurality of priority queue levels. A priority queue level is determined for the incoming flow for at least one of the plurality of network switches in the network path based on priority queue levels of existing flows. The priority queue level of the incoming flow is adjusted, to dynamically balance flows over the plurality of priority queue levels for at least one of the plurality of network switches in the network path based on quality-of-service (“QoS”) requirements associated with the incoming 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： 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.
