    • A communication system includes devices configured to communicate with each other via wireless communication by exchanging information in a sequence of time slots in frames. These time slots may be synchronized across the devices using distributed mutual synchronization in which each device exchanges time stamps in the frames with other devices to stabilize clock signals in the devices about a common frequency. Moreover, a time stamp in a given time slot may be generated by a transmitting device, which is transmitting in the given time slot, based on a clock signal in the transmitting device.

    • One embodiment of the present invention provides a system for facilitating multi-path load balancing at a local node in a network. During operation, the system measures a value for a metric on a local link which couples the local node to a neighboring node. In addition, the system receives from the neighboring node a neighbor path-metric value which indicates a value for the metric associated with all paths from the neighboring node to a destination node. The system then computes a “local path-metric value” for the metric associated with all paths from the local node to the destination node via the local link and the neighboring node. The system further computes a “packet-forwarding probability” corresponding to the destination node for each local link coupled to the local node, wherein the distribution of the packet-forwarding probability bears a nonlinear relation to the distribution of the local path-metric values for all the local links. The system subsequently forwards a packet destined for the destination node to one of the local links based on the computed packet-forwarding probability for that local link.
    • 本发明的一个实施例提供了一种用于在网络中的本地节点处促进多径负载平衡的系统。 在操作期间,系统测量本地链路上的度量值,该本地链路将本地节点耦合到相邻节点。 另外,系统从相邻节点接收邻居路径度量值,该值指示与从相邻节点到目的地节点的所有路径相关联的度量的值。 然后,系统通过本地链路和相邻节点计算与从本地节点到目的地节点的所有路径相关联的度量的“本地路径度量值”。 该系统进一步计算与本地节点耦合的每个本地链路的目的地节点对应的“分组转发概率”,其中分组转发概率的分布与本地路径度量值的分布呈非线性关系, 所有的本地链接。 该系统随后基于针对该本地链路的计算的分组转发概率将目的地为目的地节点的分组转发到本地链路之一。
