    • In one embodiment, a node may determine a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node. As such, the node may generate a path clear message (PCM) that would instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration. After transmitting the PCM along the path to the particular node to establish the transmission priority for the priority traffic along the path through the shared- media network, the priority traffic may be transmitted to the particular node along the path during the transmission priority.
    • 在一个实施例中,节点可以确定用于在通过共享媒体通信网络的路径上建立传输优先级的触发,以用于到特定节点的优先流量。 因此,节点可以生成路径清除消息(PCM),其将指示沿着该路径的一个或多个接收节点在指定的持续时间内暂停除优先级业务之外的业务的传输,并且还发送本地非重复分布式 消息到每个相应接收节点的一个或多个邻居节点,该本地非重复分布式消息指示相邻节点在指定持续时间内暂停传输。 在将PCM沿着路径发送到特定节点以建立沿着通过共享媒体网络的路径的优先业务的传输优先级时,优先业务可以在传输优先级期间沿着该路径发送到特定节点。

    • In one embodiment, a particular node in a computer network, that is, one receiving electrical power from a grid source, may determine routing metrics to a plurality of neighbor nodes of the particular node in the computer network. In addition, the node also determines power grid connectivity of the plurality of neighbor nodes. Traffic may be routed from the particular node to one or more select neighbor nodes having preferred routing metrics, until a power outage condition at the particular node is detected, at which time the traffic (e.g., last gasp messages) may be routed from the particular node to one or more select neighbor nodes having diverse power grid connectivity from the particular node. In this manner, traffic may be routed via a device that is not also experiencing the power outage condition.
    • 在一个实施例中,计算机网络中的特定节点,即从网格源接收电力的一个节点可以确定到计算机网络中的特定节点的多个邻居节点的路由度量。 另外,节点还确定多个相邻节点的电网连接。 业务可以从特定节点路由到具有优选路由度量的一个或多个选择邻居节点,直到检测到特定节点处的停电状况,在该时间,业务(例如,最后一个喘气消息)可以从特定节点路由 节点到具有来自特定节点的不同电力网连接的一个或多个选择的邻居节点。 以这种方式,可以经由未经历停电状态的设备路由业务。
