摘要： In one embodiment, a data aggregator discovery (DAD) message may be distributed by an associated data aggregator, the DAD message identifying the initiating data aggregator, and comprising a recorded route taken from the data aggregator to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DAG through the recorded route and via the data aggregator. The receiving particular node determines a path cost increase (PCI) associated with use of the data aggregator based on the total path cost as compared to a DAG-based path cost for the particular node to reach the root node via the DAG. If the PCI is below a configured threshold, the particular node may redirect traffic to the data aggregator as source-routed traffic according to the recorded route. The traffic may then be aggregated by the data aggregator, accordingly.

摘要： 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.

摘要： 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.

摘要： According to one or more implementations of the disclosure, packets may be transmitted in a low power and lossy network (LLN) by receiving, on a first node, a message from a sending node, and by activating a critical message configuration to be applied in routing the message. A message identifier (e.g., signature) for the message may also be received or gleaned. The message identifier can be compared at the first node to a list of stored message identifiers, created based on routing history, to determine if the message has already been received. As such, if the message has not been received at the first node previously, a first parent and a second parent for the message are identified and the message, along with the critical message indication, can be transmitted to the first parent and the second parent, thereby achieving redundancy in the routing of the message.
摘要翻译： 根据本公开的一个或多个实现方式，分组可以通过在第一节点上从发送节点接收消息并且通过激活要应用的关键消息配置来在低功率和有损网络（LLN）中发送 路由消息。 消息的消息标识符（例如，签名）也可以被接收或收集。 可以将消息标识符在第一节点处与基于路由历史创建的存储消息标识符列表进行比较，以确定消息是否已经被接收。 因此，如果先前还没有在第一个节点处接收到消息，则识别该消息的第一个父节点和第二个父节点，并将该消息连同关键消息指示一起发送到第一个父节点和第二个父节点 从而在消息的路由中实现冗余。

摘要： In one embodiment, a security device receives one or more first unique identifications of packets sent by a first device to a second device for which a corresponding acknowledgment was purportedly returned by the second device to the first device. The security device also receives one or more second unique identifications of packets received by the second device from the first device and acknowledged by the second device to the first device. By comparing the first and second unique identifications, the security device may then determine whether acknowledgments received by the first device were truly returned from the second device based on whether the first and second unique identifications exactly match.

摘要： In one embodiment, a node in a computer network detects a misbehaving node in the computer network based on the misbehaving node acting in violation of one or more rules. As such, the node communicates information regarding the misbehaving node to a network management system (NMS), and then may receive isolation instructions from the NMS regarding how to isolate the misbehaving node from the computer network. Accordingly, the node may perform the isolation instructions. In another embodiment, the NMS receives the communicated information regarding the misbehaving node, and determines whether the misbehaving node should be isolated based on the communicated information. If so, then the NMS determines isolation instructions regarding how to isolate the misbehaving node from the computer network, and transmits them to one or more nodes in the computer network, accordingly.

摘要： In one embodiment, a device in a computer network monitors an alternating-current (AC) waveform of an electrical power source at the device, where the power source is part of a polyphase power source system. Once the device determines a particular phase of the polyphase power source system at the device, then the device joins a directed acyclic graph (DAG) specific to the particular phase. In another embodiment, a device detects a time of a zero crossing of the AC waveform, and may then determine a particular phase of the polyphase power source system at the device based on the time of the zero crossing relative to a corresponding location within a frequency hopping superframe of the computer network.
