摘要： In one embodiment, a network device determines a path from itself to a source device in a computer network, where the source device utilizes the path in reverse to reach the network device. Based on determining a reliability of the path in reverse, the network device may dynamically adjust one or more keepalive parameters for keepalive messages sent on the path. Accordingly, the network device may then send keepalive messages on the path based on the dynamically adjusted keepalive parameters.

摘要： In one embodiment, a particular node in a shared communication network determines a current path cost in a routing topology from itself to a root node via a current parent node. The particular node also determines a respective path cost from each reachable potential parent node of the particular node to the root node via each potential parent and a respective link metric to each potential parent node. A set of acceptable parent nodes are determined from the potential parent nodes that have a respective path cost that is less than the current path cost plus an acceptable cost increase, and also have a respective link metric that is within an acceptable range. By determining a respective number of child nodes for each acceptable parent node, the particular node may then select a new parent node based on giving preference to those having a greater respective number of child nodes.

摘要： In one embodiment, each device in a frequency hopping communication network operates according to a common broadcast schedule for the network that simultaneously overlays a configured portion of all independently determined unicast listening schedules in the network, wherein the overlaid configured portion is based on broadcast schedule parameters consisting of a first time spent for broadcast transmissions in each broadcast period and a second time between broadcast periods. By monitoring network characteristics relating to unicast traffic and broadcast traffic in the network, updated broadcast schedule parameters may then be determined based on the network characteristics. Operation of the common broadcast schedule may thus be updated with the updated broadcast schedule parameters, accordingly.

摘要： In one embodiment, a device, such as a network management server, determines a traffic matrix of a mesh network, where the traffic matrix indicates an amount of traffic per type of traffic transitioning between the mesh network and a global computer network via one or more current root devices. One or more optimized root devices may then be selected for corresponding directed acyclic graphs (DAGs) based on the amount of traffic and type of traffic. As such, a DAG formation request may be transmitted to the selected root devices, carrying a characteristic for a corresponding DAG to form by the respective selected root devices that indicates which one or more types of traffic correspond to the corresponding DAG.

摘要： In one embodiment, each device in a frequency hopping communication network independently determines its own local unicast listening schedule, and discovers a neighbor unicast listening schedule for each of its neighbors. The devices also synchronize to a common broadcast schedule for the network that simultaneously overlays a configured portion of all unicast listening schedules in the network. Accordingly, the device operate in a receive mode according to their local unicast listening schedule and the common broadcast schedule during the overlaid configured portion, and in a transmit mode according to each neighbor unicast listening schedule and the common broadcast schedule during the overlaid configured portion depending upon a destination of transmitted traffic.

摘要： In one embodiment, a device in a shared-media communication network determines a priority of a packet to be queued at the device, and based on the priority determines a length of time the packet is allowed to be queued before being successfully transmitted. After attempting to successfully transmit the queued packet within the shared-media communication network, in response to reaching a threshold amount of the length of time without having successfully transmitted the queued packet, the device may transmit a "shaping" request to one or more reachable neighbors in the shared-media communication network. Specifically, the shaping request is for a temporary reduction in bandwidth utilization by the reachable neighbors for traffic having a comparatively lesser priority than the priority of the packet.

摘要： In one embodiment, a control loop control using a broadcast channel may be used to communicate with a node under attack. A management device may receive data indicating that one or more nodes in a computer network are under attack. The management device may then determine that one or more intermediate nodes are in proximity to the one or more nodes under attack, and communicate an attack-mitigation packet to the one or more nodes under attack by using the one or more intermediate nodes to relay the attack-mitigation packet to the one or more nodes under attack.

摘要： In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.
