    Abstract: 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.

    Abstract: In a multiple interface, low power and lossy network comprising multiple nodes, a root phase device obtains phase differential and absolute phase information from the devices in various network paths. Each device in a network path determines the differential phase data compared to its parent device in a network path. The device transmits the differential phase data to the parent device. The parent device transmits the differential phase data up the network path toward the root phase device. The root phase device collects the differential phase data and transmits the data to a central device. The central device determines the absolute phase of all devices. The root phase device can propagate absolute phase information to all devices within the network. Each device determines the absolute phase data by comparing the phase data of the device with the absolute phase data. The phase data is transmitted to a central device.

    Abstract: In one embodiment, first IP addresses are allocated to a plurality of nodes, respectively, in a computer network, the first IP addresses being routable IP addresses and specifically designated for routing packets in the computer network. At the same time, the plurality of nodes is allowed to submit a second IP address allocation request indicating a requested second IP address. In response to a second IP address allocation request from a particular node of the plurality of nodes, the requested second IP address of the second IP address allocation request is allocated to the particular node. The particular node is then allocated one of the first IP addresses and the requested second IP address. Also, a routing topology for routing packets in the computer network is constructed using only the first IP addresses.

    Abstract: Presented herein are techniques for securely configuring or managing devices in a variety of geographic locations. At a device manager for a device, a first public key of a first public-private key pair is presented to a network management system as part of a request for one or more work orders. The work order, generated and signed by the network management system using a second private key of a second public-private key pair, includes the first public key, and is received by the device manager. The signed work order is provided to the endpoint device for validation of the signed work order using a second public key, and all subsequent communications from the device manager to the endpoint device are sent such that the communications are signed with the first private key. In some embodiments, each work order is valid for a specified amount of time.

    Abstract: In one embodiment, a device that is protected against a power outage event in a network receives metrics used by a first node in the network to select a routing link to a second node in the network. The device stores the metrics used by the first node to select the routing link to the second node. The device selects a set of one or more of the metrics to provide to the first node during network formation after a power outage event in the network. The device provides the selected set of one or more of the metrics to the first node, wherein the first node uses the provided set to reestablish connectivity to the network.

    Abstract: In one embodiment, an alternating circuit (AC) power connected node in a shared-media communication network (with knowledge of a current time) determines a time value of a particular zero-crossing event of the AC power, and sends a message to a neighbor node indicating the time value of the particular zero-crossing event to allow the neighbor node to synchronize its time by coordinating the time value to its detection of the particular zero-crossing event. In another embodiment, the neighboring node determines one or more local zero-crossing events of the AC power, such that upon receiving the message indicating a correct time value of the particular zero-crossing event, the neighboring node can synchronize its local time a current time by matching one of the one or more local zero-crossing events to the particular zero-crossing event and assigning the correct time value to the matched local zero-crossing event.
