    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: In one embodiment, a node receives a request to initiate a shadow joining operation to shadow join a field area router (FAR) of a computer network, and preserves its data structures and soft states. The shadow joining operation may then be initiated to shadow join the FAR, wherein shadow joining comprises preforming join operations without leaving a currently joined-FAR, and the node measures one or more joining metrics of the shadow joining operation, and reports them accordingly. In another embodiment, a FAR (or other management device) determines a set of nodes to participate in a shadow joining operation, and informs the set of nodes of the shadow joining operation to shadow join the FAR. The device (e.g., FAR) participates in the shadow joining operation, and receives reports of one or more joining metrics of the shadow joining operation measured by the set of nodes.

    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.
