    Abstract: In one embodiment, a tracking device detects a first device connecting to a computer network, and forces an install of fake routing information on the first device that is unique to the first device. Upon detecting a second device connecting to the computer network, the second device having at least one identifying property in common with the first device and at least one identifying property differing from the first device, the tracking device may then query the second device to determine if the second device knows the fake routing information unique to the first device. As such, the tracking device may then determine that the second device is the first device in response to the second device knowing the fake routing information unique to the first device.

    Abstract: In one embodiment, a scheduling device in a network receives routing metrics regarding a network path between a device controller and a networked device. The scheduling device also receives controller metrics for the device controller. The scheduling device determines time costs associated with the network path and one or more control operations performed by the device controller, based on the routing and controller metrics. The scheduling device generates a communication schedule based on the time costs and instructs the device controller and the networked device to use the communication schedule.

    Abstract: In one embodiment, an intermediate node in a contention-based shared-media computer network determines a scheduled window within which a packet (with an assigned priority) should be transmitted by the intermediate node. In particular, the intermediate node may specifically determine whether an actual transmission time is prior to, during, or after the window, and sets a priority of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window. As such, the intermediate node may then transmit the packet from the intermediate node with the set priority at the actual transmission time.

    Abstract: In one embodiment, a method comprises: receiving, by a parent network device in a directed acyclic graph (DAG) network topology, a data packet destined toward a DAG root and having been output by a target device in the network topology; identifying, by the parent network device based on the received data packet, an identifiable condition for caching a downward path enabling the parent network device to reach the target device independent of any route table entry in the parent network device; and caching, in the parent network device, the downward path enabling the parent network device to reach the target device independent of any route table entry in the parent network device.

    Abstract: In one embodiment, a device in a network receives a request from a neighbor of the device to add the neighbor as a child of the device in the network. The request includes a signed address registration certificate that certifies that a network address of the neighbor is registered in the network. The device determines whether the signed address registration certificate is valid. The device adds the neighbor as a child of the device in the network based on a determination that the signed address registration certificate is valid.

    Abstract: In one embodiment, a device in a network receives a notification from a neighbor of the device indicative of a child node of the device requesting a parent change from the device to the neighbor. The device updates an existing routing path from the device to the child node to be routed through the neighbor, in response to receiving the notification from the neighbor. The device receives an instruction to remove the updated routing path from the device to the child node through the neighbor. The device removes the updated routing path from the device to the child node, in response to receiving the instruction to remove the updated routing path.
