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.

Abstract: In one embodiment, a device in a network receives one or more packets that are part of a traffic flow. The device provides a sample packet to a path computation element (PCE) that includes a signature that uniquely identifies the traffic flow. The device receives a traffic flow policy for the traffic flow from a policy engine and enforces the traffic flow policy for the traffic flow.

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 device in a wireless network receives a request from a node in the network requesting electrical power. The device determines one or more power transmission parameters for the node. The device determines a power transmission schedule for the node. The device sends wireless network communications to the node in response to the request and based on the determined one or more power transmission parameters and transmission schedule for the node. The node converts the wireless network communications into stored electrical power.

Abstract: In one embodiment, a device in a network determines whether a destination address of a packet received by the device is within a neighbor discovery (ND) cache of the device. The device determines whether the destination address is not in a set of addresses used to generate an address lookup array or possibly in the set of addresses used to generate the address lookup array, in response to determining that the destination address of the packet is not within the ND cache. The device performs address resolution for the destination address of the packet, in response to determining that the destination address of the packet is possibly in the set of addresses used to generate the address lookup array.

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, a device in a network sets a timer interval based in part on a distance between the device and a backbone of the network. The device receives a unicast communication destined for a remote destination that was sent via broadcast. The device determines a count of receipt acknowledgements of the communication sent by other devices in the network. At the end of the timer interval, the device sends a receipt acknowledgement of the communication via broadcast, in response to the count of receipt acknowledgements sent by other devices in the network being below a threshold amount.

Abstract: In one embodiment, a particular node operates a distributed routing protocol in a shared-media communication network, and distributes timeslot allocations using the routing protocol, where the particular node as a parent node allocates a pool of timeslots available to child nodes of the parent node. The parent node specifically allocates particular timeslots from the pool to particular child nodes according to particular flows from a source to a target in the shared-media communication network in order to meet a defined time budget for a resultant time-synchronized path from the source to the target.
