Abstract: In one embodiment, data packet messages are received in a Field Area Router (FAR) sent from one or more sources toward one or more destination devices in a Low-Power Lossy Network (LLN). An LLN routing topology for the data packet messages is interpolated in the FAR. An expected time for the data packet messages to reach a destination device in the LLN is determined based upon the routing topology interpolation. Traffic shaping is applied by thse FAR for the data packet messages based upon the determined expected time for the data packet messages to reach destination devices in the LLN.

Abstract: In one embodiment, a device in a network identifies one or more traffic classes used by one or more nodes in the network. The device determines routing requirements for a particular traffic class of the one or more traffic classes. The device generates a channel assignment that assigns the particular traffic class to a particular channel based on the routing requirements for the particular traffic class. The device provides the channel assignment to the one or more nodes. The one or more nodes use the channel assignment to route traffic of the particular traffic class within the network.

Abstract: In one embodiment, a device receives a router advertisement message after a power outage event in a network. The device joins the network, in response to receiving the router advertisement message. The device sends a power restoration notification message via the network. The device selectively delays a disconnected node from joining the network.

Abstract: In one embodiment, a device in a network identifies an upcoming network formation event. The device instructs one or more nodes in the network to use a network formation broadcast schedule during the event. The device determines that a degree of functionality in the network during the event exceeds a threshold amount. The device instructs the one or more nodes to use a normal broadcast schedule, in response to determining that the degree of functionality in the network during the event exceeds the threshold amount. Channels of the network formation broadcast schedule are active more frequently than channels of the normal broadcast schedule when in use.

Abstract: In one embodiment, a device in a network determines that one or more network nodes should use a stateful address configuration protocol to obtain network addresses. The device causes the one or more network nodes to use the stateful address configuration protocol, in response to determining that the one or more nodes should use the stateful address configuration protocol to obtain network addresses. The device determines that the one or more network nodes should use a stateless address configuration protocol to obtain network addresses. The device causes the one or more network nodes to use the stateless address configuration protocol, in response to determining that the one or more nodes should use the stateless address configuration protocol to obtain network address.

Abstract: In one embodiment, a device in a network detects a bidirectional traffic flow along a primary path in the network. The device determines that a self-interference condition exists along the primary path. The device selects an alternate path in the network. The device causes the traffic flow to use the primary path for packets of the traffic flow sent in a first direction and to use the alternate path for packets of the traffic flow send in a second direction that is opposite that of the first direction.

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 a plurality of nodes, a sender node dynamically selects a data packet for setting a transmission parameter request in response to determining that an age value for a set of transmission parameters associated with a recipient device has expired or is expiring. The sender node selects an desired data packet for sending a transmission parameter request and transmits the selected data packet to the recipient device. The sender node receives a transmission parameter response from the recipient node comprising updated transmission parameters for that recipient node and then updates the current transmission parameters associated with the recipient node accordingly.
