Abstract: In one embodiment, a particular node in a primary DAG receives a distributed message from distributing nodes, and from this, deterministically selects a distributing node as a distributing parent in a secondary DAG from which distributed messages are to be received. The particular node may then inform the deterministically selected distributing parent that it is being used by the particular node as its distributing parent, and if the selected distributing parent is not the particular node's primary DAG parent, then the primary DAG parent is informed that it need not send distributed messages for the particular node. In another embodiment, a distributing node continues to repeat distributed messages in response to receiving notification that it is being used as a distributing parent, and if a primary DAG parent, prevents the repeating in response to receiving a notification from all of its child nodes that it need not send distributed messages.

Abstract: A multicast message may be distributed by receiving, at a first node in a multicast network, a multicast message from a parent node of the first node. The multicast message is transmitted to child nodes of the first node in the multicast network. A population of the child nodes to which the multicast message was transmitted is accessed and acknowledgement messages which reveal child nodes that are among an acknowledging subset of less than all of the child nodes of the first node are received. Child nodes revealed by the received acknowledgement messages are compared with child nodes determined to be among the population of child nodes to which the multicast message is expected to be received. Based on results of the comparison, a compressed non-acknowledging subset is identified and transmitted to the parent node.

Abstract: A parent node in a directed acyclic graph (DAG) in a computer network may detect congestion from its child nodes. In response, the parent node may determine particular child nodes to expel from the parent node based on the congestion, and notifies the expelled child nodes that they must detach from the parent node in response to dynamically detecting congestion (e.g., to find a new parent, excluding the parent node and optionally any nodes in the vicinity). In another embodiment, a child node receives a detach request packet from a current parent node that indicates that the child node is expelled from using the current parent node. In response, the child node triggers a new parent selection to select a new parent node that specifically excludes the current parent node (e.g., and optionally any nodes in the parent's vicinity).
