    Abstract: In one embodiment, a lower protocol layer in a network device filters packets based on a class and a particular of a destination address prior to sending information from the received packet to a higher protocol layer. For example, certain constrained networks include network nodes that do not have the ability to maintain a multicast distribution entry for each multicast address used in the network. By only forwarding on a portion of a multicast address, packets are often delivered to nodes in addition to the actual multicast subscribers. By filtering these incorrectly delivered packets at a lower protocol layer (e.g., layer-2 or layer-3), processing cycles at higher protocol layers are avoided. Additionally in one embodiment, class and particulars are deterministically determined (e.g., using a same hashing function) such that services can be discovered and used by subscribing to a corresponding multicast group.

    Abstract: In one embodiment, a network node provides a time slotted channel hopping (TSCH) schedule to one or more child nodes of the network node. The TSCH schedule includes one or more mandatory routing protocol report time slots. The network node receives routing protocol reports from the one or more child nodes according to the TSCH schedule. The network node aggregates the received routing protocol reports into an aggregated routing protocol report. The network node provides the aggregated routing protocol report to a parent of the network node during a time slot that is subsequent to the one or more mandatory time slots for the one or more child nodes.
