    Abstract: In aspects of automatic rerouting in Thread networks, a router device in a mesh network receives a packet to forward to a destination node, and the packet includes a Routing Locator (RLOC) for the destination node. The router device can determine that the packet cannot be forwarded using the RLOC. The router device can then initiate an address query over the mesh network, where the address query includes an Endpoint Identifier (EID) of the destination node. The router device can receive an EID-to-RLOC mapping for the EID from a node device in the mesh network, and forward the packet to the destination node using the received EID-to-RLOC mapping.

    Abstract: In embodiments of mesh network addressing, a router registers an address for an end device and assigns a child identifier to the end device. The router encodes an endpoint identifier of the end device, and a router identifier of the router into an Endpoint Identifier, which the router incorporates into a Routing Locator (RLOC) for the end device. The router responds to address queries and receives data packets on behalf of the end device. The router stores the data packets for the end device until the router can forward the data packets to the end device.

    Abstract: In embodiments of mesh network addressing, a router device receives provisioning domains that include an address prefix and an associated preference value for the address prefix. The router determines a route, based on one of the address prefixes, to use to forward a data packet to a destination. The router uses the preference values to prioritize the routing of the data packet. In other aspects, the preference values can be set based on one or more factors, and the router can use the preference values in addition to mesh network routing costs to determine a route for a data packet.

    Abstract: In embodiments of distributed coordination of mesh network configuration updates, pending commissioning datasets are managed and distributed to coordinate configuration changes of parameters that control participation in, and secure communication over, a mesh network. Pending network commissioning datasets are managed across fragmentation of the mesh network into multiple partitions and subsequent merging of the fragments to ensure that the most recent updates to pending commissioning datasets are propagated to mesh network devices and that all mesh network devices will receive pending commissioning datasets before the time that the pending commissioning dataset becomes the active commissioning dataset for the mesh network.

    Abstract: In embodiments of mesh network addressing, a router receives a packet to deliver to a network destination and determines if the network destination is within the mesh network. The network destination enables the router to discover a Routing Locator (RLOC) that is associated with the network destination and provides a routable network address for the network destination. The router can forward the received packet using the routable network address from the discovered Routing Locator. The router can discover the RLOC by searching a cache of RLOCs stored in the router, or by sending an address query.
