    Abstract: In aspects of packet segmentation and reassembly for mesh networks, a source node in a mesh network segments an access protocol data unit (PDU) into a set of segments that are concatenated with a segment transport header and transmitted over the mesh network in segmented access messages to a destination node. The destination node allocates memory to store the content of the access PDU based on a segment total field in the segment transport header, and stores each received segment at the appropriate offset in the allocated memory, based on a value of a segment offset filed in each segmented access message. The destination node transmits a segment acknowledgement message including a segment acknowledgement field indicating which of the multiple segments have been received by the destination node.

    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 for duplicate address detection, an end device of the mesh network can generate an address identifier that includes an address and time-based information associated with the end device, which is attached to a router device for communication in the mesh network. The address identifier is maintained by the router device as a tuple state of the end device. The end device or the router device can initiate an address query requesting that mesh network devices in the mesh network having a designated address respond with the tuple state that corresponds to the designated address. The end device or router device receives the tuple state of mesh network devices having the designated address in response to the address query, and can then detect a duplicate address of a mesh network device based on the time based information.

    Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data is an indication of a device identifier associated with a device that is allowed to join the mesh network. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network, and the steering data indicates that a commissioner is active on the mesh network. The commissioning device propagating the steering data enables the one or more routers to transmit the steering data in a beacon message, and the steering data is effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

    Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data includes an indication of a device identifier associated with a device that is allowed to join the mesh network, and the indication is represented as a set of values in a Bloom filter that represent the device identifier. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network. Propagating the steering data enables the routers to transmit the steering data in a beacon message, where the steering data enables the device associated with the device identifier to compare the set of values in the Bloom filter to a second set of values determined at the device to identify that the device is allowed to join the mesh network.

    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.
