Abstract: Protocol independent signal slotting and scheduling is provided by receiving a frame including a header and a payload for transmission; in response to determining that the frame matches a rule identifying the frame as part of a control loop, compressing the header according to the rule to produce a compressed packet of a predefined size that includes the compressed header and the payload; scheduling transmission of the compressed packet; and transmitting the compressed packet to a receiving device. In some embodiments, before compressing the frame, in response to determining that a size of the payload does not match a predefined size threshold: the payload is fragmented into a plurality of portions, wherein each portion satisfies the predefined size threshold, or the compressed packet is padded to the predefined size threshold via forward error correction padding information.

Abstract: In one embodiment, the locations of a plurality of network devices in a low power and lossy network (LLN) are determined along an intelligent wire. One or more neighboring devices for each network device in the plurality are identified based on the locations of the network devices along the intelligent wire. A communication schedule for the network devices is determined that prevents neighboring devices along the intelligent wire from transmitting on the same frequency. The network devices are assigned to communication time slots based on the communication schedule. The network devices are also assigned frequency offsets based on the communication schedule.

Abstract: A node in a Low power and Lossy Network (LLN) is managed by monitoring a routing configuration on a node in a LLN. A triggering parameter that is used to invoke an address change on a child node is tracked and a threshold against which to compare the triggering parameter is accessed. The triggering parameter is compared to the threshold. Based on results of comparing the triggering parameter to the threshold, it is determined that an address change at the child node is appropriate. An address change of a child node appearing in the routing configuration is invoked based on the determination that an address change is appropriate.
