Parent device shadow execution for a sleeping low power and lossy network child network device

An apparatus implemented as a physical machine, the apparatus comprising:

• non-transitory machine readable media configured for storing executable machine readable code;
• a device interface circuit configured for receiving a request via low power and lossy network (LLN);
• and
• a processor circuit configured for executing the machine readable code, and when executing the machine readable code operable for:
• generating and storing in the non-transitory machine readable media, by the apparatus implemented as a parent network device in the LLN, first state variables associated with a first execution state of an attached child LLN device during an active state of the attached child LLN device;
• determining the request is destined for the attached child LLN device and specifying a second execution state to be executed by the attached child LLN device;
• selectively updating, by the parent network device, the first state variables with second state variables associated with the second execution state in response to determining the second execution state identifies an updated execution state for the attached child LLN device;
• detecting, by the parent network device, that the attached child LLN device has transitioned from a sleep state to a second active state, and in response generating an instruction based on the second state variables;
• and
• transmitting the instruction to the attached child LLN device during the second active state, causing the attached child LLN device to execute the second execution state.

One or more non-transitory tangible media encoded with logic for execution by a machine and when executed by the machine operable for:

• generating and storing, by the machine implemented as a parent network device in a low power lossy network (LLN), first state variables associated with a first execution state of an attached child LLN device during an active state of the attached child LLN device;
• determining a request, received by the parent network device via the LLN, is destined for the attached child LLN device and specifying a second execution state to be executed by the attached child LLN device;
• selectively updating the first state variables with second state variables associated with the second execution state in response to determining the second execution state identifies an updated execution state for the attached child LLN device;
• detecting that the attached child LLN device has transitioned from a sleep state to a second active state, and in response generating an instruction based on the second state variables;
• and
• transmitting the instruction to the attached child LLN device during the second active state, causing the attached child LLN device to execute the second execution state.
