Abstract: In one embodiment, a method comprises: registering, by a root network device in a low power and lossy network, a constrained network device that is reachable within the low power and lossy network; obtaining, by the root network device, executable code associated with execution of a network service operation by the constrained network device; receiving a data packet from a source device and destined for the constrained network device; and causing execution on the data packet, by the root network device, of the network service operation on behalf of the constrained network device in response to reception of the data packet.
