Assignee: CISCO TECHNOLOGY, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. One or more non-transitory tangible media encoded with logic for execution by a machine and when executed by the machine operable for:
generating, by the machine implemented as a network device, a destination oriented directed acyclic graph (DODAG) that is rooted by the network device, the generating of the DODAG based on outputting an instruction implementing multicast communication in the DODAG; and
multicasting a targeted packet that is destined for at least one targeted member device of the DODAG, the targeted packet causing sequential unicast communications in the DODAG,
wherein the targeted packet causes a router device in the DODAG to establish a unicast route for reaching the destination device within a prescribed limited number of hops, and
wherein the targeted packet is a unicast packet specifying a destination address encapsulated within a multicast packet specifying a multicast address, the at least one targeted member device operating as a destination device and processing the unicast packet in response to detecting the destination address associated with the destination device.
