Peer-to-peer optimization in existing tree-based topology based on generating locally-optimized tree using confined advertisements

摘要

In one embodiment, a method comprises determining, by a network device, a hop-by-hop path in a low-power and lossy network having a tree-based topology originated at a root network device, the hop-by-hop path comprising identified network devices for forwarding a data packet from a source network device to a destination device in the tree-based topology; and causing, by the network device, the destination device to initiate generation of a locally-optimized tree that bypasses the root network device and optimizes forwarding of the data packet from the source network device to the destination device, based on confined advertisements within the tree-based topology relative to the identified network devices.
