Hello, I have some questions about draft-hou-roll-rpl-parent-selection-00 and draft-qasem-roll-rpl-load-balancing-01. In the draft,it describes a new type of metric which has this format: CNC: 8 bits. The Child Node Count is encoded in 8 bits in unsigned integer format, expressed in number count, representing the number of child nodes. MAX_CNC: 8 bits. The Maximum Child Node Count is encoded in 8 bits in unsigned integer format, expressed in number count, representing the maximum number of child nodes allowed in the neighbor cache. but it does not clarify if this number of child nodes refers to the number of direct child or the subtree size. In draft-qasem-roll-rpl-load-balancing-01: In LB-OF algorithm, the received DIO from the child node is counted by the preferred parent node. Each DIO contains the IP address of the chosen preferred parent as detailed in section 4.3. Thus, for each received DIO, the node matches its own IP address with the preferred parent IP address which is inserted in the DIO message, then increments the number of children by ONE for this node if there is a matching. My question is if that mean it will store the children's address and if yes,how will the node stores its children. The first draft https://tools.ietf.org/html/draft-hou-roll-rpl-parent-selection-00 The second draft https://datatracker.ietf.org/doc/html/draft-qasem-roll-rpl-load-balancing Best regards, Chenyang Ji
