Selecting the appropriate parents to achieve ultra-low latency and jitter requires information about a node's parents. This document details what information needs to be transmitted and how it is encoded within a packet to enable this functionality. This document also describes Objective Functions which take advantage of this information to implement multi-path routing.}, }
