This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. The RPL path computation using ETXOF results in minimum-ETX paths from the nodes to the DAG roots, i.e., paths that minimize the number of packet transmissions for packet delivery from nodes in the network to the DAG root. This specification describes ETXOF, an objective function that minimizes ETX. The Routing Protocol for Low Power and Lossy Networks (RPL) allows the use of objective functions to construct routes that optimize or constrain a routing metric on the paths. The ETX metric of a wireless link is the expected number of transmissions required to successfully transmit and acknowledge a packet on the link.
