This document specifies the Depth-First Forwarding (DFF) protocol for
IPv6 networks, a data-forwarding mechanism that can increase
reliability of data delivery in networks with dynamic topology and/or
lossy links.  The protocol operates entirely on the forwarding plane
but may interact with the routing plane.  DFF forwards data packets
using a mechanism similar to a "depth-first search" for the
destination of a packet.  The routing plane may be informed of
failures to deliver a packet or loops.  This document specifies the
DFF mechanism both for IPv6 networks (as specified in RFC 2460) and
for "mesh-under" Low-Power Wireless Personal Area Networks (LoWPANs),
as specified in RFC 4944.  The design of DFF assumes that the
underlying link layer provides means to detect if a packet has been
successfully delivered to the Next Hop or not.  It is applicable for
networks with little traffic and is used for unicast transmissions
