          Depth-First Forwarding in Unreliable Networks (DFF)
                         draft-cardenas-dff-10

Abstract

   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 RFC2460) and in
   addition also for LoWPAN "mesh-under" networks (as specified in
   RFC4944).  DFF assumes that the underlying link layer provides means
   to detect if a packet has been successfully delivered to the next hop
   or not, is designed for networks with little traffic, and is used for
   unicast transmissions only.
