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). 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 only.
