IETF Source Address Validation Improvements (SAVI) working group is
chartered for source address validation within the first hop from the
end hosts, i.e. preventing a node from spoofing the IP source address
of another node in the same IP link. However, since SAVI requires
the edge routers or switches to be upgraded, the deployment of SAVI
will need a long time. During this transition period, some
techniques for source address validation beyond the first hop
(SAVI-BF) may be needed to complement SAVI. In the document, we
analyze the problems of the current SAVI-BF technique, and discuss
the directions we can explore to improve SAVI-BF.
