Abstract:
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 source
address validation techniques beyond the first hop (SAVI-BF) may be
needed to complement SAVI and protect the networks from spoofing
based attacks. In this document, we first propose three desired
features of the SAVI-BF techniques. Then we analyze the problems of
the current SAVI-BF technique, ingress filtering. Finally, we
discuss the directions that we can explore to improve SAVI-BF.
