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.
