Abstract:
IETF Source Address Validation Improvements (SAVI) working group is
chartered for source address validation within the first hop from 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.
