Source Address Validation Improvement (SAVI) Framework
Abstract
Source Address Validation Improvement (SAVI) methods were developed
to prevent nodes attached to the same IP link from spoofing each
other's IP addresses, so as to complement ingress filtering with
finer-grained, standardized IP source address validation. This
document is a framework document that describes and motivates the
design of the SAVI methods. Particular SAVI methods are described in
other documents.
