A Solution Space Analysis for First-Hop IP Source Address Validation
Ericsson
The IETF working group on Source Address Validation Improvements, SAVI, is chartered to design methods for IP source address validation that complement ingress filtering with finer-grained protection. This document summarizes the discussion in the SAVI working group and design-related conclusions. The purpose of this is two-fold: First, to guide the design process in the working group with written documentation of decisions and their rationale. Second, to provide a measure for assessing the IP source address validation methods that the working group will eventually deliver.
