Internet-Draft draft-ietf-sidrops-bar-sav-02.txt is now available. It is a
work item of the SIDR Operations (SIDROPS) WG of the IETF.

   Title:   Source Address Validation Using BGP UPDATEs, ASPA, and ROA (BAR-SAV)

   Designing an efficient source address validation (SAV) filter
   requires minimizing false positives (i.e., avoiding blocking
   legitimate traffic) while maintaining directionality (see RFC8704).
   This document advances the technology for SAV filter design through a
   method that makes use of BGP UPDATE messages, Autonomous System
   Provider Authorization (ASPA), and Route Origin Authorization (ROA).
   The proposed method's name is abbreviated as BAR-SAV.  BAR-SAV can be
   used by network operators to derive more robust SAV filters and thus
   improve network resilience.  This document updates RFC8704.
