Technical Summary

   This document discusses multi-homing considerations for Distributed-
   Denial-of-Service Open Threat Signaling (DOTS). The goal is to
   provide some guidance for DOTS clients and client-domain DOTS
   gateways when multihomed.

Working Group Summary

The first version of the document was published as individual draft in June 2017.   The draft was adopted as WG document in January 2019, but received little attention from WG members until the fall of 2021, since the WG was busy with more urgent documents. The situation started changing after the WGLC for the document was issued and early reviews were requested which energized the discussion.

Document Quality

Document authors are also co-authors of core DOTS documents (signal channel, data channel etc.).  One implementation is known to follow the guidelines from the document.
