Distributed-Denial-of-Service Open Threat Signaling (DOTS) Architecture
                    draft-ietf-dots-architecture-01

Abstract

   This document describes an architecture for establishing and
   maintaining Distributed Denial of Service (DDoS) Open Threat
   Signaling (DOTS) within and between domains.  The document does not
   specify protocols or protocol extensions, instead focusing on
   defining architectural relationships, components and concepts used in
   a DOTS deployment.
