  Distributed Denial-of-Service Open Threat Signaling (DOTS) Telemetry
                      draft-ietf-dots-telemetry-00

Abstract

   This document aims to enrich DOTS signal channel protocol with
   various telemetry attributes allowing optimal DDoS attack mitigation.
   This document specifies the normal traffic baseline and attack
   traffic telemetry attributes a DOTS client can convey to its DOTS
   server in the mitigation request, the mitigation status telemetry
   attributes a DOTS server can communicate to a DOTS client, and the
   mitigation efficacy telemetry attributes a DOTS client can
   communicate to a DOTS server.  The telemetry attributes can assist
   the mitigator to choose the DDoS mitigation techniques and perform
   optimal DDoS attack mitigation.
