   Distributed Denial-of-Service Open Threat Signaling (DOTS) Signal
                           Channel Call Home
                  draft-ietf-dots-signal-call-home-11

Abstract

   This document specifies the DOTS signal channel Call Home, which
   enables a Call Home DOTS server to initiate a secure connection to a
   Call Home DOTS client, and to receive attack traffic information from
   the Call Home DOTS client.  The Call Home DOTS server in turn uses
   the attack traffic information to identify compromised devices
   launching outgoing DDoS attacks and take appropriate mitigation
   action(s).

   The DOTS signal channel Call Home is not specific to home networks;
   the solution targets any deployment in which it is required to block
   DDoS attack traffic closer to the source(s) of a DDoS attack.
