  Controlling Filtering Rules Using Distributed Denial-of-Service Open
                 Threat Signaling (DOTS) Signal Channel
                draft-ietf-dots-signal-filter-control-07

Abstract

   This document specifies an extension to the Distributed Denial-of-
   Service Open Threat Signaling (DOTS) signal channel protocol so that
   DOTS clients can control their filtering rules when an attack
   mitigation is active.

   Particularly, this extension allows a DOTS client to activate or de-
   activate existing filtering rules during a DDoS attack.  The
   characterization of these filtering rules is conveyed by a DOTS
   client during an idle time (i.e., no mitigation is active) by means
   of the DOTS data channel protocol.

Editorial Note (To be removed by RFC Editor)

   Please update these statements within the document with the RFC
   number to be assigned to this document:

   o  "This version of this YANG module is part of RFC XXXX;"

   o  "RFC XXXX: Controlling Filtering Rules Using Distributed Denial-
      of-Service Open Threat Signaling (DOTS) Signal Channel";

   o  reference: RFC XXXX

   o  [RFCXXXX]

   Please update the "revision" date of the YANG module.
