         Controlling Filtering Rules Using DOTS Signal Channel
            draft-nishizuka-dots-signal-control-filtering-05

Abstract

   This document specifies an extension to the DOTS signal channel to
   control the 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 supposed to be conveyed
   by a DOTS client during peace time by means of DOTS data channel.
