Distributed Denial-of-Service Open Threat Signaling (DOTS) Data Channel
                             Specification
                    draft-ietf-dots-data-channel-26

Abstract

   The document specifies a Distributed Denial-of-Service Open Threat
   Signaling (DOTS) data channel used for bulk exchange of data that
   cannot easily or appropriately communicated through the DOTS signal
   channel under attack conditions.

   This is a companion document to the DOTS signal channel
   specification.
