         DDoS Mitigation Offload: A DOTS Applicability Use Case
               draft-hayashi-dots-dms-offload-usecase-00

Abstract

   This document describes the applicability of DOTS to a DDoS
   mitigation offload use case.  This use case assumes that a DMS (DDoS
   Mitigation System) whose utilization rate is high sends its blocked
   traffic information to an orchestrator using DOTS protocols, then the
   orchestrator requests forwarding nodes such as routers to filter the
   traffic.  Doing so enables service providers to mitigate DDoS attack
   traffic automatically while ensuring interoperability and distributed
   filter enforcement.

1.  Introduction

   Volume-based distributed denial-of-service (DDoS) attacks such as DNS
   amplification attacks are critical threats to be handled by service
   providers.  When such attacks occur, service providers have to
   mitigate them immediately to protect or recover their services.

   Therefore, for the service providers to immediately protect their
   network services from DDoS attacks, DDoS mitigation needs to be
   automated.  To automate DDoS attack mitigation, it is desirable that
   multi-vendor elements involved in DDoS attack detection and
   mitigation collaborate and support standard interfaces to
   communicate.

   DDoS Open Threat Signaling (DOTS) is a set of protocols for real-time
   signaling, threat-handling requests, and data between the multi-
   vendor elements [I-D.ietf-dots-signal-channel]
   [I-D.ietf-dots-data-channel].  This document describes an automated
   DDoS Mitigation offload use case inherited from the DDoS
   orchestration use case [I-D.ietf-dots-use-cases], which ambitions to
   enable cost-effective DDoS Mitigation.
