Requirements for Security Services based on Software-Defined Networking
               draft-jeong-i2nsf-sdn-security-services-00

Abstract

   This document provides requirements for security services based on
   Software-Defined Networking (SDN) with two representative use cases:
   (i) centralized firewall system for intra-domain networks and (ii)
   centralized DDoS-attack mitigation system between inter-domain
   networks.  For the centralized firewall system, this document raises
   challenging issues in existing firewalls and a use case of
   centralized firewall system based on SDN.  For the centralized DDoS-
   attack mitigation system, this document also raises challenging
   issues in existing DDoS-attack mitigation techniques and a use case
   of centralized DDoS-attack mitigation system based on SDN.

1.  Introduction

   Software-Defined Networking (SDN) is a set of techniques that enables
   users to directly program, orchestrate, control and manage network
   resources through software (e.g., SDN applications).  It relocates
   the control of network resources to a dedicated network element,
   namely SDN controller.  The SDN controller uses the interface and
   arbitrates the control of network resources in a logically
   centralized manner.  It also manages and configures the distributed
   network resources and provides and abstracted view of the network
   resources to the SDN applications.  The SDN application can customize
   and automate the operations (including management) of the abstracted
   network resources in a programmable manner via this interface
