     Software-Defined Networking (SDN)-based IPsec Flow Protection
             draft-ietf-i2nsf-sdn-ipsec-flow-protection-09

Abstract

   This document describes how to provide IPsec-based flow protection
   (integrity and confidentiality) by means of an Interface to Network
   Security Function (I2NSF) controller.  It considers two main well-
   known scenarios in IPsec: (i) gateway-to-gateway and (ii) host-to-
   host.  The service described in this document allows the
   configuration and monitoring of IPsec Security Associations (SAs)
   from a I2NSF Controller to one or several flow-based Network Security
   Functions (NSFs) that rely on IPsec to protect data traffic.

   The document focuses on the I2NSF NSF-facing interface by providing
   YANG data models for configuring the IPsec databases (SPD, SAD, PAD)
   and IKEv2.  This allows IPsec SA establishment with minimal
   intervention by the network administrator.  It does not define any
   new protocol.
