                 IPsec Key Exchange using a Controller
                 draft-carrel-ipsecme-controller-ike-00

Abstract

   This document presents a key exchange method allowing devices managed
   by a controller (e.g., an SDN management station) to create private
   pair-wise IPsec SAs without IKEv2 or any other direct peer-to-peer
   session establishment messages.

1.  Introduction

   Network architectures typically have included network devices
   directly communicating using network control protocols such as
   routing and signaling protocols.  Additionally, secured
   communications between these network devices are usually accomplished
   with a key agreement protocol such as IKEv2 [RFC7296], in which the
   network devices directly authenticate each other and agree upon
   security policy and keying material to protect communications between
   themselves.  However, controller-based network architectures
   (sometimes called "Software-Defined Networking") are now being
   defined [RFC7426] [RFC8192] and implemented.  In controller-based
