1.  Introduction

   This document defines a YANG module [RFC7950] for the management of
   the IP Traffic Flow Security (IP-TFS) extensions as defined in
   [I-D.ietf-ipsecme-iptfs].  IP-TFS provides enhancements to an IPsec
   tunnel Security Association to provide improved traffic
   confidentiality.  Traffic confidentiality reduces the ability of
   traffic analysis to determine identity and correlate observable
   traffic patterns.  IP-TFS offers efficiency when aggregating traffic
   in fixed size IPsec tunnel packets.

   The YANG data model in this document conforms to the Network
   Management Datastore Architecture defined in [RFC8342].

2.  Open Issues

   Currently, the only actively published YANG modules for IPsec are
   found in [I-D.ietf-i2nsf-sdn-ipsec-flow-protection].  This document
   attempts to use these models as a general IPsec model that can be
   augmented, however, in their current form this does not seem to be a
   good fit.  The models in [I-D.ietf-i2nsf-sdn-ipsec-flow-protection]
   provide for an ike and an ikeless model but the ike model
   intentionally does not include a Security Association Database which
   is a logical place for IP-TFS attributes.
