              A YANG Data model for ECA Policy Management
                     draft-wwx-netmod-event-yang-04

Abstract

   RFC8328 defines a policy-based management framework that allow
   definition of a data model to be used to represent high-level,
   possibly network-wide policies.  Policy discussed in RFC8328 are
   classified into imperative policy and declarative policy, ECA policy
   is an typical example of imperative policy.  This document defines an
   YANG data model for the ECA policy management.  The ECA policy YANG
   provides the ability for the network management function (within a
   controller, an orchestrator, or a network element) to control the
   configuration and monitor state change on the network element and
   take simple and instant action when a trigger condition on the system
   state is met.
