A YANG Data model for ECA Policy Management
draft-wwx-netmod-event-yang-06
Abstract
RFC8328 defines a policy-based management framework that allows
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, Event
Condition Action (ECA) policy is an typical example of imperative
policy. This document defines a YANG data model for the ECA policy
management. The ECA policy YANG provides the ability for the network
management function (within a network element) to control the
configuration and monitor state change and take simple and instant
action on the server when a trigger condition on the system state is
met.
