      Finite state machine YANG model augmentation for Transponder
                            Reconfiguration
            draft-sambo-ccamp-yang-fsm-transponder-reconf-02

Abstract

   YANG enables to compile a set of consistent vendor-neutral data
   models for optical networks and components based on actual
   operational needs emerging from heterogeneous use cases.  A YANG
   model has been also proposed to describe finite state machine to
   program network elements that are modeled with YANG.  This document
   augments the more generic YANG model for finite state machine
   [I-D.sambo-netmod-yang-fsm], in order to pre-instruct an optical
   transponder on the actions to be performed (e.g., code adaptation) in
   case some events, such as physical layer degradations, occur.

1.  Introduction

   Networks are evolving toward more programmability, flexibility, and
   multi-vendor interoperability.  Multi-vendor interoperability can be
   applied in the context of nodes, i.e. a node composed of components
   provided by different vendors (named fully disaggregated white box)
   is assembled under the same control system.  This way, operators can
   optimize costs and network performance without the need of being tied
   to single vendor equipment.  NETCONF protocol RFC6241 [RFC6241] based
   on YANG data modeling language RFC6020 [RFC6020] is emerging as a
   candidate Software Defined Networking (SDN) enabled protocol.  First,
