Abstract

   The control and management of DWDM interfaces are a precondition for
   enhanced multilayer networking.  They are needed to ensure an
   efficient data transport, to meet the requirements requested by
   today's IP-services and to provide a further automation of network
   provisioning and operations.  This document describes use cases,
   requirements and solutions for the control and management of optical
   interface parameters according to different types of single channel
   DWDM interfaces.  The focus is on automating the network provisioning
   process irrespective on how it is triggered i.e. by Element Manager
   System (EMS), Network Management System (NMS) or Generalized Multi
   Protocol Label Switching (GMPLS).  This document covers management
   and control considerations in different scenarios of single channel
   DWDM interfaces.  The purpose is to identify the necessary
   information and processes to be used by control or management systems
   to properly and efficiently drive the network.
